+# lvgl_st7789_use 组件说明
+
+`lvgl_st7789_use` 是项目中的 LCD 显示组件，基于 `esp_lcd + esp_lvgl_port`，用于快速驱动 ST7789 SPI 屏并显示 LVGL 界面。
+
+---
+
+## 功能概览
+
+- 初始化 SPI LCD（含背光、面板、显示偏移）
+- 初始化 LVGL 端口并注册显示设备
+- 默认创建一个居中标签用于快速验证显示链路
+- 提供运行时更新中心文本接口
+- 支持可配置方向、镜像与偏移
+- 支持可选三色测试图（调试用）
+
+---
+
+## 对外 API
+
+头文件：`include/lvgl_st7789_use.h`
+
+- `esp_err_t start_lvgl_demo(void);`
+  - 完成 LCD + LVGL 初始化并创建默认界面
+
+- `esp_err_t lvgl_st7789_set_center_text(const char *text);`
+  - 运行时更新中心标签文字（线程安全，内部已加锁）
+
+---
+
+## 关键配置项（可直接改宏）
+
+在 `include/lvgl_st7789_use.h` 中：
+
+### 1) 屏幕与 SPI
+
+- `EXAMPLE_LCD_H_RES` / `EXAMPLE_LCD_V_RES`
+- `EXAMPLE_LCD_PIXEL_CLK_HZ`
+- `EXAMPLE_LCD_SPI_NUM`
+- `EXAMPLE_LCD_CMD_BITS` / `EXAMPLE_LCD_PARAM_BITS`
+
+建议：ST7789 默认可先用 `20MHz`，如出现花屏或不稳定再降到 `10MHz` 复测。
+
+### 2) 颜色校准（重点）
+
+- `EXAMPLE_LCD_COLOR_ORDER_BGR`
+- `EXAMPLE_LCD_INVERT_COLOR`
+- `EXAMPLE_LCD_SWAP_BYTES`
+
+说明：
+- 出现“黑色发灰、红绿蓝偏紫/互串”时，优先调整这三项。
+- 建议从 `RGB + 不反色 + 不交换字节` 起步，再逐项切换。
+
+### 3) 方向与偏移（重点）
+
+- `EXAMPLE_LCD_GAP_X`
+- `EXAMPLE_LCD_GAP_Y`
+- `EXAMPLE_LCD_ROT_SWAP_XY`
+- `EXAMPLE_LCD_ROT_MIRROR_X`
+- `EXAMPLE_LCD_ROT_MIRROR_Y`
+
+说明：
+- 若出现“文字偏移/边缘花屏/方向反了”，优先微调上述宏，不要同时在多层重复旋转。
+
+### 4) 调试项
+
+- `EXAMPLE_LCD_ENABLE_COLOR_TEST`
+  - `1`：上电先画 RGB 三色测试图（便于确认硬件链路）
+  - `0`：跳过测试，直接进入 LVGL
+
+---
+
+## 在主程序中调用
+
+```c
+#include "esp_check.h"
+#include "lvgl_st7789_use.h"
+
+void app_main(void)
+{
+    ESP_ERROR_CHECK(start_lvgl_demo());
+  ESP_ERROR_CHECK(lvgl_st7789_set_center_text("BotanicalBuddy"));
+}
+```
+
+---
+
+## 常见问题
+
+### 1) 背光亮但没有内容
+
+优先排查：
+- 面板型号与驱动是否匹配（当前应为 ST7789）
+- SPI 模式、时钟是否过高
+- 方向/偏移参数是否正确
+
+### 2) 文字方向反了或显示偏移
+
+优先调整：
+- `EXAMPLE_LCD_ROT_*`
+- `EXAMPLE_LCD_GAP_X / EXAMPLE_LCD_GAP_Y`
+
+### 3) 想快速确认硬件链路是否通
+
+把 `EXAMPLE_LCD_ENABLE_COLOR_TEST` 设为 `1`，观察是否能显示三色图。
+
+---
+
+## 依赖
+
+由组件 `CMakeLists.txt` 声明：
+
+- `driver`
+- `esp_lcd`
+- `esp_lvgl_port`
