723 | OBJECTIVE | |
724 | Listen and detect an external reader. Determine the best location | |
725 | for the antenna. | |
726 | ||
727 | INSTRUCTIONS: | |
728 | Inside the ListenReaderField() function, there is two mode. | |
729 | By default, when you call the function, you will enter mode 1. | |
730 | If you press the PM3 button one time, you will enter mode 2. | |
731 | If you press the PM3 button a second time, you will exit the function. | |
732 | ||
733 | DESCRIPTION OF MODE 1: | |
734 | This mode just listens for an external reader field and lights up green | |
735 | for HF and/or red for LF. This is the original mode of the detectreader | |
736 | function. | |
737 | ||
738 | DESCRIPTION OF MODE 2: | |
739 | This mode will visually represent, using the LEDs, the actual strength of the | |
740 | current compared to the maximum current detected. Basically, once you know | |
741 | what kind of external reader is present, it will help you spot the best location to place | |
742 | your antenna. You will probably not get some good results if there is a LF and a HF reader | |
743 | at the same place! :-) | |
