DSK6713 + DAC7554

Other Parts Discussed in Thread: DAC7554

Hey!

 

I'm trying to talk to my DAC7554 since a while but I have several problems. I hope you can help me!

I tried using the CCS tool to configure my daughter card which is a DAC 7554 but I don't even get a clock to the daughter card.

With the support tool seems everything be just fine. No warning or error. I have included the new .h files (#include "t7554_fn.h" #include "tidc_api.h") and the compiler does well with this.

I tried to initialize with

 

dc_configure(&Dac7554_1)

 

but it doesn't work. As I said there is no clock or any serial data transfer

 

My program is a sinus generator using edma. With the AIC23 it is already working but I want to give it to my DAC (for future works)

 

Does anybody know if there are special jumpers on the board I have to set / unset ?

    Hans,

    I haven't played with the C6713 DSK very much, but I see a comment in the Technical Reference guide regarding daughtercards that may help: http://c6000.spectrumdigital.com/dsk6713/

    Other than the buffering, most daughter card signals are not modified on the board. However, a few daughter card specific control signals like DC_RESET and DC_DET exist and are accessible through the CPLD DC_REG register. The DSK also multiplexes the McBSP0 and McBSP1 of on-board or external use.  This function is controlled through the CPLD MISC register.
