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
