Python library for the Pimoroni 5x5 RGB Matrix Breakout

LED Matrix

https://shop.pimoroni.com/products/5x5-rgb-matrix-breakout

An adorably tiny 5x5 pixel Breakout Garden compatible LED matrix breakout for adding status displays or fancy lighting to your project.

Installing

Full install (recommended):

We've created an easy installation script that will install all pre-requisites and get your LED Matrix up and running with minimal efforts. To run it, fire up Terminal which you'll find in Menu -> Accessories -> Terminal on your Raspberry Pi desktop, as illustrated below:

In the new terminal window type the command exactly as it appears below (check for typos) and follow the on-screen instructions:

curl https://get.pimoroni.com/rgbmatrix5x5 | bash

Manual install:

Library install for Python 3:

sudo pip3 install rgbmatrix5x5

Library install for Python 2:

sudo pip2 install rgbmatrix5x5

Development:

If you want to contribute, or like living on the edge of your seat by having the latest code, you should clone this repository, cd to the library directory, and run:

sudo python3 setup.py install

(or sudo python setup.py install whichever your primary Python environment may be)

In all cases you will have to enable the i2c bus.

rgbmatrix5x5-python's Issues

setting up two 5x5 RGB's

Your example code for doublerainbow.py is adressing 0x74 and 0x77 on i2c, but only the 0x74 is working on my two 5x5 RGBs. How do I setup one of the two matrixes to use the 0x77, I see reference to a "cut trace" in the product desciption, but that is a bit too cryptic for me. I'm using them on breakout garden and installed them via the breakout install script. If I use i2cdetect I only see one address 0x74 in use.

Using the 5x5 matrix alongside the camera freezes the camera

Hi,

I'm not sure exactly why this happens, but on my Raspberry Pi 4 I am having issues with using the RGB5x5 matrix and the Raspberry pi HQ camera.

I can turn on the pi with the camera plugged in and the matrix plugged into the correct GPIO pins, everything runs normally. If I type Raspistill -k into the terminal, the camera will begin to stream a preview overlay in the normal way. However, if I now use the 5x5 matrix using any of the included python code, the camera will freeze. It will not always freeze when the first LED pixel is lit, often it will freeze on the 2nd or 3rd pixel. Once the camera is frozen I have to reset the Pi to get normal operation back again - I cannot get rid of the overlay once it is frozen.

Do you think there could be an issue with i2c communication crossing over here? I thought perhaps it was a power issue, but I am using the official raspberry pi power supply and there's no other evidence of voltage issues.

IOError: [Errno 121] Remote I/O error

Hi,

I am testing this i2c module:

Can you please help to troubleshot this ?
