根据手册可知 UID和UCID 的地址

代码如下

#define UID_Addr             (0x1FFFF7F0)
#define UCID_Addr             (0x1FFFF7C0)

uint8_t UID[12] = {0};
uint8_t UCID[16] = {0};

void Read_Flash_Data(u8* pBuffer, u32 NumToRead, u32 ReadAddr)
{
u32 i;
for (i = 0; i < NumToRead; i++)
{
      *((u8*)pBuffer + i) = *((u8*)ReadAddr + i);
}
}

void USART2_Configuration(void)
{
USART_InitType USART_InitStructure;
GPIO_InitType GPIO_InitStructure;
GPIO_InitStruct(&GPIO_InitStructure);

RCC_EnableAPB2PeriphClk(RCC_APB2_PERIPH_GPIOB, ENABLE);
RCC_EnableAPB1PeriphClk(RCC_APB1_PERIPH_USART2, ENABLE);

GPIO_InitStructure.Pin          = GPIO_PIN_4;
GPIO_InitStructure.GPIO_Mode    = GPIO_Mode_AF_PP;
GPIO_InitStructure.GPIO_Alternate = GPIO_AF4_USART2;
GPIO_InitPeripheral(GPIOB, &GPIO_InitStructure);

GPIO_InitStructure.Pin          = GPIO_PIN_5;
GPIO_InitStructure.GPIO_Pull    = GPIO_Pull_Up;
GPIO_InitStructure.GPIO_Alternate = GPIO_AF4_USART2;
GPIO_InitPeripheral(GPIOB, &GPIO_InitStructure);

USART_StructInit(&USART_InitStructure);
USART_InitStructure.BaudRate          = 115200;
USART_InitStructure.WordLength       = USART_WL_8B;
USART_InitStructure.StopBits          = USART_STPB_1;
USART_InitStructure.Parity             = USART_PE_NO;
USART_InitStructure.HardwareFlowControl = USART_HFCTRL_NONE;
USART_InitStructure.Mode             = USART_MODE_RX | USART_MODE_TX;

USART_Init(USART2, &USART_InitStructure);
USART_Enable(USART2, ENABLE);
}

int fputc(int ch, FILE* f)
{
USART_SendData(USART2, (uint8_t)ch);
while (USART_GetFlagStatus(USART2, USART_FLAG_TXDE) == RESET);
return (ch);
}

int main(void)
{
int i = 0;

USART2_Configuration();

Read_Flash_Data(UID, 12, UID_Addr);
Read_Flash_Data(UCID, 16, UCID_Addr);

printf("UID:0x");
for(i = 0; i < 12; i++)
{
printf("%02x", UID);
}
printf("\r\n\r\n\r\n");

printf("UCID:0x");
for(i = 0; i < 16; i++)
{
printf("%02x", UCID);
}
printf("\r\n\r\n\r\n");
}

串口打印如下

UID:0x360213503447373031058929

UCID:0x360213160e5034473730313030058929
