Hi Vincenzo,
you are right, but why are we calculating with 32MByte/s and not with
60MByte/s or something else ?
>From where comes the 32MByte/s ?
USB 2.0 supports a maximum of 60MByte/s. And although our ADC can
handle 32MHz we coudle use 2Byte pro Sample so we get 64MByte/s.
This would be a little more than USB 2.0 can handle. But maybe there
is a solution to get near to 60MByte/s ?
