# AGENTS.md — DLPilot 工程档案(供 AI/Agent 使用)
> **本文档面向 AI/Agent**,是人类文档 [README.md](README.md) 的姊妹篇,两者不重叠:
> README 回答"这是什么、怎么用";本文回答"代码怎么组织、怎么构建发布、改动时哪些约束不能破坏"。

## 1. 项目定位
仓库 `LT8619C_Debug_Tools` 是 LT8619C(HDMI→RGB888)→ DLPC3421 投影转接板的**调试上位机工具集**,
上游主仓库(固件)为 `hulk/LT8619C_DLPC3421_HDMI`(同 Gitea 实例 `gitea.hulk.wang`),
本仓库本机路径 `E:\Hulk-Coding\LT8619C_DLPC3421_HDMI`。
DLPilot 工作在两端:HDMI **源端**(PC 显卡侧,EDID/分辨率/图案)与**光机控制端**
(RS485 → 板载 GD32E230 网关 → DLPC3421)。寄存器语义判读基线(0x606E 位交换 /
0x606D 整组顺序)与光机协议规程都在上游仓库 `doc/architecture/` 与 `protocols.md`,不在本仓库。
## 2. 目录契约(重要)
```
DLPilot/
├── src/ 源代码区 —— 只有这里可以手改(logos/ 改图标源后重跑 make_ico.py)
├── assets/ 生成资产区 —— gen_*.py 的产物(PNG 图案),可随时再生成,改动需提交
├── release/ 产物区 —— 机器生成,禁止手改:DLPilot.exe、pattern_slots.json、
│ bw/solid 图案(package_release.py 从 assets/ 平铺复制来,均入库)、
│ *.zip(gitignore,只上传 Release)。release/ 本身=完整可直接运行的
│ 发布文件夹(exe+附属平铺),内容与 zip 一致
├── README.md 人类文档
└── AGENTS.md 本文
```
划分原则:**"人写的"在 src/,"生成的"按去向分 assets/(随包分发)与 release/(直接交付)**。
新文件必须落对区域;不要在 src/ 外新建源码,不要手改 assets/ 下的 PNG(改生成脚本再跑)。
### 文件角色速查
| 文件 | 角色 |
|---|---|
| `src/hdmi_gui.py` | 入口: argparse 命令行分发(--dump/--edid-fields/--test-pattern/--dlpc-cmd/--seconds), GUI 委托 app_gui |
| `src/app_gui.py` | CustomTkinter 主界面: 双栏仪表盘(左 HDMI 源端五卡/右 光机四卡), 光强/定时快捷滑条 |
| `src/display_win.py` | Win32 显示器枚举/分辨率切换/智能拓扑(纯 ctypes) |
| `src/edid_parse.py` | EDID 1.4/CEA-861 解析(纯标准库, 上游 lt8619c_edid.c 以此为参考解码器) |
| `src/patterns.py` | 测试图案全屏投屏窗口(tkinter, ESC 退出, 测试卡区域 1:1 居中) |
| `src/config.py` | 运行目录定位(BASE_DIR)与 pattern_slots.json 读写(slots/area/serial 三键) |
| `src/dlpc_rs485.py` | 光机 RS485 协议模块: 帧构造/增量解析/译码表/预设命令/串口线程(DLPC485) |
| `src/selftest_rs485.py` | 光机协议自检(对照上游实测帧向量, 无硬件回归, 改协议代码后必跑) |
| `src/build_exe.py` | PyInstaller 打包 → `release/DLPilot.exe`(onefile/noconsole, 内嵌图标+pyserial+customtkinter) |
| `src/package_release.py` | 复制图案到 release/(平铺) → `release/DLPilot-v<ver>-win64.zip`(校验栏位引用完整性; release/ 与 zip 内容一致) |
| `src/publish_gitea.py` | 建/复用 Gitea Release 并上传 zip(tag 默认取 zip 文件名) |
| `src/hdmi_source.ps1/.bat` | 独立 PowerShell 命令行工具(自包含,与 GUI 无代码共享) |
| `src/gen_bw_patterns.py` | 生成 `assets/bw_*.png` ×5(640x360 黑白,需 Pillow) |
| `src/gen_solid_colors.py` | 生成 `assets/solid_*.png` ×10(800x600 纯色,需 Pillow) |
| `src/la_wave_analyzer*.py` | 逻辑分析仪 CSV 波形判读(2/3 通道,40MHz 像素时钟假设) |
| `src/logos/make_ico.py` | svg/png → ico(写在其自身目录) |
| `release/pattern_slots.json` | 预置栏位:西门子星/波带片/综合测试卡,area=640x360;`serial` 键记忆光机串口 |
| `UI参考布局.svg/.png` | 界面布局设计稿(app_gui.py 双栏布局的规格来源, 随分支入库) |
## 3. 代码不变量(改 hdmi_gui.py 必须维持)
1. **依赖分层**:CLI/显示/EDID/协议/配置模块(display_win/edid_parse/patterns/config/
dlpc_rs485)纯标准库;customtkinter 是 GUI(app_gui)的**硬依赖**(装了才能开界面,
CLI 不受影响)。可选依赖仍走"try-import + HAS_* 标志 + 缺失降级"模式:Pillow、
pyserial——缺失时对应功能禁用/提示安装,其余功能必须照常工作。
2. **模块边界**:hdmi_gui.py 只是入口, 不放实现; GUI 不直接碰 ctypes/winreg
(显示器走 display_win, EDID 走 edid_parse); pyserial 只准在 dlpc_rs485.py 里 import
(hdmi_gui/app_gui 经 `dlpc_rs485.HAS_SERIAL` 与 `DLPC485` 类间接使用)。
3. **BASE_DIR 语义**(定义在 config.py):frozen(PyInstaller onefile)时
`BASE_DIR=exe 所在目录`(`sys.executable`),源码运行时 `=config.py 所在目录`
(即 src/)。所有用户数据(pattern_slots.json、自定义图片)都写/读自 BASE_DIR
**平铺**存放,不建子目录。
4. **自定义栏位 `file` 字段是裸文件名**:加载时 `os.path.join(BASE_DIR, file)` 解析,
因此 pattern_slots.json 引用的图片必须与 exe 同目录 —— package_release.py 正是按此平铺打包。
5. **exe 自包含**:图标经 `--add-data` 内嵌(运行时从 `_MEIPASS` 读);内置五种图案
(红/绿/蓝/棋盘格/网格线)由程序绘制,运行时**不依赖** assets/;solid/bw PNG 只服务自定义栏位。
6. **DPI 感知**:进程启动即 `SetProcessDpiAwareness(2)`,图案窗口按物理像素定位,勿移除。
