From your description it sounds like the pindirs or the GPIO pin function aren't being set to PIO mode correctly for some of the pins. Looking at the code in https://github.com/raspberrypi/pico-exa ... 12.pio#L70 , it appears that it should setup the OUT pins and pindirs correctly though. Maybe someone else can look at the linked code and see an obvious bug.
