You should develop a driver that will handle an interruption when your
button is pressed. A simple stream driver should do it perfectly.

In your IST, you can implement 2 things:

- either direclty switching on and off the led through registers accesses.
- or using GWES API for led notification, and develop a notification led
driver.

The second solution is the cleanest, as it allows you driving your leds from
other apps or drivers through the GWES API.
