Re: FV-1 Pot Inputs - Using Digital Pot or DAC?

Thank you both for your replies. The controller I'm using is a little outdated by today's standards (MCF5206E) and has no PWM I/O. Don't ask me why I'm using that CPU, I have other reasons, but at least it is 3.3V :P Anyway, project is moving along fine and deciding if the next version will incorpor...

So, are you using PWM to charge an external capacitor / resistor network or something like that then feeding that to the pot inputs to the FV-1?

FV-1 Pot Inputs - Using Digital Pot or DAC?

Hello all - The FV-1's Sx inputs are logic inputs and not an issue to connect to a micro-controller. The Pot inputs are voltage level sensing and are little harder to connect to a micro-controller. I see two options in connecting them to a micro. 1, use a DAC for each Pot input and the output voltag...