7. **智能显示拓扑(勿改回无条件扩展)**:启动时枚举"接入但不在桌面"的显示器,仅当其
EDID 厂商字节为转接板签名 `61 93`(压缩码 "XLS",上游 lt8619c_edid.c)时才
`SetDisplayConfig(SDC_TOPOLOGY_EXTEND|SDC_APPLY)` 拉回桌面,静默容错。动机:板卡
热插拔后 Windows 可能停留在"仅电脑屏幕"导致枚举不到板卡。用户主动选择的拓扑
(家里的"仅第二屏幕"等,未激活的是笔记本内屏,厂商非 XLS)一律不动。
8. **分辨率切换是临时的**:走 `CHANGEDISPLAYSETTINGS`(不写注册表),"恢复"用会话开始时快照。
9. **EDID 来源是注册表**(`HKLM\SYSTEM\CurrentControlSet\Enum\DISPLAY\...\Device Parameters\EDID`),
不是 WMI/DDC;exe 的 noconsole 版无 stdout,`--dump/--edid-fields` 只在源码/控制台版可用。
10. **光机串口线程回调不直接碰 GUI**:DLPC485 的 on_event/on_status 在后台线程触发,
必须经 `queue.Queue` + `root.after(80, …)` 轮询投递回主线程(现行 `_poll_dlpc` 模式,
与 I2C-Inject 的 Injector 同源);退出路径(关窗与 `--seconds` 自动关)都会走到
`App.destroy()`,在那里 `dlpc.close()` 收线程。
11. **pattern_slots.json 格式**:`{'area', 'slots', 'serial'}` 三键共存;load 兼容旧版
纯数组(无 area)与无 serial 键两种历史格式,save 永远写全三键。`serial` 子键为
`{port, baud, bytesize(8/7/6/5), parity(N/E/O), stopbits(1/2)}`,旧配置缺子键按
默认 8-N-1 补齐。
12. **GUI = app_gui.py 双栏仪表盘**(规格:`DLPilot/UI参考布局.svg`):左列 HDMI 源端
五卡(显示器/模式/EDID 信息/测试图案/hex),右列光机四卡(串口/数据/命令/滑条),
顶栏 Dark/Light/System 切换(ttk.Treeview 颜色随动)。打包必须 `--collect-all
customtkinter`(build_exe.py 已内置,勿删)——CTk 主题/字体数据缺失会让 exe 启动即崩。
## 4. 领域语义(测试值都有含义,勿"顺手改")
- 纯色值 55/AA/FF:55(01010101) 与 AA(10101010) 互为字节镜像对(检出位序颠倒/位交换),
FF(11111111) 全高基准;R/G/B 三行对应 RGB888 三字节组(R=D[23:16]/G=D[15:8]/B=D[7:0])。
- 800x600@60:LT8619C **demo 板** shadow EDID 首选时序(solid 系列分辨率与之一致)。
- 640x360:测试卡区域默认值(16:9 半分辨率,点对点检查用);full=铺满所选屏。
**同时是转接板光机 DLPC3421 的 nHD 面板原生分辨率**(该板 shadow EDID 只声明 640x360@60),
投 640x360 图案 + RS485 开光机 = 整链路 1:1 验证。
- bw 系列图案各自目的见 `src/gen_bw_patterns.py` 顶部清单注释。
- 光机 RS485 命令集(M730/M731/M732/M201/M202/M737/M999/M888/M7/M8/M1)语义、
帧格式 `D5 01 LEN <ASCII> CRC`(累加和校验)、错误码与**就绪门禁**
(DLPC 未就绪时 M730/M731/M732 被拒回 0xFF)以上游 `protocols.md` 为唯一权威,
本仓不维护协议文档副本;注意 **M7S0 是"开启"TEC 自动控温**(方向反直觉)、
M737 在定时投光中延迟应答(CLI 等待上限 35s)。
## 5. 构建 / 发布流水线(全部在 src/ 下执行)
```powershell
python gen_bw_patterns.py ; python gen_solid_colors.py # 仅当改了图案生成逻辑
python build_exe.py # → ../release/DLPilot.exe(缺 PyInstaller 会自动 pip install)
python build_exe.py --debug # 附加带控制台的 DLPilot-console.exe(调试 --dump 用)
python package_release.py <版本> # → ../release/DLPilot-v<版本>-win64.zip
python publish_gitea.py DLPilot-v<版本>-win64.zip --replace --insecure # 上传(需 GITEA_TOKEN)
```
发布约定:
- tag/release 命名 `DLPilot-vX.Y.Z`,zip 命名 `DLPilot-vX.Y.Z-win64.zip`(publish_gitea.py
依赖此命名从文件名推 tag);
- **exe、pattern_slots.json 与 release/ 下平铺的图案 png 改动跟随源码/资产生成提交入库;
zip 永不入库**(.gitignore 已挡);
- publish_gitea.py 幂等:release 已存在则复用,同名资产默认跳过,`--replace` 删旧重传;
- token 读环境变量 `GITEA_TOKEN`:本机已用 setx 持久化为用户级变量(新开的会话/终端自动
继承,值不入库;在 setx 之前启动的进程读不到,需重开终端),急用时也可临时传 `--token`;
- Gitea 实例 `gitea.hulk.wang`,API 走 https(443),git 走 ssh(1234)——从 origin 远程自动解析;
python urllib 连该实例会在部分请求上报 `SSL: UNEXPECTED_EOF`,**实际发布需加 `--insecure`**;
- 本实例 Gitea 的 API 兼容性怪癖:`GET /releases/tags/{tag}` 返回的 `assets` 是纯数组,
而 `GET /releases/{id}` 是 `{items:[...]}` —— publish_gitea.py 已按两种形状兼容,勿"简化"回去。
## 6. 已知坑(历史踩过,勿重蹈)
- onefile 运行时 `__file__` 指向临时解压目录 `_MEIPASS`,定位 exe 必须用 `sys.executable`(§3.3);
- 重新打包前旧 exe 可能被残留进程占用 → build_exe.py 会 taskkill 同名进程,手改打包脚本时保留;
- 打包后本机图标缓存不刷新:`ie4uinit -show`,不是产物问题;
- 改图标流程:改 svg → `make_ico.py` 生成 ico → 重新打包(ico 同时是文件图标与运行时窗口图标);
- GUI 与 hdmi_source.ps1 各自独立实现显示器枚举,行为可能微差(GUI 与 `-List` 序号一致,
但与"设置"面板序号无保证);多屏操作前先确认序号;
- `pattern_slots.json` 兼容两种历史格式,写出只写新格式(详见 §3.11);
- CustomTkinter 6.x:`CTkComboBox` 不支持 `textvariable`(用 `.set()/.get()`);`CTkTextbox`
