Problems with ps5000aSetDeviceResolution (5444B device)

Post by MikeNuke »

Hi!
I did changes in my labview software we use to acquire data in order to add the possibility of using also a 5444B device.

All the libraries and subVIs were substituted and everything works fine.

Since one of the best things with this device is the flexible resolution, I also added a subVI to manage it, and this is not working.
The ps5000aSetDeviceResolution call library reports a PICO_INVALID_HANDLE error (5012).

Since all the other libraries work, I don't understand what could be wrong with the handle. I can set the resolution at the beginning when I open the device, but changing it while running could be very useful...

I attach the not-working subVI.

Thanks!

Hi Mike,

The issue is that you are calling handle as a pointer to value,
when you should be using just the value.

The pointer to the handle is only used when opening the device.

Thanks,
