771OBJECTIVE
772Listen and detect an external reader. Determine the best location
773for the antenna.
774
775INSTRUCTIONS:
776Inside the ListenReaderField() function, there is two mode.
777By default, when you call the function, you will enter mode 1.
778If you press the PM3 button one time, you will enter mode 2.
779If you press the PM3 button a second time, you will exit the function.
780
781DESCRIPTION OF MODE 1:
782This mode just listens for an external reader field and lights up green
783for HF and/or red for LF. This is the original mode of the detectreader
784function.
785
786DESCRIPTION OF MODE 2:
787This mode will visually represent, using the LEDs, the actual strength of the
788current compared to the maximum current detected. Basically, once you know
789what kind of external reader is present, it will help you spot the best location to place
790your antenna. You will probably not get some good results if there is a LF and a HF reader
791at the same place! :-)
