-## Highlights
- Modern, material-inspired desktop shell built on the in-repo `modern-qt` library.
- Modular component system (`NavComponent`, `ViewComponent`) for quick UI experiments.
- Real-time tactile matrix visualisation via the `HeatMapPlot` wrapper around QCustomPlot.
- Codec infrastructure (`components/ffmsep`) ready for custom tactile packet decoding.
- Serial transport module scaffolded for COM port discovery and streaming.
+## 项目亮点
+- 基于仓库内置的 `modern-qt` 库构建现代化、贴近 Material 风格的桌面壳层。
+- 左侧导航栏搭配卡片式主界面，集中承载串口控制面板与双热力图视图。
+- 实时触觉数据流水线：`ffmsep::CPStreamCore` 负责串口 I/O、编解码调度与帧缓存。
+- 内置触觉编解码模块（`ffmsep::tactile`）自动解析载荷、推断矩阵尺寸并输出压力量表。
+- 两套 `HeatMapPlot` 组件通过响应式数据源实时刷新，并与主题色梯度联动。

-## Architecture At A Glance
- **Entry point**: `main.cc` composes the themed window, navigation rail, and card-based layout.
- **Components**: `components/` hosts UI widgets, charts, and the tactile decoder pipeline.
- **Modern Qt toolkit**: `modern-qt/` provides declarative wrappers, theming, and Material icon helpers.
- **Data layer**: `components/ffmsep` implements codec registration, packet decoding, and tactile frame processing.
- **Visualisation**: `components/charts/heatmap.*` exposes a themable heatmap control for sensor grids.
+## 当前进展
+- UI 内可完成串口的搜索、连接与断开，同时支持周期性从站轮询指令。
+- 编解码注册流程已接入触觉解码器，控制台输出原始帧内容与矩阵提示，便于调试。
+- 双热力图面板会根据解码结果动态调整矩阵尺寸，停止串流时自动回落至默认状态。
+- 同时提供 `cpstream_demo` CLI，用于在无界面环境校验串流核心逻辑。

-## Getting Started
+## 架构速览
+- **入口**：`main.cc` 负责加载主题、导航栏、遮罩动画以及传感器面板。
+- **组件层**：`components/` 收纳导航/视图界面、图表组件以及触觉串流管线。
+- **Modern Qt 工具集**：`modern-qt/` 提供声明式封装、主题系统与 Material 图标工具。
+- **串流与编解码**：`components/ffmsep` 打包编解码注册、`CPStreamCore` 与触觉帧解析工具。
+- **可视化**：`components/charts/heatmap.*` 提供可主题化的热力图控件，支持梯度和矩阵重设。
+- **示例**：`examples/` 下的 `cpstream_demo.cc` 可单独运行验证串流核心。

-### Prerequisites
+## 快速开始
+
+### 环境要求
 - CMake 3.20+
- A C++23-capable compiler (MSVC 19.3x, Clang 16+, or GCC 13+)
- Qt 6 (Widgets, Network, PrintSupport modules)
+- 支持 C++23 的编译器（MSVC 19.3x、Clang 16+ 或 GCC 13+）
+- Qt 6（至少包含 Widgets、Network、PrintSupport 模块）
 - Eigen3
- `spdlog` (fetched via package manager or provided to CMake)
+- `spdlog`（可通过包管理器安装或手动提供给 CMake）
+- [`serial`](https://github.com/wjwwood/serial)（跨平台串口库，可包管理器安装或自行构建）

-Ensure `Qt6_DIR` (or `CMAKE_PREFIX_PATH`) points to the Qt install so CMake can locate the required modules.
+确保 `Qt6_DIR` 或 `CMAKE_PREFIX_PATH` 指向 Qt 安装路径，以便 CMake 正确找到依赖模块。

-On Linux/macOS adjust the Qt path and executable name accordingly.
+在 Linux/macOS 上使用对应的 Qt 安装路径与可执行文件名。

-## Project Layout
+### 运行传感器界面
+- 通过 USB 接入触觉设备，确认系统识别到的串口号。
+- 启动 `touchsensor.exe`（或平台对应的可执行文件）。
+- 在串口下拉列表中选择端口，可按需刷新；若需更换波特率请同步调整。
+- 点击链接图标开始串流，双热力图将实时更新，控制台亦会打印原始载荷。
+- 再次点击链接图标即可断开连接，界面会回落到默认示例数据。
+
+当 `BUILD_EXAMPLE` 选项开启时会同步构建 `cpstream_demo`，可在终端中运行验证串流与编解码流程。

-## Roadmap (WIP)
- Flesh out tactile codec implementations and connect them to live serial streams.
- Replace placeholder random data with decoded sensor frames.
- Expand navigation targets beyond the current demo cards.
- Capture screenshots or recordings for documentation.
- Polish theming, animation masks, and landing experience.
+## 路线图（进行中）
+- **已完成** 串口串流管线（轮询、编解码回调、热力图数据绑定）已连通。
+- **已完成** HeatMapPlot 支持矩阵提示与梯度调节，能随解码结果刷新。
+- **规划中** 引入内置诊断/历史面板，替换当前的标准输出日志。
+- **规划中** 保存串口偏好、提供手动矩阵覆写，并补充文档素材。
+- **规划中** 扩展导航目标，完善非传感器场景。
