lv_port_pc_eclipse's Introduction

Eclipse Simulator for LVGL (using SDL)

The LVGL is written mainly for microcontrollers and embedded systems however you can run the library on your PC as well without any embedded hardware. The code written on PC can be simply copied when your are using an embedded system.

The PC simulator is cross platform. Windows, Linux and OSX are supported, however on Windows it's easier to get started with a another simulator project.

This project uses Eclipse CDT (as an IDE) and SDL =a low level driver library to open a window, and handle mouse, keyboard etc.)

Get started

Install Packages

On Linux you can easiyl install it the requirements via terminal:

sudo apt-get update && sudo apt-get install -y build-essential libsdl2-dev libsdl2-image-dev libjpeg-dev libpng-dev

Or you can download SDL from https://www.libsdl.org/.

Get this project

Clone this repository and the related submodules to the workspace folder of Eclipse:

git clone --recursive https://github.com/lvgl/lv_port_pc_eclipse

Import the PC simulator project

Open Eclipse CDT
Click File->Import and choose General->Existing project into Workspace
Browse the root directory of the project and click Finish
Build your project and run it

This configures in this project, but if you start a new Eclipse project due to an Eclipse bug you need modify the Assembler command:

In Project properties -> C/C++ build -> Settings -> Cross GCC Assembler -> Command: change as to gcc
On the same place: Cross GCC Assembler -> General -> Assembler flags: add -c

CMake

The following steps can be used with CMake on a Unix-like system. This may also work on other OSes but has not been tested.

Ensure CMake is installed, i.e. the cmake command works on the terminal.
Make a new directory. The name doesn't matter but build will be used for this tutorial.
Type cd build.
Type cmake ... CMake will generate the appropriate build files.
- To build with SDL draw unit, add -DLV_USE_DRAW_SDL=ON to command line
- To build with libpng to support PNG image, add -DLV_USE_LIBPNG=ON to command line
- To build with libjpeg-turbo to support JPEG image, add -DLV_USE_LIBJPEG_TURBO=ON to command line
Type make -j or (more portable) cmake --build . --parallel.

NOTE: --parallel is supported from CMake v3.12 onwards. If you are using an older version of CMake, remove --parallel from the command or use the make option.

The binary will be in ../bin/main, and can be run by typing that command.

Docker

Build the docker container

docker build -t lvgl_simulator .

Run the docker container

docker run lvgl_simulator

GUI with docker is platform dependent. For example, on macOS you can follow this tutorial and run a command similar to:

docker run -e DISPLAY=10.103.56.101:0 lvgl_simulator

Note that on macOS, you may need to enable indirect GLX rendering before starting Xquartz:

defaults write org.macosforge.xquartz.X11 enable_iglx -bool true
open -a Xquartz

For Linux environments with X Server, the following will the docker run command. Note that the first command, xhost + grants access to X server to everyone.

xhost +
docker run -e DISPLAY=$DISPLAY -v /tmp/.X11-unix/:/tmp/.X11-unix:ro -t lvgl_simulator

lv_port_pc_eclipse's Issues

5.1.1 PC Simulation empty files

I have just downloaded the 5.1.1 PC simulation and the lv_drivers, lv_examples and lvgl folders are all empty! When I previously downloaded version 5.1.0 they were not empty and as expected (Although this was via the link from the https://littlevgl.com/download website so maybe this is intentional??)

[v7.0] Keyboard - Can't input more than "max_length" total characters in password mode

I am trying to create a simple T9 keyboard to input a pin number (4 numbers). It has all 10 numbers and a backspace button (LV_SYMBOL_BACKSPACE).

I created a text area on this keyboard with the password mode enabled and a max length of 4 characters.

