adafruit / Adafruit_CircuitPython_HT16K33

Adafruit CircuitPython driver for the HT16K33, a LED matrix driver IC.

Introduction

This is a library for using the I²C-based LED matrices with the HT16K33 chip. It supports both 16x8 and 8x8 matrices, as well as 7- and 14-segment displays.

• Notes

  1. This library is intended for Adafruit CircuitPython's API. For a library compatible with MicroPython machine API see this library.
  2. This library does not work with the Trellis 4x4 LED+Keypad board. For that product use: CircuitPython Trellis Library

Dependencies

This driver depends on:

• Adafruit CircuitPython
• Bus Device

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.

Installing from PyPI

On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:

pip3 install adafruit-circuitpython-ht16k33

To install system-wide (this may be required in some cases):

sudo pip3 install adafruit-circuitpython-ht16k33

To install in a virtual environment in your current project:

mkdir project-name && cd project-name
python3 -m venv .venv
source .venv/bin/activate
pip3 install adafruit-circuitpython-ht16k33
