Example Program

#include "dsc2.h"
int main(){
 vmeOpenDefaultWindows(); /* Map the VME bus memory (For Linux only.). */
 dsc2Init(0xe00000,0,1);  /* Base memory: Only last 2 HW switches are relevant, 
                             the rest are lost due to shift of address. */
                          /* Memory size per board. */
                          /* Number of boards. */
 dsc2Status(0,0);         /* Board number and flag which is not used. */
 dsc2PrintScalers(0,0xff);/* Board number and printing option */
 return(0);
}

Linux VME support

Brian Moffit from CODA group has setup a directory for software for Intel based VME controllers running Linux. README there is a good introduction to the subject.

/site/coda/2.6.1/extensions/linuxvme

RPMs for VME controllers running Linux located in the directory

/site/coda/2.6.1/extensions/linuxvme/RPMS

Available files are:

gefvme-kmod-common-4.1-0.i386.rpm (Development files)
kmod-gefvme-PAE*.rpm (Kernel module)