I have the following issue:

The text area only accepts a total of 4 characters, regardless if I delete any.
So, if I input 4 numbers and then delete any, I can't write any more numbers on it. Unless I delete all the numbers, then I can input only the first number (this is constant - I can always input the number on the first position).
If I input 3 numbers and delete one, I can input 1 more number (totaling 4 inputs) and then I cannot input any more numbers unless I delete every input. In which case I can only input on the first position, as before.
If I input 2 numbers, delete one, input 1 again (3 total), delete one, input 1 (4 total) I reach the same state. Can't input any unless I delete all, then can only input on the first position.

If I don't enable password mode, everything works fine and I can always input up to 4 numbers, regardless if I delete any.
There seems to be an issue between lv_textarea_set_max_length and lv_textarea_set_pwd_mode.

Here's the code I'm running:

const char * map_pin_kb[] = {"1", "2", "3", "\n",
                                               "4", "5", "6", "\n",
                                               "7", "8", "9", "\n",
                                               " ", "0", LV_SYMBOL_BACKSPACE, ""

            1, 1, 1,

	lv_obj_t * ta_pin = lv_textarea_create(parent, NULL);
	lv_obj_add_style(ta_pin, LV_PAGE_PART_BG, &style_ta_pin);
	lv_obj_set_width(ta_pin, 80);
	lv_obj_align(ta_pin, kb_pin, LV_ALIGN_OUT_RIGHT_MID, 20, 4);

NEED FOR HELP

Hello,boys:
I used eclipse CDT to run this code,but got an error.
"../main.c:44:5: error: conflicting types for 'SDL_main'
int main (void)"
How to solve this problem?

lv_label_set_text function bug!

hi , when i use this function like this:
lv_label_set_text(label,"سیب")
this show nothing in button
how can i display a non English word such persian or arabic

Not working on OS X (High Sierra 10.13.6, Eclipse Oxygen)

I've cloned pc_simulator, installed sdl with brew, imported the project into Eclipse Oxygen, and click the build icon.
main.c builds ok, but the link fails.

It seems that objects or libraries are missing.

I tried running make from the root directly, which then built the demo (which doesn't run). I tried adding those objects to the pc_simulator link and it did compile, but again didn't run.

How can I get this running on OS X?

lvgl/lvgl.h : no such file or directory

Hello everyone,
I tried installing the pc simulator for windows. I firstly tried to make it work on eclipse and got the following error :

I then tried to make it work on codeblocks (as I read on an other issue that it was easier to make it work). But same problem again as you can read :

I must say I'm a bit of a newbie here, I mostly code on the arduino ide or in python. What did I do wrong ?

Thanks !

Build instructions with Eclipse produce two errors

Following these instructions from README.md:

Import the PC simulator project
Open Eclipse CDT
Click File->Import and choose General->Existing project into Workspace
Browse the root directory of the project and click Finish
Build your project and run it

Results in two errors:

Errors (2 items)
Description Resource Path Location Type
fatal error: SDL2/SDL.h: No such file or directory keyboard.h /lv_dev_5/lv_drivers/indev line 20 C/C++ Problem
make: *** [lv_examples/lv_tests/lv_test_group/lv_test_group.o] Error 1 lv_dev_5 C/C++ Problem

This was fixed by doing:
sudo apt-get install libsdl2-dev
...and then rebuilding.

Note:
Be sure to select running as a "Local C/C++ application", rather than as a STM application.

_BSD_SOURCE deprecated

@embeddedt
I saw that you added _BSD_SOURCE in 2bb03e7 but I got a wrning for it:

#warning "_BSD_SOURCE and _SVID_SOURCE are deprecated, use _DEFAULT_SOURCE" [-Wcpp]

Should we update it?

video tutorial for pc_simulator_v5_2

hi all,
is there is any video tutorial for pc_simulator_v5_2? - software will definitely will help a lot.as i had tried but not able to install it

[v7.0] Images rotated by default

Hi,
When I try to use images, they all show up slightly rotated by default.
Like this

This is how I'm declaring them:

    lv_img_set_src(img_var, &icon_user);
    lv_obj_set_pos(img_var, 22, 5);

    img_var = lv_img_create(parent, NULL);
    lv_img_set_src(img_var, &icon_manual);
    lv_obj_set_pos(img_var, 256, 3);

    img_var = lv_img_create(parent, NULL);
    lv_img_set_src(img_var, &icon_signal);
    lv_obj_set_pos(img_var, 294, 7);

I've checked the 7.0 API and examples but nothing seems different.

