lpc2292 uart interrupt

Started by kooroshhajiani April 29, 2007
The problem here is that jayasooriah is the one with the
closed mind who likes to turn everything into a slinging
match whenever his (presumably deliberately) misleading
statements are questioned.

By misusing the processors in a naive way he seems to
encounter problems which do not occur when things are
done correctly. And then he claims to be the only expert
on fixing those problems.

I assume that he is trying to promote himself as a
consultant for these processors (either on his own or
on behalf of his employer). But his behavior creates
a bad impression of both himself and the University
of New South Wales.

Jaya,

You're clearly not reading what I'm writing, but repeating your own
point over and over. Enough!

Danish,

As off-topic as it is, I think the above is an excellent example of
personal attack as it is full of (self gratifying and) gratuitous
insults against the person making the point while making little or not
contribution to the technical discussion.

Kind regards,

Jaya

The post was, and is still, labeled "off topic".
It also simply stated facts that all readers can see for themselves.
If that is percieved as a "personal attack" then there is probably
some problem at the perception end.

Whatever!
