DAC in the schematics

[pkallback]

Hello soulnafein!
I have a comment to your schematics to make it more simple (maybe).
Have you considered to use PWM instead of the DAC? In principle, since the PIC have 16 bit resolution PWM and you are using a 12 bit DAC, you can use up to 5 PWM's to generate analogue signals instead.
