pigpioread - Show Raspberry Pi GPIO pin status, configuration and functions
« on: May 10, 2025, 01:19:46 am »
Wasting time over and over again to find possible Pi pin configurations - like which pins support I2C, PWM, or other functions? Save time with this handy tool:

https://github.com/zeljkoavramovic/pigpioread

It simplifies pin configuration lookups, making your projects faster and easier!  ;)

EDIT: More accurate wording, thanks to Thaddy and ccrause

How can you struggle to find data sheets for the Raspberry Pi? They are on the website. For every one of them.
Start here:
https://www.raspberrypi.com/documentation/computers/raspberry-pi.html

Now, how can that cause struggling? >:D

Not mentioned here by avra, but a useful feature is inspecting the current state of pins.

This tool also reminds me of Norton Guides that enabled one to call up technical reference material with a few keystrokes (this was of course before internet).

Well the pins are the same (except now there are more), but the entry addresses differ. But there are only two versions.

You are quite right. My wording choice was not good. Hopefully fixed that now. Thanks!

Somehow I completely missed to mention it even on github. Fixed that now. Thanks!
