Error 268440457 in ps5000OpenUnit

Post by teegee »

Hi,

I've got a picoscope 5444D with the PicoSDK_64_10.7.20.192 installed and the latest sdk examples from github.
When running Picoscope5000ExampleBlock.vi I'm getting an error 268440457 in ps5000OpenUnit. What am I doing wrong?

I'm running LabVIEW2018 64bit on Windows 10.

I've also installed PicoScope6_r6_14_36 and I can get data from the instrument.

For the 5444D you need to be running the ps5000a examples, https://github.com/picotech/picosdk-ni- ... er/ps5000a , the ones you have are for very old discontinued models.

Thanks Martyn.
I've switched to the 5000a examples. Now I'm getting error 268435457 when I try to open the device without using a serial number. Where do I get the serial number from?

Cheers

The serial number is located below the barcode on the underside of the unit and will look something like AB123/4567

Still no luck even when I pass in the serial number.
The dll returns pico status 268435457
and LabVIEW pops up this error:
Error API function call ps5000aCurrentPowerSource
PICO_INVALID_HANDLE : There is no device with the handle value passed
Error code 12 Decimal 0000000C Hex

Never mind.
Reinstall of the SDK and complete reboot fixed it. Sorry for all the messages :(

Hi Martyn,
I'm trying to package up all dlls required to run my picoscope 5444d so I can deploy an application without the need to install the SDK.
So far I've got ps5000a.dll and ps5000aWrap.dll but I'm getting error 268435457 at OpenUnit. I tried adding some of the other dlls from the SDK/lib folder without success. What am I missing?

You will also need picoipp.dll from the lib folder, and the contents of the system folder.

The system folder contains the low level USB kernel drivers, and the Microsoft driver package executable dpinst.exe

So it's not enough to just include the dlls, I'll also need to run dpinst.exe?

If you are installing and using the device on a Windows 10 system then the kernel drivers can be loaded from Windows Update automatically in response to plugging it in.

For our SDK and the PicoScope applications we use the Microsoft dpinst pre installer just to be sure they are available.

Hi, can you please tell me if (and how) you will manage to package everything needed in a single labview application?
Thank you,
Marco.
