Overview
This is the 2/3 chapter of IGEP COM PROTON Tutorial Guide.
We will learn some basic tasks.
What can I do
You must logged in the board.
Handle the gpio-LED's
The board has three leds available that can be controlled. In its simplest form, you can control of LEDs from userspace. LEDs appear in /sys/class/leds/ and you can turn on and off with following commands:
echo 1 > /sys/devices/platform/leds-gpio/leds/d242\:green/brightness echo 1 > /sys/devices/platform/leds-gpio/leds/d441\:green/brightness echo 1 > /sys/devices/platform/leds-gpio/leds/d442\:green/brightness
A detailed guide on how use GPIO-LEDS can be found by following this link: How to handle the gpio-LED
