title: Seeedstudio NFC Shield v2.0 I2C
body: <p>I am using NFC shield v2.0 and it seems Sel0 and Sel1 pins are set for SPI mode and we cant change it (saw in schematic files). So is there any way to change the values on this pins via software(program) to make it to work for I2C mode?</p>
  
  <p>and inDataExchange function is not a member of SPI.cpp library while it is in I2C.cpp library?
  is there any way to make HCE work with SPI mode?</p>
