I was wondering if anyone could explain to me the difference between the gpio.trig types up and high or down and low.

up and down are edge triggers -- that is a transition from low to high or v.v. high and low are level triggers.

So, if we are using the gpio.trig which takes a callback function that takes one argument, level, then what should be the value of level based on the type? I'm guessing high would be 1 and low be 0. What about up/down? What would be the value of level?
Thank you TerryE for the reply.

Up and down are edge triggers. So on up you have a low to high transition and if read as high by the interrupt routine.
