Here is a farely simple way to connect your PSP to a GPS receiver:
http://deniska.dcemu.co.uk/images/psp_gps.JPG

You'll need:

- Holux GPSlim236 (~$100)
- Intec G6704 PSP Remote Control (~$11). Alternatively you can rip the connector of your original remote control.
- USB (Mini B) cable ($5-10) (don't use the included USB power cable)
- 1K 1/4watt resistor (>$1)
- Electric tape ($2 roll)

Tools:
- Soldering iron
- Multimeter (for checking the connector pins, alternatively you can use just a circuit made out of a low voltage bulb and a battery)
- Razor blade (to cut and clean stuff)


Basically, you just need to cut the USB cable and PSP remote plug, figure out which wires go to the connector pins, listed below, and connect them according to the diagram:
http://deniska.dcemu.co.uk/images/PSP_GPS_CONNECTION.jpg

Use caution when connecting the wires, make sure all of them are carefully insulated. You don't want to short any of them, since this may brick your PSP or GPS device.
Also, GPSlim 236 spec says that the TXD voltage may range from 3.2 to 5 V, so 1K resistor may not be enough to lower the voltage in some cases. So buy a few resistors: 5k,3k,2k,1k and see if your circuit works with a bigger value resistor first..

Once your cable is finished, test your setup with a little GPS viewer program that I wrote:

http://deniska.dcemu.co.uk/bin/gps_viewer.zip
The source code is included in the zip...
Note, the program is written to work in kernel mode, so I doubt that it will work on 2+ fw..
Perhaps someone can look in to how to adjust it...

Here is the screenshoot:
http://deniska.dcemu.co.uk/images/gps_viewer.JPG

So, waht's the point you ask? I am planning to plug this in to the upcoming map viewer applcation, which, of course will be able to point your gps location on a google-like map in real time... and scroll the map as you move along...

Special thanks to Art and futaris for helpping me out with serial port comm problems...

Almost forgot a disclaimer: As always, I am not responsible for any damages...

[EDIT]
The setup, described above, should also work with some older (and therefore cheaper) holux models: GR-230, GR-231. You can get those for ~45-60 bucks.

Freaking awesome.

Hey deniska, if you can do this this way then why cant we have a REAL tv tuner for the PSP :)

a couple of numbers through a serial port and a stream of television information are two completely different things. GPS information is realtively small but a TV broadcast requires a lot of bandwidth. A serial port can't provide that much.

Wally

O ok.
Thanks for verifying that with me :)

what about the USB port though?

deniska
July 25th, 2006, 04:54
O ok.
Thanks for verifying that with me :)

what about the USB port though?

In order to pull this thing through USB, PSP would need to be a USB host, This is something that it was not designed to be....
Most of periferials (including usb tv tuners and PSP) are usb clients, and clients can't talk to each other :-(


BTW, USB-like port in GPSlim 236 is not really a usb port.. they just use a mini B usb connector...

does this work with other gps devices too? or is it only for this 236?

deniska

It probably does, with some adjustments...
You'll have to look at particular device's spec to know for sure...
236 was picked because it's small, self-powered and could be used with other hardware - laptops, cell-phones, etc..

Thanks for the thanks Deniska...

NMEAp (http://www.dmh2000.com/nmea/nmeap.shtml) looks like a simple easy to use NMEA parser... In the long run, it might be better to use GPSd and libgps (http://gpsd.berlios.de/). It would allow us to connect to an external GPS and/or share GPS data through WLAN, etc...

Anyhow, probably more important to get KML, KMZ or GPX parsing working once maps are up and running.

nice. thank you for confirmung my research about the compatibility of the gps devies :D

i ordered myself a 231 today. i will tell you if it works =)

btw.. do i need to recode your testing programm? wouldnt be that problem, but knowing it, before testing and find it not working would be better^^

I don't think you need to recode anything...
From what I remember, 231 has exactly the same interface spec...

this is actually pretty kewl stuff :)
I remember when a friend and I built a security system(shool told us so), all from scratch.
This was the very first time we used a microcontroller :)
I think I'll buy a microcontroller programmer for my own personal use ;)
Basically the microcontroller checked a applied voltage, (can't remember the pin) and if it goes under a certain value it sends AT commands through the serial port to the modem and a sms was sent :)
The whole developing stuff was quite entertaining ;)
We also created a PCB for it :)

keep it up deniska ;)
I think I'll buy a similar GPS thing ;)

Can someone recompile this for 4800 baud? Please?


