779OBJECTIVE
780Listen and detect an external reader. Determine the best location
781for the antenna.
782
783INSTRUCTIONS:
784Inside the ListenReaderField() function, there is two mode.
785By default, when you call the function, you will enter mode 1.
786If you press the PM3 button one time, you will enter mode 2.
787If you press the PM3 button a second time, you will exit the function.
788
789DESCRIPTION OF MODE 1:
790This mode just listens for an external reader field and lights up green
791for HF and/or red for LF. This is the original mode of the detectreader
792function.
793
794DESCRIPTION OF MODE 2:
795This mode will visually represent, using the LEDs, the actual strength of the
796current compared to the maximum current detected. Basically, once you know
797what kind of external reader is present, it will help you spot the best location to place
798your antenna. You will probably not get some good results if there is a LF and a HF reader
799at the same place! :-)
