Can LABVIEW read SPI data via USB?

visa?

You need a hardware interface that understands SPI.  The common options I have seen are the USB-8451 or USB-8452, which use NI supplied drivers, or an Arduino which you program to read the SPI bus and send the data to the PC via a serial port.

I have also used the FTDI FT232H (Adafruit has a nice solution).  Requires some DLL interfacing to get it to work.

The driver is ready to use.

I've used the 8451 in the past and had good success.  But for the cheap solution an Arduino running either LIFA, or LINX works great too.  NI's already developed drivers allow for basic control of an Arduino and reading/writing I2C, and SPI is built in.  There isn't as much support if something goes wrong with an Arduino, for instance you can't call up NI and send it back if it doesn't work but can with an 8451.  But for us the risk involved was low enough that an Arduino worked fine.

You should have a USB to SPI converter like aadvark, which will pre existing drivers for communication, so that your development time will be minimized
