Re: [AVR club] Re: interfacing prob in 8051 - Pablo Villaverde - May 12 18:03:41 2006
My suggestion is that you should at least try to find those resources on the
web for yourself. A lot is already available, but by looking at your message
you sound like "hey, please provide all the information for a school
project. I expect everything for free". No way!!!!
Work and learn, will you?

Pablo
