Hello,
I'm building Espruino on custom board (based on STM32F4) which have five buttons and I would like to add the definition of the fifth button to binary. I added definitions of buttons to STM32F4DISCOVERY.py file and also I added BTN5 to simpleDevices array in build_platform_config.py but when I flash the board and try to call BTN5 I get Uncaught ReferenceError: "BTN5" is not defined. Do I need to define this button somewhere else or it's not possible to define more buttons or other devices? I found note about this mentioning that I can you LED1-LED8, BTN1-BTN4, etc., but I need one more button for convenience. Thanks for any advice

As far as I remember there are only 4 buttons built-in - but it'd be easy enough to add more.

Just do a text search over all the files for BTN4, and where it says that, copy the relevant lines and rename to BTN5 :)

Heureka, I did not know that it can be somewhere in jspin.c. Thank you very much :)

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.
