I am trying to update a test system from windows XP to a newer system. But I am having trouble controlling the AD5304 DAC.
In the windows XP system, the parallel port was used. I am trying to use the National Instruments NI USB-6501.
I know I have the command words correct, but I still can't get it to work.
Just want to be clear, are you able to control the DAC using windows XP or is the problem just apparent on the newer one?
Can you monitor the SPI signals please? Can you also share your schematic?
