WebSep 6, 2024 · Configuring the timer peripheral only needs to be done once, in the initialization part of the code and before the infinite loop. In this part you set the time for each increment of the counter (1us, 0.1ms, etc.) and also the value the counter needs to reach for interrupt to be generated. WebTimer Overview. Typically most STM32 timers consist of a 16-bit auto reload counter and a 16-bit prescaler. The prescaler is responsible for dividing the incoming clock signal from a clock source as per our need. The auto-reload counter is loaded just we used to load timer registers of 8-bit MCUs. fleet management software busWebSo I was beginning with general-purpose timers and I am stuck with prescale and period values.
