10.3.3 From ADC to timer (TIM1/TIM8)
Purpose
ADC1 can provide trigger event through watchdog signals to advanced-control timers
(TIM1/TIM8).
A description of the ADC analog watchdog setting is provided in:
window watchdog (AWD1EN, JAWD1EN, AWD1SGL, AWD1CH, AWD2CH, AWD3CH,
AWD_HTx, AWD_LTx,
Trigger settings on the timer are provided in:
Triggering signals
The output (from ADC) is on signals ADCn_AWDx_OUT n = 1, 2 (for ADC1, 2) x = 1, 2, 3 (3
watchdog per ADC) and the input (to timer) on signal TIMx_ETR (external trigger).
Active power mode
Run, Sleep, Low-power run, Low-power sleep.
10.3.4 From timer (TIM2/TIM4/TIM5/TIM6/TIM7/TIM8) and EXTI to DAC
(DAC1/DAC2)
Purpose
General-purpose timers (TIM2/TIM4/TIM5), basic timers (TIM6, TIM7), advanced-control
timers (TIM8) and EXTI can be used as triggering event to start a DAC conversion.
Triggering signals
The output (from timer) is on signal TIMx_TRGO directly connected to corresponding DAC
inputs.
Selection of input triggers on DAC is provided in
(single and dual mode).
Active power mode
Run, Sleep, Low-power run, Low-power sleep.
10.3.5 From timer (TIM1/TIM3/TIM4/TIM6/TIM7/TIM8/TIM16/LPTIM1/LPTIM2)
and EXTI to DFSDM1
Purpose
General-purpose timers (TIM3/TIM4), basic timers (TIM6/TIM7), advanced-control timers
(TIM1/TIM8), general-purpose timer (TIM16), low power timers (LPTIM1/LPTIM2) and EXTI
can be used to generate a triggering event on DFSDM1 module (on each possible data
block DFSDM1_FLT0/DFSDM1_FLT1/DFSDM1_FLT2/DFSDM1_FLT3) and start an ADC
conversion.
DFSDM triggered conversion feature is described in:
conversions.
