MAX7219 digital display control module

MAX7219 is an integrated serial input / output common-cathode display driver, which connects the microprocessor 7-segment digital LED display with 8 digits, you can connect a bar graph display or 64 independent LED.
On which includes a B-type BCD encoder chip, multi-channel scanning loop, segment word driver, but also an 8 x 8 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 the general-purpose microprocessor. Each data can be addressed in the update does not need to rewrite all of the display.
MAX7219 also allows users to select each data coding or non-coding.
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 bit data, there is a LED light all the detection mode.
Only three IO ports to drive eight digital tube! Digital flicker-free display! Support cascade!
PCB plate fixed to the four corners of copper studs, which can effectively prevent a short circuit accident occurs!