I am in the process of educating myself on how to use the SDK, but I want to play with my gps/psp!

I mananged to make an EBOOT with the bitrate changed to 38400, but it was full of errors.

I couldnt get it to work.

I tried a Pharos GPS-360 that I had on hand. It came with MS Streets & Trips 2005. Its SIRF-II based, 3.3V-5.5V input. Output is 4800 8N1 TTL 0-2.5V.

The cord had already been hacked up (It has a PLL serial-usb device in the cord). I had used this when I was playing around with APRS last year, so I am very familiar with the pinout of this unit & so forth.

I powered the reciever separately with 5vDC, and connected GND and TX from the GPS to pins 2, 6 on the PSP. When the GPS is powered, the TX voltage starts fluctuating between 0-2.5V. (It does send sentences even if no satellites are seen)

I tried it with no resistor, & a 1k resistor, but the program sits at "please connect gps to psp"

What is the default bit-rate for the PSP?

Surely the data that the GPS is spitting out is interoperable with the PSP.....

Take a look at this, its dated but relevant for sure:

Try to use the serial echo prog, included with lua player... see if you can get anything on a screen with it...

I opened a copy of the serial app. that came with lua in Notepad, and changed the 2400 to 4800, saved it to the psp, and now Im getting text that is more like NMEA sentences now.

It appears to be skipping characters, much like the situation you were describing with your setup, except I think it may be LUA-based, I remember reading something from 'Art' on another forum about speed limitations with the LUA-players' SIO.

I'll keep plugging away at it, dont let me distract you from your Mapping project.

Lua is slow amd has it's limitations, but at least you know that your cable works...
I suggest that you figgure out what's wrong with your pspsdk setup, change and recompile my application (try to just print out characters, that it reads w/o parsing them in to structures... see if you can get full NMEA sentenses.. currently, it looks like the parser cannot validate the checksum....

Ok I finally found a tutorial on setting up PSPSDK that actually had links to the correct files/libraries.

I merely changed the bitrate in your GPSVIEWER program (Not the modified one you posted yesterday)*, recompiled it, and executed it. Im getting correct gps data in all fields.

The GPS-360 is a great reciever to play around with, considering you can get them dirt cheap, its small, and has that cool blue LED glow :) Im picking up 3 satellites inside my living room with the reciever about 6 ft away from the window.

I look forward to trying your mapping project when it becomes available!

* you may want to delete that modified GPSviewer you posted here for me, I never could get it to run.

Good stuff, man!
Sorry for that program.. I must have changed something else there, while experimenting... Well, I am glad you figured that one out...
Perhaps you should start another thread, showing how to hook GPS-360 with the PSP. Some people may appreciate it...

As to the map viewer, I am still pretty far from a public release, but I may need a few testers in a week or so to start trying in on the streets...
So PM me if you want to help - I'll hook you up with the source code....

i bought a Holux GPSlim236 yesturday it should be here either tomorow most likely . im trying to do the cable i got all the parts for it, but im kinda lost on the port on the gps unit, is that port a usb b port? if so that would mean from my usb b cable the red wire will go to pin 2 on the psp and the green wire from the usb will go to pin 6 on the psp with 1k resistor between?
can someone correct me plz

lewbacca

get a multimeter and check the pinout..
the colors mean nothing.

you can see the pins which u have to use on deniskas pictures.

