which pga's support hardware mode? I thought they needed cpu data to get them to work.
there's an older ds1802 that used up/down click buttons (rotary encoder that is pulsed) and also supports software mode.
pga2311 (which is the base config that I've used) has only an SPI style interface. or am I missing something?