的 `tag_config` 在部分版本不可用,app_gui 已 try/except 兜底为单色;同一容器内
grid/pack 不可混用(卡片用 grid 挂进列,卡片内部一律 pack——`_card` 返回 (卡片, 内容));
## 7. 验证清单(改完代码后)
1. `python -m py_compile src/*.py` —— 全模块可编译;
2. `python selftest_rs485.py` —— 光机协议回归(改 dlpc_rs485.py 后必跑,向量来自上游 protocols.md);
3. `python hdmi_gui.py --seconds 5` —— GUI 冒烟(自动开关);
4. `python hdmi_gui.py --test-pattern Checker --area 800x600 --seconds 3` —— 投图链路;
5. `python hdmi_gui.py --dump` —— EDID 解算不抛异常;
6. `python hdmi_gui.py --dlpc-cmd M999`(不带 --port)—— 应明确报错而非崩溃(无硬件时的优雅降级);
7. `python build_exe.py` → 双击 release/DLPilot.exe 确认图标/双栏布局/投图/光机区渲染;
8. `python package_release.py <版本>` —— 不报"引用图片缺失"即栏位完整性 OK。

## 1. 功能总览
| 功能 | 说明 |
|---|---|
| EDID 查看 | 枚举各显示输出口,从注册表读取 EDID 原始数据,按 EDID 1.4/CEA-861 解算:厂商/型号/尺寸/Gamma/输入类型/支持模式(DTD/已建立/标准/CEA-VIC)/首选时序完整参数/校验和 |
| EDID 逐字节解析 | "EDID 原始数据"框右上"逐字节解析"按钮:按偏移逐字段展开基础块与 CTA-861 扩展块,每字段附原始字节 hex;命令行等价 `--edid-fields` |
| 分辨率切换 | "分辨率"下拉列出显卡按该屏 EDID 提供的全部模式;**应用**=临时切换(不写注册表,重启/恢复即还原),**恢复**=回到本次会话切改前的模式 |
| 测试图案投屏 | 全屏投到所选显示器,测试卡区域可选 `640x360 / 800x600 / full 铺满`;内置 纯红/纯绿/纯蓝/黑白棋盘格/网格线 + R/G/B 三行 55/AA/FF 纯色值按钮 + 3 个自定义图片栏位 |
| 界面 | CustomTkinter 深色双栏仪表盘(左列 HDMI 源端 / 右列 光机控制),顶栏可切换 Dark/Light/System |
| 光机控制 | RS485 → 板载 GD32E230 网关 → DLPC3421:开关光机(可定时)、设光强、查电流/温度/版本、TEC 控制、软件重启;光强/定时提供快捷滑条;收发日志带协议译码(见 §5) |
| 智能显示拓扑 | 仅当检测到转接板(EDID 厂商 "XLS")接入但未进入桌面(Windows 卡在"仅电脑屏幕")时才强制扩展把它拉回;你主动选的"仅第二屏幕"等拓扑不会被改动 |
| 命令行模式 | 全部功能可脚本化调用,供自动化测试(见 §6、§7) |
| 波形分析脚本 | 逻辑分析仪 CSV 波形按占空比签名分段,输出行结构/占空比/消隐明细(见 §7.3) |
## 2. 下载与安装
1. 打开 [Releases 页面](https://gitea.hulk.wang/hulk/LT8619C_Debug_Tools/releases),取最新的
`DLPilot-vX.Y.Z-win64.zip`;
2. 解压到**任意可写目录**(自定义图片与栏位配置会写到 exe 旁边);
3. 双击 `DLPilot.exe`。首次启动比脚本慢一两秒(onefile 解压),属正常现象。
包内包含:
```
DLPilot/
├── DLPilot.exe 主程序(单文件自包含, 光机控制的 pyserial 已内置)
├── pattern_slots.json 预置自定义栏位 + 串口记忆
├── bw_*.png ×5 640x360 黑白测试图
├── solid_*.png ×10 800x600 纯色测试图
└── README.md 本说明
```
## 3. GUI 使用
主窗口为双栏仪表盘(布局设计稿:`UI参考布局.svg`),默认跟随系统深/浅色外观
(顶栏可切换 Dark/Light/System),顶栏右侧"关于"按钮内含软件信息:
```
左列(HDMI 源端) 右列(光机控制 RS485)
┌ 显示器选择区域 [刷新] ┐ ┌ 串口选择 + 波特率/8-N-1 参数/连接 ┐
├ 支持的模式: 分辨率[应用][恢复] + 明细 ┐ ├ 串口数据 — 收发日志(译码+hex) ┤
├ EDID 信息(表格) ┘ ├ 光机命令 — 快捷按钮+TEC │
├ 测试图案 / 纯色 / 自定义 / 测试卡区域 │ 预设下拉 / 自定义 / 温度读取 │
├ EDID 原始数据 [逐字节解析] ┘ └ 快捷滑条 — 光强/定时/TEC温度 ┘
```
1. 左上显示器下拉选择目标屏(多屏时注意别选成主屏),"刷新"重新枚举;
2. **切分辨率**:"支持的模式"卡片里选模式 → "应用";测完点"恢复";
3. **投测试图**:"测试图案"卡片先选**测试卡区域**(640x360 / 800x600 / full)→
点图案按钮全屏投放,按 **ESC** 或点击退出;R/G/B 纯色按钮(55/AA/FF,按通道着色)
用于 RGB 位交换类测试;自定义图片点齿轮按钮配置(图片自动复制到 exe 旁),
"校准图案"一排为 3D 光固化测试/校准图预留槽位;
4. **光机控制**:右列选串口与参数(波特率/数据位/校验/停止位,默认 115200 8-N-1)→ 连接 →
快捷按钮/预设下拉/自定义输入(回车即发);"查DMD温度""查LAMP温度"读温度
(应答实时填入按钮旁的显示框);快捷滑条:光强拖动后"下发电流值",
定时毫秒后"开光机(定时)"(0=不限时 M730S0),TEC 凝露点滑条/输入框
(200-350 即 20.0-35.0°C)后"下发温度值";数值框输入后回车自动限幅同步;
5. 测试卡区域、自定义栏位与串口记忆(含参数)自动保存在 exe 旁的 `pattern_slots.json`。
## 4. 典型测试场景
```
1. HDMI 接转接板 → 启动 DLPilot → 刷新 → 选中板卡显示器
2. 板卡 shadow EDID 首选 640x360@60 → 测试卡区域选 640x360(与光机面板原生 1:1)
3. "光机控制"连接串口 → M999 查版本确认链路通 → M730S0 开光机
4. 点 R/G/B 行纯色按钮投图 → 目视/逻辑分析仪核对 RGB888 输出
- 纯红/绿/蓝:验证通道映射(R=D[23:16], G=D[15:8], B=D[7:0])
- 55/AA 对:验证位交换(0x606E)——图像应为 50% 灰阶占空比
5. M731S100 设光强 → M732 查电流读回复核 → M730S1 关光机
```
寄存器语义(0x606E 位交换 / 0x606D 整组顺序)与光机协议的判读基线见上游主仓库
[LT8619C_DLPC3421_HDMI](https://gitea.hulk.wang/hulk/LT8619C_DLPC3421_HDMI) 的 `doc/architecture/`。
## 5. 光机控制(RS485 → GD32 网关 → DLPC3421)
物理链路:PC 经 **USB-RS485 转换器**接板卡 A/B 端子,板上 GD32E230 做 RS485→I2C 网关
控制 DLPC3421(I2C 地址 0x1B)。串口参数 **115200, 8N1**,协议细节以上游固件仓
`protocols.md` 为准:命令帧 `D5 01 LEN <ASCII命令> CRC`、响应帧 `B5 TYPE LEN <payload> CRC`,
