Palm OS Dashboard PRGM
 

Ok, let me begin by saying that i have searched for this, and found only discussion.

Is there anyone out there who has a working dashboard program for palm os?

Thanks

Great Idea. But unless you have a VB compiler for PalmOS, then your out of luck (Like anyone has the time anyway!)

Re: Palm OS Dashboard PRGM
 

not necessarily - a dashboard doesn't have to be written in vb, it just needs to be able to accept serial input, which is perfectly possible for the palm (its sync port is a serial port).

I ment that's all I do.

Re: Palm OS Dashboard PRGM
 

Once we all get familiar with C, there's a neat (read "free") little compiler for the Palm OS called "Pocket C" that might be usefull for writing a dashboard utility.

Re: Palm OS Dashboard PRGM
 

I have a palm program written in C that gets data from the dashboard port then prints it to the screen. It will be a dashboard program eventually I just haven't finished it yet. I will probably finish it after the robot ships.

I'm also working on wiring an LCD to the dashboard port. Right now I have it working with the RC, but it will be more work to actually get it hooked up to the dashboard.

I've done some Palm development before. The actual program coding isn't very hard as the API is pretty straight forward but I have no idea about the serial access. I imagine it would be much harder than coding for the GUI. You might want to search in the developers section of palm.com or on google (you need to sign up, I believe, for palm.com but it is free).

do palms use windows CE? I have eMbedded Visual C++....which develops applications for windows CE...i could pretty easily port a dashboard program i would think, since all this stuff is .NET now....

Palm-based devices use PalmOS. The OS architecture of PalmOS is very different from that of Windows, and a port would probably be more difficult than simply cross-compiling your WinCE code after modifying a few libraries. I have played with Pocket C in the past, and found it to be quite powerful; it might be wise to use the official Palm SDK for more complex operations like serial port I/O, although that necessitates finding a compiler to use with it.

By the way, serial access in Palm, like many other OSes, is actually quite simple. It's just like reading a file in windows. You just call a get function (can't remember the exact syntax right now) and tell it how many bytes you want to get. You can also check how many bytes are in the buffer and many other useful functions.

The hardest part about Palm programming is how anal it is about memory management. If you leak any memory or use a pointer where you should use a handle there is a good chance you will hit a fatal error.

Re: Palm OS Dashboard PRGM
 

Well, I am seriously the 83+SE nerd, so I will attempt to write a program using the get( function... is there any way to get the data from the 9pin to a TI cable? like can someone w/ more electrical knowlege make something that inputs from a 9pin, and then passes each line one by one through the cable? if you could post the schematics for that, it MAY be possible. MAY MAY MAY.

Use one of the older RS-232 TI GraphLink cables with a 9-pin null modem adapter. I don't know if TI still makes them, but if not, there's always eBay.

Being something of a TI fanatic myself, I have to say that your idea is absolutely brilliant. The TI-83's built-in facilities for graphing data would be absolutely superb for monitoring a robot's behavior, and the simple programming interface (in TI-BASIC, anyway) would be ideal for quickly creating a working dashboard program.

Re: Palm OS Dashboard PRGM
 

For those of you interested in programming for PalmOS, there is a free compiler called PRC-Tools (which is based on GCC) which can compile palm programs from C or C++ source. You can get it from http://www.palmos.com/dev/tools/gcc/.

There are IDEs available (such as CodeWarrior for Palm), but none for free yet. However, PalmSource (the makers of PalmOS) have announced that they will release a free IDE (based on Eclipse) for compiling Palm programs at the Developer Conference next week.

Re: Palm OS Dashboard PRGM
 

the question here would be whether the cable actually takes the full input of the serial cable, or is simply using a connector of convinience - the graph link software may only drive a few of the pins on the serial cable in order to drive the few connectors on the other end (in which case the suggested method would not work), or it may have an encoder to encode the value of the serial port into one the calculator port can read (in which case it would work)

you'll have to try and see.

Re: Palm OS Dashboard PRGM
 

Ditto (no se, though). When I first read that, I thought you where NUTS, but then the guy mentioned the gray cable. Detached Solutions can probably give you a few pointers for App dev.

If there is such a device, try CBL/CBR, since there easy functions for that. (big dream)

Tell me how it works (and where I can get a gray cable cheap, the SDK won't use USB, which I have)
