Introduction

TM1814 RGB(W) LED driver for RP2 microcontrollers

Dependencies

This driver depends on:

• Adafruit CircuitPython

Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle or individual libraries can be installed using circup.

Installing to a Connected CircuitPython Device with Circup

Make sure that you have circup installed in your Python environment. Install it with the following command if necessary:

pip3 install circup

With circup installed and your CircuitPython device connected use the following command to install:

circup install adafruit_tm1814

Or the following command to update an existing version:

circup update

Usage Example

import board
import rainbowio
import supervisor
from adafruit_tm1814 import TM1814PixelBackground

# The pin where the LED strip data line is connected
TM1814 = board.A0
# The number of TM1814 controllers
NUM_PIXELS = 100
pixels = TM1814PixelBackground(TM1814, NUM_PIXELS, brightness=0.1)

# Cycle the rainbow at about 1 cycle every 4 seconds
while True:
    pixels.fill(rainbowio.colorwheel(supervisor.ticks_ms() // 16))
