Hi Tim
So, running GPIO readall, this is the output. Consider that Moode 4.1 is running, and that the HifiBerry DAC PRO+ il pluggeg onto the RPi.
I suppose that the GPIO with ALT0 mode are the ones used by DAC. I don't understand the V columns. Are there any GPIOs not properly working? How can I test them using the gpio command parameters (I didn' found any kind of help on web...)
Thanks
