Oh sure, getting eabi sorted is the primary objective, including porting our
software to the new ADC driver. After that using the FPU would be nice too if
the hardware bugs have been worked around now. Kudos to those who have sorted
all this out.
Do you have any boards with the MAX197 ADC? The chip's sample rate is 6us from
memory and I'd like to get something better than the lamentable 10ms that is
possible with the standard installation.
These boards would be whole lot more useful with a sensible sample rate.
