"no replacement planned". If anybody knows of a replacement that
supports vector magnitude interrupts I'd really love a pointer to it.
Thanks,
Pete

Carl,
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.
Mike,
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.
I can spend a little more time for a better solution. Dang it and I
thought I was done with this part. `,~)
Thanks,
John Vaughters

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.
Please excuse my typos, sent from phone.

Nick,
Please put me down for 5 of these. Do you Zelle, PayPal or GPay?

John,
> I am not sure why you could not change a variable if it is global and

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

That is
very interesting for sure. I like the REPL concept alot.
Robotics are on the wish list... I just have about 3 million lines
of code
before I can take on another hobby.
Python is my go-to language. Only rarely do I have to use C++ to
force the
solution.
