我用了GUI_DrawStreamedBitmapExAuto(_GetDataEx,(void *)&BitBMPBinary,0,0);
还加了GUI_BMP_GetXSizeEx(_GetDataEx, (void *)&BitBMPBinary);
GUI_BMP_GetYSizeEx(_GetDataEx, (void *)&BitBMPBinary);
执行第一次，NumBytesReq = 0x1A, off = 0x00
执行第二次，NumBytesReq = 0x1A, off = 0x00
执行第三次，NumBytesReq = 0x10, off = 0x00
执行第四次，NumBytesReq = 0x25800, off = 0x10 这个整个文件的长度
我每次只读一个sector=4096B, 然后它就不来第5次了
