ACEIRMC 2PCS MAX7219 Dot Matrix Display Module Single-Chip Control LED Module DIY Kit for Arduino with 5pin Line (A)
Description
Description Wiring instructions Module on the left as an input port, output port on the right. Control of a single module, simply input port to the CPU 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 Notice Requires only three IO ports can drive a dot ! No flashing dot matrix display ! Support cascade ! Package list 2 X MAX7219 dot matrix module 2 X DuPont line 5pin Read more 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.
