Hi, I am using the psoc 5. I am trying to make an interrupt as soon as the voltage on one of my digital input pin gets to 0 or close to it (set to be Resisitive pull up). The problem is that I want the interrupt as soon as the voltage gets to 0.4V or lower and the interrupt is only initiated if the voltage on the pin is hard 0.

How can I solve this problem.

Thanks a lot for all the help

When you are interested in a particular voltage you may use a comparator component. Set the switching/interrupt point externally (resistors) or internally using a DAC. You need to configure your input pin as analog I/O
