if i want to build a 12or more bit dac with 8 channels that uses USB as an interface, what do i need?
other options that would be cool are
ethernet interface
SD card.
Most rabbits (if not all) do not have usb support, so have a look at the FTDI chip’s. There are sample’s in the sample directories for these chip’s. And the Ftdi chip’s are pretty easy to use. They even come with drivers for windows/linux.
Further more, there are plenty sample’s of serial (incl rs232) DAC projects. So you have to put 1 and 2 together…
