Yeah true if we look at the RFID module level then the code I'm working out doesn't make much sense but the code I'm working right now is one of the important block for that project and I didn't mention much about the project since the beginning because it will mislead the topic.
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
