I will have to check, but I believe the sampling rate is based on  
using all 8 channels at the same time. It should go up if you have  
fewer active channels, the bottleneck is in the fact that we run both  
the A/D & D/A over the I2C bus.

I anticipate a few improvements to get the sampling rates higher, if  
they can get it to the point where I can sample a decent audio  
waveform (way to go) I will rewrite the scope to be more usable.

If you need a better product write and tell Lee what your priorities  
are, I have been asking for higher sampling rates since I started  
working with them on the project, but it might get pushed ahead if it  
comes from outside the company. What else do you want to see in our  
boards?
