# Button HAL Example
This example demonstrates and tests the functionality of the Button HAL.
You can use this example to:
* Understand the logic of the button HAL.
* Test your implementation of arch-specific button HAL components if you are
developing a new port.
This example assumes a device with at least one switch (button or simiar).
# Supported devices
This example is expected to work off-the-shelf on the following boards:
* All CC13xx/CC26xx devices
* All CC2538 devices
