I'm trying to write an on-drone app with PID control to AR.Drone with the GPS data.
I figured out how to make a serial port from regular DIO pins that is totally driven by interrupts, unlike the 'softserial' from the Arduino folks. It uses timer0 to do the timing and at this point can go from 110 to 115200 baud. This means we could pass on the data to the drone program 'GP*<whatitis>=....' and have it interpreted there?
Still worried about the power....
