TM1638 8-Bit Key Digital Tube LED Display Module
Include The Following Resources:
1. 8 keys,
2. 8 LEDs,
3. 8-bit digital tube
The chip used in this module is TM1638, which integrates the three common peripheral circuits of the single chip microcomputer. The biggest feature is that it only needs to occupy three IO ports of the single chip microcomputer to drive. Scan display and key scanning do not require the intervention of the single chip microcomputer, but only need to read and write relevant registers to send display data or detect keys, saving MCU resources.
Imagine how many IO ports we use to connect 8 LEDs, 8 digital tubes, and 8 buttons to a single chip computer, far more than 3 IO ports. However, this module can be used to achieve this. After practical application, the key sensitivity display effect is good.
Wiring Method:
VCC GND is connected to a 5V power supply, and STB CLK DIO is connected to the microcontroller IO port.
