RobotGeek I2C LCD Special Characters

The following table shows the relation between a byte value sent to the RobotGeek I2C LCD and the character displayed on the LCD.

These characters can be sent to the display using the lcd.write() function. For example

lcd.write(126)

will send an 'arrow' character() to the display

To see representations of what each character will look like on the LCD display, see page 17 of the HD44780 Datasheet. The RobotGeek LCD uses the Japanese Standard Font (ROM Code: A00). The numbers in red represent the top character in each column of the character table.

For more information see the lcd.write() function on the RobotGeek I2C LCD Library page.
