AD9850 Signal Generator

Hi all.

Technically this is not a new article but an extension on the previous one I did on this 9850 chip. I wanted to get this device to work as a standalone signal generator and the results where pretty outstanding.

This is the DDS9850 module connected to my freeduino which has a LCD shield mounted for control of the frequency etc.

This fella will run from 0.5 to around 40mhz without a hiccup.

Although there seems to be a slight frequency shift this can be corrected in the code.

The code for this fella is open and available all over the internet. Keep experimenting.
