SPISlave block after some reply

[DrDiettrich]

Updated example:

@falsinsoft

#define device SPI
void setup() {
  ...  //insert SPI initialization here
  device.reply(getNextByteToSend());              // Prime SPI with first reply
}
void loop() [
  if (device.receive()) {
     int v = device.read();   // Read byte from master
     ... /handle received data
     device.reply(getNextByteToSend());         // Make this the next reply
  }
}

Add byte getNextByteToSend() as appropriate.
