"Internal Error: Timout on utility timer"

It seems that digitalPulse() will give errors on subsequent attempts to call it. It works normally the first time only.

digitalPulse(C7,0.1);
=undefined

digitalPulse(C7,0.1);
INTERNAL ERROR: Timeout on Utility Timer
=undefined

Happens in both v50 and the v51 github version.

I'm not sure what the default value is for time or if you want 0.1 to be the time. I believe the second param should either be 1 or 0, nothing in between. Try setting it all params explicitly, like this:

digitalPulse(C7, 1, 100)

And make sure that 100ms pass before running it again. Here is an example where I'm pulsating the led every 2 seconds, check out line 45.

The official reference lists the format as digitalPulse(pin, state, time), where:
- pin id
- state either 1 or 0 (for high or low)
- time in miliseconds

Oh, duh.

I was omitting the second argument, and meant that 0.1 to be the time, no wonder it wasn't working.

Glad you got this sorted. I'll look into why it didn't just give you an error - it should do...

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.
