Getting Started

Hardware Setup

  1. Connect the Adafruit MatrixPortal M4 to the 64x32 RGB LED matrix.
  2. Power the MatrixPortal M4 using a USB-C cable connected to your computer or a power source.

Software Setup

  1. Install CircuitPython on the MatrixPortal M4
  2. Download the Adafruit CircuitPython Bundle
  3. Copy the following libraries to the lib folder on your CIRCUITPY drive:
    • adafruit_matrixportal
    • adafruit_display_text
    • adafruit_bme280
    • adafruit_bus_device
    • adafruit_register

Connect the BME280 Sensor

  1. Connect the BME280 sensor to the Matrix Portal using I2C:
    • VIN to 3.3V
    • GND to GND
    • SCL to SCL
    • SDA to SDA

Upload the Code

  1. Copy the code.py file from this repository to your CIRCUITPY drive.
