838 OBJECTIVE
839 Listen and detect an external reader. Determine the best location
840 for the antenna.
841
842 INSTRUCTIONS:
843 Inside the ListenReaderField() function, there is two mode.
844 By default, when you call the function, you will enter mode 1.
845 If you press the PM3 button one time, you will enter mode 2.
846 If you press the PM3 button a second time, you will exit the function.
847
848 DESCRIPTION OF MODE 1:
849 This mode just listens for an external reader field and lights up green
850 for HF and/or red for LF. This is the original mode of the detectreader
851 function.
852
853 DESCRIPTION OF MODE 2:
854 This mode will visually represent, using the LEDs, the actual strength of the
855 current compared to the maximum current detected. Basically, once you know
856 what kind of external reader is present, it will help you spot the best location to place
857 your antenna. You will probably not get some good results if there is a LF and a HF reader
858 at the same place! :-)
