Hi all I am using the 7831R FPGA device on a PXI-1042 platform for data logging.
Currently i am acquiring one digital input and four analog inputs for my application.
I am writing the four analog inputs, along with the time stamp, to a memory location (FIFO) in the FPGA vi and then accessing back them using DMA on the host.
Then, i am de-interlacing the array and writing it to a spreadsheet.
Now, the problem i am facing is, "there is a suden data loss at regular instants in the acquired excel file". My sampling time is 30 micro seconds.
I am attatching the FPGA and Host VI's.
I would be glad is someone could help me out of this. I have been trying for a long time now, by changing the sample time, depth of the data etc., but could not eliminate the data loss.
Thank You
