السلام عليكم ...
تحية لجميع الأساتذة و المشرفين و الأعضاء .
أقدم هذا الموضوع للمنتدى ... حتى تعم الفائدة للجميع إنشاء الله
هو عبارة على ساعة رقمية أربع خانات بالإضافة إلى وجود مخرج تحكم يمكن و صله إلى دارة منبه
كود البرنامج مكتوب كما فهمت بلغة البيزك
و أنا بصراحة لم أستطيع التعامل معه لعدم توفر برنامج لتحرير ملفات البيزك
كود:

أرجوا من الإخوة الذين عندهم إلمام بالبيزك إفادة الإخوة في المنتدى
من ناحية برامج التحرير و توليد ملف الهيكس لهذا المشروع
إنشاء الله سوف أضع ملف البروتوس لهذا المشروع في مشاركة لاحقة
بإنتظار الحصول على ملف الهيكس
