لمن يمتلك الخبرة في لغة ال c المستعملة في الmicro controller أرجو المساعدة للضرورة القصوة و المستعجلة
هذا هو كود لتجربة التحكم . Single phase AC Motor speed controlle
وللأسف لم أتمكن من تحويلها الى لغة الhex لتفعيل التجربة , لذلك لمن يمتلك الخبرة أو القدرة على تحويله الى ال hex وارساله لي عن طريق الpdf وله جزيل الشكر .
وهذا هو الكود في لغة c
The complete operation is based on the software embedded in micro controller 89C2051. The software is written in C language. Different functions are used for different operations like ext1, ext0, delay and keydly etc. Here is the code with necessary comments which it self explains all above functions.
