752 | OBJECTIVE | |
753 | Listen and detect an external reader. Determine the best location | |
754 | for the antenna. | |
755 | ||
756 | INSTRUCTIONS: | |
757 | Inside the ListenReaderField() function, there is two mode. | |
758 | By default, when you call the function, you will enter mode 1. | |
759 | If you press the PM3 button one time, you will enter mode 2. | |
760 | If you press the PM3 button a second time, you will exit the function. | |
761 | ||
762 | DESCRIPTION OF MODE 1: | |
763 | This mode just listens for an external reader field and lights up green | |
764 | for HF and/or red for LF. This is the original mode of the detectreader | |
765 | function. | |
766 | ||
767 | DESCRIPTION OF MODE 2: | |
768 | This mode will visually represent, using the LEDs, the actual strength of the | |
769 | current compared to the maximum current detected. Basically, once you know | |
770 | what kind of external reader is present, it will help you spot the best location to place | |
771 | your antenna. You will probably not get some good results if there is a LF and a HF reader | |
772 | at the same place! :-) | |
