crio streaming

[snarf]

Hello,

I'm using the Reference Example for Streaming Data from FPGA to cRIO to Windows found on http://zone.ni.com/devzone/cda/epd/p/id/5919 on a cRIO 9074.

It works fine, the only problem is that after start-up, it takes about 18 seconds before any data is transmitted over TCP. So unless using a huge RT FIFO, some data is lost. After these initial 18 seconds it works perfectly. I have tried changing the different time-outs and FIFO sizes, but nothing seems to have an impact.

Does anyone else have this problem (and maybe even have a solution!)?

Thanks

Hello,

Thank you for posting on National Instruments forum's.

The VI that you use is FPGA>Main?

[snarf]

Yes, it is main.vi.I just added my inputs to it, and it runs properly at 800 ticks.

Hi,

Have you tried using a loop timing? But it will have removed the tick count of the previous loop.

Hello,

The FPGA uses loop timing indeed. You will find the project in attachment.

Thank you for your help.
