SDCC for Vex is here!

[outpaddling]

Hello everyone,

Thanks to a 2-man programming marathon over the holiday break, it's now possible to program Vex robots using SDCC.

In case you didn't already know, SDCC is a free, open source compiler for microcontrollers, which runs on virtually any operating system and hardware, including PowerPC Macs.

We have developed a new version of LibVexBot that builds under both MCC18 v3.x and SDCC v2.7.0 or later. Most of the development was done using SDCC 2.8.0, but I also built and uploaded the code from an iBook G3 running SDCC 2.7.0, and didn't see any problems.

All the details can be found at:

Many thanks to Ag Primatic, who did most of the work on the SPI interface and also helped clear several other hurdles.

Happy hacking,

Jason

Hello,
I recently stumbled upon Open Vex and think it is a very solid implementation on the Pic controllers (hoping for Cortex support but w/e).

Anyway I was wondering if the only working repo is the one at http://personalpages.tds.net/~jwbacon/Ports/distfiles/ or if there is a public repo where one can commit changes (like a git.) If not I'd be happy to maintain it

P.S. Does anyone know how to detect competition start signals and what not. I figure its just a serial call however if there is a working method no need to reinvent the wheel
