Hi, it seems using the mentioned function crashes the Puck reliably. I encountered this on two different Pucks. I also tried writing (using poke8) to the task register directly, same effect. So something seems to be wrong there. Is anyone else seeing this? Could this be some missing initialization? Some wrongly handled interrupt?

This could be the Bluetooth stack getting in the way - I think most likely it worked before Bluetooth got added, but then when Bluetooth is running it gets upset when certain things are accessed directly.

I've added a bug for this: https://github.com/espruino/Espruino/issues/1010

Chances are the call needs to use a softdevice API rather than using the hardware directly

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.