This did not happen before migrating to 7.0, it worked fine. And I've re-uploaded the images just to make sure.

About the task's scheduled period ?

Hi, i have a question about the task's schedule period.

I have seen your code about function : ptask_exec.

Then i understood that the tasks will be execute every ptask_p->period times in millisecond.

But i also have seen your main function code:

while(1) {
        /* Periodically call the ptask handler.
         * It could be done in a timer interrupt or an OS task too.*/
        ptask_handler();
        usleep(5000);

    }

When i use the function: ptask_create to create a task, and parameter two is 5ms.

It seems like that the task will be execute every 25ms.

Did i wrong?

Why you use delay function at there?

Window sometimes doesn't update

The simulator is a very nice tool!

However, sometimes the (SDL) window stops updating. I'm not sure of a clear way of reproducing yet, it works fine most of the time.

When the problem occurs, the window isn't redrawn, e.g. a blinking icon stops blinking, when I turn the mousewheel (encoder), the actual focus changes, but it isn't drawn on the screen.
Only in certain cases the window still does redraw, e.g. when I move my mouse over the minimize/close buttons of the SDL window (i.e. the OS title bar). So if I keep moving the mouse there, the window updates fine, as soon as I stop, the redrawing stops too.

I have to close the application and start it again. Sometimes it then doesn't work for a number of times, sometimes it starts working again. So far, it seems that it either 'just works' after starting and then keeps working, or it 'just doesn't work' after starting, and also stays broken until I restart.

I tried to debug it a bit, and it appears that sdl_refr_qry is still being set to true in monitor_flush() and being 'handled' (and set to false) in monitor_sdl_refr_core(). I compared the render code to SDL examples, and can't spot an obvious error in that either.

It happens both on my own code, and with lv_test_group_1().

So I have no clue why it may be happening...

Display scaling

I am targeting a final display with 240x320 resolution.
On the pc simulator ( eclipse / linux ) the output display window is tiny.

How can I go about scaling the size of the simulator output up?
I would rather not apply a multiplier to the display resolution in lv_conf.h as it will impact expectations regarding final output and negatively impact dev turnaround.

develop Embedded GUI using frame buffer

I want to use this tutorial for embedded Linux frame buffer,
I have encountered two main Issues,
First
It cant be Cross compile easily

second
there is no tutorial for using Linux frame buffer

Suggestion: Visual studio support

Is it possible to support visual studio without sdl library? I know it's possible, just need so effort to port it.

A example project including simulator project is here https://github.com/rossumur/microtouch

This is originally for an atmega32u4, but since it's done very simple, it's easy to adapt! :)

Why am I suggesting this?
To get people to dev easier on the PC simulator by just a few steps to undertake.

Hi,
I have downloaded the PC simulator and I was able to run the demo application on PC. But my end goal was to run the demo application on i.MX6. So, for that I was trying to cross compile the PC simulator project but it was failed. The error is as below:

[v7.0] Can't run sim: "Launching pc_simulator" has encountered a problem. Program file doesn't exist

I'm trying to run the LVGL simulator on dev7.0.
I'm running on ubuntu 18.04 and I've downloaded it through the command line and the used "git checkout dev-7.0".
I then imported the project into Eclipse as the readme says.

I can build the project, but when I try to run it, I get this message:

Any idea why or how I can fix it?

SegFault in Demo

During demo_create()->write_create(), .... Every call to get_glyph_dsc_id() (in lv_font_fmt_txt.c), when trying to assign to fdsc members (last_letter or last_glyph_id), I get a segfault. Fortunately, these are just caching assignments, and commenting out these assignments (there are 4 in total) allows the code to run, but I would like to help others who might run into this.

