Dell Edge Gateway 3001 Installation and Operation Manual

The GPIO connector (AD5593R) on the Edge Gateway 3001 has 8 pins. The connector can controlled by the standard Linux GPIO.The GPIOs number maps 330 to 337.

Example 1 (as root): Set GPIO 1 as output, value as 1

$ echo 330 > /sys/class/gpio/export
$ echo out > /sys/class/gpio/gpio330/direction
$ echo 1 > /sys/class/gpio/gpio330/value

Example 2 (as root): Set GPIO 8 as input, and read value

$ echo 337 > /sys/class/gpio/export
$ echo out > /sys/class/gpio/gpio337/direction
$ cat /sys/class/gpio/gpio337/value
0

Example 3 (as root): Connect GPIO 1 to 8, read GPIO 8 pin value

$ cat /sys/class/gpio/gpio337/value
1
