+# MAX7219 8 digit 7 segment display demo
+
+This example for the max7219_spi_driver and max7219_spi_driver_extended library demonstrates controlling a MAX7219 or MAX7221 based display over SPI.
+
+It demonstrates basic and advanced text writing, and at least one example of every single available display function in some capacity.
+
+---
+
+The MAX7219 and MAX7221 chipsets are used in many 8 character 7 segment and 8x8 single colour dot matrix displays which can be purchased premade on eBay and Aliexpress for a few £/$. The abundance of these displays makes them a great companion for small projects requiring a display output that is more capable than single LEDs but not as complex as something like an LCD.
