Hi,

Anybody managed to make emWin work on a Keil MCB4357 v1.3?

As a base, I'm using the downloaded LPCWare example named "LPC4357-EVB emWin". It uses the Lin driver and uses the SDRAM for memory. That example seems to be for another board (the Hitex one?), so I changed pin attribution for the Backlight.

Upon calling GUI_Init(), my backlight is ON, but I can't put anything on the screen...

Some functions :

{
...
        if (GUI_Init() != 0)
{
goto END;
}

// Do some drawing tests.
GUI_SetBkColor(GUI_RED);
GUI_Clear();
GUI_Delay(1000);
GUI_SetBkColor(GUI_GREEN);
GUI_Clear();
GUI_Delay(1000);
GUI_SetBkColor(GUI_BLUE);
GUI_Clear();
GUI_Delay(1000);

GUI_SetBkColor(GUI_BLACK);
GUI_Clear();
...
}

void LCD_X_Init(void)
{
int i;

// Configure the operating mode for involved pins.

Ok, managed to get code from Keil of their MCB4357 and was missing the SPI part for init. Now it's working.
