ADS122C04EVM: ADS122C04EVM not able to load Device package on Delta Sigma ADC Evaluation Software

ADS122C04EVM: Delta-Sigma ADC Evaluation Software Does Not Connect to EVM

Part Number: ADS122C04EVM
Other Parts Discussed in Thread: ADS122C04

We have installed Delta-Sigma ADC Evaluation Software and the Device package for ADS122C04 (ADS122C04-dvcpkg).  These were installed using Administrator privileges on Windows 10.  The software is not able to connect with the EVM.  Two potential issues that we see are:

1. Windows Device Manager indicates there are no associated drivers for the EVM.  Here's an image showing the Device Manager entry for the EVM.

2.  What is the purpose of the switch S2 on the EVM?  Does closing this switch cause an issue with the EVM?

Please note that we do not see any method of selecting the EVM when the software is started.  This is what appears:

The text in the lower left changes to "Hardware Not Connected.  Ready..." after several seconds.

The EVM is attached to the computer via a USB port located on the motherboard using the supplied USB cable.

    Hi John,

    Welcome to the E2E forum! Development for this software was completed on Win7. I have a Win10 box and I initially had some issues with the driver installation automatically taking place when installing the software. This may have something to do with having Admin rights when installing the software.

    First try installing the drivers by going to C:\Program Files (x86)\Texas Instruments\DSEvalSW\Drivers\Installers folder and then running the BulkUsb_driver_install_x64-v1.0.0.1.msi driver installer. This driver installer contains the bulk signed drivers. The installer should automatically load the proper information into the driver store for the PC.

    As a backup measure, one folder level up in the Drivers folder are the inf files. You could also try manually installing the driver. The inf file to install is usb_dev_bulk.inf and can be installed from the properties box in Device Manager.

    After installing the driver, the Device Manager should show that a proper driver has been installed for the Generic Bulk Device when connecting the cable to the USB.

    Best regards,
    Bob B

    Hello Bob,

    Your first suggestion resolved our problem.  The drivers are now installed and operating correctly.  This is what we see now when looking at the device in Control Panel:

    We are now able to interact with the EVM.

    Thank you for the prompt assistance.
