im not sure what type of IC's im going to use yet,
ive designed all main PCB that does all the switching and volume control for a 4x4 matrix, as everything will interface on i2c i can design bits at a time,
this is mainly for the wall plates to be put in each room and if i could replicate each wall plate on the main system front panel, i might just use a screen and send the info to it if i have to code further.
thanks for the help!
