This is my first post on this great forum! I have been reading up on Arduino and C for a week or so now and I am starting to think I can maybe do some interesting things with this platform. BUT I have so many questions.
For now the biggest involves sound.
Let's say there is a program that I want to use, but it is set up to output its sound through the PWM pins. However, I would like to use the proper pins for a resistor ladder (R2R) DAC.
I am under the impression that I am supposed to use the DIGITAL pins. But it seems like most audio related things in Arduino are setup to use the PWM pins. Is it possible to start a sketch using the PWM Pins for testing and then move its output to the digital pins for R2R?
Eventually I would like to read an input, perform operations on it, and then get it to come out of the DIGITAL OUTS.
it all seems so confusing. but the DIGITAL OUTS seem like the best way to get around 256 steps.
( a big specific goal would be to have a wave table oscillator take advantage of the DIGITAL PINS)
thanks so much for any answers or links or books , etc. I will read all of it!!
