下载资料后解压文件及安装VS2022 ，选择通用windows平台开发及Visual Studio进行安装，安装步骤略

打开VS2022，点击创建新项目

选择Windows Console Application (C++/WinRT)，点击下一步

输入名程lvgl_v9_sim,选择目录，勾选将解决方案和项目放在同一目录中，点击创建，再点击确定

在工程目录中新建一个文件夹并命名为lvgl_folder

将下载的lv_drivers,lvgl两个文件夹复制到lvgl_folder文件中

将lv_drivers中的lv_drv_conf_template.h和lvgl中的lv_conf_template.h的文件复制到lvgl_folder目录下，并分别命名为lv_drv_conf.h和lv_conf.h

在工程中分别创建lvgl,lvgl_drivers两个筛选器

将lvgl_folder文件夹中的文件分别加入到工程

点击显示所有文件，包含添加的文件在项目中

将lv_drv_conf.h文件中的条件编译总开关打开

• #if 0改成#if 1

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

• 将USE_WIN32DRV宏设为1

/*----------------------------
 *  Native Windows (win32drv)
 *---------------------------*/
#ifndef USE_WIN32DRV
#  define USE_WIN32DRV       1
#endif

#if USE_WIN32DRV
/* Scale window by this factor (useful when simulating small screens) */
#  define WIN32DRV_MONITOR_ZOOM        1
#endif

将lv_conf.h中的文件配置如下

• 编译总开关由#if 0改成#if 1

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

• LV_MEM_SIZE宏定义为(1024U * 1024U)

 /*Size of the memory available for `lv_mem_alloc()` in bytes (>= 2kB)*/
    #define LV_MEM_SIZE (1024U * 1024U)          /*[bytes]*/

• LV_TICK_CUSTOM宏设为1，定义windos.h文件，定义时间函数GetTickCount()

/*Use a custom tick source that tells the elapsed time in milliseconds.
 *It removes the need to manually update the tick with `lv_tick_inc()`)*/
#define LV_TICK_CUSTOM 1
#if LV_TICK_CUSTOM
    #define LV_TICK_CUSTOM_INCLUDE <Windows.h>          /*Header for the system time function*/
    #define LV_TICK_CUSTOM_SYS_TIME_EXPR (GetTickCount())    /*Expression evaluating to current system time in ms*/
#endif   /*LV_TICK_CUSTOM*/

• 将宏LV_USE_LOG设为1

/*Enable the log module*/
#define LV_USE_LOG 1

• 将LV_USE_PERF_MONITOR和LV_USE_MEM_MONITOR设为1

/*1: Show CPU usage and FPS count*/
#define LV_USE_PERF_MONITOR 1
#if LV_USE_PERF_MONITOR
    #define LV_USE_PERF_MONITOR_POS LV_ALIGN_BOTTOM_RIGHT
#endif

/*1: Show the used memory and the memory fragmentation
 * Requires LV_MEM_CUSTOM = 0*/
#define LV_USE_MEM_MONITOR 1
#if LV_USE_MEM_MONITOR
    #define LV_USE_MEM_MONITOR_POS LV_ALIGN_BOTTOM_LEFT
#endif

• 将LV_FONT_MONTSERRAT_12和LV_FONT_MONTSERRAT_16设为1

/*Montserrat fonts with ASCII range and some symbols using bpp = 4
 *https://fonts.google.com/specimen/Montserrat*/
#define LV_FONT_MONTSERRAT_8  0
#define LV_FONT_MONTSERRAT_10 0
#define LV_FONT_MONTSERRAT_12 1
#define LV_FONT_MONTSERRAT_14 1
#define LV_FONT_MONTSERRAT_16 1
#define LV_FONT_MONTSERRAT_18 0
#define LV_FONT_MONTSERRAT_20 0
#define LV_FONT_MONTSERRAT_22 0
#define LV_FONT_MONTSERRAT_24 0
#define LV_FONT_MONTSERRAT_26 0
#define LV_FONT_MONTSERRAT_28 0
#define LV_FONT_MONTSERRAT_30 0
#define LV_FONT_MONTSERRAT_32 0
#define LV_FONT_MONTSERRAT_34 0
#define LV_FONT_MONTSERRAT_36 0
#define LV_FONT_MONTSERRAT_38 0
#define LV_FONT_MONTSERRAT_40 0
#define LV_FONT_MONTSERRAT_42 0
#define LV_FONT_MONTSERRAT_44 0
#define LV_FONT_MONTSERRAT_46 0
#define LV_FONT_MONTSERRAT_48 0

• 在lv_config.h中将demo相关例程宏设为1

/*==================
* EXAMPLES
*==================*/

/*Enable the examples to be built with the library*/
#define LV_BUILD_EXAMPLES 1

/*===================
 * DEMO USAGE
 ====================*/

/*Show some widget. It might be required to increase `LV_MEM_SIZE` */
#define LV_USE_DEMO_WIDGETS 1
#if LV_USE_DEMO_WIDGETS
    #define LV_DEMO_WIDGETS_SLIDESHOW 1
#endif

/*Demonstrate the usage of encoder and keyboard*/
#define LV_USE_DEMO_KEYPAD_AND_ENCODER 1

/*Benchmark your system*/
#define LV_USE_DEMO_BENCHMARK 1
#if LV_USE_DEMO_BENCHMARK
    /*Use RGB565A8 images with 16 bit color depth instead of ARGB8565*/
    #define LV_DEMO_BENCHMARK_RGB565A8 0

点击项目菜单，点击属性

点击C/C++,选择常规，在附加包含目录中加入lvgl_folder,点击应用

在main.cpp中换成以下内容，并将main.cpp文件重命名为main.c

#include "lvgl/lvgl.h"
#include "lvgl/demos/music/lv_demo_music.h"
#include "lv_drivers/win32drv/win32drv.h"

#define IDI_LVGL                       101

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_music();
  

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

将C/C++中预编译头，选择不使用预编译头

在C++预处理器中新增加如下内容

在链接器，输入，附加依赖项加入以下内容

kernel32.lib
