Need help with VM-USB for Linux Data Acquisition System

Postby rlmacdonald » Fri Nov 18, 2011 6:56 pm

Hi All,
I want to use a VM-USB to connect to fedora operating system in hopes to generate histograms from a data acquisition system that I'm using to detect cosmic rays using sodium iodide detectors. All the hardware is set up properly, however I don't know much about the software end of things.
So far, i understand i need to;

move the libxx_usb.so file to usr/lib/

move xx_usb.h to /usr/include/

install libusb and libusb-dev

compile by "gcc -shard -o libxxusb.so libxxusb.c -lusb"

but after doing these things I don't have much of an idea of what to do.
Any help is greatly appreciated. I am very new to this.
Thank you.

Hi Lee,
In order to histogram enregies from your sodium iodide detector pulses you have to write a program to read out your ADC's, collect and histogram the data and then plot them.
This program will strongly depend on the used ADC.
It may be an easier task to use existing DAQ programs like the MSU NSCL DAQ software (see at http://sourceforge.net/projects/nscldaq/. This open source software is linux based and includes data acquisition, histogramming and graphics display.
