Thanks , it was a great help knowing that's all I needed to look at.
I now have the platform and /dev drivers and my userland C code to work with.
Am I correct in thinking that the primary limit on sampling freq is the timer
resolution? It seems it can't do much better than 10kS/s on single channel
readings.
What would be the best strategy for approaching the 100k limit of the MAX chip?
I know I won't get there but I'm interested in the limits of the board.
Oh, and thanks for a nice clean example of how to write a kernel driver. ;)
