Thanks all i found answer on this post.. https://github.com/espruino/EspruinoDocs/issues/258

Solutions:

var spiSoftware, chipSelect, rfid, rfidTest;
function onInit() {
  spiSoftware = new SPI();
  spiSoftware.setup({
    sck: D14,
    miso: D12,
    mosi: D13
  });
  chipSelect = D15;
  rfid = require('MFRC522').connect(spiSoftware, chipSelect);
  setInterval(rfidText, 2000);
}

function rfidTest(){
    console.log("trying to find card");
    return rfid.findCards(function(card){
      return console.log("Found " + card);
    });
  };

Formatting Help

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:
![](https://www.google.co.uk/images/srpr/logo4w.png)
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

> Quote text by starting lines with >

Mention another user by @username

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

```
Your code goes here
```
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.
