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