Calculating minimum and maximum values from a single input
Hello all,
I am trying to solve a dilemma that seems to require some sort of math based operation.
Here is what I am doing:
I have a heart-rate sensor from an Arduino printing to serial a beat. This beat I have incoming into Max no problem. One element of my patch will be to use this number to make a visualization beat to the users heart-rate. I hope to create a more standardized visual that updates with changes in user or changes in heart-rate.
My question:
How do I take ONE number, that refreshes like 100+ times per second, and get a 'recent' average of this number for say over 5 seconds. More precisely, I hope to get a minimum and maximum values. These values I will then port into a scaler to effect elements of a jitter visualization.
use zl stream to make a continuously-updated list, then just use the min, max, and mean objects
Thank you!
I read up on the elements you posted and I really don't understand why inserting "stream" is needed. I understand by inserting it it acts as a limitation, but somehow oddly enough the act of adding it also seems to change the class of the zl object itself? For now I will just use it blindly I suppose, haha!
that's right, zl has many modes of operation-- you have to explicitly state what mode you want, so the word "stream" is an argument of the zl object. Here's a simpler example of how it works:
zl is somehow special here, it wont operate unless it is given an argument for its modes.
that is why since max 6 you are also allowed to type [zl.stream] and call the different modes by a single object name.
for max4 and pd you still have to use messageboxes or coll to do the same ;)
