Detailed Description
This is the driver for the Liquid Crystal LCD displays that use the I2C bus.
After creating an instance of this class, first call begin() before anything else. The backlight is on by default, since that is the most likely operating mode in most cases.

lcd_addr I2C slave address of the LCD display. Most likely printed on the LCD circuit board, or look in the supplied LCD documentation. lcd_cols Number of columns your LCD display has. lcd_rows Number of rows your LCD display has. charsize The size in dots that the display has, use LCD_5x10DOTS or LCD_5x8DOTS.

Show the characters on the LCD display, this is the normal behaviour.
This method should only be used after noDisplay() has been used.
