WebFeb 5, 2024 · A 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 … WebFeb 4, 2024 · timer/counter, this timer/counter will tick upon every four system-clock ticks. ä The period of a timer/counter represents an amount of timer/counter ticks that should occur before the relevant timer/counter overﬂows or underﬂows.

WebA prescaler is essentially a configurable clock-divider circuit. Depending on the selected configuration bits, the prescaler output could be the same as the input signal, or it may have half the frequency, one-fourth the frequency, one-eighth the frequency, etc. Thus, a prescaler can extend a timer’s range by reducing its resolution. WebUpdate Frequency = (TIM_CLOCK / (Prescaler + 1)) / (Period +1) The dividers use an N-1 setting, ie N counts from 0 to N-1. ...
