I2C LCD myRIO 1900

[jonxdc]

Hi! I've been experimenting with myRIO 1900 and with an I2C LCD. I observed the tutorial in youtube about the said operation but I can't seem to find the reason why my text is not displaying into the LCD screen.

The LCD is a 16x2 with an I2C module and seems to be working when it was tested before I bought it. I also made sure of all the connections as well as the specified slave address of the LCD. Shown below are the code and the wiring connection.

Hoping for a solution to this problem!

No, you provided a picture of your code.  We cannot "see" into your Express VI, we cannot try to run your code on a myRIO, we cannot compare your code to I2C examples written for the myRIO.  Do you think it would help us to help you if you attached the Manual/DataSheet of the LCD?

Oh okay sorry for that. Here is the VI file. I sadly don't have the LCD datasheet.

Tutorial on youtube does not work. 

Try the program in this post.

Greetings 
Thank you! Your program works perfectly on my LCD!
I was wondering how did you come up with the code? I would like to better understand so that I would be able to modify it to better suit my needs.
