/*
* `lf_tharexde` simulates hardcoded words/blocks, reads words of standard read
* mode of EM4x50 tags and stores them in internal flash.
* It requires RDV4 hardware (for flash and battery).
*
* On entering stand-alone mode, this module will start reading/record EM4x50 data.
* Every found / collected data will be written/appended to the logfile in flash
* as a text string.
*
* LEDs:
* - LED A: simulating
* - LED B: reading / record
* - LED C: writing to flash
* - LED D: unmounting/sync'ing flash (normally < 100ms)
*
* To retrieve log file from flash:
*
* 1. mem spiffs dump o lf_em4x50collect.log f lf_em4x50collect.log
* Copies log file from flash to your client.
*
* 2. exit the Proxmark3 client
*
* 3. more lf_tharexdecollect.log
*
* This module emits debug strings during normal operation -- so try it out in
* the lab connected to PM3 client before taking it into the field.
*
* To delete the log file from flash:
*
* 1. mem spiffs remove lf_tharexdecollect.log
