Hi,
I am using Picoscope5243A, in which i require runblock function to be implemented in Block mode, but somehow i am getting PICO_SEGMENT_OUT_OF_RANGE error(error no 0x26).

RunBlock(handle, 0, samplecount, timebase, out timeIndisposed,0, null, IntPtr.Zero);

Please suggest any suggestion .

Thanks
Sumit

Your colleague should have received some example code through our Helpdesk

Hi,
I am using PicoSope 5443A and trying to perform measurements using Qt5.3 with msc2010 compiler and win7.
In my program I successfully opened the scope and made the LED flash.
I continued to add a simple trigger and that is ok, too.
When adding

Code: Select all

    // initiate measurement
    int timeIndisposedMs;
    status |= ps5000aRunBlock(handle,
                              50,                   // 50 samples pretrigger
                              SAMPLENUM-50,         // and 450 samples after trigger
                              4,                    // maximum speed allowed for 4 channels = 16ns
                              &timeIndisposedMs,    // get back delay until hot.
                              0,                    // use first (and only) memeory block
                              NULL,                 // we use polling for Data acquisition -> no callback
                              NULL);                // and -> no Data buffer pointer

the system still compiles, but the linker says:

missing external symbol "__imp__ps5000aRunBlock@32"

Please pinpoint me to the problem, if possible,

thx, Uwe

p.s. Maybe it is important that the Executable is a win32 app though the system is a Win64 thus still there should not be a difference between header-file, lib and dll..??
p.p.s. I installed all picoscope software from scratch this monday.

Hi Uwe,

We are aware that version 10.5.1.1 of the PS5000a SDK contains incorrect lib files which is likely to be causing the issue.

Could you please e-mail support@picotech.com indicating if you require a 32-bit or 64-bit version and we can send this out to you.

This should be fixed in the next SDK release.

Regards,

Update:
by temporarily removing the associated .lib and .h files I ensured that the library file used by the linker and the API header file is the file I copied from the downloaded archive.

ps5000a.lib file from Feb.12.2013 (10:52)
ps5000aApi.h from Sept.11

2014 (14:31)

is it possible that these do not match?

Hi Uwe,

You are correct, the dates do not match in SDK version 10.5.1.1.

It's possible that there were changes made to the header file but the lib file was not updated - we will make sure that the next SDK release has the updated lib file.

I have sent the file plus the ps5000a.dll from the PicoScope 6.10.6 installation directory via your support e-mail ticket.

Hello,

I am stuck with the same Problem. Is it possible that you send me the correct .lib file, too?

Best regards,
Daniel

Hi,

I believe I am running into similar problems using the supplied SDK 10.5.2.1 with Visual Studios C++ 2013. The current .lib provided is still dated 2/12/13 while the header is 9/11/2014 and dll is 12/11/2014. Specifically what I am running into is

Code: Select all

Hi Jason,

Could you please e-mail support@picotech.com and indicate if you require a 32-bit or 64-bit lib file?

We will make a request for a new SDK build with the correct lib file as well.