I just did this with a Garmin GPSmap 60C, works a charm :D
Didn't need any resistors, either. Just had to recompile with 4800baud - I can give the eboot to anyone who asks.
Btw Deniska: Be sure to put in "selectable baud rates" in your mapping program, not everyone knows how to recompile. ^^

i own a Microsoft gps, will it work?, i am totally new to this. how am i going to know which wire link to which end? if i am right then there is only going to be 2 wires that need to be rewired? will i be able to run microsoft map on there?
or even micro softs pocket PC map? will it work with 2.6 or higher?

how am i going to know which wire link to which end? you can check the pinout with the hardware specification paper. or google searching
if i am right then there is only going to be 2 wires that need to be rewired? yes. using deniskas method gps wiring is fairly easy
will i be able to run microsoft map on there?nope

or even micro softs pocket PC map?nope
will it work with 2.6 or higher?
deniska should tell ya if it runs on 2.6.. but higher = no

You are correct, currently, the gps functionalityrequires certain calls, only available on 1.0-1.5 fw
About the device, compatibility: it should work with all gps devices, which support serial comm port and NMEA protocol..

yes i can i also found that when i was going about 56 the psp would read out 45 it was always around this number of differ when going fast. im starting to think its with the setup maybe, cuz i also used the gps reading program that has the green background to it and i found it was about the same thing. i might charge the battery of the gps unit and hook it up to my laptop and re do the speed testing.

maybe we can narrow it down with the help of f n noob's speed read out from both gps programs with the use of his gps 360 http://www.dcemu.co.uk/vbulletin/images/icons/icon1.gif

I got it figured out.. I did not read the NMEA spec carefully.. the speed is posted in KNOTTS.. I already made adjustments to the code to make the speedfix configurable so you can convert it to MPH or KPH

I've been following this thread for a wile now. Iím completely amazed with your work and also with the PSP capabilities Ė theyíre endless! This is also my first post in DCemuÖ

Well Iím convinced to buy a GPSlim236 (nice choice too) just donít want to rip the original remote and donít seem to find a replace nearby (Portugal), seems I have to order onlineÖ The hook-up is so dam simple that it even hassles me!

Donít want to get you out of coding dept. but why donít you free a pre-release, even though, without the source code if you donít think is ready yet for general public? Iím not censoring you or something just canít wait to get my hands on itÖ Or, your strategy is going to aim for a commercial route (couldnít blame you, eitherÖ)?

If I build the set-up (as soon as I get the partsÖ) could you hook me up with your soft?

Now for the Beta testers (especially LEWBACCA, A Fn NOOB and SEESOE):

Could some of you make a small tutorial of how to use the scripts for map generation (and other info you find usefull), to enlighten other users and free DENISKA of doing so?

Tank you all!

I decided to enter this program in to a coding competition, and the rules say that it must be the first public release.... So just wait a bit more...
I believe the deadline is Aug 20...

Hope to, by Aug. 20, already have my GPS&cable, if not sooner.

@Seesoe
I only requested that because Deniska already did request help (to keep him focused in coding) and it would be a great help for those starting with this tool when the public release is out… I don’t think it (map gen) will mutate that much as of the public release, or will it?

Don't know if time is important enough to be in large font... I put it in. mostly for debugging purposes: as timestamps for NMEA data - to make sure it's changing and up to date...

To my beta-testers (you know who you are) : I dumped the new version at the same location.
I did some changes to gps read&parse logic, so let me know if it still works with different gps units..
While in GPS mode you can toggle "TRACK UP" by pressing RIGHT arrow. You can capture your NMEA sentenses to gps.txt file by pressing LEFT arrow.. (to replay it, you'll need to change FAKEFEED variable in config.txt

i notice that you power the gps unit from the psp, whereas the developer who uses the gps unit i own connects it to an external power source... is it possible to power the gps360 via the single cable, as you do here..? if so, what wires do i need to connect for the power..? will i need a resistor..?

many thanks - i apologize if these questions are basic, and i appreciate any input and or advice.

the psp will not give enough power to power a gps unit from the serial port. the Holux GPSlim236 used in this setup here has its own battery. the one you have gps360 does not have a battery it gets its power from the usb when u plug it into the computer.

