Error undefined

[Zeyuzhao]

I got the following error, if I tried to define it, I get a lot more errors.
Using example, avr, 400*240

In file included from E:\Documents\Arduino\libraries\UTFT\UTFT.cpp:55:
E:\Documents\Arduino\libraries\UTFT\/hardware/avr/HW_ATmega328P.h:6: error: no 'void UTFT::LCD_Writ_Bus(char, char, byte)' member function declared in class 'UTFT'

What type of Arduino do you have? This version was prepared for 3.5 display for Arduino Mega used with Arduino Mega.
It seems that you are trying to compile for Uno (Atmega328P) - it is not supported.

I fix code for Uno. You can try to test using:
UTFT myGLCD(NIC35WS,A2,A1,A3,A4); //3.5" TFTLCD for arduino 2560 from mcufriend.com on UNO

Hello!
I have an arduino uno (Atmega328P) and a 3.6 inch TFT LCD ili9327 controller chip. I downloaded the UTFT.zip posted and I wanted to verify if the LCD works as you described. The only change that I made in your code is : UTFT myGLCD(ILI9327,A5,A4,A3,A2); as you cand see in the next code that I just copy

But the code doesn't work. The error is

Error compiling.

Why doesn't work? Can somebody help me?

[Dewsworld]

For me, the code successfully uploads! But I can not make it work. White screen!
