Rif.: Syncronize acquisition from C-rio different module (9401,9239)

[FrankyCam]

I wrote the following applications on FPGA

-I acquire nine analogue signal with three delta sigma module NI9239 (just syncronized with one of these as master)

-I implemented SSI protocol with NI9401 to read encoder position

I want

-syncronize the data acquired with analogue module with data from encoder (SSI protocol with NI9401)

-write it in a dma fifo to pass the data from FPGA to c-rio (i've just tried but i loose data)

-send data from cRIO to an host pc for saving (they are a lot of data and i can't save them on c-rio flash memory)

Any suggestion

Hi,

I suggest you to look in the find Examples of LabVIEW and observe the code inside of:

- NI 9401 Digital Port Input and Output - cRIO.lvproj

This project shows how to read from and write to digital input and output ports on a NI 9401 module.

- Basic Synchronizing NI 923x Modules.lvproj

This example demonstrates how to synchronize two NI 923x modules to the same timebase.

- Basic DMA cRIO.lvproj

This project demonstrates a basic application using DMA to transfer data from an FPGA VI to a host VI.

Please feel free to comment the example mentioned.

Regards,

Claudio
