Greatly save your microcontroller resources, do not need to open a timer scan, the liberation of the microcontroller to do more things! Only need to update the display data, pass a data!

MAX7219 digital tube display control module

The MAX7219 is an integrated serial input / output co-cathode display driver that connects a microprocessor with an 8-digit 7-segment digital LED display or a bar graph display or 64 independent LEDs. Which includes a on-chip B-type BCD encoder, multi-scan circuit, segment word drive, but also a 8 * 8 static RAM used to store each data. Only one external register is used to set the segment current for each LED.

A convenient four-wire serial interface can be connected to all common microprocessors. Each data can be addressed at the time of updating without having to rewrite all the displays. The MAX7219 also allows the user to select or not code for each data.

The entire device contains a 150μA low power shutdown mode, analog and digital brightness control, a scan limit register allows the user to display 1-8 bits of data, and a test mode for all LEDs to emit light.

Only need three IO port can drive 8 digital tube! Digital tube display without flicker! Support cascade.

PCB board four corners with copper stud fixed, can effectively prevent short circuit and other unexpected circumstances!
