Hi
First of all - sorry for bad English

I try to connect SDCard to NodeMCU with Espruino 1.96 firmware with this manual

function onInit() {
  // initialise SPI1 for SDCard module
  SPI1.setup({mosi:NodeMCU.D6, miso:NodeMCU.D7, sck:NodeMCU.D5});
  E.connectSDCard(SPI1, NodeMCU.D0 /*CS*/);
  console.log(require("fs").readdirSync());
  // ...
}

bu as result - i see this in console:

Uncaught Error: Function "connectSDCard" not found!
at line 2 col 5
  E.connectSDCard(SPI1, NodeMCU.D0 /*CS*/);
    ^
in function called from system

what i do wrong?
thanks

For this you need custom build with SD and file system support. It's not there as standard for ESP8266. Some info which may help in this recent thread

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:

That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

```

Just like Github, a blank line must precede a code block.

If you upload more than 5 files we will display all attachments as thumbnails.
