Generate DC signals with AD-FMCDAQ2-EBZ, no-OS

Hi,

I'm using an AD-FMCDAQ2-EBZ with a kc705 board (no-OS, Microblaze).

I'm trying to generate DC signals first, in order to generate sequences on many voltage levels with the DACs : something like this :

I tried to do this with the dds functions but apparently, DC is cut by filters, right and the dds doesn't seem to be appropriate to generate DC signals? And I wondered if I could write some datas in memories, such the DMA but in the software (in SDK), there is no dac_dma_.. functions?

Could you please explain me how to generate such signals ??

 

Thanks in advance,

 

Alexandre
