  • Thanks! Actually you might find software SPI easier. Just do:

    var spi = new SPI();
    spi.setup({ sck:D14, miso:D12, mosi:D13 }); // or whatever pins

    And then you can use any pins.

    To do a quick check, you could also try shorting MISO to MOSI (without the module attached) and running spi.send("Hello") - Hello should get returned.
