Arduino Timer Interrupts Tutorial & Examples
August 17, 2023 - For example, Timer1 in Arduino UNO is clocked at 16MHz. With a prescaler of 1:1, the Maximum TOUT can be achieved by setting the TicksCount to its maximum value of 65536. This will give us TOUT(Max) = (1×65536)/16M = 4.1ms.

April 25, 2013ESP32 timer interrupt handler and Yield
(For those who are coming, even if it's reviving a 2 yo topic...) "Yield" is in freeRTOS context, it means force the scheduler to check if another task of higher priority is ready to be continued. You should yield if you triggered an event (push to queue, give to semaphore, notify, or set bit in event) from the ISR. If you didn't, then you spare some ticks. Normally, triggering the event also triggers the scheduler. But since ISR should be handled fast, this check is not done in the *fromISR() functions, hence the need to inform FreeRTOS if it should or not. More on reddit.com

February 19, 2018 - To help make timing longer events easier (especially when some of the timers can only count up to 255), a prescaler can be used. A prescaler, in effect, divides the system clock to make something operate more slowly. For example, here is Timer1 counting up to 15 with no prescaler.

January 28, 2025 - So the counter counts down and triggers the interrupt at 0. ... The value to be passed to timer1_write(), “Timerpreload“, results from the system clock, the prescaler “presc” and the desired frequency “fdesired” or the desired period “perioddesired” : If you want it to be easier, you should use the Ticker library. You don’t have to install it because it is part of the Arduino ESP8266 package. I think the example is self-explanatory:
