Hello,
Forgive me if this is a duplicate or stupid question, but for some reason I cannot find it in the PDFs.
Motivation:
We have a sensor that generates anywhere from a .6 to .9V pulse given a certain stimulus (think piezoelectric accelerometer). I am hoping to hook an interrupt to this signal to essentially keep a count, however I suspect that .6-.9V is below the threshold for digital logic.
Obviously I could amplify this signal, but I am hoping to keep component count down, so my questions are:
- What are the logic level thresholds for the psoc 6 GPIO interrupts?
- Can those levels be tuned or are they relative to some reference voltage?
Thanks for any help!

Hi,
Although I am not good at analog stuff, I think that you can use Comparator along with VDAC to do what you are asking.
Please read datasheet of each components for the details.
