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

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

${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.
