سلام من یه ال سی دی گرافیکی ts12864a رو بستم تو پورتئوس هم جواب داد اما متاسفانه ال سی دی در عمل فقط روشن میشه و هیچ چیزی نمایش نمیده پایه 3 و 18 رو هم وصل کردم به پایه های یه پتانسیومتر 0-50k پایه وسط پتانسیومترم دادم به گراند پتانسیومترم که میچرخونم فقط روشنایی کم و زیاد میشه و تو 50k هم کامل سیاه میشه
اینم برنامم :
