TI AFE4490 on labview

Hello,

I am currently working on the following project:
With an acquisition card (AFE4490) manufactured by TI (they don't broadcast labview source code , or the driver for use directly ), I should be able to process the values in real time in labview . The card is connected to the computer via a USB port, but the chip communicates using a SPI port.
To do this, they gave me the datasheet of this card and the main operation is to write the different registers in this card from labview . I have a sheet with 30 registers with  addresses and corresponding reading and writing addresses.
For example, after the initialization of the card, the first operation is LED2STC , address 0x01 and address read / write 0x0017C0 .
The doc says that the chip has 32 bits , it uses the first 8 to write the address and uses the 24 other to write the reading and writing addresses.
So I wanted to know how it was possible to enter these registers in labview ?

Attached a sheet with the list of the registers.

Regards,


Damien

NI offers the 8451 for SPI communication.

Hello,


Thank you for your reply but I'm in charge of this project over an unpaid formation, so I thought more programming ideas in labview directly. I saw a feature that allowed to write a 32-bit block, that is what I want, but I don't know how to wire it.

 

Regards,

 

Damien

LabVIEW is software and you'll need some sort of hardware. What are you planning on using?

How are you planning to physically connect to the spi port?

The chip is integrated into the capture card and is connected to the computer via USB.

Sorry, I thought you meant it had a separate port.

You will have to get details on the USB communication from TI. Did they provide anything at all on how to connect and read/write to it? How does the device appear on Windows device manager?

Yes here is the datasheet, page 47 to 73 it explains how to read and write data, but there is no link with Labview...

 

There is a software that was installed with the card, but it does not meet expectations because it does not allow to take continuous measurements, unlike Labview.
I use Measurement and Automation software that allows me to see the TI card and access its properties and see its attributes.

You attached the data sheet for a component - not a board with a USB port. You need something that explains the serial communication that the USB is emulating. Contact TI for the correct manual.
