如何使用msp430g2553读取msp180的测量数据，请写出代码

要使用MSP430G2553读取MSP180的测量数据，您需要连接MSP180传感器到MSP430G2553的I2C总线上。以下是一个基本的读取MSP180数据的示例代码：

#include <msp430.h>
#include <stdint.h>

#define MSP180_ADDR 0x77 // MSP180传感器的I2C地址
#define MSP180_CMD 0x2E // MSP180传感器开始测量的命令
#define MSP180_DATA_LEN 2 // MSP180传感器返回的数据长度

void i2c_init(void)
{
    // 配置I2C端口
    P1SEL |= BIT6 + BIT7;
    P1SEL2 |= BIT6 + BIT7;
  
    // 配置I2C时钟
    UCB0CTL1 |= UCSWRST;
    UCB0CTL0 = UCMST + UCMODE_3 + UCSYNC;
    UCB0CTL1 = UCSSEL_2 + UCSWRST;
    UCB0BR0 = 10;
    UCB0BR1 = 0;
    UCB0I2CSA = MSP180_ADDR;
    UCB0CTL1 &= ~UCSWRST;
}

void i2c_start(void)
{
    UCB0CTL1 |= UCTR + UCTXSTT;
    while (UCB0CTL1 & UCTXSTT);
}

void i2c_stop(void)
{
    UCB0CTL1 |= UCTXSTP;
    while (UCB0CTL1 & UCTXSTP);
}

void i2c_write_byte(uint8_t byte)
{
    UCB0TXBUF = byte;
    while (!(UCB0IFG & UCTXIFG));
}

uint16_t i2c_read_word(void)
{
    uint16_t data = 0;
    UCB0CTL1 &= ~UCTR;
    UCB0CTL1 |= UCTXSTT;
    while (UCB0CTL1 & UCTXSTT);
    UCB0CTL1 |= UCTXSTP;
    while (UCB0CTL1 & UCTXSTP);
    data = (UCB0RXBUF << 8) & 0xFF00;
    UCB0CTL1 &= ~UCTR;
    UCB0CTL1 |= UCTXSTT;
    while (UCB0CTL1 & UCTXSTT);
    UCB0CTL1 |= UCTXSTP;
    while (UCB0CTL1 & UCTXSTP);
    data |= UCB0RXBUF;
    return data;
}

uint16_t msp180_read(void)
{
    uint16_t data = 0;
    i2c_start();
    i2c_write_byte(MSP180_CMD);
    i2c_stop();
    __delay_cycles(10000);
    i2c_start();
    data = i2c_read_word();
    i2c_stop();
    return data;
}

int main(void)
{
    WDTCTL = WDTPW + WDTHOLD; // 停用看门狗
    i2c_init(); // 初始化I2C总线
    uint16_t msp180_data = msp180_read(); // 读取MSP180数据
    return 0;
}

请注意，这只是一个基本的示例代码，并且可能需要根据您的硬件和应用程序进行修改。此外，您需要确保正确连接MSP180到MSP430G2553的I2C总线上。
