TM1638 Key Button Digital Tube Display 8 Bit Electronics Module Board Kit
1. The chip used in this module is TM1638, which combines the three common peripheral circuits of single-chip computer. The biggest feature of this module is that it only needs three IO ports of single-chip computer to drive.
2. Scanning display and key-press scanning need not be interfered by single-chip computer, and only need to read and write relevant registers to send display data or detect keys, thus saving MCU resources. Purchase this module to provide an example program.
3. Usually, we use a single-chip computer to connect 8 LED, 8-digit digital tube, 8 keys, which need to occupy how many IO ports, far more than three IO ports, but with this module can be achieved. Practical application shows that the keys display well.
8-bit digital tube.
VCC GND is connected to 5V power supply, STB CLK DIO is connected to IO port of MCU.
