Hey. I use Win7. I did all the steps as it is said but when I compile the code I get the error that you can see in the topic. Also, I tried to download and use the file directly, after unzipping and adding it to codeblocks it said:
|13|fatal error: lvgl/lvgl.h: No such file or directory|
#include "lvgl/lvgl.h"
#include "lv_examples/src/lv_demo_widgets/lv_demo_widgets.h"
#include "lv_drivers/win32drv/win32drv.h"

I was wondering if you could help me. Thank you

When I try to compile my project, which contains c++ files, I get an "unknown type name 'namespace'" error.

How do I set CodeBlocks to compile with C++?

Thanks!

Hi, I am trying to use PC simulator for setting up a monochrome display 64x128. Though I setup the lv_conf.h color depth to 1, it's just showing white background color, no buttons are shown (button is present as I get clicks event by clicking randomly on the screen).

I saw this blog:
lvgl/lv_port_pc_eclipse#7
I can't find img_benchmark_bg.c in the environment.

Any idea what I am supposed to do? Please help.

I am developing this for Winstar Oled WEO012864VWPP3N0Y000 monochrome display 128x64. Is there a driver available for this?
Thank you.

With new windows driver (win32drv), which include VersionHelpers.h, I received a "...not found" error. After setup Windows SDK and write file paths in project settings, I received "C:\Program Files\Windows Kits\10\Include\10.0.19041.0\um\winnt.h|1035|error: #error Must define a target architecture.|" error and a few"unknown type name" and "conflicting types".
CodeBlocks 20.03, Windows 7x32, new project lv_sim_codeblocks.

Some people asked me about v8 version of the CodeBlocks repo.

@embeddedt will you have time/interest to update it?

I already tried to update it and it worked but I had ~5 FPS. 🙁

where can I get "lvgl/tests/src/test_fonts/font_1.c"(and font_2.c/font_3.c)?
and the link to "lv_demos" in gitmodules is invalid。

When using lvgl 7.0dev, the buttons added to the window header with the function
'''
lv_win_add_btn(win, LV_SYMBOL_SETTINGS);
'''
are not shown. I have tested my app, and also the lv_ex_win_1 example, and they not show in any of them

Do you have any solution or work around?

code blocks is buggy and is hard to use. Can you use cmake to build this project ????

I use the latest code blocks to open this project and find I can not find the header file and almost all header file can not open..

Hi,

I appreciate it if you update this repo to the latest commits of LVGL and Drivers.

Hi,
Great Lib , Thankyou so much for lib.
I have successfully run PC simulation using Code::Blocks 20.03.
I want to printf output in console for below code (its for example).

#include <stdlib.h>
#include <stdio.h>
static void my_event_cb(lv_obj_t * obj, lv_event_t event)
{
switch(event) {
case LV_EVENT_PRESSED:
printf("Pressed\n");
break;
case LV_EVENT_CLICKED:
printf("Clicked\n");
break;
}
}

for that I have made some steps
project LittlevGL-> right click , then "Properties...", then Tab "Build targets", then change "Type"= "GUI application to Console application"

after above steps , I "Rebuild" the project , now its shows some errors

lv_drivers\win_drv.c|218|undefined reference to CreateBitmap@20'| lv_drivers\win_drv.c|223|undefined reference to CreateCompatibleDC@4'|

||error: ld returned 1 exit status|
||=== Build failed: 8 error(s), 0 warning(s) (0 minute(s), 0 second(s)) ===|

if I reverse all steps back
project LittlevGL-> right click , then "Properties...", then Tab "Build targets", then change "Type"= " Console application to GUI application"
Simulation works fine, but no console or printf text.

Please help me out... I want to check events call function by using console.. Or any other method for checking this please mention. Thanks

Hi, how can I solve these build errors?

It's funny, cause this worked on my home machine, but laptop gives me trouble. Maaaaaybe has something to do with the fact I have cygwin install in the system, but then again I tried to remove it from path and to explicitely set the mingw version of files in the Toolchain setting.

If I go to Header/lv_demos/src/ , Right-Click the lv_demo.h (which is grayed out), go Options->Enable both, then I get

and so on it goes. Somewhere down the road it comes to headers, which are not found even if I do the Options-> Enable both thing.

LVGL version

v8.3.11

What happened?

