Re: The 8.2 (or 8.3) Battery Voltage Bug
I was just lucky (or unlucky) enough that this bug kicked in while I was bench testing. It seems that the 8.2 battery voltage is really the reading of the p4_wheel. As you move the joystick 4 wheel, the OI battery voltage changes. The p3_wheel is mapped to the backup battery voltage (as shown from the data in the dashboard). the p1_x axis now maps to the joystick #3 switches. I can't say exactly what works and what doesn't as I was just reading what I was sending back from the RC to the OI from the dashboard and didn't really map all the joystick data to the user_bytes/pwm values. A reset doesn't work, but a full power down did (although I know that it doesn't always from previous testing). I do know that one of the joystick ports seemed to be mapped to the "disable" flag (not sure which one), so it's quite likely that the "autonomous" flag was also messed up.

Correction - Rather than the p3_wheel & p4_wheel, it is actually the p3_aux and p4_aux.
