恒温器七段式



我正在用arduino mega 2560制作一个恒温器。我想调整所需的温度，并将其显示在两个单独的七段显示器上。我的问题是它不起作用。我认为问题在于当我调用函数时。我希望有人能帮我做这个项目。这是我的无效循环代码

void loop() {
buttonStateP = digitalRead(buttonPinP);

Wire.write(0x3B); // starting with register 0x3B (ACCEL_XOUT_H) [MPU-6000 and MPU-6050 Register Map and Descriptions Revision 4.2, p.40]
Wire.endTransmission(false); // the parameter indicates that the Arduino will send a restart. As a result, the connection is kept active.
Wire.requestFrom(MPU_ADDR, 7*2, true); // request a total of 7*2=14 registers
// "Wire.read()<<8 | Wire.read();" means two registers are read and stored in the same variable
accelerometer_x = Wire.read()<<8 | Wire.read(); // reading registers: 0x3B (ACCEL_XOUT_H) and 0x3C (ACCEL_XOUT_L)
