Hi,
I fear there is a failure in the PCF8574 module. Whe i write to the expander with the adress 000 it works, but I am not able to read the data from the other chip. When I use the Arduino App, everything works just as it should. Can you please help ?
my regards

Hello,
Not sure why this isn't working I've looked through the code and it all seems ok.
If you only have a single PCF8574 component connected to address 1 then does this work. Just wondering if we can narrow down where the problem is.
