Well, a few general comments:
1) THS1206 EVM requires the 5-6K "sandwich" board to use with DSK 6711. It
seems
that not many people are using that combination, or at least if they are,
they're not
posting on the online tech forums. My guess is that it will be difficult for
you to
obtain accurate, reliable peer help.
2) The data converter plug-in is not a common approach. Maybe you can get
started by
using basic C source code and CCS project examples that come with the THS1206.
Can
you find those? Such "basic code examples" would be simpler and easier than
using
the data converter, plus if you posted questions you would be likely to get
helpful
replies, since that's a common approach.
3) One thing you might try is getting basic A/D and D/A on the DSK 6711 working.
Then use that code as your "base", and modify. For example replace the McBSP
read in
the ISR code with EMIF read, enable EINT4 to trigger the ISR instead of McBSP,
etc.
This would allow you to keep a lot of things the same -- same general code
structure,
same sampling rate (use 8 KHz), etc. You could even use #define statements to
allow
either way.
Hopefully this is helpful info, but if not I understand. Maybe someone else on
the
forum can provide specific answers.
