## [unreleased][unreleased]
### Added
- ISO14443a stand-alone operation with ARM CFLAG="WITH_ISO14443a_StandAlone". This code can read & emulate two banks of 14a tag UIDs and write to "magic" cards (Craig Young)
### Added
- AWID26 command context added as 'lf awid' containing realtime demodulation as well as cloning/simulation based on tag numbers (Craig Young)
### Changed
- EPA functions (`hf epa`) now support both ISO 14443-A and 14443-B cards (frederikmoellers)

/* Example from client/mifarehost.c for commanding a block write for "magic Chinese" cards:

memcpy(c.d.asBytes, data, 16);

Block read is similar:
UsbCommand c = {CMD_MIFARE_CGETBLOCK, {params, 0, blockNo}};
We need to imitate that call with blockNo 0 to set a uid.
The get and set commands are handled in this file:
// Work with "magic Chinese" card

MifareCSetBlock(c->arg[0], c->arg[1], c->arg[2], c->d.asBytes);

MifareCGetBlock(c->arg[0], c->arg[1], c->arg[2], c->d.asBytes);
//
break;
mfCSetUID provides example logic for UID set workflow:
-Read block0 from card in field with MifareCGetBlock()
-Configure new values without replacing reserved bytes
memcpy(block0, uid, 4); // Copy UID bytes from byte array
// Mifare UID BCC
block0[4] = block0[0]^block0[1]^block0[2]^block0[3]; // BCC on byte 5
Bytes 5-7 are reserved SAK and ATQA for mifare classic
-Use mfCSetBlock(0, block0, oldUID, wantWipe, CSETBLOCK_SINGLE_OPER) to write it
