Somebody please sanity check me here.  I'm fooling around with an ADC24 which 
supposedly has a 1 msps sample rate.  Yet I can't seem to suck out the data 
fast enough to keep up with it in normal C code.  In fact the best I seem to be 
able to do is 100 ksps.  This is with a version of the recent ADC16 C source 
code that Technologic posted about a week ago.  The changes being the addresses 
of various registers.  And that sample rate is purely copying the data from the 
FIFO to another storage area for later analysis.  So why would the board be 
able to run ten times faster but you could never run it that fast?  Is this a 
case where using a device driver would make it faster or writing raw assembler 
code?
