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