AD9106:How to output the waves that saved in the SRAM of AD9106?

Hi,

       I'm using STM32 to control AD9106 to generate the wave that saved in the SRAM. I have succeeded in writing data to SRAM, but I failed to output the data. Which registers should I configure? Besides, does the sequence of the registers influence the output?

       Thanks, I'm hope for your reply.

  • Hi -

    Here is an example register value (.regval) and a SRAM vector that will produce a guassian wavrform at the DAC outputs that come from data stored in SRAM.

    Thanks

  • Hello,

    I am experiencing the same problem, using the same microcontroller family. 

    Were you able to output the stored data?

    I have been able to write to the SRAM and read it out through UART, however I am unable to generate the signal. I have tried the suggest register call out yet still no luck. I have been able to generate the prestored signals (sine and sawtooth) but nothing from the SRAM.

    What are the uniquely different register for generating a signal from SRAM versus generating a signal from the prestored signals? 

    Thanks,
