+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! :-)
