ps4000aSetSimpleTrigger() returned 13
ps4000aSetSimpleTrigger() returned 13
I'm writing a C/C++ application that uses PS4000A API with PS4824. The code is written with EPICS (epics.anl.gov) toolkit version R3.15.5.
If I use a single channel (the rest are ignored by the code) I can operate the PS4824 as expected.
As soon as I start to deal with more channels, I get an error returned from ps4000aSetSimpleTrigger() API call, status == 13:
From PicoStatus.h I can tell it is:
Here some console output from the code I wrote:
For some reason I always get this problem for the sixth channel, out of eight channels that PS4824 supports.
Any ideas? I can share the complete code if it would help..
Thanks!

Re: ps4000aSetSimpleTrigger() returned 13
I think I found the problem. I was not paying close attention to the way my buffers were allocated; turns out I only had one buffer properly allocated and setup with the unit.
I’m curios why it did not fail for channels 2-5, but only for channel 6, though..

We would need to see the full code to be able to comment on that, and as it is now working and you understand the buffering it is probably not worthwhile.
