hi, after a long gap i again entered into 8051 programming profession .before i worked with uv2 and uv3. but now uv4,uv5 had been introduced.whether these older version are in use?what are the major difference between uv3 ,uv5? please suggest me which keil software can be used for mini projects?
As with anything else, just download the current version.
Study the documentation; practice with the examples ...
You'll see what's different; most of it will be familiar.
the only thing that may happen with using a newer version is that you may find that the code (NOT the compiler) has a bug that somehow slipped through with the other version. With sloppy code it is not unusual that a timing error (bad coding) wil show with some version and not another. as a related example I recall someone posting "ny code works when the debug printf is enabled, but not when it is disabled UGH.

The older programmers amongst us might know this as a Heisenbug:

Andrew Neil, do you see how other people have submitted helpful comments, unlike you. You seem to think you are a coding God but never give particularly helpful replies. Why bother at all?
