Suppose you have a 16-bit timer with a 16 MHz clock and a 100 prescaler value configured in periodic mode. An interrupt service routine has been written that queues an ADC conversion on interrupt. If you want to sample the analog value at a frequency of 1kHz, what load value should be used?

Answer rating: 100% (QA)

First calculate the prescaled clock frequency prescaled clock frequency 16MHz 100 160kHz Then divide the desired interrupt frequency by the prescaled clock frequency to get the timer reload value time... View the full answer
