RPi.GPIO Documentation and Tutorials

Here you’ll find an index of links to all the RasPi.TV RPi.GPIO tutorials.

RPi.GPIO Basics series

1. How to check what RPi.GPIO version you have
2. How to check what Raspberry Pi board Revision you have
3. Finding Out Info about the Raspberry Pi you are using (RPi.GPIO 0.5.10 or higher)
4. How to Exit GPIO programs cleanly, avoid warnings and protect your Pi
5. Setting up RPi.GPIO, numbering systems and inputs
6. Setting up and using outputs with RPi.GPIO
7. Using inputs and outputs at the same time with RPi.GPIO, and pull-ups/pull-downs
8. RPi.GPIO cheat sheet

RPi.GPIO more advanced

Interrupts (needs RPi.GPIO 0.5.2+)

• Background and simple interrupt: How to use interrupts with Python on the Raspberry Pi and RPi.GPIO
• Threaded callback: How to use interrupts with Python on the Raspberry Pi and RPi.GPIO – part 2
• Multiple threaded callback: How to use interrupts with Python on the Raspberry Pi and RPi.GPIO – part 3
• Edge Detection: Detecting both rising and falling edges with RPi.GPIO
• Port setup Function checking
• GPIO mode checking with GPIO.getmode()

Software PWM

From 0.5.2a onwards, RPi.GPIO has software PWM. Below are two links. One describes its basic usage and the other is a practical application for dimming LEDs and controlling motor speed.

• PWM: RPi.GPIO 0.5.2a now has software PWM – How to use it
• PWM practical: How to use soft PWM in RPi.GPIO 0.5.2a pt 2 – led dimming and motor speed control
