* \brief specify a daughterboard and subdevice on a daughterboard.
|
|
*
|
|
* In the USRP1, there are two sides, A and B.
|
|
*
|
|
* A daughterboard generally implements a single subdevice, but may in
|
|
* general implement any number of subdevices. At this time, all daughterboards
|
|
* with the exception of the Basic Rx and LF Rx implement a single subdevice.
|
|
*
|
|
* The Basic Rx and LF Rx implement 2 subdevices (soon 3). Subdevice
|
|
* 0 routes input RX-A to the DDC I input and routes a constant zero
|
|
* to the DDC Q input. Similarly, subdevice 1 routes input RX-B to
|
|
* the DDC I input and routes a constant zero to the DDC Q
|
|
* input. Subdevice 2 (when implemented) will route RX-A to the DDC I
|
|
* input and RX-B to the DDC Q input.
