Re: usb connection

Unfortunately I cant see where and when the program gets stuck and it is hard to reproduce. What basically happens, is that I lose the usb connection to the picoscope and the call to get_streaming_last_values_ns gets stuck. When I then restart the PC I sometimes get the windows message, that the pic...

Re: usb connection

I have the same problem with my picoscope 2203. It sometimes (it is hard to reproduce and find a pattern, sometimes after 10 minutes, sometimes after 2 days) looses the connection to the PC, meaning the picoscope is not found by any application (picoscope 6 software, or my own little app) anymore. I...

Re: Longterm streaming fails

Hi Robin,

after a long time a got a chance to test your new dll. (version 2.0.8.32). unfortunately it has the same problem as the old one, so it hangs after 70 minutes. can you check if you posted the right dll?

thanks,
Stefan

Re: Longterm streaming fails

Hi Robin, thanks for your quick answer. I tried the example today with one modification. I changed the parameters. ps2000_run_streaming_ns ( unitOpened.handle, 1, PS2000_US, BUFFER_SIZE_STREAMING, 0, 1, 50000 ) I set the sampling interval to 1 micro second and i don't aggregate the samples. The exam...

Re: Longterm streaming fails

I am seeing a similar problem using the picoscope 2203. After grabbing data for about 70 minutes, the callback function is not called anymore and ps2000_get_streaming_last_values returns always zero. I start streaming using ps2000_run_streaming_ns (handle, 1, PS2000_US, 1024 * 1024, 0, 1, 512*512) a...
