Any LabView Example code of using NI USB-8451 to write data to i2c device?

[cools104]

I have used the 8451 integrated example (General I2C Wirte.vi ) , it failed to write any data to slave device.
But it could read data properly.

Is there any wrongs in the example (General I2C Wirte.vi)? why I fail to write?
I fill the data in red block, is there any wrong?

By the way, what is the target page size?
(use default value 128?)

Cools,

What device are you trying to communicate to?  Sometimes the what do I need to write questions are very device specific for I2C and it would help knowing what you are writing to.

Also, are you seeing any errors when trying to write?
