ADC:
STM32F103RBT6 have two 12-bit Analog to Digital Converters which share up to 16
external channels, performing conversions in singleshot or scan modes. In scan mode,
automatic conversion is performed on a selected group of analog inputs.
Additional logic functions embedded in the ADC interface allow:
- Simultaneous sample and hold
- Interleaved sample and hold
- Single shunt
The ADC can be served by the DMA controller.
An analog watchdog feature allows very precise monitoring of the converted voltage of one,
some or all selected channels. An interrupt is generated when the converted voltage is
outside the programmed thresholds. The events generated by the standard timers (TIMx) and
the Advanced Control timer (TIM1) can be internally connected to the ADC start trigger,
injection trigger, and DMA trigger respectively, to allow the application to synchronize A/D
conversion and timers.
