PICO_NOT_FOUND

Postby marjan » Tue Dec 10, 2013 12:31 pm

HI,
I am using PicoScope 2204A and I am trying to communicate through Labview 2013 but when I try to run one of your sample program I get this error "Error 5003 occurred at ps2000aOpenUnit" with Possible reason(s):PICO_NOT_FOUND.
Please advice me.
Thanks

Is the scope recognised by our Picoscope 6 software ? and if yes have you closed this down before starting Labview ?

Also my operating system is windows 64-bit. Can the problem be because of that?

Picoscope 6 software will use the 32 bit dll, as it runs as a 32bit application. If your Labview is 64bit then you will need to use the 64 bit dll from the x64 folder within the sdk.

My Labview is 32bit but the operating system is 64bit. I cant use the 64 bit dll from the x64 folder.

I didn't notice this first time round in the original post but you are using ps2000aOpenUnit which comes from the ps2000a SDK, this will not recognise a ps2204a which works with the older driver model of the 2204.

The ps2204a actually requires the ps2000 SDK which can be downloaded from http://www.picotech.com/software.html by selecting PicoScope 2204A, and includes a streaming and block example for Labview.

OK, should I select a specific software version for that?
Thanks

It works, thanks.
Also I need to see the spectrum mode through labview. Is there any labview code for that or do you have any suggestion ?

We have no code for fft with Labview, you will need to check the web for suitable examples.

Hi, Martyn

I also have a similar problem.
When first fime I connect the picoscope to the laptop, run the example code, it works fine. When I stat to test my own code, always show the same error: PICO NOT FUND even I clsoed all the vi code and reopen the same example code again. The LED stays red constantly.
I also reconnect the USB, still not working. From the device manager, can see the picoscope is installed correctly.

The Picoscope I used is: 3404A
The SDK: PS3000asdk_r10_5_0_28
The example code: PicoScope3000aExampleBlock.vi
Can you please help?

Thanks
Li

Don't just close the vi, make sure you press the Stop button first to release the unit from the driver, stopping the vi doesn't release it.

Please note that as you get into developing your own code if you get a crash you will need to close Labview and/or replug the Picoscope to release the driver.

Hi,

I am using PicoScope model 2206A.
First of all, I don't understand why I cannot find this model on the PicoTech website anymore...

Second, I've installed the latest SDK and I'm using ps2000a.dll to communicate with the instrument, but it does not work.
The PicoScope software works fine with it, I must mention.

But when I try to use ATEasy with the ps2000a.dll library, it always returns error #3 (device not found).

Any idea why?

Is there a special SDK for this type of Scope?


Regards,
Alex
