I tried some configurations but nothing worked - no interrupt on timer3 when I set the output trigger (timer I believe that the capture interrupt mechanism would work in encoder mode, so setting TIM1->DIER |= TIM_DIER_CC1IE should generate an interrupt every time the counter is changing. Trgo2 event can be used as trigger event of ADC, and single event or combined event can be selected. The falling edge of this channel is the trigger for timer B to create the phase shift.

with Creative Commons CC-BY-SA In STM32, UART is the most common mode of communication - it receives one byte at a time, and we can use polling, but for some data In order to solve the above problems, the most commonly used method on the Internet is to use idle interrupt, that is, when the serial port is idle, trigger an interrupt. 19 TIMx and external trigger synchronization of the In this mode, the timer shall count to the maximum level (set by the ARR), the following will happen: Assigns the corresponding output pin to a programmable value defined by the output compare mode. Since the time the ADC performs a conversion of the ADC clock CLKADC and the sampling hold time is accurately determined, this method is effective to reduce the aperture.
In PWM input mode, the timer is able to capture both the period and the duty cycle of an incoming PWM signal.
* Trigger event: counter starts, stops, initializes or has internal/external trigger count * Input Capture * Output comparison.
Subsequently, the sampling frequency can be controlled by changing PWM frequency (i. An STM32 timer module can operate in any of the following modes, however, you should not assume that a given timer does support all of these modes. Set timer A channel 2, 3 or 4 as your output 1.
