DAC60096EVM: Driver issue

Part Number: DAC60096EVM

Hello, I am using win 10 and after installing the GUI, I plugged in the SDM-USB-DIG, but the drive was not installed. As a result, when connecting the board through the SDM-USB-DIG to the PC, launch the GUI, I only get the DEMON mode.

Any solutions? Many thanks.

  • Qi,

    Could you please provide an screen capture or describe what the device is being recognized as in the Windows Device Manager? Did you install the GUI with administrator privileges? Installing a driver will frequently require higher level user assess rights in Windows, which may be causing problems.

    Hi Kevin:

    Thanks for the reply.

    I asked our IT support to install the GUI so I can confirm that the software was installed with administrator privileges. Please see the attached screenshot.   COM3 was open for the USB but there is a warning message saying that 'Device Descriptor Request Failed'.

    Thanks for the help.

    Regards,

    Qi

    Hi Qi,

    Please try the recommended installation from this post:

    Hi Paul:

    I followed the post you suggested and updated the driver. Now my PC can find the TI MSP430 USB. However, when connecting the evaluation board, the GUI still shows DEMO mode. 

    Regards,

    Hi Qi,

    Have you been able to verify the software on another PC? Do you have some firewall or other pc software possibly preventing the software from loading?

    Thanks!

    Hi Paul:

    After trying on several PCs in our lab, we manage to find one PC that can make it work using the driver you provided! It must be the firewall but we are not sure what exactly problem is.

    After loading the software, I can see the device is connected. However, I tried to use the default configuration to change the output voltage of different channel, I did not measure any voltage.  I followed the instructions on the manual and I tired different options but no luck... 

    Many thanks for the help.

    Regards,

    Hi Qi,

    What are your supply voltages for the EVM?
  • In reply to Paul_Frost:

    Hi Paul:

    I did not connect any external voltage and reference. 

    I was using the USB to power up the board and using its internal reference. This should be the default setting. I checked the jumpers and they are in the correct position. 

    Regards,

    Hi Qi,

    The DAC60096 (and the EVM) require AVCC and AVSS to be supplied to the device to operate. You will need to provide those supplies for the device to function.

    Thanks!

    Hi Paul:

    Thanks for the advice. I have tested and it works properly. I was confused it with other boards we have. 

    Regards,

    Qi
