Waveform display is very slow, getting data is very slow

Postby guoduhua » Wed Nov 30, 2016 6:32 pm

I have a problem,very important,very urgent,please help me. :(
I use the PicoScope 5243B,connect the signal generator.I developed the program, according to your example:streamDataHandler function,and has displayed the waveform.
But the speed of graphics update is very slow, the speed of data acquisition is very slow, need to wait 30 seconds or 60 seconds to show a waveform.
That is why? :cry: Answer me please. Thank you very much!

Please can you try collecting and displaying a similar amount of data in PicoScope software with the same trigger conditions / AWG settings. If PicoScope is working normally then we can rule out any hardware or driver issues and the problem seems likely to be in the code you have written.

We will need either a copy of the code or more details about what it is doing in order to help further.

Having you managed to perform the test in PicoScope 6 using similar settings ?

What version of the driver are you using with your code ?
