I have a quadcopter with PX4FMU (without PX4IO) on it and i use AC 3.0.1 on it because AC 3.1 and later dos not support FMU only board (4 Motor PWM outputs on UART2 pins are disabled).
Is there any way to add PWM output on arducopter 3.1 or 3.2 rc4 again? AC 3.0.1 don't have some required features like GPS Glitch protection.
i am familiar to C++ language and it maybe i can add it again if i know where is write motors class/function and PWM driver.
I want to use PX4FMU + Odroid for vision navigation in my theses.
