For information: I solved my problem.
The solution: when I must change channel, I close (Imports.CloseUnit) communication and restart it.

Thanks

Hi, I'm developer a C# application with PicoScope 3204A. This morning, I have a new problem: when I change acquisition channel, I'll have a crash. I enable channel A and B. For change channel, I set trigger on new channel. This is my code: public bool CollectBlockTriggered(uint timebase, uint sample...

Hi Martin,
yesterday we checked the problem is hardware problem.
Thank you for your patience.

Have a nice day.

Hi Martin,
I check the situation by example console of SDK: same read.

Hi Martin,
I followed your suggestion and I verified that all calls return PICO_OK.
PicoScope software read the same value.

Hi Martin,
I attach the files.

Hi Martin,
I try your suggest and I don't resolve.
If I set Range_5V: read 2.5V .
If I set Range_10V: read 5V
If I set Range_20V: read 10V

I must read 7.5-7.7 V.

Thanks

Hi Martin, Thank you for reply. This problem is very strange, because if I set range:5V and set probe:x10, my application read correctly. I can't set probe x10 for my scope. This is my code: timebase = 20000; _channelSettings[0].range = Imports.Range.Range_20V; CollectBlockImmediate(timebase, 100, 0...

Hi,
is it possibile handle more picoscopes on the same application?

Thanks

Hi, I'm developing a c# application with PicoScope3204 and I have a read problem. I read correctly until 5V (amplitude signal from external board). If I set 7V on external board, I continue to read 5V. I set range: 20V for channel A and B. This is my code: timebase = 20000; CollectBlockImmediate(tim...

Hi Martin,
I finally solved my problem.
I changed my code (very similar at SDK example):
- I open communication (init) with Picoscope by Form
- I create dll object and pass handle as constructor

I think that were thread problems between Form and dll.

Thanks for your patience.

Hi Martin,
can you suggest me something?
Thanks

Hi Martin,
I post my code: part of code of Form and my picoscope dll.
My application works:
- an event call function to handle picoscope
- starts handle form -> dll

I followed your suggest (stop, close...), but I have the same problem.

Can you help me?

Thanks in advance.

Hi Martin,
I used example SDK: PicoSDK\PS3000A\C# console

Hi Martin,
thank you for reply.

I used as example: C:\PicoSDK\PS3000A\C# console.

If you see in previous posts, my code is similar (now I remove Imports.Stop(_handle)).
