We plan, we fail, and move along

No excuses. Last minute changes caused last minute problems that we were unable to overcome. Although we were at the race, the vehicle’s GPS was flakey and being knocked out continuously even in open sky. The problem was discovered on Wednesday before the race. Lack of time failed to get it resolved before we arrived and I pulled the plug much to Floyd’s chagrin, I’m sure.

SparkFun posted a race recap. Maybe next time. From the stats, it appears were were not the only team with an issue or three. Maybe next year.

Traxxas Now with More Horsepower

April 9, 2010 Leave a comment

Okay, perhaps the title is a bit misleading…more computational horsepower. Today, I finally got around to mounting the TS-7800 from Technologic Systems. It’ll be running all the main processing and communicating with the micro controller via a serial port.

Additionally, we’d failed to include a shiny “GO” switch anywhere in the system so I used the DIO port on the ARM to read in a signal to indicate the mission should execute. If you are looking for sample code for the TS-7800, Eric Robishaw’s example is a good start.

If that’s a little much to parse, here’s my simpler variant. It does far less but is a test bit of code that shows the reading without a lot of extra capability.

I’ll leave you now to get back to porting code over to the board. Here’s the vehicle with its ever growing payload.

Computational Horsepower for Easy Living

Update: Just a word of warning, the distribution of Debian shipped with these board is ANCIENT. Packages are no longer available.

Vehicle Overview and Near Destruction

Just for fun

And some near destruction before proper handling of GPS popping was in place…

Apparently my code has a preconceived need to heard toward fences. Don’t ask me why….
