A MicroPython library for the Max7219 8x8 LED matrix driver
Project description
MicroPython Max7219 8x8 LED Matrix
A MicroPython library for the MAX7219 8x8 LED matrix driver using the SPI interface.Supports cascading matrices extending the framebuf class.
Examples
Raspberry Pi Pico
| Pico | max7219 |
|---|---|
| 40 (VBUS) | VCC 5V |
| 38 (GND) | GND |
| 5 (GP3) | DIN |
| 7 (GP5) | CS |
| 4 (GP2) | CLK |
from machine import Pin, SPI
from max7219 import Matrix8x8
spi = SPI(0, baudrate=10000000, polarity=1, phase=0, sck=Pin(2), mosi=Pin(3))
ss = Pin(5, Pin.OUT)
display = Matrix8x8(spi, ss, 4)
display.brightness(5)
display.fill(0)
display.show()
display.text("CODE")
display.show()
