How to make DAC start with last value?
The goal is to have the DAC start at the last power level where it was set before being powered down.
Looking at the API, I thought I would be able to save the config of the DAC (including its current level) with VDAC8_SaveConfig()
With my testing, it doesn't seem to do the trick. Do I need to write straight to some register? Do I need to implement some EEPROM to save my value?
