ESP-IDF: Code for PCA8574

[uwe_pg]

Hello,

can anyone help me. A little example for the "I2C 8-bit I/O expander module" PCA8574AD. It worked fine with the libs on Arduino, but with esp-idf I have some problems.

Bye

Thanks for the quick answer.

I forgot an important thing: I need a C sample and not CPP.
