Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

If you use the PIN function to read an analogue value, sure. Take all the calculations and screen drawing out of the loop and it will go lots faster.

To go faster still, look at the ADC commands that can fill a DIM'ed array at 100+ times the frequency.

I ' m trying for ' real time ' so needs be ( I think )
the screen drawing .

Yes .... I tried that this afternoon . Definitely faster ,
even doing the screen drawing while filling the array .
And has the triggering !
BUT ....
Seems to lack some accuracy ?
