GBK转unicode不成功，跪求大神帮忙。

ElecUtopia

我把cc936.c里面的数组 转为unigbk.bin,直接放在SD卡，不经过外部FLASH储存。
其他函数经过验证，没发现问题，只是这里转码不成功，我也不知道是哪里错了。好人一生平安。

[mw_shl_code=c,true]WCHAR ff_convert ( /* Converted code, 0 means conversion error */ WCHAR src, /* Character code to be converted */ UINT dir /* 0: Unicode to OEMCP, 1: OEMCP to Unicode */ ) { WCHAR t[2]; WCHAR c; u8 buf[512]; u32 i, li, hi; u16 n; u32 gbk2uni_offset=0; u32 temp1=0; u32 temp2=0; u16 x=0; if (src < 0x80)c = src;//ASCII,直接不用转换. else { if(dir) //GBK 2 UNICODE { gbk2uni_offset=UGBKSIZE/2; }else //UNICODE 2 GBK { gbk2uni_offset=0; } /* Unicode to OEMCP */ hi=UGBKSIZE/2;//对半开. hi =hi / 4 - 1; li = 0; for (n = 16; n; n--) { i = li + (hi - li) / 2; temp1=i*4+gbk2uni_offset; temp2=temp1>>9;//相对于UGBKADDR偏移的扇区数 temp1=temp1-(temp2<<9);//在目标扇区偏移的位置 // SD_ReadBlocks(UGBKADDR+temp2,buf);//读取目标扇区(512B)的数据 SD_ReadDisk(buf,UGBKADDR+temp2,1); t[0]=(u16)buf[temp1]+(u16)(buf[temp1+1]<<8); t[1]=(u16)buf[temp1+2]+(u16)(buf[temp1+3]<<8); LCD_ShowNum(50,0+x,(u32)t[1],6,16);x+=16; if (src == t[0]) break; if (src > t[0])li = i; else hi = i; } c = n ? t[1] : 0; } return c; } [/mw_shl_code]

顶上去。顶上去。顶上去。

参考我们的例程.
我们的fatfs例程,就是这么做的,只是存放在SPI FLASH而已.你放SD卡.

你放在FLASH，不适合我用啊，我改成直接放在SD卡，参考你的修改了我的程序，但是不行，二分法16阶 最后求得的数 不对。
工程已上传，哪位大哥能帮我发现问题？

外部SPI Flash/SD卡没区别，跟你文件放硬盘或U盘一样。

我知道啊，但是程序不成功啊~~~ff_convert()写不好。

放到外部卡的回复【7楼】正点原子:
---------------------------------
放到外部SD卡的时候，我可以读出长文件名，比如歌曲“世界你好我好大家好.mp3”，但是我把获得的“世界你好我好大家好.mp3”这个字符串地址用文件系统打开，却报路径不对。
必须是“世界你好~1.MP3”才对。
~~！！
请问下原子哥，我用原来的CC936（带有数组）的就正确，但是移植到SD卡的就不对了
为什么啊
