Hi RichieJH, Yes i have gone through this but my main question if i want to connect pn532 with nrf51422 by spi protocol . . .which physical pins on nrf51dk i should use . .for clk, cs, miso, mosi and irq pins.

The DK specification including all the pin outs and characteristics are here -> infocenter.nordicsemi.com/index.jsp . If you are generally looking at guidance on how to connect wire an SPI device there is good information here -> learn.sparkfun.com/.../serial-peripheral-interface-spi. Give it a go and then come back with some specific questions.

Hi RichieJH, i am specifically talking about following example for nrf51dk : devzone.nordicsemi.com/.../ i have made connection according to above example with pn532 and testing nfc type2 passive tag with pn532 but as describe at below link : infocenter.nordicsemi.com/index.jsp

under Testing i have configured putty as described but i can't get debug data on pc serial console . .. is there any requirement of serial to usb chip between nrf51d and pc ?
