新建main.c文件，这里是带参数的，主要是方便批处理，是另有用途。
?
#include
#include "bin2hex.h"
int main(int argc, char *argv[])
{
RESULT_STATUS res;
if (argc != 3)
{
printf("input para doesn't match\r\n");
return -1;
}
res = BinFile2HexFile(argv[1], argv[2]);
switch (res)
{
case RES_OK:
printf("hex file to bin file success!\r\n");
return -1;
case RES_BIN_FILE_NOT_EXIST:
printf("bin file doesn't exist!\r\n");
return -1;
case RES_HEX_FILE_PATH_ERROR:
printf("hex file path is error, please check it!\r\n");
return -1;
}
return 0;
}

就三个源文件，编译生成bin2hex.c文件。
下面描述下用法:
把bin2hex.c文件拷贝到c盘根目录下，再拷贝一个需要转换的bin文件，这里我就拷贝了一个hwb.bin文件。然后点击菜单开始->运行->输入cmd->进入dos窗口->调整当前目录为c:，这个如果不知道的可以百度一下，无法就是就是命令cd.
最后输入命令:bin2hex hwb.bin hwb.hex，输入后，可以看到提示说转换成功，大家再检查下是否有一个hex文件，本文的代码支持大于64K，大家把转换后的hex下载到单片机上运行试试看。
