In the video I set to 499, it means that the counter will count from 0 to 499 with 1ms cycle, so totally the interrupt time will be 500*1ms =500ms. Counter period: the value that the counter will count to or count from (depend on count-up or count-down).For count-down: the counter will count from the value stored in Auto-reload register (Counter period) down to 0 and then generate Underflow interrupt and start all over again from stored value. For count-up: the counter will count from 0 to the value stored in Auto-reload register (Counter period) and then generate Overflow interrupt and start all over again from 0. Make sure that you can compile an existing cube project for your chip 2) make sure that you can set up and compile a cube project for your chip. Counter mode: can be count-up or count-down.We will use the input capture to measure the Frequency and width of the input signal. which can be used as trigger input by the slave. Input Capture in STM32 This is yet another tutorial in the Timer Series in STM32, and today we will see how to use Input Capture in STM32.

In the video I set to 47999 (not 48000) so it means that the frequency supply for the counter will be equal to 48MHz/(47999+1) = 1000Hz = 1ms. The input stage samples the corresponding TIx input to generate a filtered signal TIxF. Prescaler: can be understood as a frequency divider for the counter, with range from 0 to 65535. Learn STM32 Timers, CAN, RTC, PWM, Low Power embedded systems and program them using STM32 Device HAL APIs step by step.There are some definitions that need to be mentioned here: Noticed the configurations that I have entered in the timer setting window of TIM3. The HAL driver layer implements run-time failure detection by checking the input values of all functions. For example, the timer APIs are split into several categories following the IP functions, such as basic timer, capture and pulse width modulation (PWM). Void HAL_TIM_IC_CaptureCallback(TIM_HandleTypeDef *htim) The HAL drivers are feature-oriented instead of IP-oriented.
