Hmm, I'm not sure about that. I know that SDI (Master) goes connected to SDO (Slave) and SDO (Master) goes to SDI (Slave). But, a quick search in Google for SPI wiring will bring you some circuits like this,

As you can see MOSI goes to MOSI and MISO goes to MISO. . I am trying to connect my PIC to an NFC module that only accepts SPI. The ports of the module are labeled as MOSI, MISO, SCK, and SSEL. I haven't had any luck getting a response from the module yet. Can I use SHIFTIN and SHIFTOUT in this case?
