STM32读写内部flash的问题（急求啊，原子哥，谢谢了啊）

void STMFLASH_Write(u32 WriteAddr,u16 *pBuffer,u16 NumToWrite)

{

u32 secpos;    //???????·

u16 secoff;    //?????????????·(16??×?????)

u16 secremain; //?????????à???·(16??×?????)    

  u16 i;    

u32 offaddr;   //????0X08000000?ó?????·

if(WriteAddr<STM32_FLASH_BASE||(WriteAddr>=(STM32_FLASH_BASE+1024*STM32_FLASH_SIZE)))return;//·?·¨???·

FLASH_Unlock(); //????

offaddr=WriteAddr-STM32_FLASH_BASE; //???????????·.

secpos=offaddr/STM_SECTOR_SIZE; //???????·  0~127 for STM32F103RBT6

secoff=(offaddr%STM_SECTOR_SIZE)/2; //??????????????(2??×??????ù±?????.)

secremain=STM_SECTOR_SIZE/2-secoff; //???????à?????ó??   

if(NumToWrite<=secremain)secremain=NumToWrite;//???ó????????·??§

while(1) 

{

STMFLASH_Read(secpos*STM_SECTOR_SIZE+STM32_FLASH_BASE,STMFLASH_BUF,STM_SECTOR_SIZE/2);//??????????????????

for(i=0;i<secremain;i++)//???é????

{

if(STMFLASH_BUF[secoff+i]!=0XFFFF)break;//?è??????     

}

if(i<secremain)//?è??????

{

FLASH_ErasePage(secpos*STM_SECTOR_SIZE+STM32_FLASH_BASE);//????????????

for(i=0;i<secremain;i++)//????

{

STMFLASH_BUF[i+secoff]=pBuffer;   

}

STMFLASH_Write_NoCheck(secpos*STM_SECTOR_SIZE+STM32_FLASH_BASE,STMFLASH_BUF,STM_SECTOR_SIZE/2);//????????????  

}else STMFLASH_Write_NoCheck(WriteAddr,pBuffer,secremain);//??????????????,?±?????????????à????.     

if(NumToWrite==secremain)break;//?????á????

else//???????á??

{

secpos++; //???????·??1

secoff=0; //??????????0   

    pBuffer+=secremain;   //????????

WriteAddr+=secremain; //?????·????    

    NumToWrite-=secremain; //×???(16??)??????

if(NumToWrite>(STM_SECTOR_SIZE/2))secremain=STM_SECTOR_SIZE/2;//???????????????????ê

else secremain=NumToWrite;//?????????????????ê??

}  

};

FLASH_Lock();//????

}

STMFLASH_Write(FLASH_SAVE_ADDR,(u16*)&power,1);//xiu

FLASH_SAVE_ADDR=FLASH_SAVE_ADDR +2;//4 
这样写入内部flash函数的调用，是不是可以不断写入内部flash啊，不管是哪一页，只要这个FLASH_SAVE_ADDR地址的值是多少，就能写入那个页地址里面啊。

我觉得你想问的是不是万一FLASH有写保护，是不是就不能这么操作了？
我也有点不明白，感觉应该先测试一下这些页是否有写保护，如果有的话，先失能写保护

正点原子

回复【楼主位】hwh123:
---------------------------------
是的。
WriteAddr+=secremain;              //?????·????
有个bug，改为：
WriteAddr+=secremain*2; //?????·????
