sensors_event_t a, g, temp; mpu.getEvent(&a, &g, &temp);这两段代码怎么用

&a, &g, &temp);

This code is using the MPU (Motion Processing Unit) library to read data from an MPU sensor. The MPU sensor has multiple sensors within it, including an accelerometer, a gyroscope, and a temperature sensor.

The code is declaring three variables of type sensors_event_t - a, g, and temp. These variables will be used to store the data from the accelerometer, gyroscope, and temperature sensor respectively.

The function mpu.getEvent() is being called to read the data from the sensor. This function takes three arguments - the accelerometer data, the gyroscope data, and the temperature data - and stores the data in the corresponding variables (a, g, and temp).

Overall, this code is reading data from an MPU sensor and storing it in variables for further processing.
