The GPIOTE Example shows how to use the GPIOTE peripheral by toggling a LED.
The application starts with configuring the GPIOTE output pin to toggle on a GPIOTE task. Timer 0 is then configured to generate events every 200 milliseconds. The events are passed through the PPI peripheral to generate tasks, which are then used by GPIOTE (in task mode) to toggle the GPIO pin. This means that every time there is an EVENT_COMPARE event, the GPIO pin toggles automatically, which can only be achieved using the GPIOTE peripheral.
The task flow is as follows:
[TIMER0]->EVENT_COMPARE->[PPI]->GPIOTE_TASK_OUT->[GPIOTE]->toggle_pin
