Overview

The sample initializes and blinks LED0 on the device.

User interface

LED 0:

Lit when the device is initialized.

LED 2:

Blinky LED.

Building and running

This sample can be found under samples/peripherals/leds/ in the Bare Metal folder structure.

For details on how to create, configure, and program a sample, see Getting Started with the samples.

Testing

You can test this sample by performing the following steps:

1. Compile and program the application.

2. Observe that the LEDs sample initialized message is printed.

3. Observe that LED0 is blinking.
