افتراضي تعديل كود زيادة عداد الوقت Twitter FaceBook Google+


السلام عليكم
عندي مشروع عداد السرعة و حساب المسفات
اريد زيادة عرض الوقت و اشهر و السنة
و عرضها عللى السيفن سيغمون
باستعمال العداد ds1307

atmega16
Atmel Studio البرنامج مكتوب ب
هل من مساعدة لزيادة الكود المهتم ب الوقت و عرضه

السلام عليكم
اولا البرنامج غير مفهوم حاول ان ترفقه مع البروتيوس ليتم معالجته
ثانيا : حاول زيادة قيمة الكرستالة لكي تعطيك المطلوب
