for my switch panel i will use the Arduino micro (not promicro). so that i can use all 96buttons and all potentially possible axis so i think i have to use two "mcp3208" so i have enough pins to make a matrix with 96 buttons without using shift register 74HC165 or 4021B to realise 96 buttons.
i need the axis only for mixture, water radiator, oil radiator, light dimming and so on therefore i think for this purpose it is not so important that the mcp3208 to get a stable 5v via an external 12v supply for getting the highest sampling rate. please correct if i am wrong
btw: stunning piece of software sry for my bad englsih
