is full). Clock and sampling frequency have been moved to a separate function from burst. There is now one function to initiate sampling called sample which takes a channel and count. setclock takes a channel, clock_id, and frequency. Adjustments should be made to make channel groupings somewhat cleaner, but this is functional. Suggestions are welcome for simplification :-) I'll try and make some doc updates in the coming day or so to reflect finalized adjustments.
