GPIOLibrary

Robot Framework Library for interfacing GPIO pins on executing robot files on Raspberry Pi's.

For Library documentation you can visit; https://yusufcanb.github.io/robotframework-gpio/

Requirements

• Robot Framework (^3.2.2)
• RPi.GPIO (^0.7.0)

Installation

Install RPi.GPIO with command below;

pip install RPi.GPIO

Then install GPIOLibrary with;

pip install robotframework-gpio

Examples

You can find example robot files in the /examples directory.

Basic Usage

*** Settings ***

Documentation   Test LED is fully functional
Library                     GPIOLibrary
Suite Setup                 Begin GPIO Test

*** Variables ***

${LED_PIN}                  17

*** Test Cases ***

LED Should On
    Set Output Pin                  ${LED_PIN}
    Set Pin High                    ${LED_PIN}
    ${pin_status}=                  Get Pin Status      ${LED_PIN}
    Should Be Equal As Integers     ${pin_status}       1

LED Should Off
    Set Output Pin                  ${LED_PIN}
    Set Pin Low                     ${LED_PIN}
    ${pin_status}=                  Get Pin Status      ${LED_PIN}
    Should Be Equal As Integers     ${pin_status}       1

Remote Library Usage

First install robotframework/PythonRemoteServer to Raspberry Pi;

pip install robotremoteserver

Then, start remote library server with following commands;

from robotremoteserver import RobotRemoteServer
from GPIOLibrary import GPIOLibrary

RobotRemoteServer(GPIOLibrary(), host='0.0.0.0')

Finally, you can execute the robot file below from any machine within the same network of Raspberry Pi.
