Hi @lshk it appears you may be the first with this specific device functionality.

There seems to be an apparent mis-understanding of how Javascript timer events work in comparrison with Arduino delays.

While Arduino code continually loops and toggles a pin with a delay, the timeout L57-L61 that triggers the L58 shot() function, will run after the timeout interval has elapsed.

This will take a bit of finagling, but first check out with it's live online 'Try It' windows

Ok, but that's not the problem here. I removed all delays, commented out digitalPulse, but these loops are very slow. At this cycle rate, the pulse transmission frequency does not correspond to the required.

'the pulse transmission frequency does not correspond to the required'

What is the frequency? How is this being determined? O-Scope? Logic Analyzer?

I have an example Logic Analyzer image, it is with SPI, but just showing to demo the capturing of example data and frequency.

Proper technique needed to nest a setWatch()

Are you able to post something similar?
