MAX7219 8x8 Dot Matrix Display ModuleThe MAX7219 is a serial input output common cathode display driver that is attached to a microprocessor and has an 8 digit 7 segment digital LED display that may also be connected to a bar graph display or 64 independent LEDs. To store each data, an On B BCD encoder with an on chip, multi channel scanning loop word drive and an 8 x 8 static RAM is employed. To set the current of each LED section, just one external register is used. All general purpose
