477OBJECTIVE
478Listen and detect an external reader. Determine the best location
479for the antenna.
480
481INSTRUCTIONS:
482Inside the ListenReaderField() function, there is two mode.
483By default, when you call the function, you will enter mode 1.
484If you press the PM3 button one time, you will enter mode 2.
485If you press the PM3 button a second time, you will exit the function.
486
487DESCRIPTION OF MODE 1:
488This mode just listens for an external reader field and lights up green
489for HF and/or red for LF. This is the original mode of the detectreader
490function.
491
492DESCRIPTION OF MODE 2:
493This mode will visually represent, using the LEDs, the actual strength of the
494current compared to the maximum current detected. Basically, once you know
495what kind of external reader is present, it will help you spot the best location to place
496your antenna. You will probably not get some good results if there is a LF and a HF reader
497at the same place! :-)
