MAX7219 dot matrix module microcontroller module control module display module 16 in one

\\\\

 

\\\\

MAX7219 Is a kind of integrated serial input/Output common cathode display driver,It connects the microprocessor with theEightBit numberSevenSegment numberLEDDisplay, you can also connect the line diagram display orSixty-fourIndependent.LED. It includes a piece ofBtypeBCDEncoder, multiple scan circuit, segment word driver, and there is also a8*8StaticRAMUsed to store every data. Only one external register is used to set eachLEDSegment current.

\\\\

A convenient four wire serial interface can be connected to all general-purpose microprocessor. Each data can be addressed in the update without rewriting all the display.MAX7219It also allows the user to select or not encode each data.
The entire device contains a150 AThe low power off mode, analog and digital brightness control, a scan limit register allows the user to display1-8Bit data, and one for allLEDDetection mode of luminescence.
