Raspberry Pi GPIO Emulator

This Raspberry Pi emulator simulates some of the functions used in the RPi.GPIO library (using python). The intention of this library is educational.

Installation

The easiest way is to download the zip file and extract the files in the same working environment of your script. To use the emulator just type the following at the beginning of your script.

from EmulatorGUI import GPIO

Simulation

This library simulates the following functions which are used in the RPi.GPIO library.

• GPIO.setmode()
• GPIO.setwarnings()
• GPIO.setup()
• GPIO.input()
• GPIO.output()

Test Example

from EmulatorGUI import GPIO
#import RPi.GPIO as GPIO
import time
import traceback

def Main():
    try:
        GPIO.setmode(GPIO.BCM)

        GPIO.setwarnings(False)

        GPIO.setup(4, GPIO.OUT)
        GPIO.setup(17, GPIO.OUT, initial = GPIO.LOW)
        GPIO.setup(18, GPIO.OUT, initial = GPIO.LOW)
        GPIO.setup(21, GPIO.OUT, initial = GPIO.LOW)
        GPIO.setup(23, GPIO.IN, pull_up_down = GPIO.PUD_UP)
        GPIO.setup(15, GPIO.IN, pull_up_down = GPIO.PUD_DOWN)
        GPIO.setup(24, GPIO.IN, pull_up_down = GPIO.PUD_DOWN)
        GPIO.setup(26, GPIO.IN)

        while(True):
            if (GPIO.input(23) == False):
                GPIO.output(4,GPIO.HIGH)
                GPIO.output(17,GPIO.HIGH)
                time.sleep(1)

            if (GPIO.input(15) == True):
                GPIO.output(18,GPIO.HIGH)
                GPIO.output(21,GPIO.HIGH)
                time.sleep(1)

            if (GPIO.input(24) == True):
                GPIO.output(18,GPIO.LOW)
                GPIO.output(21,GPIO.LOW)
                time.sleep(1)

            if (GPIO.input(26) == True):
                GPIO.output(4,GPIO.LOW)
                GPIO.output(17,GPIO.LOW)
                time.sleep(1)

    except Exception as ex:
        traceback.print_exc()
    finally:
        GPIO.cleanup() #this ensures a clean exit
