Issue with reading serial data

Anand_kumar:
Yeah Tom, I did go through the EM4095 document and came across signal RDY/CLK section. I'm using that signal to set the synchronization with the actual data but there was still an internal delay in the code with the use of digitalRead() function for 8usecs time period signals, I overcame it by using direct port manipulation, using (PINX & (1<<PBX)) function and ISR in Atmel studio instead of Arduino platform.

All I see in your Arduino code is ONE input?
What pins did you use for Signal and Clock?

I can understand the read time being the limitation.

Well NOT mentioning stuff has certainly not helped to clarify things. Perhaps it would have helped if you had started with something like "I have this device link which is normally used like blah blah blah but I want to use it like nah nah nah and this is the document that has the relevant details"

Indeed it is not too late for that sort of an introduction :)

I agree... :o

Tom... :slight_smile:
