772 OBJECTIVE
773 Listen and detect an external reader. Determine the best location
774 for the antenna.
775
776 INSTRUCTIONS:
777 Inside the ListenReaderField() function, there is two mode.
778 By default, when you call the function, you will enter mode 1.
779 If you press the PM3 button one time, you will enter mode 2.
780 If you press the PM3 button a second time, you will exit the function.
781
782 DESCRIPTION OF MODE 1:
783 This mode just listens for an external reader field and lights up green
784 for HF and/or red for LF. This is the original mode of the detectreader
785 function.
786
787 DESCRIPTION OF MODE 2:
788 This mode will visually represent, using the LEDs, the actual strength of the
789 current compared to the maximum current detected. Basically, once you know
790 what kind of external reader is present, it will help you spot the best location to place
791 your antenna. You will probably not get some good results if there is a LF and a HF reader
792 at the same place! :-)
