In this assignment, the ADC result ready interrupt will be replaced by the ADC WCMP interrupt, to trigger a USART transmission. In this case, the ADC result, which is below ADC window threshold value, will trigger USART transmission. The ADC results, which are above the window threshold value, will be ignored and not trigger any USART transmission.
Atmel | START will be used to reconfigure the ADC module, and the Atmel Studio project will be updated with the new configuration.
