引用原子哥的代码stmflash.c 和stm32flash.h 程序如下
程序一：
#include "stm32f10x.h"
#include "usart.h"
#include "stmflash.h"

const u8 TEXT_Buffer[]={"I like MCU"};
#define SIZE sizeof(TEXT_Buffer)            //数组长度
#define FLASH_SAVE_ADDR  0X08070000 //设置FLASH 保存地址(必须为偶数，且其值要大于本代码所占用FLASH的大小+0X08000000)

int main(void)
{

u8 datatemp[SIZE];

USART1_Configuration(115200);
printf("Uart1 is OK!!!\r\n");

STMFLASH_Write(FLASH_SAVE_ADDR,(u16*)TEXT_Buffer,SIZE );
printf("FLASH Write Finished!\r\n");

printf("存入数据为：%s \r\n",TEXT_Buffer);

STMFLASH_Read(FLASH_SAVE_ADDR,(u16*)datatemp,SIZE );
printf("\r\n 读取数据为: %s \r\n",datatemp);

while(1);
}

程序一运行结果：
Uart1 is OK!!!

FLASH Write Finished!

存入数据为：I like MCU

读取数据为: I like MCU

程序二
#include "stm32f10x.h"
#include "usart.h"
#include "stmflash.h"

const u8 TEXT_Buffer[]={"I like MCU"};
#define SIZE sizeof(TEXT_Buffer)            //数组长度
#define FLASH_SAVE_ADDR  0X08070000 //设置FLASH 保存地址(必须为偶数，且其值要大于本代码所占用FLASH的大小+0X08000000)

int main(void)
{

u8 datatemp[SIZE];

USART1_Configuration(115200);
printf("  Uart1 is OK!!!\r\n");

// STMFLASH_Write(FLASH_SAVE_ADDR,(u16*)TEXT_Buffer,SIZE);
// printf("FLASH Write Finished!\r\n");

// printf("存入数据为：%s \r\n",TEXT_Buffer);

STMFLASH_Read(FLASH_SAVE_ADDR,(u16*)datatemp,SIZE);
printf("\r\n 读取数据为: %s \r\n",datatemp);

       while(1);

}

程序二运行结果
Uart1 is OK!!!

读取数据为:
