Hi Everyone,
is it correct and intended that setTimeout prevents the screen to turn off, while setInterval isn't?
Also there is an error in the API Reference of setTimeout (http://www.espruino.com/Reference#l__global_setTimeout)

If you want to stop the function from being called, pass the number that was returned by setTimeout into the clearInterval function.

I think the function clearTimeout is meant here. Also if my statement above is correct it would be nice to have it documented :)

No, it's not intended at all, and I'm pretty convinced that isn't the case :) Are you calling g.flip()? I know that can prevent the screen from turning off...

Thanks! Both will work I believe as they are the same function, but that is still confusing. I'll change the docs

Oh okay, yeah g.flip() is prolly the reason in my case.

I remember using the LEDs will keep the screen on. Worth checking.

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:

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.
