Product Description
Features:
8 Bits, 8 keys, 8 LEDs, 8 digital tubes, common cathode LED digital tube.
With TM1638 Chip, this module gather more than three common SCM peripheral circuits.
The advantage is only three IO ports will be occupied when it drives.
SCM doesn’t need to work for scaning display and key scaning.
It only need to read the relevant register to send display data or test button so it save MCU resources effectively.
Keys are sensitive and display effectively.
Including the following resources:
8 key
8 LED common cathode
8 a digital tube common cathode
Use TM1638 digital tube drive chip to drive common cathode LED digital tube
How to connect:
VCC GND 5V power supply, STB CLK DIO MCU I/O port
This module for the chip TM1638, set the above three kinds of single chip microcomputer common peripheral circuit, the biggest characteristic is to simply take microcontroller three IO mouth can drive, scanning display and key scan don’t need microcontroller intervention, only need to register to display data related to reading and writing or testing buttons, save MCU resources.
Wiring methods :
VCC connected 5V supply ,
GND connected GND ,
STB CLK DIO connected Microcontroller IO port.
Serial Interface: CLK, STB, DIO
Display mode: 10 segments * 8 segments
Key scan: 8 *3 Bit
Brightness adjustment circuit: 8-level adjustable duty cycle
Oscillation mode: RC oscillation
This product has stable quality and strong anti-interference ability.
This product is mainly used in display drivers for refrigerators, air conditioners, and DIY products.
