The ISM303DACTR allows for vector magnitudes to be buffered instead
of individual axis values but has none of the threshold and count
features to only only interrupting when specific magnitudes are
exceeded X times.<br>

"no replacement planned". If anybody knows of a
replacement that <br>
supports vector magnitude interrupts I'd really love a
pointer to it.

Carl,
<br>
<br>
I do not NEED the delay, I just need to read the A0 at 1
ms intervals. I don't need to stop the processor for that,
I need to code it responsibly if I want it to work the
best way I want. I was being lazy expecting my time frame
to be well within the parameters required for the desired
end result. And the solution I finally did does work, but
I have now been motivated to make it better.
<br>
<br>
Mike,
<br>
<br>
Good info thanks. I have not verified, but yes I am
thinking I may have violated the watch dog. I am not sure
why you could not change a variable if it is global and
done fast. I also dug a little deeper and the ticker I am
using is not the same that you find in Arduino. The one I
am using is suggesting the flag concept as I pointed out
in the first post and is working and the idea you also
reinforced. I guess in general it is the simplest
guarantee for accurate loop integrity. It definitely works
quite well. I have looked at the micro-python. I may try
that when I get around to the Robotics with the ESP32.
That is very interesting for sure. I like the REPL concept
alot.
<br>
<br>
I can spend a little more time for a better solution. Dang
it and I thought I was done with this part. `,~)

I have 2 esp-s2 boards laying around so if someone wants
something quickly, I'm happy to send to you. I'm in the
west coast so it will take a couple of days. <br>
<br>

Please excuse my typos, sent from phone.

John,

<br>
<br>
Because we have no idea what state the variables were in
when the service
<br>
routine was called. Were they being inspected by main
code? Or modified?
<br>
Perhaps Garbage collection is in progress? Without a bit
of blocking code
<br>
to demand a known state, we're flying blind.
<br>
<br>

<br>
Robotics are on the wish list... I just have about 3
million lines of code
<br>
before I can take on another hobby.
<br>
<br>
Python is my go-to language. Only rarely do I have to use
C++ to force the
<br>
solution.
