    Hi, I bought PCF8574AP, connected it to NodeMcu with OLED display. Display works great but a module set High on all outputs and does not change after setting on in Openspringler. Could You help me?

    Hi, could someone help me with connecting PCF8574 to NodeMcu?
    I compiled nad successfully uploaded a sketch to NodeMcu and all is fine except communication with PCFmodule – I set A0=1,A1=A2=0 and I can not change a state of SSR High level trigger… Should I change sth in source code?
