From TIM to ADC

As shown in Figure 3, some timers can be used to generate an ADC trigger event.

The ADC synchronization is described in the conversion on external trigger and trigger

polarity section of RM0385 reference manual.

For more details on the connection between timers and ADCs regular and injected

channels, refer to external trigger for regular channels table and external trigger for injected

channels table of RM0385 reference manual.

The output (from timer) is on TIMx_TRGO or TIM_CHx signal event.

The input (to ADC) is on EXTSEL [3:0], JEXTSEL [3:0] signal event.

2.1.3

From TIM to DAC

Some timers can be used as triggering an event to start a DAC conversion (see Figure 4).

The selection on input triggers in DAC is provided in the DAC trigger selection section of

RM0385 reference manual.

The output (from timer) is on TIM_TRGO signal directly connected to the corresponding

DAC inputs.
