I am experiencing problems with viMoveIn16 function with PCI-MXI-2 on Linux.
I was trun off DMA.
I used viMoveIn16 function for read directly local memory.
So, I try to read more then 16 points. but the data was wrong.
signed short readVal13, readVal24;
err = viMoveIn16(id, VI_A16_SPACE, VXI_FIFO_HIGH, 16, readVal13);
err = viMoveIn16(id, VI_A16_SPACE, VXI_FIFO_LOW, 16, readVal24);
And,I got error message "ERROR = Invalid length specified." when I try to read more then 20 points.
and then I got wrong data.
What's the problem ?
What can I read maximum counts of viMoveIn16 function?
Do I need another setting for VXI ?
