باز هم ال سی دی گرافیکی ts12864a

[ajajoom]

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 :

لطفا راهنمایی کنید

[do...loop]

سلام دوست عزيز اگه السيدي تو روي برد بورد بستي ممكنه جواب نده
منم همين مشكل رو داشتم دوستي راهنمائيم كرد و گفت مدارت رو روي فيبر ببند درست ميشه

[navid32]

وقتی با تست اتصالی تست میگیریم رو بردبورد همه اتصالا بر قراره اما فقط ال سی دی روشن میمونه هیج عکس العملی نداریم :(
