LABVIEW LINX _PRESSURE SENSOR I2C COMMUNICATION

[NTS96]

Hello,

I am developing a code for reading the Honeywell pressure sensor (sensor model No - T005PG2A3) data in the LABVIEW LINX module via I2C communication established between the pressure sensor and the Arduino UNO board. I am trying to read the first two bytes of pressure sensor data. But the sensor output reading is not showing any change. I am posting the VI that I am working on, together with the technical notes on  I2C Communications with Honeywell Digital Output Pressure Sensors. Could you please suggest what's wrong with my code ?

A couple of points:

• Use Windows to compress your Project Folder to a .zip file (right-click folder, "Send to:", "Compressed (zipped) Folder").  Many (most?) LabVIEW users don't use Roshal Archives.
• None of the I2C files were saved with your Project.  They all appear to be "Maker-Hub" (Linx?) files.  This is the Forum for general LabVIEW questions -- perhaps the "Hobbyist Toolkit" Board (under "Additional NI Products Boards") would be a better place for this question.

If this was a LabVIEW question about software using serial communication (the old-fashioned way, 9600 baud and all that), I'd suggest opening MAX, opening the COM port and running some VISA tests (like setting VISA up with Baud rate and other settings, and sending a Test Message and seeing what response I got).  I've done a bit with SPI (using an NI "SPI I/O" device), but so far, no I2C ...
