برنامه arduino برای نمایش تاریخ و ساعت روی 7segment و ماژول 6 رقمی max7219

[حمید حمید]

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

سلام مدتی از تاپیک شما گذشته.داشتم دنبال کتابخانه تبدیل تاریخ شمسی میگشتم که به اینجا رسیدم راستش چند کتابخانه پیدا کردم وظاهرا درست کار میکنن ولی در عمل ایراداتی دارند شما کتابخانه را ضمیمه نکردی ولی اگر یکی از آنها باشد که تست کردم در تبدیل تاریخ 19/2/2017 که میشود 1/12/1395 وحتما چند تاریخ دیگر ایراد دارد اگر توانستید کتابخانه دقیقی بای تبدیل شمسی میلادی پیدا کنید لطفا بنویسید اینجا یا اطلاع دهید بیشتر کتابخانه ها در تبدیل تاریخ نوشته شده و تاریخهایی مشابه 9/ژاونیه/2025 و 20/10/1403 وتاریخهای در این رنج یا کبیسه ها ایراد دارند
