816OBJECTIVE
817Listen and detect an external reader. Determine the best location
818for the antenna.
819
820INSTRUCTIONS:
821Inside the ListenReaderField() function, there is two mode.
822By default, when you call the function, you will enter mode 1.
823If you press the PM3 button one time, you will enter mode 2.
824If you press the PM3 button a second time, you will exit the function.
825
826DESCRIPTION OF MODE 1:
827This mode just listens for an external reader field and lights up green
828for HF and/or red for LF. This is the original mode of the detectreader
829function.
830
831DESCRIPTION OF MODE 2:
832This mode will visually represent, using the LEDs, the actual strength of the
833current compared to the maximum current detected. Basically, once you know
834what kind of external reader is present, it will help you spot the best location to place
835your antenna. You will probably not get some good results if there is a LF and a HF reader
836at the same place! :-)
