A3/N3 runs OSDK MFIO sample code, the pin has no PWM output

Keywords: A3/N3, MFIO function configuration, PWM

It may be that the MFIO parameters are incorrectly configured in DJI assistant 2. MFIO::CHANNEL_0~MFIO::CHANNEL_7 in the code corresponds to SDK 1~8 in DJI assistant 2.

The port set in the sample code is MFIO::CHANNEL_3, so you need to set a physical port in DJI assistant 2 to SDK4 so that you can receive PWM output on this port.
