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