482 | OBJECTIVE | |
483 | Listen and detect an external reader. Determine the best location | |
484 | for the antenna. | |
485 | ||
486 | INSTRUCTIONS: | |
487 | Inside the ListenReaderField() function, there is two mode. | |
488 | By default, when you call the function, you will enter mode 1. | |
489 | If you press the PM3 button one time, you will enter mode 2. | |
490 | If you press the PM3 button a second time, you will exit the function. | |
491 | ||
492 | DESCRIPTION OF MODE 1: | |
493 | This mode just listens for an external reader field and lights up green | |
494 | for HF and/or red for LF. This is the original mode of the detectreader | |
495 | function. | |
496 | ||
497 | DESCRIPTION OF MODE 2: | |
498 | This mode will visually represent, using the LEDs, the actual strength of the | |
499 | current compared to the maximum current detected. Basically, once you know | |
500 | what kind of external reader is present, it will help you spot the best location to place | |
501 | your antenna. You will probably not get some good results if there is a LF and a HF reader | |
502 | at the same place! :-) | |
