سلام دوستان من یک SRF05 دارم وهدفم اینه که فاصله رو اندازه بگیره و روی LCD بنویسه حالا من یک کدی نوشتم اما درست کار نمی کنه در واقع هیچ عددی نمی نویسه!
برنامه هم اینطوری کار می کنه که اول میام وtrig رو 1 می کنم بعد echo 1 میشه در این لحظه چون echo رو به پایه اینتراپت دادم یک اینتراپت تولید می شه!در اینتراپت میام ویک counter رو صفر می کنم که مربوط به تایمر هست و در اینتراپت تایمر این counter رو با 1 جمع می کنم آخرشم که زمان رو با ضرب کردن counter در عدد مناسب به زمان تبدیل می کنم و روی LCD می نویسمش!
***دوستان خواهشا اشکال کد من رو پیداا کنید!می دونم که کد آمادش همه جا هست.
ممنون
