This may be where my programming knowledge falls short but I'm not sure you can set a frequency per I/O pin. (That's where i was going originally before the thin trail of smoke erupted.)
The PWM outputs I *think* are frequency-adjustable, but hadn't gotten there yet. (And I may still pursue that route)
One problem I ran into with the original circuit was that the Freq-to-Aircore driver chips had a non-linear response curve. (More like a logarithmic response curve and I would probably need to build reference tables to remove that log behavior)
Gotta crack a few eggs to make an omelet I guess.
Now, for the serial plan... What I hope for is to have a single data line shared by all CS4122 chips , with multiple CLK lines. (One per chip)
I love research! :-0

Got me some of these:
CS4122
Mouser still has them. I've never soldered a SOIC device before... looks like a trip to Fryes is warranted!

Well keep in mind that if memory serves, you don't need multiple threads
to drive those things. You set a value on the port and it'll stay there
until you tell it otherwise. I could be wrong of course - I haven't had
time to play with them yet.
What chip did you find for driving the air-cores serially?

It's a good reason to keep some of the ATMega328 PDIP based versions of
the Arduino handy. If you cook it, you just stick the bootloader on a new
one and go. You'll need to build an ICP cable or have an STK500 (or
similar) programmer to burn the bootloader on it though.

Not having looked at the specs, I would recommend using the chip enable
pin if one is present. That lets you keep common data & clock lines
across multiple parts. If CE isn't set for the part in question, it'll
ignore the clock & data lines.

Chip has a Si, So, CLK and CS so hopefully that will suffice.
Just noticed that the full 360-degree gauge output has some interesting serial data input requirements.
Major Gauge (360°)
MSB LSB
D11 D10 D9 D8 D7 D6 D5 D4 D3 D2 D1 D0
|Gauge |Quadrant| Data |
|Select|Select | |
...that should be fun......

I suspect "CS" == Chip Select. :)

No! NO H-Bridges! :-)
I also have on hand some MLX10407 chips that don't use that (soon to be)
ugly "Quadrant" datatype. I might give those a whirl as well...
(Still the SOIC form-factor so Fryes still requires a visit)
New Arduino board inbound! :-D

Hmm... just figured out I can use Arduino to control some BCD to 7Seg
decoder/Drivers..... (like the 7447 / 7448)
Is it sad that I didn't even have to look those chip numbers up? Even
that the 7447 drives common cathode displays while the 7448 drives
common anode....
I used to spend my allowance at Radio shack as a kid.... I've long
forgotten the pinouts, but I could probably still recall the 7400 NAND
gate pinouts if I really tried :-)

The (new) Arduino is up and running, spitting data out to both an LCD panel and also sending a 12-bit data stream using CS, CLK and DATA outputs. I have it cranked up pretty fast.. should be sending about 30 updates a second.. should be more than enough for smoothness.
Tonight I solder the CS4122 SOIC chip to a makeshift breadboard breakout card and start wiring things up.
I know what happened to my original Arduino... My breadboard power rails had (had) a ground, +5vdc and +12vdc rails. I was wiring up a switch, and the circuit called for a 1m pull-up resistor. I mistakenly plugged in a 100-ohm into the 12vdc rail.
Now I have the rails a bit more segregated and 12vdc is isolated to a single rail so it's out of the way and not as tempting.

No, that would be the wrong omelet.
The SPI way is one data line to all chips, (or chain of chips,) one clock
line to all chips, and one CS *per* chip.
Only the chip that has an active CS will accept the data, all others will
ignore it.
(And again, if you have different chips, CS may be active high for some
and active low for others.)
See the wikipedia page I pointed to before and a few links from it.

That 16x2 LCD panel is invaluable for seeing all your programs' VARs in

No, you just need some crazy good eyesight and a 12 year old with no hand
tremor to solder up the parts. :)

I've got the Arduino ramped up as fast as it will go... I found that a
384uS delay in the Serial data between CLK IN and DATA IN provides just
enough software dampening to make it realistic. 384uS is enough room as
well to logically add more gauges to the same card.
