    ساخت یک فایل سیستم

    سلام
    من باید یک درایور برای usb طراحی کنم و می خوام بدونم فایلهای .sys را چطوری می سازند(کامپایل می کنند)
    we are here,it must be done

    پاسخ : ساخت یک فایل سیستم

    سلام
    خوب چون کسی جواب نداد من خودم جوابما می دم
    برای درایورنویسی شما به یک کامپایلر visual c++ و برنامه driver development kit(DDK) نیاز دارید که ddk98 را می تونید رایگان دانلودوDDK XP را خریداری کنید که خیلی کامله و اینجا شرکتای معتبر دارند
    برای ساخت فایل سیستم شما بایدسه تا فایل src,makefile,source code داشته باشید
    bye :biggrin:

      سلام.
      ممنون اط توضیحت.
      میشه یه نمونه کد هم بگذاری؟
      منم دنبال کار با USB هستم ولی چیزی پیدا نکردم.
      ممنون.
