Hi guys. I've made a macro keyboard 2 years ago with a pro micro and i wanted to reprogram actions but since i re uploaded the code (that was previously working fine), it seems that the pcf8574 state of all pins is always HIGH (1). Button pressed or not, always 1. Maybe something changed in the lib…
