A C++ library (with Python bindings) for driving HUB75-style RGB LED matrix panels directly from Raspberry Pi GPIO pins, supporting multiple chained panels with up to 11-bit PWM per channel. It includes demo binaries and utility tools for displaying content on the panels.
Use cases
- drive an RGB LED matrix panel from a Raspberry Pi
- display scrolling text or images on LED panels
- build a LED matrix clock or info display
- chain multiple 64x64 LED panels on a Raspberry Pi
- render animations on HUB75 panels with 24-bit color
- create a Raspberry Pi LED sign
When to choose
- you have HUB75-style RGB LED panels and a Raspberry Pi
- you need high refresh rates and true 24-bit color via PWM
- you want a mature, well-documented C/C++ or Python API for LED matrices
When to avoid
- you use PWM-based LED panels, which need a different driver
- your project is not on Raspberry Pi hardware
- you need a plug-and-play application rather than a programming library