Hi, Just saw the videos of this that hit all the PSP news sites today, Must have been on vacation the firs time around to have not seen this project sooner. I just ripped up my PSP's Remote cable, i never use it anyway so it's not close to a huge deal, And i had the problems getting that damned plastic insulation or whatever they put around the connectors, and it ripped the wires. I'm hoping someone can clue me in on what colors go where, and which are actualy Used. If a Big picture can be supplied it would help a bit more. I'm Partialy Color blind so the small pictures are a bit difficult for me to tell the diffrences on the cables. One i found seems to show only the GND and Blue are being used? Is this true? If so which destinguishing color is the ground? thanks.

As I said before, I do not recommend to make any connections based on color of the wires...

Buy/borrow a multi-tester @ radioshack (or any electronics parts store) and measure the resistance between the cable connector pins and the wires on the other side of the cable...
I bought my tester at radioshack and returned it next day... ;-)

You can even create a "tester tool" yourself out of a small low voltage bulb, 2 wires and a battery...

like deniska said..
when i soldered my wires, i didn't even see a difference between 2 colors. it is very much safer if you test the wires before. everything else could result in a brick :/

seesoe
August 13th, 2006, 20:25
crater i was also like you if your read the thread i asked for colors so i can hook my gps up, i just used my 10 dollar multimeter i got a while ago at radio shack, and if you noticed i didn't solder my cable up, if you want to do the same you will have to strip your psp remote very carful don't stech the cable or anything it will just make it harder to strip the inside wires, instead just get a sharp blade and use that to strip the outer wire. now the kinda hard part the inside wires are very small and they are coated with this streachy metiral, use ur teeth, get a good grip on the wire, but not to hard where when you pull it will rip the main wire* and pull. if you do this right you should be good to go. thats what i did do it at your own risk im not responsible if you mess anything up

i know i dont want to use the one that comes with the gps 'cos that's the one that interfaces with the charger, but could i use any othr mini-usb cable i have lying around...?

do they all have that big cap/knob on them (behind the mini usb plug, after a short length of cable, and then cable continues on the other side), and should i leave the cap attached, and then cut into the cable, or should i get rid of the big cap/knob..?

Well any type of USB miniB should work... keep in mind that the usb connector on the HOLUX ain't got nothing to do with usb... its a camouflaged serial+charging connection.

The cap/knob usually conceals a ferrite core, it should act like an buffer/filter to avoid signal loss and degradation (remove EMI/RF), for this purpose it should work well without it (anyone correct me if I'm wrong...)

You might get some advantage of using those if you're in to high quality audio reccording somehow (e.g., minidisc's), or to comply with FCC or other standards...

Deniska is the best person to answer this but from what I've read and tested with the scripts here provided (as is), its not possible, right now, retrieve data from Sweden from Google maps (to street or road level), probably whit some tweaking that could be possible... Deniska can correct me if I'm wrong

About the radars - don't know if they could be entered as point of interest (POI), provably can, but don't know how the map viewer would react to them (a proximity alarm would be good...) perhaps in a 2nd phase Deniska will be more receptive to functionality requests from users ;-) or others/yourself may upgrade the source code to suite their/your needs...

Hey Deniska,

I got my GPSlim236 yesterday and made a cable in about an hour.

Only problem is I can't get it to work with your Map This! program.

I tried your old green screen GPS viewer program and that works fine.
I just don't know what I'm doing wrong.

I edited the config file to turn off the fake NMEA info.
But the display just says bad data.
I noticed the checksum value thingie for beta testers. Do I need a certain value or something?

Otherwise, great program. Certainly the best homebrew I have ever seen.
Any help appreciated.

WIFI off, UMD out, GPS position fix, but still no luck.

Just strange that it works fine with the old GPS viewer but not with Map This!

For the record, I made the PSP serial connector out of an old ISA card.
The cable is 1.5 metres long.

Maybe Map This! has more strict data transmission standards than GPS viewer?

I might try making a shorter cable and see if that works.

Finally got it working, turns out you need to have something inserted into the adjacent headphone socket.
Of course, anyone using a normal combo connector wouldn't have had this problem but my ghetto connector is just a bit of PCB jammed in to the serial port.

