Hello,
I download emWin zip files,but I don't know how to use.
If I don't use RTOS, can it run?

Best regards,
Jacky

No RTOS is required for emWin, and by default it is configured to run without one. The timing is based on a systick timer delay that is used to poll the ADC, and other tasks requiring a delay.

There is very thorough documentation available in the installer packages in the /doc folder, along with a large collection of examples that should be a good starting place to begin using emWin (/Start/Samples).

I hope this helps,
Kevin

Firstly,thanks for Kevin's information.
But I have a error during compile.
That is as follow:
Setup\core_cm3.h(95): error: #5: cannot open source input file "core_cmInstr.h": No such file or directory

How can I modify?

I find the *.h file and add to the needed folder, Now it is ok.
But there is no source code in the GUI_Init().

If you download emWin directly from lpcware, there should be 2 projects, one for Keil (embedded) and the other for Visual Studio (PC).

You should be able to build the Keil project successfully, without much hassle. The Keil project already contains an emWin example that draws graph chart.

kevin,

i have a custom designed board running a 800x600 LCD directly from LPC2148. The SWIM library is running great with the design but when I tried to include the NXP emWin library that is avaliabel on LPCWare "emWin_512_ARM7TDMI_LE.LIB", the program stops at the "GUI_Init()".

after stepping through the program, I found that the functions "LCD_SetSizeEx" and "LCD_SetVSizeEx" are returning "1" and the emWin datasheet mentions that these functions should return "0" when successful.

can u please guide me. i have spent weeks on this now but not moving anywhere.
