搭建LVGL V8版本PC VS2019仿真工程

下载lvgl,lvgl_drives,lvgl_demos相关文件

点击下载 提取码：hmry

新建一个文件夹lvgl_v8_similator_vs2019，再在此文件目录下创建一个VS2019控制台工程

选择控制台应用，点击下一步

工程名输入lvgl_similator,路径选择到lvgl_v8_similator_vs2019目录，最后点击创建

在lvgl_similator文件夹下创建一个文件夹lvgl_folder

将下载的lvgl,lvgl_drivers,lvgl_demos分别解压到lvgl_v8_similator_vs2019\lvgl_similator\lvgl_folder目录下

在lvgl_similator工程下分别创建lvgl,lvgl_drivers,lvgl_demos项，并分别加入lvgl,lvgl_driver,lvgl_demoes目录下所有文件到工程

将lvgl_similator_v8_vs2019\lvgl_similator\lvgl_folder\lv_drivers目录下的lv_drv_conf_template.h文件复制到上一级目录，并重命名为lv_drv_conf.h，将lvgl_v8_similator_vs2019\lvgl_similator\lvgl_folder\lv_demos目录下的lv_demo_conf_template.h文件复制上一级目录，并重命名为lv_demo_conf.h，将lvgl_v8_similator_vs2019\lvgl_similator\lvgl_folder\lvgl目录下的lv_conf_template.h文件复制到上一级目录，并重命名为lv_conf.h

分别将lv_conf.h,lv_drv_conf.h,lv_demo_conf.h中的#if 0 改成#if 1

将lvgl_similator.cpp中更换成以下内容

#include 


#if _MSC_VER >= 1200
// Disable compilation warnings.
#pragma warning(push)
// nonstandard extension used : bit field types other than int
#pragma warning(disable:4214)
// 'conversion' conversion from 'type1' to 'type2', possible loss of data
#pragma warning(disable:4244)
#endif

#define IDI_LVGL                       101

#include "lvgl/lvgl.h"
#include "lvgl/examples/lv_examples.h"
#include "lv_demos/lv_demo.h"
#include "lv_drivers/win32drv/win32drv.h"

#if _MSC_VER >= 1200
// Restore compilation warnings.
#pragma warning(pop)
#endif


int main()
{
    lv_init();

    if (!lv_win32_init(
        GetModuleHandleW(NULL),
        SW_SHOW,
        800,
        480,
        LoadIconW(GetModuleHandleW(NULL), MAKEINTRESOURCE(IDI_LVGL))))
    {
        return -1;
    }

    lv_win32_add_all_input_devices_to_group(NULL);

    lv_demo_widgets();

    while (!lv_win32_quit_signal)
    {
        lv_task_handler();
        Sleep(1);
    }
    return 0;
}

在C++预处理器中增加如下内容

_CRT_SECURE_NO_WARNINGS
UNICODE

在C++附加包含目录中新增加入以下路径

在lv_drv_conf.h中打开以下宏

#ifndef USE_WIN32DRV
#  define USE_WIN32DRV       1
#endif

将lvgl,lv_drivers,lv_demos包含到工程中

将lv_demo_conf.h中内容修改成如下

/**
 * @file lv_demo_conf.h
 * Configuration file for v8.1.0-dev
 *
 */
/*
 * COPY THIS FILE AS lv_demo_conf.h
 */

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