Hi,
I've implemented the design of my friend VA3FGR with a DDS module with AD9851 and PIC16F876A to build a signal generator from 0-70Mhz.
The design schematic and the hex file you'll find on my page : http://www.danolteanu.webs.com

Thank you,
BR/Daniel

Hi,
When I've built it first time I've used AD9850 and it works fine until 40Mhz.
As I had also AD9851 I used it up to 70Mhz, but with some software changes.
The soft with AD9850 is attached.
