Is DAC voltage 0-3.3V?
I need a 1.1-3.90V to simulate a joystick.

Try it:
analogWrite (pinX, 0x0fff);
put a meter on & measure it.
It's between 1/6 and 5/6 of 3.3v. So it does not start at 0v and does not end at 3.3v
That is odd. Still, will not reach 3.9V. Easy way might be just add a 0-5V opamp and SPI the data that corresponds to the range you want.
Or two I guess, for left-right & in-out.

Could also mess around with op amps, add some offset and adjust the gain so it goes 2.5V +/- 1.4V
