Hi,I am having a problem with data transfer on RT target using global or
local variable.My system configuration is:128 AI channels (4 CRIO 9205)
with 2000 Hz sampling rate.(I am using 3M FPGA and 9014 RT controller)I am
using DMA FIFO for data transfer from target to host (2 DMA FIFOS) and read
100 ms or 200 samples on RT host.I need to transfer data to HOST PC for
analysis.I set up a TCP/IP connection between RT and PC. All works fine
when I read from DMA FIFO and send data to the PC in the same loop .What I
want is to have a communication loop that runs in parallel with main loop
and sends data to the PC. I
tried to transfer data from one loop to other using global or local
variables but I have
encountered a problem of data loss somewhere in that process.My data loss
is always on 200 -th, 400 -th etc.. point (I belive that it has something
to do with reading blocks from FIFO??).What can be the problem. Thank you
in advance!
