Hi

Thankyou peter, you are very co-operative always.

My problem is that I am living in Desert. Not actually as our city Dubai is now known as modern business city, but here is no technological development. Locally too much money people have so they rather try to outsource everything. So locally it is very hard for me to find some good chips. Here are some stores selling industrial electronics components but first they do not have latest stuff, secondly un-justifiable prices.

Therefore I have to source all parts from India/Pakistan or from US/Europe/Fareast through net.

I will appreciate if you can name some A/D converter where you have your own experience.

I will also prefer to use 89C2051 or 89C52 as I do have programmer for them. If I choose different uP then I have to arrange programmer for them, so for the time being it is my handicape.

Thanks

Rauf
