767OBJECTIVE
768Listen and detect an external reader. Determine the best location
769for the antenna.
770
771INSTRUCTIONS:
772Inside the ListenReaderField() function, there is two mode.
773By default, when you call the function, you will enter mode 1.
774If you press the PM3 button one time, you will enter mode 2.
775If you press the PM3 button a second time, you will exit the function.
776
777DESCRIPTION OF MODE 1:
778This mode just listens for an external reader field and lights up green
779for HF and/or red for LF. This is the original mode of the detectreader
780function.
781
782DESCRIPTION OF MODE 2:
783This mode will visually represent, using the LEDs, the actual strength of the
784current compared to the maximum current detected. Basically, once you know
785what kind of external reader is present, it will help you spot the best location to place
786your antenna. You will probably not get some good results if there is a LF and a HF reader
787at the same place! :-)
