پاسخ : درست کردن هدر فایل LCD

با استفاده از مطالب اینترنت یک هدر فایل نوشتم اما متاسفانه کار نمیکه! نمیدونم مشکل دقیقا چی هست، کسی میتونه راهنمایی کنه؟

پاسخ : درست کردن هدر فایل LCD (حل شد)

بالاخره تونستم حلش کنم!!!
مشکل از این بود که من از پورت A برای EN و RS استفاده میکردم، پورت A آنالوگ است باید مقدار بیت های دو پین EN و RS را صفر در نظر میگرفتم تا پورت دیجیتال ست بشه!

وقتی که بیت ها دیجیتال ست نشده!

کد رو هم کمی تغییر دادم
