+OBJECTIVE\r
+Listen and detect an external reader. Determine the best location\r
+for the antenna.\r
+\r
+INSTRUCTIONS:\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
+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
+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
