Re: Run Jaguar's through PC

do you know where i can get the documentation on how the data is sent to the Jag by RS232, i need to know things like how the data is organized. for example, in the LabVIEW code there is a input into the "FRC_Communication" that is the data size, is that sent over or is is used just for that program. If I can get that information I just might get that old wheelchair running autonomously

Re: Run Jaguar's through PC

I wish I had much to add, but my guess would be to somehow reverse engineer the serial can structure in the FRC code.

either that, or PWM it. PWM control with boe bots was easy, (driving PWM wheel servos) as all you did was send pulse rates to a digital output (in hz IIRC), ranging from 6500 (full reverse) to 8500 (full forward), with 7500 being neutral (stop).

In fact, IIRC, the original IFI controllers used the same BASIC STAMP controller as boe bots...

for that matter, if you knew C (like I will after the next few months), you could obtain a second hand later generation IFI controller and drive them that way.

Re: Run Jaguar's through PC

From my previous work with networking, the easiest way for me would just be just to use wireshark and reverse engineer the packets being sent. Since CAN is just networking it should be pretty simple. The only thing I could for-see holding you back would be the packets being encrypted.

Try looking at the source to the black jag bridge plugin like I originally suggested.

http://firstforge.wpi.edu/integratio...ystem=exsy1002

It implements the serial protocol you need.
