hello, I was wondering if anyone knows of some chip, or circuit to generate a 500Hz to 10KHz squarve wave. I have used really old VCO(lm331) to do so, but i want to control the frequency digitally, as well as the enable/disable of the signal. this is because every time I enable the system, the wave has to start, with a little delay, but with the VCO, sometimes is in the middle of the pulse, so i have to do a feedback to the processor, and still not very good.
I used a microprocessor (16MHz) to do so, but makes it to be really busy, so I can't do any other process, so I think is a waste.
So if anyone has any idea, will be nice!
Thanks
