Hi, I have an Arduino UNO and a LCD and created a LabVIEW VI to display text phrases based on internal calculation and logic. Nothing is displayed in the LCD. What am I doing wrong?

Did you try the shipping examples? Double check your I2C address. Some of the Sain Smart LCD ship with different addresses. Usually its 0x3F or 0x27. Consult you LCD documentation or refer to our help guide.

Let me know if that is the issues.

Ah, yes. That was it. I had the wrong I2C address. Thanks!