From digging around the code, it would seem that the pointer font->dsc exists and there is memory at the pointer. Other members at that pointer seem to have valid data, too. However, there seems to be a problem writing to the "last" members at this memory. I just did a test assignment to another part of that struct (cmap_num) and it also segfaulted.

Does anyone have any ideas?

Background: I downloaded (not cloned) the PC simulator code. Had to change #define USE_FBDEV to 0. I am using Eclipse CDT and MinGW64. No other changes.

Can't import to eclipse

Hi, your GUI is very fascinating , so i want to explore it.

Then i follow your guide step by step .

When i want to import project to eclipse, the eclipse warn can't find project file!

And i find your ".gitignore" file is ignored ".cproject" and ".settings" , i think it's why i can't import...

Please fix the bug.Thanks!

Run pc_simulator with WSL + XServer from Windows 10

Hi,

I just wanted to share with you a new way to run simulation within Windows OS, with no need of an IDE.

All we need is:

Windows Subsystem for Linux (WSL from now on). You can check how to install it from here
Install a program to launch Server X within windows, eg: VcXsrv
From WSL install SDL 2 dependencies for Linux as in documentation.
Run xLaunch application installed on step 2 and keep it open.
From WSL, compile project using: $> make.
After compiling finishes, launch demo from WSL: $> ./demo. Now, on xLaunch application we can see the simulated screen.

Note: some other dependencies may be required as indicated on Dockerfile.

Download instructions need a tweak

In "README.md" the instructions for downloading:

git clone https://github.com/littlevgl/proj_pc.git cd proj_pc git submodule update --init

should either be broken into three separate lines, or have semicolons added to the first two commands:

I just tried building from the github master and running on my system (High Sierra, eclipse, sdl2 installed from Homebrew) and got the same crash. The only change I needed to make to get it to build was to remove the #define of USE_FBDEV in lv_drv_conf.h.

It looks like the SDL event pump is still running from the monitor thread.

It looks like this was broken in commit 5e42767 when SDL_PollEvent() was added to monitor_sdl_refr_core().

cannot find -lmingw64

Hello, I have tried to build PC sim. 5.3, but I have follow error:

C:/Program Files/mingw-w64/x86_64-8.1.0-posix-seh-rt_v6-rev0/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/8.1.0/../../../../x86_64-w64-mingw32/bin/ld.exe: cannot find -lmingw64

what's wrong here?

Workaround to run under MacOS

Hi,

I just started using the PC_SIMULATOR under MacOS 10.12.6 and I ran into the following issue.

Using the default source code when running the pc_simulator application the app crashes with the following message

Martins-MacBook-Pro:Debug tinno$ ./pc_simulator

This seems to be due to the fact that you can't Poll from event outside the main thread, at least it seems to be an issue on MacOS, I don't have experience with SDL. Currently monitor.c initialises SDL and monitors for mouse and keyboard events.

To workaround this issue, what I did was.

I modified monitor_init() so that the SDL initialisation is done from main.c thread like so,

void monitor_init(void)
{
	/*Initialize the SDL*/
    SDL_Init(SDL_INIT_VIDEO);

    SDL_SetEventFilter(quit_filter, NULL);

	window = SDL_CreateWindow("TFT Simulator",
		SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED,
		MONITOR_HOR_RES, MONITOR_VER_RES, 0);       /*last param. SDL_WINDOW_BORDERLESS to hide borders*/

	renderer = SDL_CreateRenderer(window, -1, 0);
	texture = SDL_CreateTexture(renderer,
		SDL_PIXELFORMAT_ARGB8888, SDL_TEXTUREACCESS_STATIC, MONITOR_HOR_RES, MONITOR_VER_RES);

	/*Initialize the frame buffer to gray (77 is an empirical value) */
	memset(tft_fb, 77, MONITOR_HOR_RES * MONITOR_VER_RES * sizeof(uint32_t));
	SDL_UpdateTexture(texture, NULL, tft_fb, MONITOR_HOR_RES * sizeof(uint32_t));
	sdl_refr_qry = true;

