After seeing how the first version performed, I'm now working on the next version which will fix the issues I had in the first one and add a few extra features.

The features are:

- External amplitude input
- External DC offset input
- External frequency and phase selector
- Sweep trigger output

The firmware is very crude at the moment, so I'll be posting the source once I have it a little bit more usable.
I'll also post the board project files once I complete the version 2.