Conditions:

1. Using the lv_port_win_codeblocks project, the lvgl version is V8.3.11.
2. 32-bit Color depth
3. set full_refresh=0 for partial refresh
4. set direct_mode=1
5. set background transparency
6. use the following code in the main function to repeat the problem

lv_obj_t *scr = lv_scr_act();
lv_obj_set_style_bg_opa(scr, LV_OPA_TRANSP, 0); //Full transparent background
lv_example_anim_2();
lv_example_png_1();

Background transparency needs to be set, otherwise the problem cannot be reproduced！

Normal

Abnormal

How to reproduce?

int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR szCmdLine, int nCmdShow)
{
    /*Initialize LittlevGL*/
    lv_init();

    /*Initialize the HAL for LittlevGL*/
    lv_win32_init(hInstance, SW_SHOWNORMAL, 854, 480, NULL);

    /*Output prompt information to the console, you can also use printf() to print directly*/

HI!
First of all thanks for providing this nice lib and even adding this handy simulation posibilities~!!

More or less from my start using the codeblocks sim I am experiencing some instabilities from exiting my lvgl GUI simulation. I compile and the start the debug session / simulation. When I am going for the next interation (stop sim, recode, restart sim) the GUI simulation does not end, codeblocks freezes. I have to forcefully kill the codeblocks and additionally end the littleVGL.exe in the processes list. (Codeblocks is telling me something like 'codeblocks is in the middle of compiling ... do you really wanna quit?') Then it will give me a new try. This however is not happening all the time but around 50% of me trying to end my simulation.
I tried running codeblocks in admin mode, but no luck.
For sure this can be independently from the codeblocks thing or have something to do with the mingw32/64 installation?
More about my system producing the problem:
it's Win10, what should I add here? Can I provide you some debug system information to get this ruled out? Sorry, but could you assist me in this? (If anything I am more used to debugging embedded stuff rather than Windows apps.)

@kisvegabor
hi,
I want to better maintain this repositorie, can I join it (becom collaborator)?

Hi,

Thank you for this simulator. I try to change the resolution so it can fit for my LCD, but it does not change the window size of the Windows app. I haven't find where we can set that, yet. Any ideas ?

Hi, I try to run the simulator on PC, i use codeblocks-20.03mingw-setup.exe this file to install codeblock, yet after i clone this project and run it. I found that the keyboard not working on the demo, but I can use mouse to click and drag the widgets. But it does not response to any key pressed on my keyboard.

And I try to install the same version codeblocks on another pc, the same problem.

So is this simulator not support keyboard or some other problem? I watch some learning video on youtube, on the simulator inside the video, the keyboard works. And also I try the visual studio version simulator, keyboard works. So just problem on codeblocks?

Hello,

I would like to make new empty Codeblocks project and start from scratch with my project.

Could you please point me to which project I should choose from template or this is not recommendet at all?

Many thanks

It's too difficult to use the WIN32 GUI.

I can't understand how solve the above errors.

Many Thanks

I am completely new to this! What do you mean exactly "also update submodules" I have installed the correct version off codeblocks but the project will not build I assume because of this. Please excuse my ignorance.

please help me

downloaded the project from Github following the instructions but error involving the Win32drv during build.
Seen to be missing declarations of HTOUCHINPUT, IN, In_Opt etc definitions.
Are there settings I need to make or missing files?
Thanks in advance.
James

Followed the tuto, got this while building. Im clueless.

I downloaded the emulator, then add the file in the parent directory, then in the emulator can run successfully, then save and close the emulator, the emulator open again will report CreateProcess No such file or directory

Here is my file directory, the .c file I wrote in the app.
After removing the app file from codeblock, re-saving and closing it, then opening it again, it works correctly, and I can add the app file here to run it, but after adding it, and then opening it again, it continues to report an error!

Translated with DeepL.com (free version)

I tried downloading the codeblocks simulator according to the instructions: Clone the repository first and then update the submodules (I copy & pasted the commands). When I build the project in Codeblocks it fails with some warnings and one error:

"demo.c No such file or directory"

Can someone help me? How do I fix this, I cant figure out where the demo.c is required

Hi,

I see that submodules are all at version 7.5 and recent version of them is 7.11 (v 8 in testing stage) so I would like to know if there is way how update those modules to current version.

Thanks
