+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! :-)
