Listen and detect an external reader. Determine the best location\r
for the antenna.\r

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