Wake on time

Hello everyone,

I plan to let my Espruino wake up on a specific alarm time. In the meantime the board should be ideally in deep sleep mode.

Is there a better way to realize that instead of waking the board by an interval to check the time frequently?

Maybe there could be a feature "setWatchTime" in the future.

Best,

Tobias

Why not use setTimeout()?

You mean to calculate the milliseconds to be in sleep mode until the next alarm comes up? Could be an idea.

Yes, that'd be what I'd suggest. It should be really easy to do - simplest is just (timeToWake-getTime())/1000

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.
