What is the use of Pigpio?
pigpio is a Python module for the Raspberry which talks to the pigpio daemon to allow control of the general purpose input outputs (GPIO).
Which module is used to control the GPIO in Python?
Raspberry-gpio-python or RPi. GPIO, is a Python module to control the GPIO interface on the Raspberry Pi. It was developed by Ben Croston and released under an MIT free software license.
What is GPIO module?
GPIO stands for General Purpose Input/Output. It’s a standard interface used to connect microcontrollers to other electronic devices. For example, it can be used with sensors, diodes, displays, and System-on-Chip modules.
How to clean the GPIO pins on a Raspberry Pi?
As mentioned in this article RPi.GPIO basics 3 – How to Exit GPIO programs cleanly, avoid warnings and protect your Pi, correct use of GPIO.cleanup(), Correct use of GPIO.cleanup() RPi.GPIO provides a built-in function GPIO.cleanup() to clean up all the ports you’ve used.
Is there a Python module for GPIO pins?
Before GPIO Zero launched in 2016, new users usually began exploring the GPIO pins with another Python module: RPi.GPIO. RPi.GPIO is only slightly more work to understand, and that effort is worthwhile. Why Not Just Use GPIO Zero for Everything?
How to exit an RPi.gpio program cleanly?
If you want to try it out, it’s a bit long for a live Python session, so you could retype it, or cut and paste it into a program as we did in the first post in this series Now you know how to exit an RPi.GPIO program cleanly, without leaving a trail of uncontrolled ports behind you.
How to clean up GPIO ports with Ctrl + C?
This is the code within the try: block (lines 8-13). The code in the except KeyboardInterrupt: block (lines 15-18) covers the CTRL+C situation. So when you press CTRL+C, it prints the current value of counter, cleans up any GPIO ports you’ve used, and exits.
