Examples on how to use on board LED using mraa library

Following examples are provided to use LED using MRAA library.

1. mraa_led.c
2. mraa_led.cpp
3. mraa_led.py

Usage:

Prerequisite: Debian running on 96Boards CE with libmraa installed

• Copy the examples to 96Boards CE
• Build the C/C++ examples:

$ gcc mraa_led.c -o led_c
$ g++ mraa_led.cpp -o led_c++

• Execute the examples:

$ sudo ./led_c
$ sudo ./led_c++
$ sudo python mraa_led.py

Expected Behaviour:

1. Reads maximum brightness value for USER1 led and turns it ON/OFF depending on current state.
2. Finally sets led trigger to heartbeat.
