- Description:
- The STM32 ADC can be configured to use external trigger sources
- (e.g. timers, pwm or exti gpio). Then, it can be tuned to start
- conversions on external trigger by either:
- - "rising-edge"
- - "falling-edge"
- - "both-edges".
- Reading returns current trigger polarity.
- Writing value before enabling conversions sets trigger polarity.
