在单片机程序里面有时候要将 bin 转换为 hex 写下 mark 一下

#include "stdio.h"
typedef unsigned char BYTE;
typedef unsigned long DWORD;
int main(int argc, char* argv[])
{
   char *pt, buf[256] = ":", filename[256];
   BYTE *pRomData;
   int i, filelen, addr;
   BYTE sum;
   FILE *fp;
   if (argc < 3)
   {
       printf("no parameter!");
       return 1;
   }
   for (i = 0; argv[1][i] != '.'; i++)   filename[i] = argv[1][i];
   filename[i++] = '.'; filename[i++] = 'h'; filename[i++] = 'e'; filename[i++] = 'x'; filename[i++] = 0;

sscanf(argv[2], "%x", &addr);

   fp = fopen(argv[1], "rb");
   if (fp == NULL)
   {
       printf("no file!");
       return 1;
   }
   fseek(fp, 0, SEEK_END);
   filelen = ftell(fp);
   printf("file len:%d\r\n", filelen);
   pRomData = new BYTE[filelen];
   fseek(fp, 0, SEEK_SET);
   fread(pRomData, 1, filelen, fp);
   fclose(fp);

   fp = fopen(filename, "wb");
   pt = buf + 1;
   sum = 0x100 - 02 - 04 - (addr / 0x1000000) - ((addr & 0xFF0000) / 0x10000);
   pt += sprintf(pt, "02000004%04X%02X\r\n", addr / 0x10000, sum);
   fwrite(buf, 1, (DWORD)pt - (DWORD)buf, fp);
   for (addr = 0; addr<filelen;)
   {
       DWORD cnt, i;
       pt = buf + 1;
       cnt = filelen - addr; if (cnt>0x20)   cnt = 0x20; pt += sprintf(pt, "%02X%04X00", cnt, addr); sum = (BYTE)(cnt + (addr / 0x100) + (addr & 0xFF));
       for (i = 0; i<cnt; i++)
       {
           pt += sprintf(pt, "%02X", pRomData[addr]); sum += pRomData[addr];
           ++addr;
       }
       sum = 0x100 - sum;
       pt += sprintf(pt, "%02X\r\n", sum);
       fwrite(buf, 1, (DWORD)pt - (DWORD)buf, fp);
   }
   pt = buf + 1;
   pt += sprintf(pt, "00000001FF\r\n");
   fwrite(buf, 1, (DWORD)pt - (DWORD)buf, fp);
   fclose(fp);
}
