Does anyone know anything about the u8g2 library for the SSD1306 librarry onflicting with pcf8574? It seems that as soon as I write to the display the inputs connected to pcf8574 controllers stop working.
I am just using standard sample code for u8g2 from this site. But have included it in a much larger sketch. With the u8g2 firstpage / nextpage loop my pcf8574 inputs work fine. But as soon as I include those commands the inputs stop working.
