Synopsis

./gpio <pin> <command> <target> [input]

Where:

* <pin>: (pin formatted as "p8_16")
* <command>: "read" or "write"
* <target>: "value" or "direction"
* <input>: (used only with write commands)

Usage:

# Example: set pin p9_12 as output and and turn it on
./gpio p9_12 write direction out
./gpio p9_12 write value 1

# Example: set pin p8_16 as input with internal pull-up resistor and read its value
./gpio p8_16 write direction in+
./gpio p8_16 read value
