Hi Charile:
You might be right. According to the ep93xx family manual, the adc was
originally designed for a touch screen interface.
The maximum sample rates that I could get is 2189s p/s so far, Would
you say this is a reasonable speed or maybe the maximum speed it could
do?
I was planning to use the on-board ADC to sample speech(single word).
If it could really do 2189s p/s, I think, it will be just ok for me.
Anyway, Please let me know if you have the similar samples rate as me.