CRC 为第 2 字节起累加和取低 8 位。
GUI"光机控制"区:选串口 → 连接 → 点快捷按钮或命令下拉/自定义输入发送;串口下拉显示
"COMx + 设备描述",CH344 等多路适配器每一路描述不同(如 serial-A/B/C/D),据此选口;
多口描述相同时自动附物理位置消歧。日志区实时显示 `→ 命令` / `← 译码结果 (原始 hex)`,
错误自动附释义(如 `err:3(I2C NACK)`)。
| 命令 | 功能 | 响应示例 |
|---|---|---|
| `M730S0` / `M730S1` | 开 / 关光机 | `ok` |
| `M730S0T2000` | 开光机并定时 2000ms 自动关(≤32700) | `ok`(期间 M737 延迟应答) |
| `M731S100` | 设光强 54-800(RGB 同值,写后读回复核) | `ok` / `err:R..G..B..` |

注意:**DLPC3421 启动完成前 M730/M731/M732 被就绪门禁拒绝**(回 0xFF),上电后稍等几秒再发。
命令行等价(源码方式):
```
python hdmi_gui.py --port COM9 --dlpc-cmd M730S0 --dlpc-cmd M999
逐条发送并打印译码响应
```
## 6. 命令行模式(hdmi_gui.py)
exe 版无控制台,`--dump/--edid-fields` 的输出不可见(`--dlpc-cmd` 仍可执行,靠退出码判断),
调试请用源码方式:
```
python hdmi_gui.py --dump 控制台输出 EDID 解算
python hdmi_gui.py --edid-fields 控制台输出 EDID 逐字节字段解析表
python hdmi_gui.py --test-pattern Blue --area 800x600 --seconds 5
出图 5 秒自动退出
python hdmi_gui.py --test-pattern Custom1 投自定义栏位 1
python hdmi_gui.py --port COM9 --dlpc-cmd M730S0 RS485 发光机命令(可多次)
python hdmi_gui.py --seconds 5 GUI 冒烟测试, 5 秒自动关
--test-pattern {Red,Green,Blue,Checker,Grid,Custom1..3}
--area {640x360,800x600,full} --monitor N --seconds S
--port COMx --baud 115200 --dlpc-cmd CMD(可重复; 任一命令失败退出码 1)
```
## 7. 辅助脚本(src/ 下)
### 7.1 hdmi_source.bat / .ps1 — 源端命令行工具
与 GUI 互补,适合脚本串联:
```
tools\hdmi_source.bat -List 枚举显示器与支持分辨率(验证 EDID)
tools\hdmi_source.bat -Monitor 1 -Mode 800x600 切模式
tools\hdmi_source.bat -Mode 800x600 -Pattern -Restore
切模式→出图案→退出后自动恢复
```
### 7.2 gen_bw_patterns.py / gen_solid_colors.py — 测试图生成
需 Pillow(`py -m pip install pillow`)。重新生成 `assets/` 下全部图案:
- `gen_bw_patterns.py` → 640x360 黑白图 ×5:
`bw_star.png` 西门子星(极限分辨率)、`bw_sweep.png` 频率扫描条纹(24px→3px)、
`bw_checker_sweep.png` 渐变棋盘(2→32px)、`bw_zoneplate.png` 波带片(各向混叠)、
`bw_testcard.png` 综合测试卡(灰阶/刻度/细棋盘/线宽组);
- `gen_solid_colors.py` → 800x600 纯色图 ×10(R/G/B 各 55/AA/FF + 三原色),
与 GUI 内置纯色按钮同源,供自定义栏位或其他工具加载。
### 7.3 la_wave_analyzer.py / la_wave_analyzer3.py — 逻辑分析仪波形判读
分析 Kingst VIS 导出的边沿流 CSV(列:`Time[s], 通道A, 通道B[, 通道C]`,
10ns 分辨率),按 50ms 窗口占空比签名自动分段,输出每段的签名(FF/55/AA/00)、
时长、行周期/有效区宽度/消隐(按 40MHz 像素时钟折算):
```
python la_wave_analyzer.py <capture.csv> # 2 通道(默认判读 B 口 D0/D1)
python la_wave_analyzer3.py <capture.csv> # 3 通道(RGB 三组同拍, ch8/9/10)
```
### 7.4 selftest_rs485.py — 光机协议自检(无硬件)
对照上游 `protocols.md` 实测帧向量回归帧构造/解析/译码:`python selftest_rs485.py`,
全部通过退出码 0。改 `dlpc_rs485.py` 后必须跑一遍。

从源码运行:`python src/hdmi_gui.py`,需 Python ≥3.10;EDID/命令行纯标准库;
GUI 需 customtkinter(`py -m pip install customtkinter`);光机控制需 pyserial;
自定义图片要 JPG/BMP/WebP 需可选 Pillow。
## 9. 构建与发布
```powershell
cd src
python selftest_rs485.py # 光机协议回归(改 dlpc_rs485.py 后必跑)
python build_exe.py # 打包 → ../release/DLPilot.exe(自动装 PyInstaller;
# 内置 pyserial/customtkinter, CTk 主题数据自动收集)
python build_exe.py --debug # 额外出一个带控制台的调试变体(--dump 可见输出)
python package_release.py 0.2.0 # 组装 release/DLPilot-v0.2.0-win64.zip
python publish_gitea.py DLPilot-v0.2.0-win64.zip --insecure # 上传 Gitea Release(需 GITEA_TOKEN)
```
## 10. 注意事项 / FAQ
- **光机没反应排查**:① 串口/波特率(115200 8N1)与 A/B 接线;② 先发 `M999` 验证链路;
③ 开光机回 0xFF 是 DLPC 就绪门禁——上电后等几秒;④ USB-RS485 转换器半双工,
发送时板上回包不会回环(正常);
- **exe 放只读目录会怎样**:自定义图片与 `pattern_slots.json` 写在 exe 旁边,只读目录会导致配置存不下;
- **重新打包后图标没变**:Windows 图标缓存,`ie4uinit -show` 或改个名即可;
- **多屏序号**:切分辨率前先确认显示器序号(GUI 下拉框与 `hdmi_source.bat -List` 输出一致);
- **残留进程**:修改源码重新打包前先结束残留的 DLPilot 进程(`build_exe.py` 会自动 taskkill);
- **改 logo**:改 `src/logos/logo_ph_orange.svg` → `python src/logos/make_ico.py` → 重新打包;
