WebMar 31, 2024 · The problem & solution. For a time based interrupt using the internal clock of a timer finding the right PSC and ARR values for a given interrupt interval (or frequency) can be quite difficult. Since EVENT_FREQUENCY = TIM_CLK / ( (PSC+1) * (ARR+1) ) finding the correct PSC and ARR values for a given EVENT_FREQUENCY is solving the equation:

WebSTM32 Timers In Encoder Mode. The two inputs TI1 and TI2 are used to interface to an incremental encoder. The counter is clocked by each valid transition on TI1FP1 or TI2FP2 (TI1 and TI2 after input filter and polarity selection). The sequence of transitions of the two inputs is evaluated and generates count pulses as well as the direction ...
