Absolutely. The values I've hard-coded have come from the definitions in the (TI) data sheet. This has been confirmed by probing the pins on the board and measuring the clock frequencies. > Other rates might be supported by resampling the signal rather than the > hardware actually running the A/D or D/A at those other rates.

When I initially discovered the driver did not support my desired sampling rate, I tried higher sampling followed by resampling, but it introduced too many artifacts (I'm FFT'ing the signal). There may be smarter resampling techniques, but it's all clean (and efficient) with the hardware at the correct rate. I may have a look into providing a patch, to at least avoid having to patch myself on each new release.