- **配置互不影响**:exe 与源码脚本各自按所在目录保存 `pattern_slots.json`,两份安装互不干扰。

# DLPilot — HDMI 源端调试 + 光机控制工具
> LT8619C(HDMI→RGB888)→ DLPC3421 投影转接板调试配套的 PC 端工具:
> HDMI **源端**(EDID 查看、分辨率切换、纯色/测试图案投屏)+ **光机控制**
> (RS485 直连板上 GD32 网关,开关光机/设光强/查温度电流)。
>
> - **只想用工具**:到 [Gitea Releases](https://gitea.hulk.wang/hulk/LT8619C_Debug_Tools/releases)
> 下载 `DLPilot-vX.Y.Z-win64.zip`,解压双击 `DLPilot.exe` 即可(Windows 10/11 x64,免安装、无需 Python)。
> - **要改代码/重新打包**:见 §8、§9。
>
> 更新:2026-09-11
---
## 1. 功能总览
| 功能 | 说明 |
|---|---|
| EDID 查看 | 枚举各显示输出口,从注册表读取 EDID 原始数据,按 EDID 1.4/CEA-861 解算:厂商/型号/尺寸/Gamma/输入类型/支持模式(DTD/已建立/标准/CEA-VIC)/首选时序完整参数/校验和 |
| EDID 逐字节解析 | "EDID 原始数据"框右上"逐字节解析"按钮:按偏移逐字段展开基础块与 CTA-861 扩展块,每字段附原始字节 hex;命令行等价 `--edid-fields` |
| 分辨率切换 | "分辨率"下拉列出显卡按该屏 EDID 提供的全部模式;**应用**=临时切换(不写注册表,重启/恢复即还原),**恢复**=回到本次会话切改前的模式 |
| 测试图案投屏 | 全屏投到所选显示器,测试卡区域可选 `640x360 / 800x600 / full 铺满`;内置 纯红/纯绿/纯蓝/黑白棋盘格/网格线 + R/G/B 三行 55/AA/FF 纯色值按钮 + 3 个自定义图片栏位 |
| 界面 | CustomTkinter 深色双栏仪表盘(左列 HDMI 源端 / 右列 光机控制),顶栏可切换 Dark/Light/System |
| 光机控制 | RS485 → 板载 GD32E230 网关 → DLPC3421:开关光机(可定时)、设光强、查电流/温度/版本、TEC 控制、软件重启;光强/定时提供快捷滑条;收发日志带协议译码(见 §5) |
| 智能显示拓扑 | 仅当检测到转接板(EDID 厂商 "XLS")接入但未进入桌面(Windows 卡在"仅电脑屏幕")时才强制扩展把它拉回;你主动选的"仅第二屏幕"等拓扑不会被改动 |
| 命令行模式 | 全部功能可脚本化调用,供自动化测试(见 §6、§7) |
| 波形分析脚本 | 逻辑分析仪 CSV 波形按占空比签名分段,输出行结构/占空比/消隐明细(见 §7.3) |
## 2. 下载与安装
1. 打开 [Releases 页面](https://gitea.hulk.wang/hulk/LT8619C_Debug_Tools/releases),取最新的
`DLPilot-vX.Y.Z-win64.zip`;
2. 解压到**任意可写目录**(自定义图片与栏位配置会写到 exe 旁边);
3. 双击 `DLPilot.exe`。首次启动比脚本慢一两秒(onefile 解压),属正常现象。
包内包含:
```
DLPilot/
├── DLPilot.exe 主程序(单文件自包含, 光机控制的 pyserial 已内置)
├── pattern_slots.json 预置自定义栏位 + 串口记忆
├── bw_*.png ×5 640x360 黑白测试图
├── solid_*.png ×10 800x600 纯色测试图
└── README.md 本说明
```
## 3. GUI 使用
主窗口为双栏仪表盘(布局设计稿:`UI参考布局.svg`),默认跟随系统深/浅色外观
(顶栏可切换 Dark/Light/System),顶栏右侧"关于"按钮内含软件信息:
```
左列(HDMI 源端) 右列(光机控制 RS485)
┌ 显示器选择区域 [刷新] ┐ ┌ 串口选择 + 波特率/8-N-1 参数/连接 ┐
├ 支持的模式: 分辨率[应用][恢复] + 明细 ┐ ├ 串口数据 — 收发日志(译码+hex) ┤
├ EDID 信息(表格) ┘ ├ 光机命令 — 快捷按钮+TEC │
├ 测试图案 / 纯色 / 自定义 / 测试卡区域 │ 预设下拉 / 自定义 / 温度读取 │
├ EDID 原始数据 [逐字节解析] ┘ └ 快捷滑条 — 光强/定时/TEC温度 ┘
```
1. 左上显示器下拉选择目标屏(多屏时注意别选成主屏),"刷新"重新枚举;
2. **切分辨率**:"支持的模式"卡片里选模式 → "应用";测完点"恢复";
3. **投测试图**:"测试图案"卡片先选**测试卡区域**(640x360 / 800x600 / full)→
点图案按钮全屏投放,按 **ESC** 或点击退出;R/G/B 纯色按钮(55/AA/FF,按通道着色)
用于 RGB 位交换类测试;自定义图片点齿轮按钮配置(图片自动复制到 exe 旁),
"校准图案"一排为 3D 光固化测试/校准图预留槽位;
4. **光机控制**:右列选串口与参数(波特率/数据位/校验/停止位,默认 115200 8-N-1)→ 连接 →

(200-350 即 20.0-35.0°C)后"下发温度值";数值框输入后回车自动限幅同步;
5. 测试卡区域、自定义栏位与串口记忆(含参数)自动保存在 exe 旁的 `pattern_slots.json`。
## 4. 典型测试场景
```
1. HDMI 接转接板 → 启动 DLPilot → 刷新 → 选中板卡显示器
2. 板卡 shadow EDID 首选 640x360@60 → 测试卡区域选 640x360(与光机面板原生 1:1)
3. "光机控制"连接串口 → M999 查版本确认链路通 → M730S0 开光机
4. 点 R/G/B 行纯色按钮投图 → 目视/逻辑分析仪核对 RGB888 输出
- 纯红/绿/蓝:验证通道映射(R=D[23:16], G=D[15:8], B=D[7:0])
- 55/AA 对:验证位交换(0x606E)——图像应为 50% 灰阶占空比
5. M731S100 设光强 → M732 查电流读回复核 → M730S1 关光机
```
寄存器语义(0x606E 位交换 / 0x606D 整组顺序)与光机协议的判读基线见上游主仓库
[LT8619C_DLPC3421_HDMI](https://gitea.hulk.wang/hulk/LT8619C_DLPC3421_HDMI) 的 `doc/architecture/`。
## 5. 光机控制(RS485 → GD32 网关 → DLPC3421)
物理链路:PC 经 **USB-RS485 转换器**接板卡 A/B 端子,板上 GD32E230 做 RS485→I2C 网关
控制 DLPC3421(I2C 地址 0x1B)。串口参数 **115200, 8N1**,协议细节以上游固件仓
`protocols.md` 为准:命令帧 `D5 01 LEN <ASCII命令> CRC`、响应帧 `B5 TYPE LEN <payload> CRC`,
CRC 为第 2 字节起累加和取低 8 位。
GUI"光机控制"区:选串口 → 连接 → 点快捷按钮或命令下拉/自定义输入发送;串口下拉显示
"COMx + 设备描述",CH344 等多路适配器每一路描述不同(如 serial-A/B/C/D),据此选口;
多口描述相同时自动附物理位置消歧。日志区实时显示 `→ 命令` / `← 译码结果 (原始 hex)`,
错误自动附释义(如 `err:3(I2C NACK)`)。
| 命令 | 功能 | 响应示例 |
|---|---|---|
