برنامه بالا قراره که یه خروجی مثلا موتور رو خاموش و روشن کنه و توسط یه سنسور که دورسنج یا دما می تونه باشه ، مقدار رو دریافت و در پورت spi قرار بده ...
اساتید لطف می کنید بررسی کنید که این برنامه درسته و آیا کار می کنه ؟ من برد آرم رو ندارم .
خواستم کل فایل رو هم که فشرده کرده بودم رو بذارم ، اما خطا گرفت !
