Site / Pin addresses for DAC on NI Digital Electronics Board

[Bret Wood]

My advanced DE students are trying to build a circuit capable of communicating with the DAC on the NI Digital Electronics Board.

We have things to the point where we have a solid data stream, synchronized with our serial clock, and timed correctly relative to the DAC_CS pulse.  It all looks great on our oscilloscope. The one thing we are missing is the sites the signals are supposed to be mapped to in the Xilinx PlanAhead software.

For example, LED0 is C11, LED1 is D11, SW0 is J11, SW1 is J12, etc...

The signals we need to be able to control on the DAC are:

DAC_CLR, DAC_CS, SCK, and SDI.

Thanks,

Ooops, found it myself.

The master file was C:\Program Files\National Instruments\Circuit Design Suite 11.0\pldconfig\DEFB.ucf

The DAC related locations are:

SCK           R4

SDI            P3

DAC_CS    N12

DAC_CLR  P13

Hope this helps someone else too.
