Part Number: LDC1000EVM

Hello.

I am trying to use "LDC1000-SW" (LDC1000_EVM_GUI_1_0_4_1, downloaded from http://www.ti.com/litv/zip/snac058) with LDC1000EVM.

During installation of the included driver ("Texas Instruments (usbser) Ports (02/11/...") I got an error notification ("failed"). After starting the "LDC1000-SW" I cannot connect to the device. Unfortunately, I was not able to update the driver at Windows Device Manager successfully. I got following message: "The best drivers for the device are already installed." (Windows is using "usbser.sys"). I cannot change this. I have attached some screenshots. Please take a look at them.

Earlier I tried to use latest "Sensing Solutions EVM GUI". But I faced the same problem as in https://e2e.ti.com/support/sensors/f/1023/t/478818?Sensing-solutions-EVM-GUI-toggling-not-connected-connected-with-both-LDC1000EVM-and-LDC1614EVM.

Best regards,

Patrick

Patrick,

Thanks for reaching out. The LDC1000 is an obsoleted device. It was replaced with LDC1001. For basic debugging please try the following steps:
- To launch the GUI, right click and select "run as administrator"
- Enter Device manager, right click on the EVM, and select Uninstall device. Then disconnect and reconnect the EVM.
- Uninstall the GUI and driver completely, and then re-install using "run as administrator"
- Connect the EVM prior to launching the GUI
- Make sure you are attempting to use the latest software https://www.ti.com/lit/zip/snoc028
If those don't help, you may want to also refer to the following E2E threads for assistance:

Hello Scott,

Thanks for your assistance. Since LDC1000 is an obsoleted device, there is no point in continuing with this. I will start to use a newer one, e.g. LDC1312(EVM), in the near future (some pieces are already ordered). My expectation is that the latest GUI (Sensing Solutions EVM GUI-1.10.0) will work properly with it.

BR,

Patrick
