SNAP! Lives!

29 Mar

Today I got around to marrying the SNAP! firmware & software systems to my breadboard hardware system – it lives!

There still some work to be done on the hardware getting the zero-signal baseline voltage down where it belongs and on the SNAP! software system to get the log display scaled properly, but we do have functionality.

Here’s a screen capture of a 6-pole crystal filter I made about 25 years ago. Display-line markers are turned off for now. You probably can’t tell by looking at it, but the log range is a bit exaggerated and the filter is actually much flatter than it appears. I’ll be working on this.
