774OBJECTIVE
775Listen and detect an external reader. Determine the best location
776for the antenna.
777
778INSTRUCTIONS:
779Inside the ListenReaderField() function, there is two mode.
780By default, when you call the function, you will enter mode 1.
781If you press the PM3 button one time, you will enter mode 2.
782If you press the PM3 button a second time, you will exit the function.
783
784DESCRIPTION OF MODE 1:
785This mode just listens for an external reader field and lights up green
786for HF and/or red for LF. This is the original mode of the detectreader
787function.
788
789DESCRIPTION OF MODE 2:
790This mode will visually represent, using the LEDs, the actual strength of the
791current compared to the maximum current detected. Basically, once you know
792what kind of external reader is present, it will help you spot the best location to place
793your antenna. You will probably not get some good results if there is a LF and a HF reader
794at the same place! :-)
