Hi all,

when I execute the code given by logicPD for LCD_graphics, No test pattern is displayed in Graphics LCD,
please guide me

I have the same problem on two different LOGIC PD's ZOOM L138 EVM (one Rev. B and the other Rev. C): the graphic LCD works correctly with the Windows CE and Linux Kernels but not with both the evmomapl138_test_touch and evmomapl138_test_lcd_graphics demo projects available on the same SD cards.

Those projects compile correctly and no error message is displayed on the debugging console, but no image/pattern is displayed on the LCD; it seems that there is some problem with the correct initialization/drive of the corresponding backlight enabling and/or PWM signals.

Is there anyone other than Muthu1983 and me who experimented the same problem?

Can someone of LOGIC PD support team answer this question?

Thanks in advance.
