740 OBJECTIVE
741 Listen and detect an external reader. Determine the best location
742 for the antenna.
743
744 INSTRUCTIONS:
745 Inside the ListenReaderField() function, there is two mode.
746 By default, when you call the function, you will enter mode 1.
747 If you press the PM3 button one time, you will enter mode 2.
748 If you press the PM3 button a second time, you will exit the function.
749
750 DESCRIPTION OF MODE 1:
751 This mode just listens for an external reader field and lights up green
752 for HF and/or red for LF. This is the original mode of the detectreader
753 function.
754
755 DESCRIPTION OF MODE 2:
756 This mode will visually represent, using the LEDs, the actual strength of the
757 current compared to the maximum current detected. Basically, once you know
758 what kind of external reader is present, it will help you spot the best location to place
759 your antenna. You will probably not get some good results if there is a LF and a HF reader
760 at the same place! :-)
