Product description Product description Description: MAX7219 is an integrated serial input / output common-cathode display drivers , which connects the microprocessor 7-segment digital LED display with 8 digits , bar graph can also be connected monitor or 64 separate LED. On type B BCD encoder includes an on-chip , multi-channel scanning loop , segment word drive, but also a 8x8 static RAM for storing each data . Only one external register is used to set the segment current for each LED. A convenient four-wire serial interface can connect all common microprocessor. Each data can be addressed in the update does not overwrite all of the display . MAX7219 also allows the user to select each of the data code or not coded. The entire device includes a 150A low-power shutdown mode , analog and digital brightness control , a scan-limit register allows the user to 1-8 bits of data , there is an LED light so that all the detection mode. Wiring instructions: 1,Module on the left as an input port, output port on the right. 2,Control of a single module, simply input port to the CPU. 3,more modules cascade input termination module of a CPU, 2 output termination module input and output of the two modules is terminated with the input end of the first three modules, and so on. 51 MCU, for example: VCC → 5V GND → GND DIN → P22 CS → P21 CLK → P20 Package list: 1 X MAX7219 dot matrix module 1 X DuPont line 5pin
