我用的是128M的flash,由于单片机的数据存储器容量有限,所以我有4次读写完成1 page 的操作.下面这样写可以吗?
void Write10(void)
{
unsigned long int ByteCount;
unsigned int Transfer_Length;
unsigned int address;
unsigned char rank;
unsigned long Logical_Block_Address;
Logical_Block_Address=cbw.CBWCB[2]*0x1000000;
Logical_Block_Address+=cbw.CBWCB[3]*0x10000;
Logical_Block_Address+=cbw.CBWCB[4]*0x100;
Logical_Block_Address+=cbw.CBWCB[5];
Transfer_Length=cbw.CBWCB[7]*256+cbw.CBWCB[8];//the number of page(block).
while(Transfer_Length--)
{
for(rank=1;rank<=4;rank++)
{
ByteCount=512;address=0;
while(ByteCount>MAX_BULK_DATA_SIZE)
{
read_endpoint_buff(1,MAX_BULK_DATA_SIZE,&buffer[address]);
ByteCount-=MAX_BULK_DATA_SIZE;
address+=MAX_BULK_DATA_SIZE;
}
read_endpoint_buff(1,ByteCount,&buffer[address]);
Flash_page_program(rank,Logical_Block_Address,&buffer);
}
Flash_reflash();
Logical_Block_Address++;
}
Return_CSW(0,SUCCESS);
}
