Hello,
I want to use a PIC as a two output DAC. I was looking at the PIC16F685 to do this. It has 4 PWM channels, and is the cheapest that I could find with 2 or more PWM channels. Does anybody have any cheers or jeers for this PIC?
After I choose my PIC, anything special I should look out for making it PWM? I think I can figure most of it out from the datasheet. I prefer to program in C.
What circuit do I need to use to make the PWM be a DC voltage? Will a simple capacitor work? What kind of response times will I get using said circuit? It is important that this be able to change the DC voltage very quickly.
Thanks!