	SDL_CreateThread(sdl_refr, "sdl_refr", NULL);
	while(sdl_inited == false); /*Wait until 'sdl_refr' initializes the SDL*/
}

I then modified the monitor thread to just do the drawing routines,

static int sdl_refr(void * param)
{
    (void)param;
	sdl_inited = true;

	/*Run until quit event not arrives*/
	while(sdl_quit_qry == false) {

		/*Refresh handling*/
		if(sdl_refr_qry != false) {
            sdl_refr_qry = false;
            SDL_UpdateTexture(texture, NULL, tft_fb, MONITOR_HOR_RES * sizeof(uint32_t));
            SDL_RenderClear(renderer);
            SDL_RenderCopy(renderer, texture, NULL, NULL);
            SDL_RenderPresent(renderer);
		}

		/*Sleep some time*/
		SDL_Delay(SDL_REFR_PERIOD);
	}

	SDL_DestroyTexture(texture);
	SDL_DestroyRenderer(renderer);
	SDL_DestroyWindow(window);
	SDL_Quit();

	exit(0);

	return 0;
}

On the main.c thread I included the polling for mouse and keyboard events like so,

   while(1) {
        /* Periodically call the lv_task handler.
         * It could be done in a timer interrupt or an OS task too.*/
        lv_task_handler();
        usleep(1000);       /*Just to let the system breath*/

	    SDL_Event event;
	    while(SDL_PollEvent(&event)) {
#if USE_MOUSE != 0
            mouse_handler(&event);
#endif

#if USE_KEYBOARD
            keyboard_handler(&event);
#endif
	    }

    }

There is probably a better way to do this, but because I have zero experience with SDL I'm not sure of other solution may apply.

Cheers,
Martin

lv_drv_conf.h` #if and #endif mismatch

The file lv_drv_conf.h has a mismatch between the #if statements at start of file and the corresponding #endif statements at the end of the file.

It's purely a semantic issue. Either the #if or the #endif statements needs to be swapped.

Also, if I edit this file, then I get merge conflicts when pulling changes. I would have thought this file should only exist as a template file to be copied, and should not exist in the repo.

#ifndef LV_DRV_CONF_H
#define LV_DRV_CONF_H
/*
 * COPY THIS FILE AS lv_drv_conf.h
 */

#if 1 /*Set it to "1" to enable the content*/

....

#endif  /*LV_DRV_CONF_H*/

#endif /*End of "Content enable"*/

compile errors on Windows

Trying to compile PC Simulator on Windows 10 after following instruction on https://docs.littlevgl.com/en/html/get-started/pc-simulator.html

BUT ...got compile error due to the fact that lv_drivers/display/fbdev.c has include statements such as

#include <linux/fb.h>
#include <sys/mman.h>
#include <sys/ioctl.h>

Where do you download the include files?

Thx.

I have the SDL2 libraries from brew.

Is it possible to add dev-5.2 branch to pc_simulator?

Hi, the lvgl master is already updated to dev-5.2 but it looks like pc_simulator version still not have dev-5.2 changes.
If someone who experiment with pc_simulator version will not get the dev-5.2 in this case (even for PR).
Could you please let me know whether this can be updated accordingly.

Version for Codeblocks

Hello,
I have just ported Eclipse project to Codevision, may be it would be interested for other users?
Codeblocks seems to be more quicky and reliable and doesn't need anything to be installed, MinGW comes already with the software and you need only SDL2 includes and libraries to be able to run simulation project.
Waiting for your reply.

Extra #include "lvgl/lvgl.h" in lv_tutorial_responsive.c causes build issues

The source file, lv_examples/lv_tutorial/9_responsive/lv_tutorial_responsive.c, has #include "lvgl/lvgl.h", while the associated header has the correct #include "../../../lvgl/lvgl.h".

Removing the include statement from the source file fixes the issue.
