    Hi, 
    

    So I am trying to generate output from this DAC but the problem is software isn't responding at all. Once when I pressed measure output voltages it gave positive +9.95V in all outputs but after that nothing is working and I a unable to use this software. Please help me out how to get this running. Also, I want to generate voltages using STM in future, guide me on that part too. Thanks in Advance.

      Hi,
      

      Try powering down and setting LK7 to A for USB control, LK6 to A for USB‑powered digital logic, and LK9 to B for bipolar output on the evaluation board . Then try powering up DVCC via USB before applying the AVDD and AVSS analog supplies to avoid undefined internal states . After that, try launching the AD5754R software and checking in Windows Device Manager that the board enumerates as “AD5754R Evaluation Board” with no warnings so the software can communicate and you can measure or program outputs.
      

      For STM32 control later, move LK7 to B, wiring your SPI, LDAC, and GND signals to J8, and sending the standard 24‑bit SPI commands to configure ranges (for example, 0x080004 for ±10 V) and power up (for example, 0x10041F) before writing voltage codes like 0x004000.
      

      Best Regards,
      

      Den
