816 OBJECTIVE
817 Listen and detect an external reader. Determine the best location
818 for the antenna.
819
820 INSTRUCTIONS:
821 Inside the ListenReaderField() function, there is two mode.
822 By default, when you call the function, you will enter mode 1.
823 If you press the PM3 button one time, you will enter mode 2.
824 If you press the PM3 button a second time, you will exit the function.
825
826 DESCRIPTION OF MODE 1:
827 This mode just listens for an external reader field and lights up green
828 for HF and/or red for LF. This is the original mode of the detectreader
829 function.
830
831 DESCRIPTION OF MODE 2:
832 This mode will visually represent, using the LEDs, the actual strength of the
833 current compared to the maximum current detected. Basically, once you know
834 what kind of external reader is present, it will help you spot the best location to place
835 your antenna. You will probably not get some good results if there is a LF and a HF reader
836 at the same place! :-)
