====== Basics of 12pin Port ====== The **ODROID-XU4** provides 12Pin GPIOs. {{http://dn.odroid.com/wiki_image/xu4/xu4_con11.jpg}} **Easy to use GPIOs**\\ First, you refer to below link.\\ You check Export number that you want to use GPIO.\\ [[en:xu4_hardware_gpio | Pin description]] Create a GPIO file access.\\ You can access GPIOs using sysfs interface. echo 34 > /sys/class/gpio/export Configure the pin direction (in/out) echo in > /sys/class/gpio/gpio34/direction Read a value cat /sys/class/gpio/gpio34/value
