Hello:
I have been trying to interface an AD9777 DAC to a BF561 EZ-KIT for too long.
I have used the software that AD supplies, Labview 5.1 .. However, when I try to program the eval board it can affect changes on all the AD9777 registers except register 0, which contains a reset. Can I do writes directly from the SPI interface on the Blackfin extender SPI port to address 0 of the AD9777 and read them back somehow. Only register zero seems to be causing the problem. The SPI control register on the blackfin is at 0xffc00500. Is there any code around to do this.
Thanks
