سلام دوستان
من یک کتابخونه دارم که با اون ال سی دی کاراکتری رو برای سری f1راه اندازی کردم ولی برا سری f4که میخوام استفاده کنم کامپایلر ارور میده. کسی میتونه این کتابخونه رو تبدیل کنه؟
فک کنم به نحوه ورودی و خروجی کردن پایه ها گیر میده. منم تازه با ارم شروع کردم کار کردن اینا رو بلد نیستم تبدیل کنم.
ممنون میشم راهنمایی کنید
فایل دانلود کتابخونه:
به این قسمت ها ارور میده:
اینم کل کد کتابخونه:
