my plan is to take the readings from the pots in the rc gimbals
but i dont know how to simulate that signal and send it back out to the rest of the rc system ready for transmition,
can anyone give me a pointer?
void* p = NULL;
The pots just have analog levels at the wipers, yes? Connect those to two analog inputs.Read them in, send out as digital values, or mimic them with DACs elsewhere if you need analog again.
Or simply include appropriate digital potentiometers in your device. Use A2D to determine the limits your interested in, then "swap" in a digital pot and perform your tests with the digital pot replacing the signals from the controllers pot.
