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! :-)
