Timers have me beat

[Doormatt]

Here's the math I used to come up with my output frequency.

The internal clock executes at 1Mhz.

If I use a 1:16 Prescaler, then it will take 256*16 clock pulses to overflow Timer0. 1,000,000/(256*16)=244Hz

Math was never my strong suit though...

I moved the enable/disable to where you suggested, and now I'm getting a 10Khz signal.

Getting closer...

EDIT: WOO! I forgot I'd changed another value! It works now! I'm getting my 244Hz signal! Thanks so much!