I'm still not sure how a change in resitance would make a difference?

Do I need to apply power to the cable? If the resistance changes, how does that tell me which pin is which?

Sorry i'm a mechanical engineer not an electrical one ;)

EDIT:

I understand it now. Use the pinout to identify the correct pin and put the multimeter on the end of the wires to find out which wire belongs to which pin. Thanks :)

Anyone, and I mean, anyone can build a conductivity meter from 2 stripes of wire 1 battery and 1 LED...

just simply connect 1 stripe to the negative pole of the battery, connect the positive pole (longer lead) of the LED to the positive pole of the battery and finally connect the other stripe to the negative pole of the LED - thatís it!

Now whenever you connect both ends to a conducting peace (close the circuitry) the LED must light up and you know which is connected were...

I don't think you'll get many takers on that offer.

The materials alone cost more than $10. So you're basically asking someone to buy you a remote cord, a mini-usb cord, do all the work and shell about $15 out of their own pocket for you, not including shipping.

Here's a list of what's needed for materials as a reminder:
- Intec G6704 PSP Remote Control (~$11).
- USB (Mini B) cable ($5-10)
- 1K 1/4watt resistor (>$1)
- Electric tape ($2 roll)

However, if you're going to supply all the materials and pay for shipping both ways you might get someone to do it.

By the way, you double posted this over here (http://www.dcemu.co.uk/vbulletin/showthread.php?t=32582&page=10).

GPSlim 236 has a pretty wide TX voltage range (3-5) range. yours is probably close to 3 V..
To be on a safe side, you may want to try putting 500 Om resistor just to me on a safe side...

Sorry for my bad english !
But im german!!!
Thak you for this Great Tool for the PSP....

And thanks already for help to get it work on my PSP!!!

well, first your doubling your post's: that won't bring more help... then, if you find which are the RxD (receiver) on the phone pinout, like I told you before, you'll know were is the TxD on the GPS... that's the only thing you'll need besides GND (ground).

And no,I dont think that you can power the GPS from the PSP, you can try though, but even if you can it'll drawn all power from PSP's battery in no time!

If you need mobility apart from your car I would advise you to manage how to find the output voltage from that adaptor and try to adapt it to work with batteries... it's a lot of work but for ppl into DIY thst's nothing ;-)

here you should find the pinout:

I wrote in the other Thread that I will post here to keep the other Thread clean!!!

So.. Thank you for your Help....

I looked on the pinout on the Connector which I plug in into the Mobile Phone..

I pursed the solderpoints on the connector to the Pins and now I know what Wires are for what....

I found the TxD wire and the GND ....
And I know which wire is for the PowerSupply...

But as I wrote the GPS device is getting his Power over the 12V Connector in the CAR!!

Now I need to know if I need a Restistor between the Powerwire of the 12V Plug and the Powerwire of the GPS Module!?

On the PowerConnector is written :

Input: 12/24V
Output: 500mA +- 50mA


I hope this info helps!!

I will make Pictures of the connector an the GPS inside

Thank you for your Help!

My guess is that your PowerConnector is a transformer that converts 12/24V to lower voltage rating to your cell phone or GPS...

Let me ask you this: you can use your gps only with the cell phone (without adaptor)?

- if so, you must know the voltage ratings from the phone to GPS and, this way, probably you can use a siemens cx65 battery to power up the gps without the phone

- if not, you're geting power from the adaptor: use a multimeter to find the voltage rating from the adaptor to see if it can be repaced with a battery.

You know that the schematic with the resistor is only to normalize voltages to data communicationn... if you want to power the GPS I'd advise you to use the adaptor until you find a way to attach a battery to it

You're on your own, now...

This is so cool by far the best homebrew I have seen I voted.

Also I ordered a Holux GPS 236, I bet you made the MFG happy with all the people with PsP's ordering one.

I have a quick question about the cable and the resistor. I want to make the cable before my GPS unit arrives. Just so I make sure when I create the cable i understand the multimeter part to figure which cable go to which pins. What I don't understand is the voltage part.

