Hello Aditya,

I apologize for the inconvenience. I hope the LDC1101 GUI works for you now.

We are currently working on adding support for the LDC1101 to our new One UI GUI to offer an improved reliability and user experience.

Hello Ben,

Thanks for your response. The GUI does indeed work now.

When I try something and it doesn't work, it's no problem as long as I can quickly (within the tool) get a message saying "this tool is in beta - please look at forum so-and-so" to get it running. It is however frustrating when one has to look what one is doing incorrectly, only to realize that...

I had used the *previous* LDC tool. That "just worked" out of the box (s/w and hardware). With the new one, I am required to install Python (no problems) and NI framework (that takes a lot of time and space and permissions). What was the reason that you chose to integrate the tool into NI's platform? Can't it be done without? Do you plan to release a "lite" version of the LDC evaluation GUI sans any bundled NI software?

Regards,

Aditya

Hi Ben,

P.S. - Before downloading the 1101 GUI, I did first try to communicate with the Ev-Kit with the OneUI. The OneUI does 'recognize' the EvKit (and this makes you think that "it seems to be connected and working"). A "red flag" here would also be nice! (--> announcing that the kit is recognized, but as of yet unsupported).

Regards,

Aditya

Hello Aditya,
I understand that the LDC1101 GUI experience could be improved.
The LDC1101 GUI was developed before we moved to the new One UI GUI. We have moved most devices to the One UI GUI already, and will also add full LDC1101 support for it. The One UI GUI does not require NI software.

I did send your feedback to our software developers, and would like to apologize again for the difficulties that you encountered to get everything running.

I'm having a ton of trouble with this. I have an LDC 1101 EVM, and have installed the new One UI GUI software, as suggested on the website, however nothing in the app works. It says it is connected, but no data is showing up, and none of the support documentation is for this version of the software. The screens for "Device", "EVM", and "Configuration" are completely blank, and nothing shows up in the "Registers" or "Data Streaming" tabs.

I've tried using the old GUI but it says that I have the wrong firmware. I've tried this on two different machines with no success.

Please help. I've wasted way too much time on trying to solve this already.

Hello Aaron,

What version of Windows are you using? Windows 7 is recommended. The OneUI does not yet support the LDC1101; please use the old GUI. Can you post a screen-shot of the message on the wrong FW that the LDC1101 GUI sees on the EVM?

I have seen issues with the old GUI not connecting to the EVM due to some incomplete labview installations. Please try the following:

1) run the GUI one time as an administrator (the GUI needs to create some directories; and it may need to be admin to do that).

2) Try running /cfs-file/__key/communityserver-discussions-components-files/1023/4606.NI_5F00_Visa_5F00_RT_5F00_installer.zip to fix the Labview install.

I tried all of that. Right now, the issue is that the LabVIEW underneath is experiencing some sort of issue, therefore the app won't run (notice the broken arrow).

I'm running Windows 10 Education. I do not currently have a copy of Windows 7/8 lying around.

I also, just tried reinstalling the latest full LV Runtime Engine and the latest NI VISA drivers, with no success (the arrow is still broken).

Hi Aaron,
Just a quick check. Are you running a 64 bit version of Windows 10?

Could you please provide a link to the runtime engine you installed (32/64 bit)?

Varn Khanna,

0 Aaron Fleishman over 8 years ago in reply to Varn Khanna

Yes, running Windows 10 Education 64-bit.

This is the LV RTE I installed: www.ni.com/.../

This is the NI VISA drivers I installed: www.ni.com/.../

0 Varn Khanna over 8 years ago in reply to Aaron Fleishman

Hi Aaron,
Thank you for providing the links. The runtime engine you installed does not support executable built with a 32 bit engine, which I believe what the GUI was built from.

Another thing to note is that Labview Run Time Engine's are not backwards compatible, you will need the RTE version the application was built from with for the .exe file to function correctly.

In addition the GUI installer should have automatically installed the correct version of the RTE, please run the setup as an administrator.

Could you please try installing the following:
http://www.ni.com/download/labview-run-time-engine-2010-sp1/2292/en/

I currently do not have access to a Windows 10 machine and will not be able to verify if this was root cause.

Regards,
Varn.

I uninstalled the 64-bit RTE and installed the 32-bit RTE. Unfortunately, the this did not resolve the issue. The LV block diagram is still broken.

Hello Aaron,

Could you please send us the screenshot of your LDC1101 install directory?

Hello,

this looks correct.

Can you try to run the GUI as an administrator?

Hi Ben,

I also met the same issue when demo EVM. I also download the NI software but still not work.

Any suggestions? Thanks.

Hello Martin,
did you run the LDC1101 GUI as administrator when you tried it? It won't run as a normal user.
