SSD1306 with SPI1 on Espruino Wifi

@Gordon, I'll return to the ESP8266 thread soon-ish, and respond to your last question. Thanks for the help. For now I'm making use of the Espruino Wifi so I can ignore the ESP issue.

I got some of these: https://www.adafruit.com/product/661 SSD1306 displays. I can't get them working using SPI on my Espruino Wifi. I've tried a variety of connection arrangements. It should be simple but it seems every page has different instructions. I was using the table labeled "SPI" at the top of this page, but I now conclude it must be wrong: https://www.espruino.com/SSD1306

Table says: D0/SCK/SCLK => B5

I assume B5 means SPI1 MOSI (like Pico or Espruino Board). Why would I connect clock to master out / slave in?

So I'm reading the pins from this table according to the Pico pinout, checking if it makes sense, and connecting to the A pins for the same function on the Espruino Wifi. If they don't make sense, I'm trying to connect like pins to like pins. From what I see online, MOSI goes to MOSI, SCK goes to SCK, etc.

GND => `GND`
3.3V => `3.3V`
CLK => `A5` (`A5` = `SPI1 SCK`, a.k.a. `clock`)
DATA => `A7` (D1/MOSI/SDIN = `DATA`? `DATA` = MOSI? `A7` = `SPI1 MOSI`)
DC => `A1` (Internet says any GPIO, and `A8` is inaccessible. Assuming DC = `D/C`)
RST => `A0` (Internet says any GPIO, and `B7` is not an A pin)
CS => `GND`

Because all the example snippets I find use software SPI, so do I. Here's my test code that doesn't work:

function start(){
  g.on();
  // write some text
  g.drawString("Hello World!",2,2);
  // write to the screen
  g.flip(); 
}

// SPI
var s = new SPI();
s.setup({mosi:A7, sck:A5});

var g = require("SSD1306").connectSPI(s, A1/*DC*/, A0/*RST*/, start, { height : 32 });
