حرکت متن یاتصویر روی glcd

[amin-zareian]

سلام بااستفاده کتابخانه موجود درسایت، glcd ks0108رو راه اندازی کردیم
حال می خواهیم تابعی به این کتابخانه اضافه کنیم که با آن بتوانیم تصاویریا نوشته هارا به حرکت درآوریم
مثلا تصویری روی glcdقرار گرفته می خواهیم با شیفت تصویر موجود، تصویر جدیدرا وارد کنیم راهنمایی کنید

این کتابخانه مورد استفاده قرار گرفته
