MPU6050代码
MSP432是德州仪器(Texas Instruments)推出的一款采用ARM Cortex-M4F内核的微控制器,它具有低功耗、高性能和丰富的外设功能,可以广泛应用于物联网、工业自动化、智能家居等领域。而MPU6050是一款集成了三轴陀螺仪和三轴加速度计的运动传感器,常用于姿态测量、手势识别、智能车等项目。
在使用MSP432微控制器与MPU6050传感器进行交互时,可以利用Keil C51编译器编写代码。下面是一段示例代码,用来读取MPU6050的加速度计数据:
```
#include <msp.h>
// I2C初始化
void I2C_Init(void)
{
// 配置I2C引脚
P1->SEL0 |= BIT6 | BIT7;
P1->SEL1 &= ~(BIT6 | BIT7);
// 配置I2C时钟
EUSCI_B0->CTLW0 |= EUSCI_A_CTLW0_SWRST;
EUSCI_B0->CTLW0 = EUSCI_A_CTLW0_SWRST | EUSCI_A_CTLW0_MODE_3 | EUSCI_A_CTLW0_MST | EUSCI_A_CTLW0_SYNC | EUSCI_B_CTLW0_SSEL__SMCLK;
EUSCI_B0->BRW = 10;
EUSCI_B0->CTLW0 &= ~EUSCI_A_CTLW0_SWRST;
}
// I2C发送数据
void I2C_SendData(uint8_t addr, uint8_t reg, uint8_t data)
{
while (EUSCI_B0->STATW & EUSCI_B_STATW_BBUSY);
EUSCI_B0->I2CSA = addr;
EUSCI_B0->CTLW0 |= EUSCI_A_CTLW0_TR;
EUSCI_B0->CTLW0 |= EUSCI_A_CTLW0_TXSTT;
while (!(EUSCI_B0->IFG & EUSCI_B_IFG_TXIFG0));
EUSCI_B0->TXBUF = reg;
while (!(EUSCI_B0->IFG & EUSCI_B_IFG_TXIFG0));
EUSCI_B0->TXBUF = data;
while(!(EUSCI_B0->IFG & EUSCI_B_IFG_TXIFG0));
EUSCI_B0->CTLW0 |= EUSCI_A_CTLW0_TXSTP;
while (EUSCI_B0->CTLW0 & EUSCI_A_CTLW0_STT);
}
// I2C接收数据
uint8_t I2C_ReadData(uint8_t addr, uint8_t reg)
{
while (EUSCI_B0->STATW & EUSCI_B_STATW_BBUSY);
EUSCI_B0->I2CSA = addr;
EUSCI_B0->CTLW0 &= ~EUSCI_A_CTLW0_TR;
EUSCI_B0->CTLW0 |= EUSCI_A_CTLW0_TXSTT;
while (!(EUSCI_B0->IFG & EUSCI_B_IFG_TXIFG0));
EUSCI_B0->TXBUF = reg;
while (!(EUSCI_B0->IFG & EUSCI_B_IFG_TXIFG0));
EUSCI_B0->CTLW0 |= EUSCI_A_CTLW0_TXSTP;
while (EUSCI_B0->STATW & EUSCI_B_STATW_BBUSY);
EUSCI_B0->CTLW0 |= EUSCI_A_CTLW0_TXSTT;
while (EUSCI_B0->CTLW0 & EUSCI_A_CTLW0_STT);
while (!(EUSCI_B0->IFG & EUSCI_B_IFG_RXIFG0));
uint8_t data = EUSCI_B0->RXBUF;
while (EUSCI_B0->STATW & EUSCI_B_STATW_BBUSY);
EUSCI_B0->CTLW0 |= EUSCI_A_CTLW0_TXSTP;
return data;
}
int main(void)
{
// 初始化I2C
I2C_Init();
while (1)
{
// 读取MPU6050的加速度计数据
uint8_t highByte = I2C_ReadData(0x68, 0x3B);
uint8_t lowByte = I2C_ReadData(0x68, 0x3C);
int16_t aValue = (highByte << 8) | lowByte;
// 处理加速度计数据
// ...
// 延时
for (volatile uint32_t i = 0; i < 10000; i++);
}
}
```
以上是一个基本的示例代码,用于与MSP432微控制器和MPU6050传感器进行通信,并读取加速度计数据。在实际应用中,还需要根据具体的需求进行相应的处理和操作,比如计算姿态角、进行滤波处理等。
