looking for i2c 0-10v controller

[garbled]

I'm looking to build a small arduino or pi zero based moonlight dimmer. The idea is to load a moonlight chart in, plug the 0-10v into the ballast, and then just turn it on at the right time.

Are there any good 0-10v (not PWM!) controllers that could be hooked up via i2c to a Pi or ESP?

If you are arduino, you can generate analog 3.3V and use an opamp to convert it to 0-10V. If you are on Raspberry Pi, you can generate 3.3V PWM and use an R circuit to get approximated analog (triangular) signal. For true analog signal with pi you can use an i2c based DAC (e.g. ads1115) to generate 5v analog, and then use an opamp to convert it to 10V
