KC868 A8 - Help In Program

[mfjunior96]

Goodnight,

I'm having trouble using the codes to use the PCF8574 of the KC868 A8, using the same code for input and output, I noticed that it already comes with the standard Digital Input 1 > Turn on > Digital Output 1, does anyone have this code so I can work above him?

Thank you very much in advance
