AD5060 Eval LabVIEW driver not working.

Hi,

I'm using the AD5060 Eval system and all works well when I use the supplied driver application, but when I switch to the LV driver I cannot get anything out of the device. The LV driver is not reporting any errors and it does find the board. I hooked up a logic analyzer to the 3 TP's on the eval board and can see the SPI transactions if I use the application but nothing if I use LV. I also want to drive the device with dynamic data... sine etc. rather than just set points hence wanting to use the LV driver. Has anyone seen this behavior from the LV driver and have they managed to get it working correctly?

Thanks,

Nick

    Hi Nick,

    this is something completely different...

    to generate a proper AC signal, you will need to use a completely hardware interface... in other words, the cypress controller is not deterministic so, each new sample will be transfer at completely random time... this will degraded any performance that the part can achieve.

    I'll recommend to use an external controller for this purpose.
