Hi, i already got an example for LCD showing an image converted to raw pixel ! and know how it works ! (it came with my board, my board is an unpopular lpc1768 that comes with an 3.2inch LCD)

But i have no idea how to make a GUI like i do in Qt, im not expecting to use class or a qt library but to make the screen give a similar result :)

for start im planning to just have a slide and adjust LCD or an LED brightness with it and turn it off with another button ! but i have no idea how to do that! and i googled : "LPC1768 GUI" and got no result ! (also tried "LPC1768 LCD GUI")

Can you tell me where to start? the LCD's specs are:
Resolution: 240 X 320
Controller: SSD1289 (which simply googling its name only gave me 1 related result which i had trouble downloading, i also couldn't download the included datasheet on the board website)
Touch Screen: 4-wire resistive
Pin: 37PIN pitch 1mm
Backlight: 5 LED parallel

Hi Kamhagh,
You may want to use emWin graphics S/W . Please visit
http://www.lpcware.com/content/project/emwin-graphics-library

There is BSP for MCB1700 board which contains LPC1769 (http://www.lpcware.com/content/nxpfile/nxpemwin514mcb1700bsp ).
You will have to build BSP for your board but can take this an example.

SSD1289 is supported in emWin. Please check UM here

Hi Kamhagh,

I am also trying to program a GUI for 3.2 Inch LCD with MCB 1760U board populated with 1768. I have downloaded NXP_emWin514_MCB1700_BSP but i can not run this example becuase of Keil MDK-Lite free Version. do you have anyother example or user Manual for programming LCD with LPC1768?

Thanks.

Hi raomeeran,
Project is also done with IAR and LPCXpresso IDEs. Download LPCxpresso from http://www.lpcware.com/lpcxpresso/download and import project after installing NXP_emWin514_MCB1700_BSP.

hello mc,
thank you very much for your support. I am using keil MCB 1760U board with device LPC 1768. I want to develop a GUI on the LCD of that board. i was creating a simple button on the LCD via segger GUI builder but it gave several Errors, one of them is shown below
.\glcd_test.axf: Error: L6218E: Undefined symbol BUTTON_Create (referred from widget_buttonsimple.o).

Thanks for your Support!
