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