مشکل نمایش روی tft lcd با درایور ssd1963

[moslem1368]

با سلام
نمایشگر 7 اینچی AT070TN92 با برد درایور موجود در سایت توسط lpc1768 راه انداختم.
اما در نمایش تصاویر مشکل دارم. همونطور که در تصاویر زیر میبینید.

خودم فکر میکنم که مشکل از مقدار دهی رجیسترهای راه انداز سیستم باشه. اما مشکل رو نفهمیدم.
مقداردهی رجیسترهای راه انداز را هم در انتها گذاشتم

سلام بله مشکل از راه اندازی اولیه هستش
کد های زیر رو برای راه اندازیش امتحان کن

ممنون
ولی متاسفانه تغییری نکرد. در جایی خوندم که این مشکل در بقیه ی برد های سایت هم بوده و در واقع مشکل از بردهای تولیدیه.
شما تا خالا به این مشکل برخورد نکردید؟

به غیر از مشکل پر زدن تصویر این هدرفایل برای تغییر فونت تابعی نداره.
