Jordi came over today and finished up the work on ArduPilot and the second simulator. He caught a lot of bugs that had been bedeviling us, especially unintended crosstalk between the main autopilot processor (the atmega168) and the failsafe processor (the attiny45) that made it impossible to load code when one or the other was on. All fixed now: it was a code error, not a problem with the hardware. The new MUX code is here. The ArduPilot code is still in alpha but we should be able to release it in a few days.
But the important news is that the boards have checked out fine. You know what that means? GREEN LIGHT TO PRODUCTION! The picture above is the final version.

The countdown to commerical release starts now. Stay tuned....

Yes, the code can support any baud rate. You just change the serial speed setting in the setup routine. It's easy to find

Remember this is a DIY autopilot at the moment. You need to get into the code to change settings, such as waypoints, RTL mode.

So in addition to the ArduPilot that's about to release for about $30, the CoPilot and the GPS unit, what else do I need to get to make those changes in the ArduPilot?

Thanks,

I'm still thinking how 2-servo autopilot (throttle and rudder) can technically work, mainly how it will control altitude by throttle with assistance from FMA copilot.
I suppose that FMA copilot just tries to keep plane fly at same level (no rising, no descending). If autopilot wants to change altitude - and I assume it is supposed to do this - won't it fight with FMA which will try to keep the plane fly straight on same level?
Or I'm mistaken, and ArduPilot will just fly on same altitude all time, and only turn left/right to follow waypoints? Actually doing only 2D navigation...

@tycho: all the instructions, including everything you need, are on the ArduPilot home page. Short answer: you need to download the Arduino software

@Michal: No, ArduPilot is a 3D autopilot. Each waypoint has an altitude entry. It does "fight" the FMA co-pilot a bit, but that just means that it crabs and rocks a bit going through the turns.
