Micro Dot pHAT Driver
Project description
Micro Dot pHAT is an unashamedly old school LED matrix display board, with up to 30x7 pixels, using the Lite-On LTP-305 matrices. Perfect for building a retro scrolling message display or a tiny 30 band spectrum analyser.
Installing
Full install (recommended):
We’ve created an easy installation script that will install all pre-requisites and get your Micro Dot pHAT 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/microdotphat | bashAlternatively, on Raspbian, you can download the pimoroni-dashboard and install your product by browsing to the relevant entry:
sudo apt-get install pimoroni(you will find the Dashboard under ‘Accessories’ too, in the Pi menu - or just run pimoroni-dashboard at the command line)
If you choose to download examples you’ll find them in /home/pi/Pimoroni/microdotphat/.
Manual install:
Library install for Python 3:

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.
