Hi all,

I want to know what are the usual/exact values of the (pull-up ? ) resistors and capacitors used in the interface. I read somewhere that there should be only a particular set of values of the resisitors and capactors through which data transfer is possible !!


Any ideas would be appreciated.



Thanks in advance, Amit.
