-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

+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! :-)
