Hi,

Who has a good example of a frontend program using CAEN V1718 VME-USB bridge and
V1720 FADC? I am trying to set up the DAQ for such a simple system.

I put together a frontend which talks to the VME. However it gets stuck at
"Calibrating" in initialize_equipment().

I'd appreciate some help!

Thanks,
Jianglai

Hi Jianglai,

I don't have an exmaple of using V1718 with V1720, but I have been using V1718 with V792N for a long time.

You may find in the attachment an example frontend program and my drivers for V1718 and V792N written in MVMESTD format. They have to be linked with the CAENVMELib library and other essential MIDAS stuffs.

Regards,
Jimmy