Do I measure the voltage when i hook the cable up to the Holux unit ? So I wooul touch the pin on the mulitmeter on one end with teh Hloux hooked up on the other ? And this voltage should read ~2.5v ? Not over or under correct ?

Also I am just connecting 2 wires total ?

Thanks for any help guys keep it up.

The voltage (if you want/need to check) could be read between GND and TxD with the GPS on... Usually, you only need this for troubleshooting or when using a different setup/device

the resistor is only used to lower the voltage from the GPS unit to PSP RxD rating - I think it's about 2.5v.

Yes, you only need 2 wires (unilateral communication: GPS -> PSP).

Hello, between the TxD you probably will - that depends on the output voltage from the GPS trough the transmiter (TxD) line - It's better to check it with a multimeter before troubles happen.

I must have missunderstood you: I thought you where talking about resistors to adjust voltage to power the GPS...

You dont need to recompile the program there's a config file were you can set that (and other stuff needed)

I've used the 1kOhm resistor... but the MapView don't get any Data from the GPS... now I am looking for someone who can compile the GPS App with the green color which shows all the infos of the GPSdevice whith my Baud for testing!!

The GPS Device gets Power from the 12 V Connector in the Car... the GPS Device is after a couple of minutes warm.... because of that i'm sure that the GPS device gets his Power!

so... now I will solder the TxD directly without any Resistor... maybe thats the problem!!!

thank you for compiling it.....

But when I plug the connector to the PSP the Programm says that I need to connect and switch the GPS on....

could it be that the App is waiting for Datareceive on throug the PSP connector and then it knows that the connector is connected with the PSP!

So.. it could be that the sending of the data is prevented by the resistor...

I'm looking to get a Multimeter somewhere...!!

Yes, since communication is unidirectional it is waiting for some signal on PSP serial port.

You need to disconnect WIFI switch, and leave UMD off the tray (at least the other version don't work with)

You may need to wait for proper data

I have some questions about your testings:

Did you put and select the map for your exat location in germany - I dont think so! and if it's says OUT OF RANGE its because it CAN get a LAT/LONG!!!!!!!! so your first setup must have worked...

No, R is the resistor value in Ohm...

500mA was a guess, for demo pourpose only... don't know that for sure... probably is a bit high and thus less conservative. I may have to advise you to go for a lower one: 200 or 250mA giving a resitor of ~1KOhm

Tried to check that in ps2dev but the site is down...

P.S.: That formula is known as Ohm's Law ;)

Hi guys, I got my gpslim236 receiver today, and I've had trouble getting it to work. I made the cable as directed and have tested it with a multimeter. When I use the green screen app, I can see NMEA sentences popping up every second or so, but the Longitude and Latitude values (among others) aren't showing up.

I tried measuring the voltage between pin1 and pin3 on the gps device, and it says its 3V. But when I hook up the cable (with the 1k resistor) and measure it, the voltage stays the same. Could that be the problem? Isn't the voltage supposed to drop because of the resistor?

Keep in mind that your multimeter would probably display just an average voltage for that AC current...
The danger comes from peaks that could be higher than 3V...
The multimeter would not show the peak voltage, because it's not just fast enough for the transmission frequency... for that reason you probably wont see the drop on your resistor, but your PSP just might feel it...

yep, your gps did not lock on any satelites yet..
it takes ~40sec for GPSlim to get the lock in clear skies, assuming your dont move the unit during the acquisition period.
The time is GMT (assuming it had a lock, overwise it's some garbage)

If you continue having difficulties locking on satelites, consider changing the unit. Unfortunately, there are reports of many defective gpslim236 units outthere...
The good thing - your communication part & cable work ok ;-)

I don't think you can get an accurate voltage reading with a multimeter in this case... the idea is to start with high resistor values (say, 5K) and keep lowering the resistence until you get a stable reading...

Yeah, psp could probably tolerate the GPSlim236 output level in most (if not all cases), but I placed the resistor in in the public drawing just to make sure it is safe, and noone bricks the PSP because of this...

