SPI from raspberry PI to PIC18F

This is mostly for my own reference later:

The following is confirmed to work:

I've connected the raspberry PI as an SPI master. Only output and clock from the PI must be connected, not the PIC18F SPI out, as the PI is not 5V tolerant.

In my special PI-to-xonik m8 voice controller cable, the following pins are used:

PIN0: Signal (Master out/slave in, PI is master)
PIN2: Clock
PIN7: GND - NB - NOT PIN9!

These must be connected to the following on the EasyPIC 3 card:
RC3: Clock
RC4: Signal (SPI in)
RC9: GND

With this connection, the following settings work:

PIC18F:
SPI1_Init_Advanced(
SPI_SLAVE_SS_DIS,
SPI_DATA_SAMPLE_MIDDLE,
SPI_CLK_IDLE_LOW,
SPI_HIGH_TO_LOW
);

(incidentally the same as in my libstock example)

Raspberry PI:

let mode = 'MODE_1';     // clock idle low, clock phase active to idle.

function initSPI(){

  var spiConfig = {

    'mode': SPI.MODE[mode],   

    'chipSelect': SPI.CS['none'], 

    'maxSpeed': 200000

  };

  spi = new SPI.Spi(

    config.spi.device, 

    spiConfig, 

    function(s){

      s.open();

    }

  );

}
