USB to GPIO EVM, Windows 7 64-bit

Referencing another post, (link below) has there been any changes with the driver for the USB to GPIO EVM to support 64-bit Windows?

http://e2e.ti.com/support/dlp__mems_micro-electro-mechanical_systems/f/94/t/112157.aspx

  • USB-to-GPIO shows up as HID device within Windows and doesn't require any additional driver, at least as far as I know.

    Are you having an issue with connecting it?

    WinXP 64 or WIN7/WIN8 64?

  • Ignore the question on windows version, just noticed the title.

  • Gents, Actually I have the same problem. The adapter installs fine with no error. No extra drivers needed. No yellow question mark in device manager.

    When executing the GUI for the USB-to-GPIO adapter it tells in the status line at the bottom of the window that  there is no adapter.

    I have Windows 7 64-bit on a Dell E6530 laptop. The .NET framework for Win 7 is 4.5.

    Is there a solution? Thanks for help!

  • I'm running 64-bit WIN7 without issue.

    I have a Toshiba but most TIers have Dell E series laptops.

    What hardware are you attempting to communicate with and which GUI interface, Fusion Digital Power Designer or something else?

    Is the USB Adapter connected through a USB hub/switch, try connecting it directly to the system.

  • For now I just connected the adapter http://www.ti.com/tool/usb-to-gpio and tried the software downloadable from that page. Unzipping the contents to a folder on desktop (path: \USB Interface Adapter Software\USB Interface Adapter GUI-v1.10\bin\) and executing by doubleclicking USB SAA GUI.exe there.

    Got this window. Please note the "Adapter not attached" message at the bottom of the window. As a starting exercise I just wanted to set the pull-up resistors to 2.2k. Doing so by pressing Set lets a popup appear:

  • Need to mention that I'm connecting the adapter directly to the system with no hub in between. According to Windows (device manager) and also visible by the adapter's green light it is enumerated correctly.

  • I see you are using the generic GUI from the USB-to-GPIO webpage.  I can't speak to this particular software, other than it does appear to only support WinXP.

    Digital Power has its own GUI interface (Fusion Digital Power Designer) which is specific to the devices we support:

    http://www.ti.com/tool/fusion_digital_power_designer

    But there is a seperate tool associated with the Fusion GUI that should have very similar functionality to the generic USB-to-GPIO interface and it is not specific to the TI digital parts.

    It is called the SMBus & I2C & SAA Degub Tool and can be found in the Tools folder under the Fusion Digital Power Designer software folder after loading this interface.  This is WIN7/8 compliant.

     

     

     

     

  • Hi 

    I want "SMBus & I2C & SAA Degub Tool" and try to install Fusion Digital Power Designer software.

    But can't find it in Fusion Digital Power Designer software folder.

    Please send a direct link to me for it.

    Thanks

  • It is part of the complete installation of the Fusion Digital Power Designer.

    Then you will find it in the Tools folder:

    Thanks for your help.

    Do we need any driver for USB device?
    The FUSION DIGITAL POWER DESIGNER has been installed and restart PC.
    The SW seen hang up(forever) to looking for USB series adaptor.
    It will resum after disconnect USB adaptor.
    And hang up again when reconnect USB adaptor.

    Please let me know more.

    SAA #1: PollPmbusSignalLines: USB/SAA ERROR

  • After plugging in the USB-to-GPIO adapter, it should show up as a standard HID (Human Interface Device) component in the Device Manager, no additional driver required.

    Are you connecting the USB cable directly to the host system or through a USB hub, I've never experienced a problem doing this but I've heard that this could be a problem.

    PC can see it(adaptor), but still not work.

    I have double check that It can read/ control bq24195EVM.

    The adaptor should be function correctly.

    Please let me know your comment.

    PS: My PC is 32bit XP

  • Hello,

    I'm finding some troubles when using "SMBus & I2C & SAA Degub Tool" with my USB Interface Adapter. In my case the application freezes during "Looking for USB Serial Adapter". If try to use the adapter with the BQ2416x EVM software, it works fine.

    The firmware version installed is 49.2.2.

    Also if i detach the adaptor the  "SMBus & I2C & SAA Degub Tool" opens  with some errors like below:

    Can somebody help me with this?

  • The USB-to-GPIO adapter doesn't ship with FW version 49.2.2, I'm assuming the BQ2416x EVM software must be loading this version since that device is operating correctly.

    Please refer to the following post for an explanation on downloading a FW version to the USB-to-GPIO adapter which is supported by the Fusion GUI (I have not tried updating from 49.2.2 as I've never seen this FW version before but I expect it will work).

  • I just confirmed the BQ2416x EVM software does in fact overwrite the shipping FW and that it can be restored to a 10.x.x version.
    One thing is required, after launching the USB Adapter Firmware Download Tool it will not find the adapter while scanning, unplug adapter from USB and FW load screen comes up, reconnect adapter to USB and then continue procedure.
