Demo MAX7219 library on MIKROELEKTRONIKA Serial 7-Seg Display 8-Digit This demo has been tested on NUCLEO-F411RE
For 7 segments display : https://www.mikroe.com/serial-7-seg-8-digit-board
For MAX7219 https://www.maximintegrated.com/en/products/power/display-power-control/MAX7219.html
use library https://os.mbed.com/teams/Maxim-Integrated/code/MAX7219/
7 segments display is connected to default SPI on Arduino connectors. STM32 MISO on RC5_PB5 (MOSI) STM32 MOSI on MISO STM32 SCK on RC3_RF3 (SCK) STM32 SS on CS0 5v GND
