I am also trying to establish communication to a VL6180X through LabVIEW.

I am using LabVIEW 2013 so I cannot open your 2014 snippets to look at the subVIs. You are using a different set of I2C subVIs than me.

I also have a different breakout board:

Putting a scope on my SDA and SCL lines I have not gotten an acknowledge from the VL6180X yet. Currently I think I might have fried the regulator on my board.

Concerning your issues: the split number takes the high 8 bits and separates it from the low 8 bits but both are in the original format of U16. After the split number subVI you need to convert them to U8 also. Without downloading the I2C VIs I cannot be certain but it should be set up so that the Slave Address that you are putting in as 0x29 needs to be shifted 1 bit to 0x52.
