  KC868-A8 and PCF8574 Interrupt pin
Posted by: andhol - 05-31-2022, 07:53 PM - Forum: KC868-A8 - Replies (14)

Hi!
I am planning to use all 8 digital inputs of the KC868-A8, and it would be nice to be able to use the interrupt pin of the PCF8574 to detect changes. I'm just not sure if the pin is connected or not. When looking at the schematic, it looks like it is connected to GPIO16, but there is also a red X symbol next to it that might suggest otherwise.. Any hints?
