DAC8718 EVM control source code

Donghyun Lee
Prodigy 40 points
Other Parts Discussed in Thread: DAC8718EVM, DAC8718, DAC8534, DXP

Dear TI E2E community,

I am Donghyun Lee from Yonsei Univ. Korea.

I want to control DAC8718EVM by NI Labview in this way. Interface between PC and DAC8718EVM would be some microcontroller such as Arduino Due.
Spec of Arduino Due is here.
Can it be possible? or do you have any other solution or source code to control DAC8718EVM?
Please let me know.
Thank you.

    Donghyun,

    I cannot seem to view the images that you have posted here. Perhaps consider placing these images into a compressed archive and posting that to the forum.

    System spec is here.

    Spec of Arduino due  is here.

    I hope you can see these images.

    In DAC8718EVM user guide document, those words are written.

    I sent an e-mail to blue underlined mail address, but it is resent to me since I am not qualified to send mail to the address...

    Actually, these images is not importnt for explaining my request. Any solution to control DAC8718EVM that can utilize 50 MHz SPI CLK would be fine.

    Do you have software or source code? What interface does support that source code?

    Donghyun,

    That paragraph seems to be a sort of "blanket statement" that was copy / pasted in many EVM User's Guides regardless of if sample code was readily available for the given device.

    Many of our older products do have application notes written that explain and provide sample code for interfacing various TI controller platforms to various TI DACs, you can view that here, unfortunately DAC8718 just isn't one of the parts that has one of these application notes specifically for it. There are two documents about interfacing the DAC8534, which is fairly similar to the DAC8718 (both are 24-bit wide frames and critical edge is falling edge) that might be useful: 

    The DAC8718EVM is supported by our evaluation software called DXP, which should support up to 50MHz SCLK. You can download DXP here. You might be able to use this to meet your needs, though I am not sure what your goal or use case is. The firmware / software source code for this platform is not specific to the DAC8718 and is not likely to be very helpful for use outside of its intended operation in the evaluation software framework.

    Hopefully one of these resources will help you.
