469 OBJECTIVE
470 Listen and detect an external reader. Determine the best location
471 for the antenna.
472
473 INSTRUCTIONS:
474 Inside the ListenReaderField() function, there is two mode.
475 By default, when you call the function, you will enter mode 1.
476 If you press the PM3 button one time, you will enter mode 2.
477 If you press the PM3 button a second time, you will exit the function.
478
479 DESCRIPTION OF MODE 1:
480 This mode just listens for an external reader field and lights up green
481 for HF and/or red for LF. This is the original mode of the detectreader
482 function.
483
484 DESCRIPTION OF MODE 2:
485 This mode will visually represent, using the LEDs, the actual strength of the
486 current compared to the maximum current detected. Basically, once you know
487 what kind of external reader is present, it will help you spot the best location to place
488 your antenna. You will probably not get some good results if there is a LF and a HF reader
489 at the same place! :-)
