Hi Gordon,
I received the board few days ago, so exciting adventure.
Unfortunatly, not had time to play with it yet..... frustrating :)

I have a question regarding interface.
I have a few ideas that might require the use of NFC (as I also pledged for the NFC ring on Kickstarter :) )

I found this card that can use I2C : http://www.seeedstudio.com/depot/Xadow-NFC-p-1627.html?cPath=19_24

Do you think that it could be feasible to use NFC with Espruino ?

Thanks for your hard work :)

Yes, NFC should work great - although I haven't done anything with it so far. I've been meaning to for a while though so I have just ordered a kit.

Personally I wouldn't use Xadow - it had weird connectors. I'd just use one of the many other things that use the same chip and are cheaper: http://www.ebay.com/sch/i.html?_nkw=PN532+nfc

Splendid Gordon :)

Might I ask you which kit you ordered ?
Since Espruino works like Node.js fashion way with 'require' for module,
is there something we need to communicate with NFC ? any library that could "automate' communiation and NFC management?

I ordered this one: http://www.ebay.co.uk/itm/NFC-RFID-module-kit-PN532-Card-Key-Arduino-Compat-/131103603834

I'm afraid it's going to need a JS module writing for it. It doesn't look too painful so hopefully I'll be able to knock something up quite quickly - at least enough to handle a basic type of NFC.

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.
