I'm a new one.Now I have difficulties as the title show.
Who can tell me how the VISA handling the PCI interruption.
Firstly,how to set the VISA Instrument driver so that the VISA can catch the interruption(s).Then,what will the VISA do after the interruption arrived.How and when the VISA will clear the interruption(leave the interupt condition),how and where I can do the IRQ services function?
Actually,I have gone into the VISA instrument driver wizard and do some works,but not as I espected, system always crash down if I enabled the interruption.I'm not sure weather the crash down is caused by interruption or not.
Here are some details about my harewares:
My PCI DAQ was PXI1::13::INSTR,then the interruption flag address is BAR0:0x7C:bit15.Here the 32bits at 0x7C is the interruption enable bits and status bits.Now I 'm just ready to take the BAR0:0x7C:bit15 which stands for the AD buffer half interruption.
Anyone who I explain the VISA interruption handling to me,or who can give any examples.
Thanks a lot for your visit and especially for your help.
