Is there any specific purpose/special functionality for each pin group(A, B, C)?

Arduino had A be analog, and D be digital, is espruino the same?

@Samarthwiz, no the A, B C refers to the GPIO ports (groups of i/o pins if you like) on the STM32F103xx chip. Microcontroller pins usually have more than one function, ie. can be both analog or digital in the Arduino sense. You can see what each pin can be used for in the reference: Espruino Board

@ltj: Thanks! That pretty much sums it up :)

The names are the names that the chip manufacturer gives to them. If you were writing C code you might have to worry about which port they were on a bit, but Espruino handles all of that so all you need to do is look at the board reference that @ltj posted up.

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.