| `M730S0` / `M730S1` | 开 / 关光机 | `ok` |
| `M730S0T2000` | 开光机并定时 2000ms 自动关(≤32700) | `ok`(期间 M737 延迟应答) |
| `M731S100` | 设光强 54-800(RGB 同值,写后读回复核) | `ok` / `err:R..G..B..` |
| `M732` | 查三路电流设置值(0-65535) | `okR110G110B110` |
| `M201` / `M202` | 查 DMD / LAMP 温度(0.1°C) | `okTL:246` = 24.6°C |
| `M999` | 查固件版本 | `okv20.0.0.1` |
| `M737` | 查投光是否结束(投光中延迟应答) | `ok` |
| `M7S0` / `M7S1` | TEC 自动控温开 / 关(注意 S0=开) | `ok` |
| `M8S330` | TEC 凝露点 33.0°C(200-350,0.1°C) | `ok` / `err:OL` |
| `M1` | 协议握手 | `ok` |
| `M888` | 软件重启 | `ok` 后 100ms 复位 |
注意:**DLPC3421 启动完成前 M730/M731/M732 被就绪门禁拒绝**(回 0xFF),上电后稍等几秒再发。
命令行等价(源码方式):
```
python hdmi_gui.py --port COM9 --dlpc-cmd M730S0 --dlpc-cmd M999
逐条发送并打印译码响应
```
## 6. 命令行模式(hdmi_gui.py)
exe 版无控制台,`--dump/--edid-fields` 的输出不可见(`--dlpc-cmd` 仍可执行,靠退出码判断),
调试请用源码方式:
```
python hdmi_gui.py --dump 控制台输出 EDID 解算
python hdmi_gui.py --edid-fields 控制台输出 EDID 逐字节字段解析表
python hdmi_gui.py --test-pattern Blue --area 800x600 --seconds 5
出图 5 秒自动退出
python hdmi_gui.py --test-pattern Custom1 投自定义栏位 1
python hdmi_gui.py --port COM9 --dlpc-cmd M730S0 RS485 发光机命令(可多次)
python hdmi_gui.py --seconds 5 GUI 冒烟测试, 5 秒自动关
--test-pattern {Red,Green,Blue,Checker,Grid,Custom1..3}
--area {640x360,800x600,full} --monitor N --seconds S
--port COMx --baud 115200 --dlpc-cmd CMD(可重复; 任一命令失败退出码 1)
```
## 7. 辅助脚本(src/ 下)
### 7.1 hdmi_source.bat / .ps1 — 源端命令行工具
与 GUI 互补,适合脚本串联:
```
tools\hdmi_source.bat -List 枚举显示器与支持分辨率(验证 EDID)
tools\hdmi_source.bat -Monitor 1 -Mode 800x600 切模式
tools\hdmi_source.bat -Mode 800x600 -Pattern -Restore
切模式→出图案→退出后自动恢复
```
### 7.2 gen_bw_patterns.py / gen_solid_colors.py — 测试图生成
需 Pillow(`py -m pip install pillow`)。重新生成 `assets/` 下全部图案:
- `gen_bw_patterns.py` → 640x360 黑白图 ×5:
`bw_star.png` 西门子星(极限分辨率)、`bw_sweep.png` 频率扫描条纹(24px→3px)、
`bw_checker_sweep.png` 渐变棋盘(2→32px)、`bw_zoneplate.png` 波带片(各向混叠)、
`bw_testcard.png` 综合测试卡(灰阶/刻度/细棋盘/线宽组);
- `gen_solid_colors.py` → 800x600 纯色图 ×10(R/G/B 各 55/AA/FF + 三原色),
与 GUI 内置纯色按钮同源,供自定义栏位或其他工具加载。
### 7.3 la_wave_analyzer.py / la_wave_analyzer3.py — 逻辑分析仪波形判读
分析 Kingst VIS 导出的边沿流 CSV(列:`Time[s], 通道A, 通道B[, 通道C]`,
10ns 分辨率),按 50ms 窗口占空比签名自动分段,输出每段的签名(FF/55/AA/00)、
时长、行周期/有效区宽度/消隐(按 40MHz 像素时钟折算):
```
python la_wave_analyzer.py <capture.csv> # 2 通道(默认判读 B 口 D0/D1)
python la_wave_analyzer3.py <capture.csv> # 3 通道(RGB 三组同拍, ch8/9/10)
```
### 7.4 selftest_rs485.py — 光机协议自检(无硬件)
对照上游 `protocols.md` 实测帧向量回归帧构造/解析/译码:`python selftest_rs485.py`,
全部通过退出码 0。改 `dlpc_rs485.py` 后必须跑一遍。

从源码运行:`python src/hdmi_gui.py`,需 Python ≥3.10;EDID/命令行纯标准库;
GUI 需 customtkinter(`py -m pip install customtkinter`);光机控制需 pyserial;
自定义图片要 JPG/BMP/WebP 需可选 Pillow。
## 9. 构建与发布
```powershell
cd src
python selftest_rs485.py # 光机协议回归(改 dlpc_rs485.py 后必跑)
python build_exe.py # 打包 → ../release/DLPilot.exe(自动装 PyInstaller;
# 内置 pyserial/customtkinter, CTk 主题数据自动收集)
python build_exe.py --debug # 额外出一个带控制台的调试变体(--dump 可见输出)
python package_release.py 0.2.0 # 组装 release/DLPilot-v0.2.0-win64.zip
python publish_gitea.py DLPilot-v0.2.0-win64.zip --insecure # 上传 Gitea Release(需 GITEA_TOKEN)
```
## 10. 注意事项 / FAQ
- **光机没反应排查**:① 串口/波特率(115200 8N1)与 A/B 接线;② 先发 `M999` 验证链路;
③ 开光机回 0xFF 是 DLPC 就绪门禁——上电后等几秒;④ USB-RS485 转换器半双工,
发送时板上回包不会回环(正常);
- **exe 放只读目录会怎样**:自定义图片与 `pattern_slots.json` 写在 exe 旁边,只读目录会导致配置存不下;
- **重新打包后图标没变**:Windows 图标缓存,`ie4uinit -show` 或改个名即可;
- **多屏序号**:切分辨率前先确认显示器序号(GUI 下拉框与 `hdmi_source.bat -List` 输出一致);
- **残留进程**:修改源码重新打包前先结束残留的 DLPilot 进程(`build_exe.py` 会自动 taskkill);
