خودتون برد درایور USB ماژول های NRF24L01 بسازین

[sepehr63]

چند وقت پیش قبل از اینکه برد درایور USB ماژول های NRF24L01 سایت ببینم به فکر ساختش بودم که اونو ساختم و بعد از دست کاری
کد برنامه نتیجه این شد :mrgreen: کسی خواست دانلود کنه بسازه . برای مبدل USB به سریال از یک میکرو MEGA8 استفاده کردم
و برای درایو NRF هم از یک مگا 8 دیگه . با این ماژول هم میتونید بفرستین و هم بگیرین فقط دیتا هایی که توی محیط ترمینال مینویسید داخل پرانتز باشه
مثلا (1234)
قسمت usb اون هم روی برد در آوردم که حسابی ارزون بشه . فقط پشت قسمت فیش usb 4 تا ترک هست که روی اون سیم لحیم بکشید تا کلفت بشه لغ نخوره

برای میکرو اول هم که به usb متصل میشه توی گوگل usbpio سرچ کنید درایور و فایل هگز اون هست :mrgreen:
