actuators_ppm module

Actuators Driver using PPM output

This is used in the case where you want to directly drive a receiver which has a microcontroller to do the decoding and driving of the servos (not a 4015 or 4017 decoder chip). The PPM is output on the SERV_CLK pin. The PPM frame rate, pulse width, and number of channels Can be adjusted in the "servos_ppm_hw.h" file to suit your particular receiver.

Example for airframe file

Add to your firmware section:

<module name="actuators_ppm"/>
