Today I analyzed LSM6DSO, interface I simulated IIC, the driver was still the same as before, and verified the read ID:

 uint8_t LSM6DSO_Read_Date(uint8_t SlaveAddress, uint8_t RegAddress)
{
    uint8_t recvDate;
    uint8_t succ, stime=0;
    
    I2C_Start();
    succ = I2C_Send_Byte(SlaveAddress & 0xfe);
    while((succ !=1)&&(stime<3))
    {
        I2C_Stop();
        I2C_Start();
        succ = I2C_Send_Byte(SlaveAddress & 0xfe);  //写
        stime++;
    }
    I2C_Send_Byte(RegAddress);
    
    I2C_Start();
    I2C_Send_Byte(SlaveAddress | 0x01);  //读
    recvDate = I2C_Read_Byte(1);   //NACK
    I2C_Stop();
    return recvDate;
}

printf("PID_LSM = %X\r\n",LPS22HH_Read_Date(LSM6DSO_ADD, 0x0F));
