Thanks for the Info,
I used that library too, got the same result,
it look like the screen LEDs not good (I can barly see the backlight even with highest setting (lcd.setBrightness(30)).
Thanks for your help.
I did it but it didn't work, All other commands works using 254 code folowd by other commands (like clean, move cursor,turn display on and off,....)
is there any sample code for arduino to check it out?
How can I turn on the backlight using Arduino?
does it need extra power wiring?
