myRIO FIFO Data Switching

[bjoa]

Hi.

I'm new on LabVIEW and myRIO. I'm designing an acquisition and processing system for Synchros. I've four (4) sinusoidal 400 Hz signals, acquired by four (4) analog inputs implemented on the FPGA, that write the data in a FIFO. On the RT side, I'm reading this data and plot them. The problem that I've is the plot switching, and I think that is a data switching between channels. I tried delaying the writing process, initializing an array and forcing the correct order of writing, increasing the buffer size, and nor of them solve the problem. What could be the problem? The correct order is: Stator 3 -> Reference, Reference -> Stator 1, Stator 1 -> Stator 2 and Stator 2 -> Stator 3

Thanks for your help.

BJoa.

Solved!

In the configure pop-up of the "Open FPGA VI Reference", uncheck the "Run the FPGA VI".

Hi Bjoa

I am doing a similar project as you, I meet the problem when I calculate of input signal. I do not use FPGA to read analog input and want to try. an you share your LabVIEW code?
