Update LCD display on I2C. Specify Columns and up to 4 Rows. Init pin can be used to prevent extra clear displays. Passing null string for a Line will leave the line untouched.
To use the nodes in your project you should have the gweimer/lcd-i2c-init library installed. Use the “File → Add Library” menu item in XOD IDE if you don’t have it yet. See Using libraries for more info.
