volume is fully working, both boards....
I can hear noises when i switch inputs etc. but not for all of them.
oh and yes i can see activity on all the dif bargraph led's
checked the cable as well it is wired correctly.
as far as I can tell I think I have set the addresses correctly.
I think I did connect the lcdduino to the d1 board before setting the options is that bad?
also I am using this pcf chiphttp://www.mouser.com/Search/ProductDet ... PCF8574APN
is that an A type or non A type?
Product says ap but then it says pcf8574 logic family at the bottom.
