Maybe.

If you are trying to get data from a Pi to an Arduino at a reasonably fast
rate. Use USB. The Arduino has built-in USB as does the PI. USB is
great because it is a balanced, differential signal. It is way-faster then
you need for this purpose.It is also very easy to use from the software

Interesting! Is there support for isochronous transfers at both ends? Do
both ends support host/target roles? Can you configure both ends for
arbitrary VID/PID?

I don't know if the Arduino IDE has isochronous USB library but you can
always implement it yourself. Of course it is already supported in the
Linux side.

Good day gents. Trying to get a handle on sinusoidal commutatation. I need
2 pins 0-5 volt 120 degrees out of phase to commutate my drive .

I find this in the docs , and am curious if the 7i90 can be coaxed to do
this and I do
