Espruino Pico and SD cards

small example with SD card module connected to SPI1

function onInit() {  
  // initial SPI1 for SDCard module
  SPI1.setup({sck:A5, miso:A6, mosi:A7 });
  E.connectSDCard(SPI1,B1/*CS*/);
  console.log(require("fs").readdirSync());
  require("fs").writeFileSync("hello.txt", "Hello World");
  console.log(require("fs").readFileSync("hello.txt")); // prints "Hello World"
  require("fs").appendFileSync("hello.txt", "!!!");
  console.log(require("fs").readFileSync("hello.txt")); // prints "Hello World!!!"
}

// call onInit() if it is first start
onInit();
