用小华半导体HC32L17x_DDL_Rev1.2.0中的i2c_mcu_master_int样例，改写一个SHT30温湿度传感器数据采集的程序

好的，下面是一个基于HC32L17x_DDL_Rev1.2.0中的i2c_mcu_master_int样例修改的SHT30温湿度传感器数据采集程序：

#include "hc32l17x.h"
#include "i2c.h"

#define SHT30_ADDR 0x44

static stc_i2c_config_t stcI2cCfg = {
    .enFunc = Enable,
    .u32Baudrate = 100000,
    .enClkDiv = I2cPclkDiv1,
    .enI2cMode = I2cMaster,
    .enI2cAck = I2cAck,
    .u8SlaveAddr = 0,
};

static void SHT30_Init(void)
{
    /* I2C GPIO config */
    Gpio_SetFunc_I2CSCK3_0(0u);
    Gpio_SetFunc_I2CSDA3_0(0u);

    /* I2C config */
    M4_I2C3_Init(&stcI2cCfg);
}

static uint8_t SHT30_Send_Cmd(uint16_t cmd)
{
    uint8_t u8TxData[2] = {0};
    uint8_t u8RxData[2] = {0};

    u8TxData[0] = (uint8_t)(cmd >> 8);
    u8TxData[1] = (uint8_t)cmd;

    /* Send command */
    if (Ok != M4_I2C3_Transmit(SHT30_ADDR, u8TxData, 2u, I2cFmStart)) {
        return Error;
    }

    /* Delay for measurement */
    Ddl_Delay1ms(20u);

    /* Receive data */
    if (Ok != M4_I2C3_Receive(SHT30_ADDR, u8RxData, 2u, I2cFmStop)) {
        return Error;
    }

    return u8RxData[0];
}

static uint16_t SHT30_Get_Humidity(void)
{
    uint16_t u16Humidity = 0;
    uint8_t u8Crc = 0;

    /* Send measurement command */
    if (Ok != SHT30_Send_Cmd(0x2400)) {
        return 0;
    }

    /* Calculate humidity */
    u16Humidity = (uint16_t)SHT30_Send_Cmd(0xE000);

    /* Calculate CRC */
    u8Crc = (uint8_t)(u16Humidity >> 8);
    u16Humidity &= 0xFF;
    if (u8Crc != (uint8_t)(0xFFu & ((u16Humidity + (u16Humidity >> 8))))) {
        return 0;
    }

    return u16Humidity;
}

static uint16_t SHT30_Get_Temperature(void)
{
    uint16_t u16Temperature = 0;
    uint8_t u8Crc = 0;

    /* Send measurement command */
    if (Ok != SHT30_Send_Cmd(0x2400)) {
        return 0;
    }

    /* Calculate temperature */
    u16Temperature = (uint16_t)SHT30_Send_Cmd(0xE000);

    /* Calculate CRC */
    u8Crc = (uint8_t)(u16Temperature >> 8);
    u16Temperature &= 0xFF;
    if (u8Crc != (uint8_t)(0xFFu & ((u16Temperature + (u16Temperature >> 8))))) {
        return 0;
    }

    return u16Temperature;
}

int main(void)
{
    /* Init SHT30 */
    SHT30_Init();

    while (1) {
        /* Get and print temperature and humidity */
        uint16_t u16Temperature = SHT30_Get_Temperature();
        uint16_t u16Humidity = SHT30_Get_Humidity();
        printf("Temperature: %d.%d C, Humidity: %d.%d %%RH\n",
            (int)(-45.0 + 175.0 * (float)u16Temperature / 65535.0),
            (int)(100.0 * (float)u16Temperature / 65535.0) % 100,
            (int)(100.0 * (float)u16Humidity / 65535.0),
            (int)(10000.0 * (float)u16Humidity / 65535.0) % 100);
        Ddl_Delay1ms(1000u);
    }
}

这个程序中，我们先调用SHT30_Init()函数初始化I2C外设和GPIO，然后通过SHT30_Send_Cmd()函数向SHT30发送命令并接收采集到的数据。SHT30_Get_Humidity()和SHT30_Get_Temperature()函数分别用于获取湿度和温度数据，并且计算出相应的数值。在主函数中，我们不断循环获取并打印温湿度数据，以便进行实时监测。
