834 OBJECTIVE
835 Listen and detect an external reader. Determine the best location
836 for the antenna.
837
838 INSTRUCTIONS:
839 Inside the ListenReaderField() function, there is two mode.
840 By default, when you call the function, you will enter mode 1.
841 If you press the PM3 button one time, you will enter mode 2.
842 If you press the PM3 button a second time, you will exit the function.
843
844 DESCRIPTION OF MODE 1:
845 This mode just listens for an external reader field and lights up green
846 for HF and/or red for LF. This is the original mode of the detectreader
847 function.
848
849 DESCRIPTION OF MODE 2:
850 This mode will visually represent, using the LEDs, the actual strength of the
851 current compared to the maximum current detected. Basically, once you know
852 what kind of external reader is present, it will help you spot the best location to place
853 your antenna. You will probably not get some good results if there is a LF and a HF reader
854 at the same place! :-)
