5. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.

Running the demo

When the demo runs successfully, the log would be seen on the terminal like:

Card size xxxxx bytes

Working condition:

  Voltage : xxxV

  Timing mode: xxx

  Freq : xxx HZ

Read/Write/Erase the card continuously until encounter error......
