About the Application

This application shows how to use the SSI object to communicate with a MAX7219 IC driving an 8-digit LED display.

The line mapping is as follows:

  • Load: GPIO 46
  • Clock: GPIO 47
  • Din: GPIO 48

Important note: To use this application, you must read the MAX7219 manual. It may not work otherwise, as the display has several modes of operation.
