Re: DAC software

I would like to incorporate a DAC in a board design so as to provide
some biases in the rest of the circuit and was wondering if anyone
knows if any company provides software that could program their DAC
through the serial or parallel port. Unfortunately, there is not much
time for designing and testing so I don't have time to write the
program myself. There are no tight specifications on the DAC
(preferably running at 3.3V and accuracies of 10bits and up are fine)
so basically any DAC will do as long as it has ready software to
program it.

"Program" a DAC??? Why not just get one with a parallel interface and
write to the silly thing? For example, one I remember from cave-man days
is the MC1488, which just has 8 input pins, and when you write your
data to it (via a latch, probably), it just puts out the corresponding
current, which can be converted to a voltage with a resistor.

Good Luck!
