482OBJECTIVE
483Listen and detect an external reader. Determine the best location
484for the antenna.
485
486INSTRUCTIONS:
487Inside the ListenReaderField() function, there is two mode.
488By default, when you call the function, you will enter mode 1.
489If you press the PM3 button one time, you will enter mode 2.
490If you press the PM3 button a second time, you will exit the function.
491
492DESCRIPTION OF MODE 1:
493This mode just listens for an external reader field and lights up green
494for HF and/or red for LF. This is the original mode of the detectreader
495function.
496
497DESCRIPTION OF MODE 2:
498This mode will visually represent, using the LEDs, the actual strength of the
499current compared to the maximum current detected. Basically, once you know
500what kind of external reader is present, it will help you spot the best location to place
501your antenna. You will probably not get some good results if there is a LF and a HF reader
502at the same place! :-)
