384OBJECTIVE\r
385Listen and detect an external reader. Determine the best location\r
386for the antenna.\r
387\r
388INSTRUCTIONS:\r
389Inside the ListenReaderField() function, there is two mode.\r
390By default, when you call the function, you will enter mode 1.\r
391If you press the PM3 button one time, you will enter mode 2.\r
392If you press the PM3 button a second time, you will exit the function.\r
393\r
394DESCRIPTION OF MODE 1:\r
395This mode just listens for an external reader field and lights up green\r
396for HF and/or red for LF. This is the original mode of the detectreader\r
397function.\r
398\r
399DESCRIPTION OF MODE 2:\r
400This mode will visually represent, using the LEDs, the actual strength of the\r
401current compared to the maximum current detected. Basically, once you know\r
402what kind of external reader is present, it will help you spot the best location to place\r
403your antenna. You will probably not get some good results if there is a LF and a HF reader\r
404at the same place! :-)\r
