بسم الله
با سلام و عرض تبریک به مناسبت میلاد بهترین و مهربانترین و اشرف انسانها پیامبر خاتم محمد مصطفی صل الله علیه و اله وسلم
دو برنامه جدا هست از اساتیدی که براشون امکان داره میخواهم که این 2 برنامه را باهم تلفیق کنن
به نحوی که همزمان ساعت روی 4 عدد 7segment ،و نمایش تاریخ روی ماژول 6 رقمی max7219 قابل نمایش باشد.
در ضمن این برنامه تاریخ میلادی و شمسی را بدون خطا نشون میده اما اگه گسی میتونه تاریخ قمری هم بهش اضافه کنه کاملتر میشه.
قطعات مور استفاده:
1-ESP32
2-چهار عدد 7segment آند مشترک
3- مازول 6رقمی max7219
4- ماژول ds3231
5- شیفت رجیستر 74HC595
..
1- نمایش ساعت روی 4 عدد 7segment آند مشترک
2- نمایش تاریخ میلادی و شمسی و ساعت روی ماژول 6 رقمی با چیپ max7219
