+## 例程
+
+### 1. Arduino IDE
+
+```c++
+/*
+* 读取齿轮电位器的数据
+*/
+Wire.requestFrom(0x62, 2);
+
+if(Wire.available()) {
+    encode  = Wire.read();//read value of encoder
+    if(press_n  == 0xff) {
+        pressed = 0;//button released
+    }
+    else {
+        pressed = 1;//button pressed
+    }
+}
+```
