#87459 - glitchy? Responding to: ???'s previous message |
In New Zealand you arewalking upside down, aren't you? Maybe that's why the interrupt is on opposite edge? :-) Sorry, I know it is a poor joke, just I could't resist... Maybe the 0-to-1 edge is glitchy enough for the mcu to see a false 1-to-0 transition, e.g. if a mechanical switch is connected? This still,does not explain why interrupt does not occur at a 1-to-0 but maybe as a startpoint? Jan Waclawek |
