>> Re digitally controlled pots ...
Kirk
Signetics make a whole range of digitally controlled things :-) such as
volume controls, tone controls ... that are controlled via their IIC bus
(I forget what this stands for). This is a slow (100KHz) serial bus with
one clock line and one (? two) data lines so the chips are small (lots of
8 pin DIPs), cheap and easy on board space . They have things like dot
matrix displays with built-in decoders and keyboard encoders, 2K EEprom
(in 8 bit dip) and so on. The range filled an A4 page's worth last time I
looked.
I haven't used these (yet) - I'm waiting till I've got forth running on
an 8031 so I can do it interactively - but those I know that have
rave about the chips and the range. Signetics use them for the insides
of their TV sets ...
I have no connection with Phillips/Signetics other than an interested
observer and pending customer :-)
Cheers
Giovanni
