MAX7219 is an integrated serial I/O common cathode display driver that connects a microprocessor to an 8-digit 7-segment digital LED display, or to a line graph display or 64 separate LEDs A single module can drive an 8*8 dot matrix common cathode. An external register is used to set the segment current of each LED with 32 fixed screw holes and a diameter of 3mm MAX7219 is a convenient four-wire serial interface that connects all common microprocessors. Each data can be addressed without rewriting all the displays when updating. MAX7219 also allows users to select encoding or no encoding for each data The entire device contains a 150 μ A's low power off mode, analog and digital brightness control, a scan limit register that allows users to display 1-8 bits of data, and a detection mode that enables all LEDs to glow Only 3 I/O ports are needed to drive 1 lattice; No flicker on dot matrix display; Modules with input and output interfaces support cascading
