整数定点3D旋转渲染，参考安富莱STM32H7例程（本质是Pawel A. Hernik的开源算法）移植； 点一下屏幕还能切到SD卡JPEG逐帧视频播放。
ESP32-2432S028R (CYD) TFT_eSPI网页烧录已实测 定点数学3D渲染 SPI 80MHz SD卡+TJpg_Decoder 触摸切换单立方体 / 十字形复合体 / 花瓣状复合体 / 3x3立方体阵列，每6秒自动切换。
3种像素图案 + 1种星空穿梭 + 1种棋盘格，跟模型一起自动循环。
40MHz起步~28fps，实测提到80MHz后~52fps；测过100MHz发现帧率跟80MHz完全一样，验证了80MHz正好是ESP32 APB总线本身的硬件天花板。
同一份固件加了SD卡JPEG逐帧播放模式，点一下屏幕在3D演示和视频播放之间切换。
核心渲染算法（定点sin/cos查表、无浮点、逐行光栅化、背面剔除、Z排序）来自 Pawel A. Hernik 2019年的开源项目 "3D Filled Vector Graphics"（原本面向Arduino+ST7735小屏）， YouTube演示。 参考资料里安富莱STM32H7 800x480裸机版本把这个算法原样保留，只是换了显示输出； 这次移植到本板（320x240）时同样原样保留了顶点/面/配色数据和光栅化算法，只换了 屏幕尺寸和显示驱动（STM32的LTDC+DMA2D换成TFT_eSPI的pushImage）。
屏幕（ST7789，跟同目录03/04工程一致）：
| 信号 | GPIO |
|---|---|
| MOSI | IO13 |
| SCLK | IO14 |
| CS | IO15 |
| DC | IO2 |
| BL(背光) | IO21 |
SD卡（走ESP32默认VSPI硬件引脚，跟屏幕是两条独立总线不冲突）：
| 信号 | GPIO |
|---|---|
| CS | IO5 |
| SCK | IO18 |
| MISO | IO19 |
| MOSI | IO23 |
SD卡引脚依据是厂商原理图（ESP32-2432S028-MCU.jpg 的SD_Car部分）和厂商自带demo
（6_1_SD_Jpg）两处互相印证，不是网上通用资料猜的。
触摸中断脚： IO36，只用来判断"有没有点一下屏幕"（IRQ被拉低），
不解析XPT2046坐标——点屏幕任意位置都能触发3D/视频模式切换。
| SPI时钟 | 单帧耗时 | 帧率 | 备注 |
|---|---|---|---|
| 40MHz | ~35ms | ~28fps | 沿用同目录其它工程的默认值 |
| 80MHz | ~19ms | ~52fps | 实机长时间点亮确认不花屏 |
| 100MHz | ~19ms | ~52fps | 跟80MHz完全一样，证实80MHz是硬件上限（等于ESP32 APB总线时钟本身） |
瓶颈是SPI往屏幕搬像素数据的带宽，不是ESP32算3D的算力——这份demo每帧要把 320x240整屏像素全部重画（背景铺满+3D图形），跟B站上常见的"STM32F103C8T6+ST7735 实现80帧"对比不公平：那块屏只有128x160（约2万像素），这块屏是320x240（约7.7万像素）， 要搬的数据量差了将近4倍。
ESP32算力和内存都不够直接解码标准视频编码（H.264等），做法是先把视频转成 一串JPEG图片（逐帧），存到SD卡，固件按顺序读一张画一张，靠固定的帧间隔造出 "播放视频"的效果，本质是快速幻灯片，不是真正的视频解码器。
Blender基金会官方开放电影《Big Buck Bunny》（CC BY 3.0），剪了40秒高潮片段。
320x160，320张JPEG，共3.9MB，存在SD卡 /bbb/ 目录下（原始素材是180高，sprite内存踩坑后缩到160，见下面"踩坑记录"）。
用 TJpg_Decoder 解码进一块320x160的离屏sprite，解完整块一次性推上屏，不会露出解码到一半的中间状态。
点一下屏幕（判断IO36触摸中断脚），在3D演示和视频播放两个模式之间切换。
署名要求：Big Buck Bunny 是 CC BY 3.0 协议，免费能用，但公开发布时按协议要求 署名 "Blender Foundation | bigbuckbunny.org"。
