* Example sketch/program to test your firmware.
|
|
* --------------------------------------------------------------------------------------------------------------------
|
|
* This is a MFRC522 library example; for further details and other examples see: https://github.com/miguelbalboa/rfid
|
|
*
|
|
* This example test the firmware of your MFRC522 reader module, only known version can be checked. If the test passed
|
|
* it do not mean that your module is faultless! Some modules have bad or broken antennas or the PICC is broken.
|
|
* NOTE: for more informations read the README.rst