I read recently that the some of the components on TA-082 motherboards operate on 1.8VDC vs 3.3VDC for TA-079, 80, 81 mobo's.

It may not be applicable for the serial port though, but you may want to make a cautionary note to TA-082 people to use caution, as I think there is a downgrader coming for those motherboards.


I imagine it will be possible to get data from USB for the Sony GPS unit. I wonder how they could prevent homebrew from accessing the USB?

The benefit to our setup is that we can use the Camera AND the gps at the same time!


I think the next version of MapThis should have a "show tracks", "save tracks", "erase tracks" feature.

Also, I mentioned a while back about an "Open" mapping project at Sourceforge. It's www.OpenStreetMaps.org (http://www.OpenStreetMaps.org) It appears to be in the early stages.

Also TigerMaps is (US) a server that has free (but dated 1998) maps.

Ive got MS Streets and Trips on my laptop, that has the entire US streetmaps + poi's etc and it takes up 936mb of space. The map "data" folder is ~900mb.

What are the legalities of making a program that uses the map data of software that you legally own on a platform that it was not written for?
(Ive also got Garmin Mapsource too)

Which leads me to one more question:
There are tons of emulators of other gaming consoles for the PSP. Legalities aside, would it be theoretically possible to emulate some of the commercial GPS-Navigation units on the PSP?
I think the PSP has all the processing and graphics abilities, including voice prompting (And theoretically voice commands (Look at Talkman)). The only thing not available is touch screen. (Unless an external overlay were developed).


Densika, Thank You for making MapThis!

i agree i think with enough hardware and programing work, the psp can emulate. the mic part would not be that hard, but maybe the part of haveing the headphone jack plugged in and not get sound out of speakers *if im niot mistaken someone from this forum is testing out how to get the sound from usb? with those docking stations, i forget exactly what it was he gonna try* touchscreen overlay is not needed just a waste of codeing and money for the overlay and hardware hack

On my Original Sony Remote the GROUND was the BLUE wire and the TxD was the GREY Wire ......

but it could be that it's different on your Remote.....

Anyway Try to find out which wire belongs to GROUND and wich WIRE to TxD.....

jhuh I dont think you have done anything wrong as far as I can tell. You are soldering to the headphone plug.

The easiest way I found to make sure you have the right wires on the usb side is just to rip the covering off the large usb plug you removed and use a pinout diagram to see which color wire is conected to which pin

Probably not, because most probably hacked their remote cable to connect. The sound 'hole' is what makes that thing stay put, otherwise I dont think it would stay in place otherwise. There is no reason why you cant get sound (out) though. The wires going to 7,8,9 are audio. When a headphone is inserted into the round hole, it enables 2.5V DC on pin x (I forget which pin without referring to diagram)
So that it can power an external device.


All the info on serial port can be found at

Hello,

I feel like I'm 90% there with this hookup on a Garmin eMap (circa 1998). That GPS supports (allegedly) NMEA @ 4800 baud. It's a 3V device. The pinouts are very easy.

I've hooked one up following roughly the outlines Deniska and others have posted. Apparently no resistor is required, and the PSP *does* get data on the serial port (I used gpsviewer, recompiled with 4800 baud setting).

My problem is that the data is just a bunch of deterministic, repeating high-bit ascii characters which are obviously not NMEA sentences.

I noticed that others have had this same problem -- any help or advice you could offer me? I'm wondering if I've recompiled the proggie wrong @4800 -- you just change the pspDebugSioSetBaud() statement right? Do you also have to modify the sceKernelDelayThread(20) in the loop to get accurate timing?

Again, thank you for listening -- hopefully someone has the silver bullet -- til then, I'll keep hacking away til it works :)

Can u post a screenshot of the output with "greenscreen"?

Do you have specs for the unit handy?

Search the site for a version of greenscreen I posted up for 4800 baud, its on here somewhere, but I think out in the News forum.

