I wonder what are the options of taking still images in the AirPi? Can’t find the info on wiki.
I want to take an image by toggling keys on my radio say on a dedicated channel which will be received by the radion RX and then either send to one of the GPIOs directly or via Pixhawk. In anyway this will be a PWM signal. There are dedicated PWM ports on the pi which can process PWM signal.
So what options do I have?
