How to communicate to an I2C device

[Brzhou]

Hi Sir, 

Okay, i see, because the USB-8452 is higher as ~3000usd.

Let me check this FT232H tool.

Thanks.

Where did you get that 3000$ US value from? The price in Euro is around 1000, and that is already with a significant markup to the domestic US price.

If NI would start asking such prices I guess it gets time to sell our own version of it.

I have checked via taobao, it is around 16000RMB.

I have searched some solutions, another possbility is that Labview LINX + arduino.

The LINX tool has I2C, SPI interface, I guess it uses arduino to communicate with I2C directly.

This looks much cheaper, not sure someone tried this.

Thanks.

Skip that LINX from this sentence!

Do the SPI/I²C between your sensor and the Arduino using any of those available code libraries for Arduino.

Then just do serial communication between Arduino and your (LabVIEW) computer…

Hi GerdW,

Understand the point.

Need some library or say driver to convert my serial port commands to i2c commands.

But I am not familiar to generate those kind of driver, that is the reason i search a mature solution.

Thanks.
