با سلام خدمت اساتید با توجه به اینکه من بعد از مدتها اومدم سراغ VB برای یک پرژه ساده که قصد دارم یک سری LED رو توسط نرم افزار گرافیکی در PC کنترل کنم از اونجایی که سوالات و مشکلات زیادی در برنامه نویسی دارم گفتم یه تایپیک ایجاد کنم دوستان هر سوال ساده ایی که دارند ایجا مطرح کنند
سوال خودم رو به صورت تصویری بیان میکنم
من برای کنترل این led ها یک سری چک باکس ایجاد کردم و آرایه a رو با 24 عضو به عنوان گیرنده اطلاعات معرفی کردم که تیک خوردن چک باکس رو معادل یک . تیک نخوردنش رو معادل صفر در نظر بگیره با توجه به پروتوکل ارتباطی با میکرو کنترلر هر بار میتونم یک بایت اطلاعات اریال کنم یا در صورت زیاد بودن طول اطلاعات طی چند بایت این کار رو انجام بدم
با توه به اینکه من 24 عدد LED جهت کنترل دارم و میکرو کنترلرم Atmega16 هست و سه تا از پزتاش به صورت کامل جهت کنترل این LED ها اشغال میشه من a(0) تا a(7) رو به کنترل پورت یک میخوام اختصاص بدم و همینطور ادامه دار برای بقیه پورتها همین روش رو به کار ببرم ولی الآن نمیدونم چطور باید اعداد این ماتریکس رو استخراج کنم و به صورت بایت ارسال کنم تابع ارسالم همونطور که در کد مشخصه bufferout() هست که از نوع بایته
