Majid, take a deeper look, the interrupt receiving routine in the library is the one I've shared. Once you include the 'serial_hw_int_cts' library in your program the interrupt is already included so you need just to read the received data from the buffer. The difference between the library and posted routine is that the last one does not use any circular buffer which may be intimidating for a new user... You have to understand by yourself and write a test program for communication only. After it works, integrate it in your program as you need. Do not try to make it working in a single step. Good luck!
