RIOT/tests/periph/gpio_arduino

Arduino peripheral GPIO Test

This test is designed for testing the Arduino to RIOT pin mapping on boards with Arduino support. It is much like tests/periph/gpio but for Arduino pin numbers.

In this test, pins are specified by integer pin numbers. It uses a single integer to indicate the arduino digital pin.

At this point the Analog pins are not supported.

Commands

init_out <pin>

init as output (push-pull mode)

init_in <pin>

init as input w/o pull resistor

init_in_pu <pin>

init as input with pull-up

read <pin>

read pin status

set <pin>

set pin to HIGH

clear <pin>

set pin to LOW

toggle <pin>

toggle pin

Example

Blink the Arduino UNO led once.
