I wondering if is possible to use a DAC of Arduino2 as "arbitrary" waveform generator.
I imagine is possible to simply "write" a numeric value (a vector of values from a file for example), isn't it? Which is the maximum rate?
Instead, using the standard Arduino Library, what is the maximum frequency?
Thank you very much

What is "Arduino2"?
I think best performance may be achieved with SPI data sent to an external DAC.
Default data rate is 4 MHz; actual data rate will depend on how much processing your code does between messages that are sent out, and your method of controlling the chip select line.
He probably means Due - isn't that Italian for 2?
Sorry for the late.... and thank you to CrossRoads for the suggestions.
Yes, Due in Italian means 2.
Also if I can obtain the best performance in terms of rate with an external Dac I would like to use one of the two internal DACs of ArduinoDue even with a low rate.
