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!
MAX7219Digital tube display control module
MAX7219Is an integrated serial input / output common cathode display driver that connects the microprocessor with an 8-digit 7-segment digital LED display, or a bar graph display or 64 independent LEDs. Which includes an 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 150ALow power off 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! The display is shown in the following figure:
PCB board four corners with copper stud fixed, can effectively prevent short circuit and other unexpected circumstances! Digital tube for the 0.36-inch 4-bit common cathode digital tube This module is compatible with 5V / 3.3V microcontroller (51 / AVR / STM32 .......) Wiring instructions (to provide the program as an example, you can take any IO port, in the process of modifying the port can be defined): VCC 5V GND GND DIN P00 CS P01 CLK P02 Precautions: 1.VCC and GND do not reverse, so as not to burn the chip 2.51 microcontroller P0 port need to pull on the resistor, if your microcontroller is not connected to the pull-up resistor, you can connect the data cable to other ports Shipping list: 1.MAX7219 digital display module 1 2.
