驱动示例代码

#include 

// SET READING PINS ACCORDINGLY TO YOUR ENCODER TO BOARD CONNECTIONS
// Set here your encoder reading pins (Ex.: EC11 with breakout board)
#define clk D5  // esp8266 gpio 14 ->D5  -- EC11-B如果旋转方向相反，与EC11-A对调接线
#define dt D6   // esp8266 gpio 12 ->D6  -- EC11-A
#define sw D7   // esp8266 gpio 13 ->D7 --EC11-M 编码器按压键