| 问题 | 原因 | 解决 |
|---|---|---|
| 串口上传帧序列，每个文件都缺字节 | ESP32默认串口接收缓冲只有256字节，SD写入阻塞时被写爆丢数据 | 接收端Serial.setRxBufferSize(16384) |
| 切帧时画面闪黑 | 解码块直接画在屏幕上，能看到"旧帧被新帧一块块覆盖"的中间过程 | 先解码进离屏sprite，解完整块一次性pushSprite |
| 加上sprite后视频模式直接黑屏卡死 | 320x180的sprite要115200字节，但堆内存碎片化，最大连续块只有110580字节，createSprite失败 | sprite高度缩到160（102400字节），牺牲一点底部裁切换空间 |
| 播放速度只有~4fps，达不到预期 | SD默认用保守的4MHz初始化 | 提到25MHz，解码耗时226ms降到~140ms（~6-7fps）；测过40MHz没有进一步提升，瓶颈变成JPEG解码本身的算力 |
完整版实拍演示+源码解说（11分19秒），前半段实机效果，后半段逐行代码拆开讲：
下面是桌面仿真渲染器跑出来的干净素材（跟固件用同一套定点数学和同一份数据， 只是没有实拍摄像头的反光/摩尔纹），横版1920x1080，覆盖全部4种模型x5种背景组合， 配了一段自己合成的原创8-bit背景音乐（纯波形生成，没有版权问题）：
跟实拍对比一下——下面这张是SD卡视频播放模式的实机照片，同样是Big Buck Bunny的画面：
下面是这个项目当前的完整源码，跟仓库里
02_Arduino源码/ESP32_3D_Rotation/src/main.ino 保持同步，可以直接在这页上对着看，
不用另外下载工程。前段的顶点/花纹数据是数值表，篇幅比较长，直接往下滚就能跳过。

ESP32-2432S028R (CYD, 2.8寸黄屏) 整数定点 3D 旋转演示
算法来源：Pawel A. Hernik, "3D Filled Vector Graphics" (2019)
YouTube: https://youtu.be/5y28ipwQs-E
原版面向 Arduino + ST7735，无浮点、无三角函数库，靠查表 sin/cos + 扫描线
光栅化实现平面填色的旋转多面体。
本文件移植自参考资料里安富莱 STM32H7 800x480 裸机版本
(../01_参考资料/基于H7的3D旋转裸机移植（800x480）.7z, User/3DTest.c)，
顶点/面/配色数据和光栅化算法原样保留，改动的地方：
- 屏幕尺寸从 800x480 换成本板 320x240 (landscape)
- 显示驱动从 STM32 LTDC+DMA2D 换成 TFT_eSPI 的 pushImage 分行刷屏
- setup()/loop() 换成 Arduino 框架写法，用 millis() 做切换计时
- 原来 STM32 例程里没用到的摇杆/按键/串口调试代码删掉了
硬件：ST7789 320x240 (setRotation(1))，接线沿用同目录下其它工程的
标准引脚（见 02_所需库与配置/platformio.ini）。

见 下载完整烧录包 ZIP，提供四种方式，按自己趁手的选一种就行：
打开 01_Arduino_INO 里的 .ino，板子选普通ESP32 Dev Module，直接编译上传。
02_PlatformIO_Project 完整工程，pio run --target upload 一条命令搞定。
03_BIN_Firmware 下已编译好的 .bin，不用装Arduino IDE，直接用esptool烧。
打开网页烧录器（已实测），浏览器里点按钮就能烧，什么软件都不用装。
网页烧录器使用提醒：只支持电脑端Chrome/Edge浏览器（基于Web Serial API）；客户直接从本站打开即可。本地离线测试时要起静态服务器打开（python -m http.server 8080），不能直接双击html文件。USB线必须是数据线，充电线没有数据针脚，电脑设备管理器里不会出现串口。
✓ 已实测通过：普通ESP32通过网页一键烧录merged_firmware_0x0.bin成功，写入437760字节，耗时约24.8秒。
