阶段1: 将 dzbj 项目的 LVGL 8.3.11 LCD 显示集成到 AI小智 主项目， 开机显示 ScreenHome 界面，同时优化配网模式下的内存使用， 确保 WiFi+BLE+LVGL 三者共存运行。 ## 新增功能 ### dzbj 显示模块集成 - 新增 main/dzbj/ 目录，移植 LCD 驱动(ST77916 QSPI)、触摸驱动(CST816S)、 LVGL 初始化和 SquareLine Studio UI 界面 - I2C 总线共享：dzbj 触摸控制器复用主项目的 I2C_NUM_1 总线 - GPIO 冲突解决：LED(GPIO21)、Touch1(GPIO1)、Touch4(GPIO7) 改为 NC， 电池 ADC 从 GPIO6 改为 GPIO3 - 添加 LVGL、esp_lcd_st77916、esp_lcd_touch_cst816s 等组件依赖 - managed_components 纳入版本管理 ### 配网模式轻量化启动 - BoxAudioCodec: 新增 output_only 模式，仅创建 I2S TX 通道（省 ~13KB DMA） 跳过 ES7210 ADC 初始化（省 ~2-4KB） - AudioCodec: 新增 StartOutputOnly() 方法，仅启用扬声器输出 - Application: 配网模式跳过 Opus 编码器、输入重采样器、协议初始化、 天气位置检测等网络业务 - 板级构造函数: 配网模式跳过电池检测、IMU传感器、PowerSaveTimer ### WifiBoard 配网流程修复 - NeedsProvisioning() 静态方法: 读取 NVS force_ap 和 SSID 列表， 用于提前判断配网模式 - force_ap 竞态修复: 构造函数不再清零 force_ap，改在 StartNetwork() 清零， 确保 NeedsProvisioning() 能正确读到 force_ap=1 - Application 缓存 provisioning_mode_ 成员变量，避免重复读 NVS ### BLE 配网重启修复 - 配网成功后用 esp_timer 延迟重启替代 xTaskCreate， 避免内存紧张时任务创建失败导致设备不重启 - 注释掉 WiFi 连接成功后的 MAC 地址发送步骤 ### sdkconfig 内存优化 - BT_ALLOCATION_FROM_SPIRAM_FIRST=y (BLE 动态分配优先 PSRAM) - SPIRAM_MALLOC_RESERVE_INTERNAL=32768 - NVS_ALLOCATE_CACHE_IN_SPIRAM=y - WiFi 静态缓冲区数量优化 (RX=10, TX=8) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Demos for LVGL
Add the examples to your projects
-
demos can be found in the 'demos' folder once you clone the lvgl.
-
In the lv_conf.h or equivalent places, you can find demo related macros, change its value to enable or disable specified demos:
...
/*===================
* DEMO USAGE
====================*/
/*Show some widget. It might be required to increase `LV_MEM_SIZE` */
#define LV_USE_DEMO_WIDGETS 0
#if LV_USE_DEMO_WIDGETS
#define LV_DEMO_WIDGETS_SLIDESHOW 0
#endif
/*Demonstrate the usage of encoder and keyboard*/
#define LV_USE_DEMO_KEYPAD_AND_ENCODER 0
/*Benchmark your system*/
#define LV_USE_DEMO_BENCHMARK 0
/*Stress test for LVGL*/
#define LV_USE_DEMO_STRESS 0
/*Music player demo*/
#define LV_USE_DEMO_MUSIC 0
#if LV_USE_DEMO_MUSIC
# define LV_DEMO_MUSIC_SQUARE 0
# define LV_DEMO_MUSIC_LANDSCAPE 0
# define LV_DEMO_MUSIC_ROUND 0
# define LV_DEMO_MUSIC_LARGE 0
# define LV_DEMO_MUSIC_AUTO_PLAY 0
#endif
...
- If your development environment or toolchain does not add source files inside 'lvgl' folder automatically, ensure the
demosfolder is included for compilation. - Include "demos/lv_demos.h" in your application source file, for example:
//! main.c
#include "lvgl.h"
#include "demos/lv_demos.h"
...
Demos
Widgets
Shows how the widgets look like out of the box using the built-in material theme.
See in widgets folder.
For running this demo properly, please make sure LV_MEM_SIZE is at least 38KB (and 48KB is recommended):
#define LV_MEME_SIZE (38ul * 1024ul)
Music player
The music player demo shows what kind of modern, smartphone-like user interfaces can be created on LVGL. It works the best with display with 480x272 or 272x480 resolution.
See in music folder.
Keypad and encoder
LVGL allows you to control the widgets with a keypad and/or encoder without a touchpad. This demo shows how to handle buttons, drop-down lists, rollers, sliders, switches, and text inputs without touchpad. Learn more about the touchpad-less usage of LVGL here.
See in keypad_encoder folder.
Benchmark
A demo to measure the performance of LVGL or to compare different settings.
See in benchmark folder.
Stress
A stress test for LVGL. It contains a lot of object creation, deletion, animations, style usage, and so on. It can be used if there is any memory corruption during heavy usage or any memory leaks.
See in stress folder.