Sounds like either your unit is configured for other than 4800, or bad compile. But getting it working in "Greenscreen" first is the best thing to do, so you can rule out config problem with the reciever. (Maybe greenscreen :) could integrated into MapThis to aid in configuring one day)

Also some GPS specs make it confusing as to which pin is RX & TX...... Make sure that:


GPS TX ---> Serial RX


If the data appears to have some consistency ( Like repeating similar characters every 20 secs) look at the bitrate.
If it doesnt, maybe wires are crossed.

Edit: I didnt realize that it was a handheld (as opposed to a gps-'mouse'... I bet there is a menu in it's GUI to change from it's native Garmin protocol to NMEA sentences. Most likely the problem.

ZeroAltitude
September 12th, 2006, 02:35
Hi there,

Thank you for the quick reply! It is possible the wires are crossed, but the consistent visible data seems to indicate that might not be the issue. I have made sure in the setup program to set it to NMEA (it was the default, but you're right there are other protocols, some Garmin proprietary).

If I can't get it working in a few more go-s, I'll see if I messed up the wiring (I did (try?) to do TX > RX as specified -- I'll have to look at the specs again maybe!).

Thank you again, and if you get any other thoughts, I'll be watching this thread intently!

Heres what Id do to rule out the wiring first

Get luaplayer, it has a serial port program included that gives raw data from serial port. It is limited to 2400 baud though. No problem, set your emap to text output and 2400 baud.

Thats just what Id do. Im assuming the emap will let you change baud in some protocols like my Garmin Etrex does, from 1200 to 9600. NMEA is locked at 4800 on the EtrexLegend. 4800 seems to be the industry standard speed for most GPS's. (4800 baud is also the default speed of the PSP serial port, I recall)

Then look for a post by my where I included the EBOOT where I changed it to 4800, it works for sure.

Good luck... you'll have this solved in no time.

ZeroAltitude
September 12th, 2006, 04:09
BINGO! I *think* one of Deniska's wiring diagrams on his site might be wrong: I reversed the wires (GPS TXD > PSP pin *2* -- listed as GND, I believe maybe RX and GPS GND > PSP pin *6* -- listed as RX, I belive maybe GND?)

Either that, or the Garmin spec is wrong >< (i *was* getting - voltage when using my multi in a way i thought should give + voltage)

Either that, or I'm dyslexic :))

Now it works! Thank you so much for your patience and help NOOB and Deniska (on another thread).

To sum up:

Garmin eMap
Wire pin 3 to PSP pin *2*,
Wire pin 4 to PSP pin *6*,
no resistors needed,
set Setup to NMEA 4800
and voila

I am glad it worked out for you...

I think my diagram is correct though..
at least there are a few more sources (aside from obvious "it works for me") confirming the pin layout..
This is just one of them:
http://nil.rpc1.org/psp/files/PSP%20Serial%20Converter.pdf

I hope you'll be able to hook it up with MapThis! (if you have not already done so)
You may need to get the latest eboot from friday (attached to one of the threads here) to make it work - since I increased the NMEA buffer for "slow baud devices"...

just make sure it's for data transfer...some power cables (motorolla phones power chargers, etc) have same connector, but don't have all data wires inside the cable, to make it thinner...

Try to run it with serial port echo program distributed with lua player for PSP and see if you get any data at all...
You may also try pin5 (RXD) instead of pin 6 - recieve/transmit could be confusing since it's not clear which end-device they specify it for GPS or PC.

How did you measure the signal amplitude? - most cheap testers would not give you the correct results - since they may be too slow for the frequency of the signal... btw, psp would need 2.5V signal, but again your device probably have 3V if not higher output.. so use caution...

Use that cable to connect psp to PC - if it works - chances are you have all required wires...

Yes cut out the connector and use the wires inside...and please don't ask which colors... - you need to buy/borrow a multitester to findout which wire connected to which pin.

Can any one check if I did it right? Please?


You switched it up....

Look carefully to the Sheme...
you soldered it wrong... the TxD Contact on the Plug and the GRND !!!!


Look carefully at the scheme and hold your soldered Plug under the diagramm to compere it !!!!
