Enhancement of 40pin GPIO

The ODROID-C1/ODROID-C1+ provides 40Pin GPIOs.

Easy to use GPIOs
First, you refer to below link.
You check Export number that you want to use GPIO.
Pin description

You need to enter into super-user mode first to run below commands !!

 sudo su 

Create a GPIO file access.
You can access GPIOs using sysfs interface. This example uses pin number 18 which is connected to the GPIO102(GPIOX.BIT5).

echo 102 > /sys/class/gpio/export

Configure the pin direction for input

echo in > /sys/class/gpio/gpio102/direction

Configure the pin direction for output

echo out > /sys/class/gpio/gpio102/direction

Read a value (if gpio direction is input)

cat /sys/class/gpio/gpio102/value

Write a value (if gpio direction is output)

echo 1 > /sys/class/gpio/gpio102/value : gpio high
echo 0 > /sys/class/gpio/gpio102/value : gpio low
