PWM measurement.
|
|
|
|
PWM input measurement mcu periph access and init wrapper for other modules.
|
|
|
|
For LPC21xx on the TWOG:
|
|
- INPUT CAPTURE CAP0.3 on P0.29 (TWOG ADC5, 5V to 3.3V voltage divider)
|
|
- INPUT CAPTURE CAP0.0 on P0.30 (TWOG ADC4, no voltage divider)
|
|
|
|
For STM32:
|
|
- each board (or airframe file) has to define the PWM input pin and parameters
|
|
- example can be found in sw/airborne/boards/apogee_1.0.h board file
