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