AVR-Chat

Erikc,

The AVR provides clock sources for a set of switched capacitor filters used in a communications project.

The AVR takes the 3 rotary encoder and 5 buttons as inputs, runs some switching control lines and provides these clock signals which determine what frequency the filter is tuned too.  And it provides an LCD output to the user so you can know what the filter configuration is.

There are some pics and a topology shot here:

Mind if I ask what you are doing with this kind of code?

In my case, I'm trying to come up with a digital readout for my mini-mill.
