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.
