Raspy UAV
Raspy UAV is a quad-copter based on Raspberry board, Navio operating system and performing RC data acquisition thanks to a specific Microchip PIC18 series uC which I have programmed and Adafruit 16-Channel 12-bit PWM/Servo Driver. Communication between Raspberry and RC data acquisition board is based on I2C protocol where the Raspberry acts as master and the uC as slave. I was able to extend Ardupilot code so that data acquisition occurs periodically at a rate high enough to guarantee safe control of the aircraft.
