7 Assignment 5: Event System (EVSYS) Used to Replace the RTC Interrupt Handler
In this assignment, the event system with the RTC overflow event signal, instead of the RTC overflow interrupt, will be used to trigger an ADC conversion.
7.2 Event System Driver Code Development

7.2 Event System Driver Code Development

Todo: Clean up driver_isr.c with removal of the RTC interrupt routine.

Once the event system configuration has been updated in Atmel | START, the application code needs to be updated in Atmel Studio.

Remove the RTC interrupt routine in driver_isr.c as its function has been realized by the event system. The driver_isr.c file should look like:
Figure 7-5. Assign5_driver_isr.c_view

Info: Since the RTC interrupt routine has been removed, the device will be kept in Standby Sleep mode while the event system with the RTC overflow event source triggers to start the ADC conversion.
Program the device by clicking Debug → Start without Debugging on the top menu window or by using the Ctrl+Alt+F5 shortcut.
Info: Start Without Debugging will build the project and program the device as long as there are no build errors.