- **改 logo**:改 `src/logos/logo_ph_orange.svg` → `python src/logos/make_ico.py` → 重新打包;
- **配置互不影响**:exe 与源码脚本各自按所在目录保存 `pattern_slots.json`,两份安装互不干扰。

<#
.SYNOPSIS
HDMI 源端测试工具 —— 枚举/切换输出分辨率 + 全屏测试图案
.DESCRIPTION
配合 LT8619C(HDMI 转 RGB888)→ DLPC3421 转接板调试使用。
原理:电脑显卡通过 HDMI DDC 读取转接板 EDID 来枚举可用分辨率,
本脚本调用 Win32 API 完成模式枚举与切换,再用 WinForms 全屏窗口
输出测试图案。板载 EDID 只声明了 640x360@60(25.2MHz 像素时钟),
插上 HDMI 后显卡应只能发这一个模式;-List 可直接验证 EDID 是否生效。
测试图案用途:
Bars 100% 彩条 —— 肉眼/示波器验证 RGB 通道顺序与极性
GraySteps 16 级灰阶 —— 验证 RGB888 各 bit 连通性
Gradient R/G/B 三段渐变 —— 验证每通道 8bit 线性度
Checker 黑白棋盘格 —— 验证像素时钟 PCLK 与 DE 对位
Grid 网格+中心十字 —— 验证像素映射/偏移/缩放
Red/Green/Blue/White/Black/Gray50 纯色 —— 万用表/示波器测单通道电平
全屏窗口操作:空格或→下一图案,←上一图案,ESC 退出。
.EXAMPLE
tools\hdmi_source.bat -List
枚举所有活动显示器与显卡支持的分辨率(验证 EDID)
.EXAMPLE
tools\hdmi_source.bat -Monitor 1 -Mode 640x360
把显示器 1 切到 640x360(缺省 60Hz,可写 640x360@60)
.EXAMPLE
tools\hdmi_source.bat -Mode 640x360 -Pattern -Restore
切到 640x360 并全屏出图案,退出图案后恢复原分辨率
.EXAMPLE
tools\hdmi_source.bat -Pattern -PatternName Checker -Seconds 5
当前分辨率下全屏棋盘格,5 秒后自动退出(自动化测试用)

# I2C-Inject — LT8619C 寄存器择机注入工具
> 更新:2026-09-03。由两部分组成:**RP2040 注入器固件**(`mcu-rp2040/`,刷入
> BPI-Pico-RP2040,MicroPython)+ **PC 端 GUI**(`i2c_inject_gui.py` / 打包版
> `I2C-Inject.exe`)。可在 LT8619C demo 板的 I2C 总线上安全地在线读写寄存器。
> 固件细节、刷写步骤与串口命令详见 [mcu-rp2040/README.md](mcu-rp2040/README.md)。
---
## 1. 工作原理(为什么不会和 demo 板冲突)
demo 板 MCU 每 ~500ms 轮询一次 LT8619C。注入器的时序:
```
监听总线边沿 -> 等下一轮活动结束 -> 总线静置 50ms -> 发射
(切 bank -> 写 -> 读回校验), 失败自动重试 3 次 -> 立即释放总线回监听
```
静置窗口落在两次轮询之间的 ~490ms 空窗内,单次注入序列 <2ms,冲突概率趋近零;
即使撞上也表现为读回不符,自动重试覆盖。板载 LED:**常亮 = 监听中**,上电快闪 3 次 = 自检。
## 2. 硬件准备
| RP2040 板 | 接 LT8619C 总线 |
|---|---|
| GP8(物理脚 11) | SDA |
| GP9(物理脚 12) | SCL |
| GND | GND |
- **不接 VCC、不外加干扰**:总线由 demo 板自带上拉(先确认上拉为 3.3V)
- 固件分两层:MicroPython 运行时 UF2 + 注入器应用脚本(上传为板上 `main.py` 自启动)
——完整刷写步骤、串口命令表、工作机制见 [mcu-rp2040/README.md](mcu-rp2040/README.md)
- 固件内置 viper 编译的总线嗅探(`c [ms]` 命令,~3MHz 采样),串口回吐边沿数据可离线解码 I2C
## 3. GUI 使用
双击 `I2C-Inject.exe`(或 `python i2c_inject_gui.py [COMx]`):
1. **第一排左侧**:串口下拉 →"刷新"扫描 → 选中注入器端口 →"连接"(日志出现"已连接")
2. **第一排右侧**:输入 Bank/寄存器/值(十六进制)→ **写入**(自动读回校验)/**读取**
3. **0x606E 快捷块**(位交换,语义为 demo 板 LA 实测):
- `00`=关交换;`20`=镜像 D[7:0](载蓝色分量的组,实测立即生效)
- `40`/`80`=另外两组(demo 板未单独实测,自板点亮时验证)
4. **0x606D 快捷块**(RGB 整组顺序,蓝+红双色实测=手册 naive 读法):
- `00 BGR / 03 BRG / 04 GBR / 05 GRB / 06 RBG / 07 RGB`
- 字母串顺序 = D[23:16]/D[15:8]/D[7:0] 携带的分量;切换实时生效,不影响 HDMI 锁定
5. 回显格式:`=` 正常结果(绿色,含"读回=xx"校验值)、`!` 告警/失败(橙色)
6. 收尾:把改过的寄存器写回原值(0x606E 原值 00;0x606D 原值 07)
## 4. 已实测的寄存器事实速查(demo 板)
| 寄存器 | 实测结论 |
|---|---|
| 0x606E | bit5(0x20)=镜像 D[7:0](蓝值组),立即生效、含消隐码;bit7(0x80) 对该组无效;稳态下写入可持续(实测 6.7s+),板子非稳态时 0.3~0.5s 内被刷回 00 → **先投图等稳态再写,写完立即读回确认** |
| 0x606D | 000/001/010=BGR、011=BRG、100=GBR、101=GRB、110=RBG、111=RGB(字母串=D[23:16]/D[15:8]/D[7:0]),切换实时生效;demo 板 init 值 07 |
## 5. 目录内容
| 文件 | 用途 |
|---|---|
| `I2C-Inject.exe` | 打包好的单文件 PC 端 GUI(需 pyserial,已打包在内) |
| `i2c_inject_gui.py` | PC 端 GUI 源码(`python build_exe.py` 重新打包) |
| `mcu-rp2040/` | RP2040 总线端:注入器固件脚本 + MicroPython 运行时 UF2 + 刷写说明(README) |
| `logos/` | 图标源文件与 `make_ico_i2c.py`(改 logo 后重跑再打包) |
## 6. 故障排查
- 写入回显 `OK 读回=xx` 但稍后读回变了 → demo 板把它刷回了(见 §4 稳态提醒),先确认 HDMI 已稳定出图
- 读寄存器 NAK/失败 → 检查三根接线与共地;用 `s` 命令看边沿计数是否在增长(增长=监听正常,总线有活动)
- 串口列表空白 → 换 USB 口/检查设备管理器(应出现 `USB 串行设备`,VID_2E8A)

# mcu-rp2040 — RP2040 注入器固件
本目录存放 **I2C-Inject 的总线端**:跑在 BPI-Pico-RP2040(RP2040 + MicroPython)上的
注入器应用脚本,以及配套的 MicroPython 运行时 UF2。
> PC 端 GUI 见上级目录 [../README.md](../README.md)。两者通过 USB 虚拟串口通信。
## 1. 文件说明
| 文件 | 用途 |
