Delay in milliseconds (defaults to 10ms if not set) after a normal command was sent.
The default value is based on the original SparkFun SerLCD library
implementation which assumes 100 kbps I2C configuration. This value
might require tweaking if using I2C at a higher bitrare and/or relativily
high update frequency of the display.
