Moving CC3000 IRQ pin to B2, so I2C1 can be used

In default configuration, CC3000 will use all pins available for I2C1 SCK - which is kinda lame.

Can I move it to B2 by changing

[#define](https://forum.espruino.com/search/?q=%23define) WLAN_IRQ_PIN      (Pin)(JSH_PORTB_OFFSET + 8) // active low

[#define](https://forum.espruino.com/search/?q=%23define) WLAN_IRQ_PIN      (Pin)(JSH_PORTB_OFFSET + 2) // active low

in board_spi.h?

There are still other I2C ports available though?

But yes, changing the definitions should work fine.

Yeah - there's I2C2, so this is only relevant if you need two I2C buses for something. But it's good to know I have that option.

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.
