蓝牙模块 ADXL345
我买了一个ADXl345的模块。我找到了与电脑通讯的程序，但是我想要让回馈的变量可以控制。请求大神帮助 （可否帮我加一个x轴在0-100的范围，led10灯亮） #include #define Register_ID 0 #define Register_2D 0x2D #define Register_X0 0x32 #define Register_X1 0x33 #define Register_Y0 0x34 #define Register_Y1 0x35 #define Register_Z0 0x36 #define Register_Z1 0x37 int ADXAddress = 0xA7 >> 1; // the default 7-bit slave address int reading = 0; int val = 0; int X0, X1, X_out; int Y0, Y1, Y_out; int Z1, Z0, Z_out; double Xg, Yg, Zg; void setup() { Wire.begin(); Serial.begin(9600); delay(100); // 能够测量数据 Wire.beginTransmission(ADXAddress); Wire.write(Register_2D); Wire.write(8); //measuring enable Wire.endTransmission(); // stop transmitti ng } void loop() { //--------------X Wire.beginTransmission(ADXAddress); // transmit to device Wire.write(Register_X0); Wire.write(Register_X1); Wire.endTransmission(); Wire.requestFrom(ADXAddress, 2); if (Wire.available() <= 2) { X0 = Wire.read(); X1 = Wire.read(); X1 = X1 << 8; X_out = X0 + X1; } Xg = X_out; Serial.print("X= "); Serial.print(Xg); Serial.print(" "); delay(1000); }
