===How to control fitlet2 front LEDsin Linux?===
==== <ins>For Linux</ins> ====See [[Application note - fitlet2 has 2 controlling front LEDs, LED1 and LED2. Each of them has GREEN and YELLOW parts that can be controlled separately. In on Linux kernel there are 4 related GPIOs: GPIO435, GPIO436, GPIO437, GPIO438.*GPIO435 - LED1 GREEN*GPIO436 - LED1 YELLOW*GPIO437 - LED2 GREEN*GPIO438 - LED2 YELLOW To control the GPIOs need to login as root (root password required): $ su Password: To control for example LED1 GREEN part: $ echo 435 > /sys/class/gpio/export $ echo out > /sys/class/gpio/gpio435/direction $ echo 1 > /sys/class/gpio/gpio435/value # LED1 should be GREEN now $ echo 0 > /sys/class/gpio/gpio435/value # LED1 should be OFF now $ echo 435 > /sys/class/gpio/unexport The GPIO framework and GPIO sysfs interface are documented inhttps://www.kernel.org/doc/Documentation/gpio/gpio.txt]]
