GPIO interrupt
Posted: Mon Apr 11, 2016 10:47 amI'm trying to use interrupt and have two questions:
1. How short can the pulse be to be recognized? I am working with 25ms pulse and that seems to work fine but I'm not sure how close to minimum it is.
2. Is there a way to identify if falling or raising edge triggered the interrupt?
