Hi,
I need help with an LCD TFT mcufriend, bought from Aliexpress (chines)
Seller send me datasheet of an ILI9327 he said it is a 16 bits.
The test code (touchscreendemoshield and rectangles) sent by seller work,
but it is all white when using UTFT library of Electronics - Henning Karlsen
I am using Bee 1.0.6 with arduino Atmega 328P.
I tried the UTFT_Demo_400x240 using
UTFT myGLCD(ITDB32WC,A5,A4,A3,A2);
UTFT myGLCD(ILI9327,A5,A4,A3,A2);
But I get nothing.
The only working code is
// ic:ili9327
#define LCD_RD A0
#define LCD_WR A1
#define LCD_RS A2
#define LCD_CS A3
#define LCD_REST A4

Is it possible that is not an 9327?
Anyone can help please?
