748OBJECTIVE
749Listen and detect an external reader. Determine the best location
750for the antenna.
751
752INSTRUCTIONS:
753Inside the ListenReaderField() function, there is two mode.
754By default, when you call the function, you will enter mode 1.
755If you press the PM3 button one time, you will enter mode 2.
756If you press the PM3 button a second time, you will exit the function.
757
758DESCRIPTION OF MODE 1:
759This mode just listens for an external reader field and lights up green
760for HF and/or red for LF. This is the original mode of the detectreader
761function.
762
763DESCRIPTION OF MODE 2:
764This mode will visually represent, using the LEDs, the actual strength of the
765current compared to the maximum current detected. Basically, once you know
766what kind of external reader is present, it will help you spot the best location to place
767your antenna. You will probably not get some good results if there is a LF and a HF reader
768at the same place! :-)
