A free, GUI-based, digital and analog (mixed-signal) timing diagram drawing software for Windows 10 (and Linux via Wine).
Intended primarily for documentation purposes, electronic hardware designers can use Waveme to draw a timing diagram,
and then export it to an image file (BMP, PNG, SVG or TIFF) or a PDF document.

Waveme can be used to draw waveforms, gaps, arrows, labels, value-lines and time axis (see attached images).
Both, digital and analog signals can be drawn.
Highly customizable, with a wealth of keyboard shortcuts.

Waveme is distributed as a portable 64-bit single-file executable - it doesn't require installation.

Please note that because it is an unsigned executable file, a browser will issue you a warning, and it might be flagged by antivirus programs.

Hope you find it useful!

I've been using an

Avocent 2SVDVI10-001

DVI/USB KVM for a few months now.

It's working great for both 1600x1200 display and USB peripherals, but it's relatively expensive.
If you buy it, read the first review on newegg.com for how to use it correctly.

Thank you for making SC. It's vast but the good UI and help make it easy to find your way around.

There are 2 feature enhancements I'm interested in:
1. The option of saving images in an uncompressed format, BMP and PPM.
2. Auto-capture faster than once per second. Though, I'm not sure how fast is feasible...  :-\
