I could supply bit-banged routines or even hardware routines.

They are not going to help Mahesh with his particular problem.

On the other hand substituting some working bit-banged code can at least give the re-assurance that the devices are ok.

But Mahesh already knows that one CPU will work fine, and the other will not.


As to posting non-indented code: either young people have amazing visual coordination or they do it out of sheer bloody-mindedness.

I for one am not going to attempt to read it. I can copy it, re-format it and add comments if I choose. But why ? It is like inviting someone to a meal and scrambling up all the food. And then expect them to re-constitute it before eating.
