DS18B20驱动文法打开，麻烦各位大侠指点，先谢过啦

DS18b20的驱动程序用CreateFile()函数无法的开，请各位大侠指点

HANDLE hGio = CreateFile(L"GIO1:", GENERIC_READ | GENERIC_WRITE, 0, NULL, OPEN_EXISTING, 0, NULL);
   
if (hGio == INVALID_HANDLE_VALUE)
     {
   MessageBox(_T("Can not open GIO!"), _T("GIO"), MB_OK);
         return 0;
}

测温程序在裸机上测试功能正常，再次表示感谢

搞定了，啥问题？另外请将帖子修改为“已解决”

没有解决，只是测温程序在裸机上测试可以，但是驱动用CreateFile无法打开，麻烦大侠帮忙指点一下，谢谢

麻烦大侠们帮忙看看程序吧，帮忙找一下问题，谢谢

楼主解决问题没啊，我现在急需要DS18B20的驱动程序，不知楼主上面的驱动在哪有问题啊，求帮助。。。
