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