# 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.
