757 OBJECTIVE
758 Listen and detect an external reader. Determine the best location
759 for the antenna.
760
761 INSTRUCTIONS:
762 Inside the ListenReaderField() function, there is two mode.
763 By default, when you call the function, you will enter mode 1.
764 If you press the PM3 button one time, you will enter mode 2.
765 If you press the PM3 button a second time, you will exit the function.
766
767 DESCRIPTION OF MODE 1:
768 This mode just listens for an external reader field and lights up green
769 for HF and/or red for LF. This is the original mode of the detectreader
770 function.
771
772 DESCRIPTION OF MODE 2:
773 This mode will visually represent, using the LEDs, the actual strength of the
774 current compared to the maximum current detected. Basically, once you know
775 what kind of external reader is present, it will help you spot the best location to place
776 your antenna. You will probably not get some good results if there is a LF and a HF reader
777 at the same place! :-)
