Espruino 'Quick Reference Card'

Hi,

I'm going to include a small (business-card sized) piece of paper with each of the Espruino Picos. It's got a QR code, link to the Quick Start, and the Pinout on it.

However there's a small bit of space down the side, and I thought it'd be worth having a 'cheat sheet'/'Quick Reference' on it... So what do you think should be in there?

It is quite small (1/3 of a business card) - so it needs to be simple.

Thoughts so far are:

// Light LED1
digitalWrite(LED1, 1);
// Blink LED2 for 150ms
digitalPulse(LED2, 1 /*polarity */, 150);
// Turn LED1 off after 1 sec
setTimeout(function() {
  digitalWrite(LED1, 0);
}, 1000 /* millisecs */);
// 40% duty cycle, 300Hz square wave
analogWrite(A8, 0.4, {freq:300});
// Internal pullup, read value
pinMode(B15, "input_pullup");
console.log(digitalRead(B15));
// Read analog value every 100ms, light LED1
setInterval(function() {
  var a = analogRead(A5);
  digitalWrite(LED1, a>0.5);
}, 100);
// When button is pressed
setWatch(function(e) {
  console.log("Press at "+e.time);
}, BTN, { repeat: true, edge: "rising", debounce: 50 });

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

> Quote text by starting lines with >

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.
