Clock source prescaler
WebA prescaler dictates the speed of your timer according the the following equation: (timer speed (Hz)) = (Arduino clock speed (16MHz)) / prescaler So a 1 prescaler will increment the counter at 16MHz, an 8 prescaler will increment it at 2MHz, a 64 prescaler = 250kHz, and so on. As indicated in the tables above, the prescaler can equal 1, 8, 64 ... WebFeb 3, 2016 · This article shows you how to correctly set up the clock source, prescaler and ARR to get regular events over a wide range of frequencies. This is the second in a series of articles on using the general purpose timer, TIM3, available on all the STM32 family processors.