|---|---|
| `rp2040_inject.py` | 注入器应用(MicroPython 脚本)。上传为板上 `main.py`,上电自启动 |
| `RPI_PICO-20260824-v1.29.0.uf2` | MicroPython 运行时(标准 RP2040 构建,v1.29.0,2026-08-24)。首次使用或升级时刷 |
⚠️ UF2 必须是 **RPI_PICO** 标准构建(RP2040 芯片);`PICO_W`(带 WiFi 芯片)与
`RPI_PICO2`(RP2350 芯片)变体不可用。
## 2. 硬件与接线
| BPI-Pico-RP2040 | 接 LT8619C 总线 | 说明 |
|---|---|---|
| GP8(物理脚 11) | SDA | 平时高阻输入只听,注入时才驱动 |
| GP9(物理脚 12) | SCL | 同上 |
| GND | GND | 必须共地 |
- **不接 VCC/3V3**(各喂各的电)、**不外加任何上拉电阻**(总线用 demo 板自带上拉)
- 动手前确认总线上拉电平为 3.3V(RP2040 不耐 5V)
## 3. 刷写步骤
```text
① 刷 MicroPython 运行时(首次/升级):
按住板上 BOOTSEL 键插入 USB → 出现 RPI-RP2 U 盘
→ 把 RPI_PICO-20260824-v1.29.0.uf2 拖入 → 自动重启
⚠ 刷 UF2 可能重建板载文件系统, 之后需重传 ② 的 main.py
② 上传注入器应用(每次刷 UF2 后, 或应用更新后):
py -m pip install mpremote
py -m mpremote connect COMx cp rp2040_inject.py :main.py
py -m mpremote connect COMx reset # 复位, main.py 自启动
③ 验证: 串口终端(任意波特率)应看到
LT8619C 注入器就绪 GP8=SDA GP9=SCL 100kHz addr 0x32
```
**LED 状态**:上电快闪 3 次 = 自检;**常亮 = 总线监听中**。
## 4. 串口命令(USB CDC,十六进制参数,一行一令)
| 命令 | 功能 | 回显示例 |
|---|---|---|
| `w <bank> <reg> <val>` | 择机写 + 读回校验 | `= w 60 6E 80 : OK 读回=80` |
| `r <bank> <reg>` | 择机读 | `= r 60 6E : OK 00` |
| `s` | 总线边沿计数(接好线后在涨 = 监听正常) | `= 边沿计数 2958` |
| `c [ms]` | 嗅探捕获(默认 700ms),输出边沿时间戳供离线解码 I2C | `= capture 1207 edges / 700 ms` + `C` 行 |
| `?` | 帮助 | |
- 回显行首:`=` 正常结果 / `!` 告警(校验不符、总线错误、静置超时)
- 读回不符(被 demo 板 MCU 插队)会自动整组重试,最多 3 次
## 5. 工作机制(择机注入)
```
监听 SDA/SCL 边沿(双沿中断) → 等下一轮总线活动出现
→ 活动结束后总线静置满 50ms → 立即发射:
START→[bank 写]→START→[reg/数据 写]→RESTART→[读回]→STOP
→ 成功/失败(重试) → 立即释放总线回监听
```
- demo 板 MCU 以 ~500ms 周期轮询,注入序列 <2ms,落在周期间空窗内冲突概率趋近零
- 嗅探捕获采用 viper 裸指针读 GPIO(~0.27µs/次 ≈ 3MHz 采样),字节码路径仅 ~12µs/次(会混叠)作兜底
## 6. 已知实测行为(demo 板)
- 0x606E:bit5(0x20) 镜像 D[7:0](蓝值组)立即生效;板子非稳态时 0.3~0.5s 内会被其固件刷回 0x00
→ **先投图等稳态再写,写完立即读回确认**
- 0x606D:000/001/010=BGR、011=BRG、100=GBR、101=GRB、110=RBG、111=RGB(字母串=
D[23:16]/D[15:8]/D[7:0] 分量顺序),切换实时生效,不影响 HDMI 锁定
- 过程数据与完整规程见上游主仓库 `doc/architecture/rgb_bit_swap_test.md`

# LT8619C_Debug_Tools # LT8619C_Debug_Tools
本仓库用存储LT8619C调试过程中需要的一些小工具(包括AI生成) LT8619C(HDMI→RGB888)→ DLPC3421 投影转接板调试配套上位机工具集。
上游主仓库(固件):[LT8619C_DLPC3421_HDMI](https://gitea.hulk.wang/hulk/LT8619C_DLPC3421_HDMI)。
## 工具一览
| 工具 | 用途 | 获取 |
|---|---|---|
| [DLPilot](DLPilot/) | HDMI 源端(EDID 查看/逐字节解析、分辨率切换、纯色与测试图案全屏投屏)+ 光机控制(RS485→GD32 网关→DLPC3421:开关光机/设光强/查温度电流) | 到 [Releases](https://gitea.hulk.wang/hulk/LT8619C_Debug_Tools/releases) 下 `DLPilot-vX.Y.Z-win64.zip`,解压即用;详见 [DLPilot/README.md](DLPilot/README.md) |
| [I2C-Inject](I2C-Inject/) | LT8619C 寄存器在线读写:RP2040 注入器在 demo 板 I2C 总线上择机注入(避让主控轮询,写后自动读回校验) | 需配合 RP2040 固件 `rp2040_inject.py`;详见 [I2C-Inject/README.md](I2C-Inject/README.md) |
## 环境要求
- 发布版 zip 开箱即用(Windows 10/11 x64,无需安装 Python)
- 源码运行:Python ≥3.10;DLPilot 命令行/EDID 纯标准库,GUI 需
`py -m pip install customtkinter`(自定义图片 JPG/BMP 可选 Pillow、光机控制可选 pyserial);
I2C-Inject 需 `py -m pip install pyserial`
- 重新打包:`DLPilot/src/build_exe.py`(自动安装 PyInstaller);I2C-Inject 目录内 `python build_exe.py`
## 目录结构
每个工具内统一三区:**src/ 源代码(人写)** → **assets/ 生成资产(可再生成)** →
**release/ 打包与发布产物(机器生成)**;README.md 面向使用者,AGENTS.md 面向 AI/Agent(工程约定与构建规程)。
```

## 发布流程(DLPilot)
```powershell
cd DLPilot/src
python build_exe.py # 打包 → ../release/DLPilot.exe
python package_release.py <版本> # → ../release/DLPilot-v<版本>-win64.zip
python publish_gitea.py DLPilot-v<版本>-win64.zip --insecure # 上传 Gitea Release(需 GITEA_TOKEN)
```
## 备注
- 源码与打包产物(exe、pattern_slots.json)均入库;发布 zip 不入库,只上传 Gitea Release
- 两件工具的寄存器语义(0x606E 位交换 / 0x606D 整组顺序)均经 demo 板逻辑分析仪
