以下是使用STM32和MPU6050模块的示例代码:
```c
#include "stm32f4xx.h"
#include "stdio.h"
#include "i2c.h"
#define MPU6050_ADDR 0xD0
void MPU6050_Init(void);
void MPU6050_Read_Accel(float *ax, float *ay, float *az);
void MPU6050_Read_Gyro(float *gx, float *gy, float *gz);
int main(void)
{
float ax, ay, az;
float gx, gy, gz;
MPU6050_Init();
while(1)
{
MPU6050_Read_Accel(&ax, &ay, &az);
MPU6050_Read_Gyro(&gx, &gy, &gz);
printf("accel: %.2f, %.2f, %.2f\r\n", ax, ay, az);
printf("gyro: %.2f, %.2f, %.2f\r\n\r\n", gx, gy, gz);
DelayMs(1000);
}
}
void MPU6050_Init(void)
{
uint8_t data;
// Set power management register to wake up MPU6050
data = 0x00;
I2C_Write(MPU6050_ADDR, 0x6B, &data, 1);
// Set sample rate divider to 1kHz
data = 0x07;
I2C_Write(MPU6050_ADDR, 0x19, &data, 1);
// Set gyro range to +/- 250 degrees per second
data = 0x00;
I2C_Write(MPU6050_ADDR, 0x1B, &data, 1);
// Set accelerometer range to +/- 2g
data = 0x00;
I2C_Write(MPU6050_ADDR, 0x1C, &data, 1);
}
void MPU6050_Read_Accel(float *ax, float *ay, float *az)
{
uint8_t data[6];
// Read accelerometer data
I2C_Read(MPU6050_ADDR, 0x3B, data, 6);
// Convert raw data to g's
*ax = (float)((int16_t)(data[0] << 8 | data[1])) / 16384.0;
*ay = (float)((int16_t)(data[2] << 8 | data[3])) / 16384.0;
*az = (float)((int16_t)(data[4] << 8 | data[5])) / 16384.0;
}
void MPU6050_Read_Gyro(float *gx, float *gy, float *gz)
{
uint8_t data[6];
// Read gyro data
I2C_Read(MPU6050_ADDR, 0x43, data, 6);
// Convert raw data to degrees per second
*gx = (float)((int16_t)(data[0] << 8 | data[1])) / 131.0;
*gy = (float)((int16_t)(data[2] << 8 | data[3])) / 131.0;
*gz = (float)((int16_t)(data[4] << 8 | data[5])) / 131.0;
}
```
此代码使用I2C通信协议与MPU6050模块进行通信,并读取其加速度计和陀螺仪数据。请注意,此代码仅适用于STM32F4系列微控制器,如果您使用其他系列的微控制器,可能需要进行相应的修改。
