Hi,
Looking at the schematics I’m not 100% sure if the PCF8574 INT line is connected to the ESP32 or not.
I would be very grateful if somebody could confirm if this is the case.
I can see there’s a pull-up resistor, which I’m surprise because I though the PCF has an internal resistor anyway.
If it is connected to the ESP32 I would greatly apreciate any information on this subject.
Thanks in advance!
Eric
