esp8266-hw-spi-max7219-7seg

Arduino library for 7segment max7219 modules conncted to ESP8266 using HW SPI

IMPORTANT - HEADER FILE NAME CHANGED

Since commit 3124929f5ad056c64b6a8e815474faaf1db048b1 the header file name was changed from esp8266-hw-spi-max7219-7seg.h to esp8266_hw_spi_max7219_7seg.h to avoid warnings during compilation.

You need to change the

#include <esp8266-hw-spi-max7219-7seg.h>

line to

#include <esp8266_hw_spi_max7219_7seg.h>

in your project (.ino file) if you can't compile it after update of this library because of

esp8266-hw-spi-max7219-7seg.h: No such file or directory

error.

Supports

  • chained modules
  • displaying of numbers and characters A-Z including decimal dots
  • using ESP8266 HW SPI

Hardware setup:

  • GPIO13 -> DIN
  • GPIO14 -> CLK
  • anyother -> CS
