Rewire auto adjust ladder to R-2R configuration #7

Closed pyr0ball closed 5 years ago

pyr0ball commented 5 years ago

On advice from a user on reprap forums (dc42) I will be increasing the adjustment ladder resolution by switching from it's current configuration (series ladder) to an R-2R parallel ladder configuration.

This will increase the number of possible values from 5 to 16 using the same number of pins. It should also allow for simplified code

Closing this issue as I've elected to use the arduino PWM output as VRef adjustment: https://github.com/pyr0ball/pyr0piezo/issues/15
