    Thread Summary
    
                The user is using STM32 to control AD9106 for generating a waveform from SRAM. The final answer provides an example of register values to produce a Gaussian waveform from SRAM data. The accompanying answer highlights the need to configure specific registers differently for SRAM versus prestored signals and suggests checking the Trigger pin.

    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,
        

        Owen
