Which micro controller suits this project?
Posted: Sun Mar 02, 2008 12:29 pm
I'd like to design a project where I would have a micro controller that would take as input a few switches/potentiometers, say 3 or 4 of each max. The output would be to an optional LCD screen (3 line etc), and it would control the analog switching of a bunch of coils that I have. This will be my first shot at using micro controllers (I'm already a software engineer though).
Basically, I'd like to digitally control if the coils are in phase, out of phase, in series, in parallel etc.. I would say there'd be up to 12 maximum connections that would need to be manipulated in this fashion, with the micro controller providing the switching.
The thing here is that it's an audio application as well, and audio signal travels along the coils, so this has to absolutely not taint the signal whatsoever.
Can the majority of this work be done in a micro controller, with only a few controls? Or would I also need a bunch of transistors etc. If at all possible I'd like to do it all in the micro controller if possible.
Thank you all very much!
