Hi!
sorry for my newbie question!
It is possible to use the serial LCD display with the uart3 of the adk board?
Is there some example?
Thank you
this should answer my question!
But I have another question:
Why I have to put the delay(150) even if the init is done?
If I remove that delay the display stay off.

Hi,
Normally,we need some time to reset LCD.So the order “delay(150)” is used to reset.
