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. WebThe frequency of your timer interrupt will be equal to the following: $$ \frac{\mbox{microcontroller clock frequency} }{(\mbox{prescaler}) \times (\mbox{compare match register value} + 1)} $$ So, since you mentioned that you're using an Arduino which comes with a 16 MHz crystal, to achieve an interrupt frequency of 24 Hz the value of the …
