479 | OBJECTIVE | |
480 | Listen and detect an external reader. Determine the best location | |
481 | for the antenna. | |
482 | ||
483 | INSTRUCTIONS: | |
484 | Inside the ListenReaderField() function, there is two mode. | |
485 | By default, when you call the function, you will enter mode 1. | |
486 | If you press the PM3 button one time, you will enter mode 2. | |
487 | If you press the PM3 button a second time, you will exit the function. | |
488 | ||
489 | DESCRIPTION OF MODE 1: | |
490 | This mode just listens for an external reader field and lights up green | |
491 | for HF and/or red for LF. This is the original mode of the detectreader | |
492 | function. | |
493 | ||
494 | DESCRIPTION OF MODE 2: | |
495 | This mode will visually represent, using the LEDs, the actual strength of the | |
496 | current compared to the maximum current detected. Basically, once you know | |
497 | what kind of external reader is present, it will help you spot the best location to place | |
