477 | OBJECTIVE | |
478 | Listen and detect an external reader. Determine the best location | |
479 | for the antenna. | |
480 | ||
481 | INSTRUCTIONS: | |
482 | Inside the ListenReaderField() function, there is two mode. | |
483 | By default, when you call the function, you will enter mode 1. | |
484 | If you press the PM3 button one time, you will enter mode 2. | |
485 | If you press the PM3 button a second time, you will exit the function. | |
486 | ||
487 | DESCRIPTION OF MODE 1: | |
488 | This mode just listens for an external reader field and lights up green | |
489 | for HF and/or red for LF. This is the original mode of the detectreader | |
490 | function. | |
491 | ||
492 | DESCRIPTION OF MODE 2: | |
493 | This mode will visually represent, using the LEDs, the actual strength of the | |
494 | current compared to the maximum current detected. Basically, once you know | |
495 | what kind of external reader is present, it will help you spot the best location to place | |
496 | your antenna. You will probably not get some good results if there is a LF and a HF reader | |
497 | at the same place! :-) | |
