Hi Guys, this is a work in development.
So far just an extremely accurate clock and directional heading indicator.
The dial works like a compass with the needle pointing North, and degrees from
North printed in small numbers just above the dial.
The dial indicates any of 360 degrees direction, it is basicaly a modification of
the clock example routine that comes with LUA.
I am not certain the speedometer works yet.

It should be good to try and log huge plot and waypoint files in a standard
recogniseable by a PC mapping program.

Anyway, the best thing about it is when there is no position fix EVERYTHING on
the screen is red, and when there is a valid position fix everything on the screen is blue

**Master Inuyasha** · 11-18-2005, 06:23 PM

wait are you saying with this, I know if i am going north or south? Or even how fast i am going, foshizzle my wizzle. <-- That was RETARDED!!!

**Jay C** · 11-18-2005, 06:37 PM

how in the world does this tell which way is north?

**Yeldarb** · 11-18-2005, 06:48 PM

How are you connecting the GPS unit to the PSP?

**Art** · 11-19-2005, 12:54 AM

Yes, a Garmin GPS mouse.
I would post pictures, but there is limited space available for that here.
I got my first map screen going tonight with a crosshair on it to mark
your global position.

The actual map image in this shot is degraded by converting it to gif
format for upload to this forum. I had to fake this image (that is paste
the world map back on it) because while the program is running, the map
and crosshair are never on the screen at exactly the same time, they are
switched so fast that the crosshair appears to be drawn over the map.

Next, I will make the program adjust UTC time for local time automagicaly
because the GPS knows what time zone it is in

I haven't found a way for my program to set the OS clock yet though.

Again, on this screen, I found a graphic way to indicate loss of position fix..
the crosshair dissapears, the map goes very dark, and gets crossed out with a much thicker red cross

Now to work on some more local maps. I was thinking of callibrating
photographic sat maps from Google Earth.

A forum member kindly offered some server space to host this project,
but I haven't been able to connect to it, so if anyone else offers me
a couple of megs hosting, I am happy to share

PS. a GPS knows which direction you are heading by comparing your current
position with previous positions. It only works if you are moving like any GPS.
Cheers, Art.

**Anja** · 11-19-2005, 12:12 PM

hey, tell us more !

**Art** · 11-19-2005, 12:42 PM

Ok, did some work on it in the early hours

used 'X' to toggle between map & information screen earlier...

now implemented circle button to cycle through three options while in the first
screen (posted above, only has Latitude & Longitude display now)
the options are:
1. The first screen you see above with the time feild as the main feild in display
2. a second monochrome screen where the speed in Km/hr is the main feild, and
the small directional heading compass is still displayed
3. a third screen with a large directional heading compass in the middle of the
screen, and no other feilds on the display.

Have found a suitable timezone map to scale down and use in program for
auto time correction mentioned earlier.
Cheers, Art.

**I Bent My Wookie** · 11-19-2005, 03:34 PM

im guessing this wont require wi-fi, but just to make sure: Do I need wifi??

OT: 400th Post!!

**Art** · 11-19-2005, 04:06 PM

Nup. It uses the headphone connector, because there is a serial connector next
to it. You need to biuld a small circuit to get the PSP serial port to work with anything.

I have a schematic for this circuit ready and it works, but I might update it for
two way communication yet. This would allow the PSP to configure the GPS mouse
by itself, instead of having to connect it to a PC first. The GPS mouse needs to output
some sentences that are standard, but not enabled by default.

You can get images hosted at imageshack.us. I think this is cool but a lot more people would believe you if you posted pics of it on your pspscreen and the gps.

**Master Inuyasha** · 11-19-2005, 04:52 PM

Oh I thought you had referred that as a compass. Sorry for not actually thinking, or reading this word "GPS", and I would've known it wasn't a compass. Cool, have fun!!! LOL

**Art** · 11-19-2005, 05:51 PM

I have those sort of photos, but they are too big to be hosted on the forum.
After zipping the whole package it's only 1.65 MB, comparable to some of the
programs in the files section.
I will try to have the whole package hosted here.

Well I believe him. Have you seen the luaplayer forum? He has about 3 topics about the IO function and integration.

Even a single photo taken with my digital camera is too large.
When I can use my desktop again i will submit the package to this

Wow. Just wow.

Looks like you got some 'documentation' on how to put it together, awesome.
Of course, I can't make one of those.. too complicated. And even if I did, I would be too scared to try it on my PSP.

And, uh, whats with that little guy picture? blockimageArt

**Art** · 11-19-2005, 09:11 PM

Ah yeah, that is a serverely reduced size image of me that I was going to blit
across a map screen. it isn't actualy used in the program.
I didn't think the circuit was much more involved than the standard serial circuit
you need for the LUA serial terminal.
Anyone who used to chip the first playstations would be able to program a 16F628
because it's in the same family as the pic 12C508/509 that was used for Playstation
modchips.

I can't make them and sell them because the PSP headphone connectors are not
available.

I am going top get a second PSP, so I will still have one working remote controller.
Art.

**thedan** · 11-20-2005, 03:00 AM

I honestly dont know the correlation between aussies and hardcore modding, but wow. If you can make your PSP a GPS for cheap, that would be sweet and make geocaching really cool =)

**thedan** · 11-20-2005, 03:14 AM

oh, and here's Art's work instead of rapidshare:

**Art** · 11-20-2005, 01:22 PM

Thanx for the comments, and for hosting it Admin

problem is it won't be long at all before it is outdated by newer work

I took it for it's first test drive last night and it works great.
Despite it's functionality, this is still a very poor example of how to program.
I'm having trouble picking up LUA syntax being used to either assembler or BASIC.
Because of this, I'm settling for poor programming style that works.
I only just learned to access an array, and now need to find out how to write a plot
/track file from within LUA.

When it comes to moving maps, I think with LUA, I will have to try to do the graphics
in tiles just like a game.. since the maps are photograhs.

Just a note..
I will offer personal to support anyone who makes this modification as I am keen to
have a tester of new sw, but if you are new to electronics, I would suggest holding
off until it is determined that the hardware circuit design is finished (or required at all).
Cheers, Art.

**Clay** · 11-20-2005, 03:39 PM

Awesome work Art! I've posted this on the front page, please let me know if there is anything you would want me to add / change about the article.

Intriguing thread. Less chatter, more work.
Garmin, you say? Hmmm...anyway to get it to use MGRS on the PSP instead of Lat/Long? That's "Military Grid Reference System" and what NATO and the U.S. military uses. My old Garmin could do MGRS and I loved it. Did more "tricks" than our PLGRS (called "pluggers") could and it's what we used in the desert more than the PLGRS.

Art.

Are you talking about this ? (may be a little cheaper than a new PSP)

You may also want to talk to the guys at team xecuter, they may be willing to help make the GPS unit.
