【问题描述】：
所以，我使用的是 Raspberry pi 和 Arduino Uno，通过串行通信将它们连接起来。 我通过 python 库 pySerial 接收串行数据到 Rpi。 我已成功接收到 LED 开关动作等一般 I/O 数据。
现在我正在连接一个适用于 I2C 和 SPI 协议的 MPU9250（9 轴罗盘），我从 github 下载了 zip 库。
我知道我可以通过 I2C 通信直接使用 pi 操作传感器，但我想尝试完全使用 Arduino IDE。 我上传到董事会的代码是这样的：

#include "MPU9250.h"
// an MPU9250 object with the MPU-9250 sensor on I2C bus 0 with address 0x68
MPU9250 IMU(Wire,0x68);
int status;
void setup() {
// serial to display data
Serial.begin(115200);
while(!Serial) {}
// start communication with IMU
status = IMU.begin();
if (status < 0) {
Serial.println("IMU initialization unsuccessful");
Serial.println("Check IMU wiring or try cycling power");
Serial.print("Status: ");
Serial.println(status);
while(1) {}
}
}
void loop() {
// read the sensor
IMU.readSensor();
// display the data
Serial.print(IMU.getAccelX_mss(),6);
Serial.print("\t");
Serial.print(IMU.getAccelY_mss(),6);
Serial.print("\t");
Serial.print(IMU.getAccelZ_mss(),6);
Serial.print("\t");
Serial.print(IMU.getGyroX_rads(),6);
Serial.print("\t");
Serial.print(IMU.getGyroY_rads(),6);
Serial.print("\t");
Serial.print(IMU.getGyroZ_rads(),6);
Serial.print("\t");
Serial.print(IMU.getMagX_uT(),6);
Serial.print("\t");
Serial.print(IMU.getMagY_uT(),6);
Serial.print("\t");
Serial.print(IMU.getMagZ_uT(),6);
Serial.print("\t");
Serial.println(IMU.getTemperature_C(),6);
delay(100);
}
在这里，我得到了库的成功导入消息，但是当我编译代码时，我得到了这个错误：
MPU9250.h:28:36: fatal error: Wire.h: No such file or directory
即使该文件存在于 zip 文件中并且在库中，我也面临这个问题。谁能帮我这个？您的帮助将不胜感激。 如果您对我提供的任何澄清有任何问题，请告诉我。 此外，我已经在我的窗口中成功编译了库并正确获得了结果。
