On 8/10/10 JK asked, “I compiled the Source Code v1.04 after changing the Config_App.h to
#define UEZ_DEFAULT_LCD_CONFIG LCD_CONFIG_OKAYA_QVGA_3x5_LCDC_3_5
In Arm Flash Release mode, after flashing, the LCD goes all white before going completely Dark. LCD beeps with error on touch. Is there a Back-light Calibration I need to do?
With the original Demo code it worked fine. The Dark LCD problem happened only after recompiling code.”

Answered:
Sounds like you have a different LCD Carrier board. The LCD CARRIER 3-5 has its backlight control the opposite of the Rev 2 hardware.
For now, try using
#define UEZ_DEFAULT_LCD_CONFIG LCD_CONFIG_TOSHIBA_QVGA_LCDC_REV2
This should make the backlight come on properly.
