# Wemos D1 Mini Matrix LED shield driver for micropython

## Introduction

This is an implementation of the driver for the Wemos D1 Mini

Matrix LED shield, which utilizes the TM1640 chip by Titan Micro.

It implements a weird protocol, which reminds both of I2C and SPI

but is not compatible with either. This is why we bitbang.

This code has been optimized for use with the Matrix LED

shield by Wemos. It has been tested on a Wemos D1 Mini and

an MH-ET Live MiniKit, using micropython 1.9.2.

Protocol implementation was derived from Wemos'

[own implementation](https://github.com/wemos/WEMOS_Matrix_LED_Shield_Arduino_Library/) of the driver for Arduino.

## Functionality

- Modify the state of individual pixels

- draw an 8x8 bitmap

- set the brightness

### Animations

Animation functions are in a separate class. These will allow

you to define a simple multi-frame animation.

## Usage

Please see `example.py` for example usage.
