514 Block read is similar:
515 UsbCommand c = {CMD_MIFARE_CGETBLOCK, {params, blockNo, 0}};
516 We need to imitate that call with blockNo 0 to set a uid.
517
518 The get and set commands are handled in this file:
519 // Work with "magic Chinese" card
520 case CMD_MIFARE_CSETBLOCK:
521 MifareCSetBlock(c->arg[0], c->arg[1], c->d.asBytes);
522 break;
523 case CMD_MIFARE_CGETBLOCK:
524 MifareCGetBlock(c->arg[0], c->arg[1], c->d.asBytes);
525 break;
526
527 mfCSetUID provides example logic for UID set workflow:
528 -Read block0 from card in field with MifareCGetBlock()
529 -Configure new values without replacing reserved bytes
530 memcpy(block0, uid, 4); // Copy UID bytes from byte array
531 // Mifare UID BCC
532 block0[4] = block0[0]^block0[1]^block0[2]^block0[3]; // BCC on byte 5
533 Bytes 5-7 are reserved SAK and ATQA for mifare classic
534 -Use mfCSetBlock(0, block0, oldUID, wantWipe, MAGIC_SINGLE) to write it

771 OBJECTIVE
772 Listen and detect an external reader. Determine the best location
773 for the antenna.
774
775 INSTRUCTIONS:
776 Inside the ListenReaderField() function, there is two mode.
777 By default, when you call the function, you will enter mode 1.
778 If you press the PM3 button one time, you will enter mode 2.
779 If you press the PM3 button a second time, you will exit the function.
780
781 DESCRIPTION OF MODE 1:
782 This mode just listens for an external reader field and lights up green
783 for HF and/or red for LF. This is the original mode of the detectreader
784 function.
785
786 DESCRIPTION OF MODE 2:
787 This mode will visually represent, using the LEDs, the actual strength of the
788 current compared to the maximum current detected. Basically, once you know
789 what kind of external reader is present, it will help you spot the best location to place
790 your antenna. You will probably not get some good results if there is a LF and a HF reader
791 at the same place! :-)
