* It requires RDV4 hardware (for flash and battery).
*
* On entering stand-alone mode, this module will start simulating.
* Data is read from bin dump file uploaded to flash memory (hf_mfcsim_dump.bin).
* Data is read from bin dump file uploaded to flash memory (hf_mfcsim_dump_xx.bin).
* Only support mifare classic 1k
*
* LEDs:
* - LED A: initializing
* - LED B: simulating
* - LED C blinking: data transmiting
*
* To upload input file (eml format) to flash:
* - mem spiffs upload -s <filename> -d hf_mfcsim_dump.bin
* - mem spiffs upload -s <filename> -d hf_mfcsim_dump_xx.bin (Notes: xx is form 01 to 15)
* To delete the input file from flash:
* - mem spiffs remove -f hf_mfcsim_dump.bin
*
* - mem spiffs remove -f hf_mfcsim_dump_xx.bin (Notes: xx is form 01 to 15)
