Description

The raw data accessor is using the SSDN channel as the ADC channel. This is wrong because the SSDN channel identifies the ADC not the ADC channel.

The ADC channel number (0-15) is now encoded in the device's SSDN misc field. Therefor, the SSDN for a raw data device should now look something like this: 000B/0020/000cc/00aa (where cc = ADC channel and aa = ADC identifier).

Created Z:CIARW2 and verified with a sine wave hooked up to channel 2 on nm2rfi.

Deployed at the development and test level.

However, I noticed that the firmware seems to have the channel data separation fixed at 64 K-samples. E-mailed Alexei and Ning to figure out how we can expand that.
