Sure, Like I said before, I didn't post much about the module and it's datasheet because the current module I'm working is a small part of it and my aim is more of a generalized topic rather than the module information. Anyways, for your reference here is the link to the module,
http://www.emmicroelectronic.com/products/rf-identification-security/rfid-tools-support/emdb409
Once you open it then you can see different sections of it, hardware design, firmware description, so on. The firmware is in C++ and it can be read using Atmel Studio but its way to complicated for my understanding as I'm new to this. I'm trying to learn it and eventually program in atmel studio but as of now I need to read the serial data at every 8us, that I get from the module and store in a buffer for further data processing.
I have attached the firmware section of the module if you need it for reference(you might need atmel studio to run it). Also I have attached the schematics of the hardware, you can see Demod_out pin in the schematics. I use that pin to read the serial data that I need to read and store at every 8usec for further data processing.
Please let me know if you need any more information. Thank you.
