|
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.
