Description

功能介紹

包括以下資源:

1. 8個按鍵，

2. 8個LED

3. 8位數碼管，共陰極LED數碼管；

4. 可以和STC等單片機直接連接；

5. 提供ardiuno驅動程序；


該模塊所用芯片為TM1638，集合了以上三種單片機常見外圍電路，最大特點是只需佔用單片機三個IO口即可驅動，掃描顯示和按鍵掃描不需要單片機干預，只需要讀寫相關寄存器送顯示數據或檢測按鍵，節省MCU資源。購買該模塊提供實例程序。


試想下，我們平時使用單片機外接8個LED，8位數碼管，8個按鍵這需佔用多少個IO口，遠不止3個IO口吧，但用這個模塊就可以實現。經實際應用，按鍵靈敏顯示效果良好。


接線方法：

VCC GND接5V電源， STB CLK DIO接單片機IO口。
