Congrats!  Welcome to the Hack-a-Day published club!  You deserve it!

Heh, no, I didn't see that page. Oh well, glad I could help.

I'll probably end up implementing it in the thermostat I was working on, instead of the LCD I was going to use, as this already had buttons and status LED's built in.

Thanks again!

YES!  I have had this VFD board sitting in my drawer for about a year now, itching to use it in a project.

Thank you very much for documenting this, extremely helpful!  Thank you even more for the PM to inform me of your post!

*Tips hat*

:: Update ::
Got a chance to hook mine up and try it, and it works!  Mine only had 9 pins in a single row though, so I had to determine the correct connections for mine with a bit of trial and error (along with some help from a multi-meter)

Here is the pin-out for my board:

Pin 1 - Ground
Pin 2 - Ground
Pin 3 - LED/Button dataReadPin
Pin 4 - LED/Button latchPin
Pin 5 - VFD chipSelectPin
Pin 6 - clockPin (for both)
Pin 7 - dataWritePin (for both)
Pin 8 - +5 Volts
Pin 9 - +5 Volts

Thank you very much for the reply! This had been driving me nuts trying to figure out how to use Timer1.

I had also PM'd Brett, but I guess he got back to you first smiley-grin

Can I assume that only Timer1 is 16bit? For my project, I actually need 2 outputs (to drive a speedometer and a tachometer, both requiring a square wave with a frequency range of 0 to ~230 hz).

Thanks again!

I second this question. I have been looking to do the exact same thing.

I second this. I have a couple of these displays laying around that I would love to include in some projects, but don't quite have the knowledge to implement my own library yet.

Any updates on this problem? I am currently trying to drive a Speedometer out of a Jeep with my Arduino using the Tone() function.  I am running into the same problem, where the wrong frequency is put out if you go below 31Hz (16 MPH on this gauge).  I only need a range of about 10Hz to 220Hz to drive this gauge.  It sounds like that 16 bit timer Tone function would solve my problem, but I don't see any way of making use of it. Any suggestions?

Any help would be greatly appreciated.
