489OBJECTIVE
490Listen and detect an external reader. Determine the best location
491for the antenna.
492
493INSTRUCTIONS:
494Inside the ListenReaderField() function, there is two mode.
495By default, when you call the function, you will enter mode 1.
496If you press the PM3 button one time, you will enter mode 2.
497If you press the PM3 button a second time, you will exit the function.
498
499DESCRIPTION OF MODE 1:
500This mode just listens for an external reader field and lights up green
501for HF and/or red for LF. This is the original mode of the detectreader
502function.
503
504DESCRIPTION OF MODE 2:
505This mode will visually represent, using the LEDs, the actual strength of the
506current compared to the maximum current detected. Basically, once you know
507what kind of external reader is present, it will help you spot the best location to place
508your antenna. You will probably not get some good results if there is a LF and a HF reader
509at the same place! :-)
