I know it has come up before on finding a timing diagram font, and most
people will point you to Xwave, which is fine if that is sufficient.

I have created a new timing diagram font, for free use (no selling it).

See <http://www.pcserviceselectronics.co.uk/fonts/>

I would be interested in feedback as I find it better for *my* use.

Very nice! I just started work on an interface speck for a
modem today and needed to draw some timing diagrams for SPI and
I2C transfers. I copied the .ttf file into

Having decent group markers for a complex SPI design I had and
good transitions for I2C to pulled up on seperate in and out SDA
for I2C was one of my reasons for doing it.

/usr/lib/openoffice/share/fonts/truetype

That I assume was Linux flavo(u)r of *nix...

Yep. Gentoo to be specific. I'm sure there are both user-local
and system-local places I should have put the file as well (if
I leave it where it is, it'll probably "go away" the next time
OOo gets updated).

and it "just worked".

It even displays and prints properly when the document is
exported from OOo as a PDF file.

The only think I could think of that might be added are
transitions between "group" and low/high.

At this stage it was intended to use

{} (curly brackets/brace) for transition from group to tri-state
[] (square brackets for transition from group to High/Low/Pulled=up

That's what I used, and it's quite adequate. It's just that
the sloped transition for the {} case and the square transition
for the [] case are visually different enough that it might
lead a reader to infer that the difference between square and
slanted is meaningful.

I will have to think how to easily get 4 more transition key
mappings for high/low to or from group with group ending in
'chevrons'.

It hadn't occurred to me that you were out of key symbols. Are
ctrl characters allowed to have printable glyphs?
