radio_control_ppm module

Radio control based on PPM input

Some STM32 boards have the option to configure RADIO_CONTROL_PPM_PIN. See the board makefile for configure options of the pins. If they set the PPM_CONFIG makefile variable, add it to the target. The PPM_CONFIG define is then used in the board.h file to set the configuration.

Example for airframe file

Add to your firmware section: This example contains all possible configuration options, not all of them are mandatory!

1 <module name="radio_control_ppm">
2  <configure name="RADIO_CONTROL_LED" value="none|num" />
3  <configure name="PPM_CONFIG" value="num" />
4 </module>

Module configuration options

Configure Options

  • name: RADIO_CONTROL_LED value: none|num
    Description: LED number or 'none' to disable
  • name: PPM_CONFIG value: num
    Description: Select PPM config, as some boards can used different mapping for the ppm input pin
