I'm doing a project related to telemetry, and I want to make ArduPilot (programmed with ArduPlane 2.73) send through a serial port the sensors informations such as height, GPS position, etc.. I have tried to use ArduStation, but I could not change its firmware to do what I want.
The idea would be to read the Ardupilot's serial port using an Arduino Uno, and then saving it in a SD card in real-time. So ArduPilot needs to send data without any user input or something like that. I've already tried to manipulate ArduPlane source code to do that, but I couldn't either.
Has someone here did something like that before? I need some advice!
