方法一：
char * GetChipUniqueID_Str_STM32F10x(char* stm32id_StrBuf_32char )
{   
    uint32_t chipUniqueID32[3];
    chipUniqueID32[2] = *(__IO uint32_t*)(0X1FFFF7F0);
    chipUniqueID32[1] = *(__IO uint32_t*)(0X1FFFF7EC);
    chipUniqueID32[0] = *(__IO uint32_t*)(0X1FFFF7E8);

    snprintf(stm32id_StrBuf_32char,32,"0x%X-%X-%X", chipUniqueID32[0],chipUniqueID32[2],chipUniqueID32[2]);
    return stm32id_StrBuf_32char;
}

读得的UID是：0x5DBFF30-43084562-43084562

方法二：
uint32_t * GetSTM32MCUIDPMing(uint32_t *id,MCUTypedef type)
{
        // type =1, idAddr[type] =0x1FFFF7E8;
        if(id!=NULL)
        {
                id[0]=*(uint32_t*)(idAddr[type]);
                id[1]=*(uint32_t*)(idAddr[type]+4);
                id[2]=*(uint32_t*)(idAddr[type]+8);
        }
       
        //printf(" STM32_ID_Str(inside):0X%X-%X-%X ",id[0],id[1],id[2]);
        return id;
}

读得的UID是：0x20009068-8000165-800016D;

为何 不相同呢？？
