01 / 项目概览

一块小设备。
做好一件小事。

围绕实时服务器监控、网络连接和轻量嵌入式界面，重新设计的 AI Passport 固件项目。

它把设备与我的基础设施连接起来，让重要的系统信息从服务器实时来到一块实体小屏幕上。

02 / 最初的想法

换一种方式
让屏幕融入日常。

课表实验给这块设备安排了一件安静的小事。这次重构换了一个问题：如果同一块小屏幕，也能显示远端系统的状态呢？

于是，CPU、内存、磁盘和网络读数有了一个实体落点。不用再打开完整的监控面板，抬眼就能看见。

03 / 架构

用简单的路径
把数据带到屏幕上.

02WSS / HTTPS实时推送 + 后备连接

03共享状态校验并保留

04小屏幕清晰地显示状态

WSS 是主要连接，HTTPS 轮询提供后备通道。两者更新同一份经过校验的状态，切换传输方式时，界面无需跟着切换。

数据过期或连接离线时，最后一组有效读数仍会保留在屏幕上。

04 / 技术细节

看看实验的内部。

设备: FoloToy AI Passport · ESP32-C3 · 8 MB Flash
显示屏: 240 × 320 · LVGL
固件: ESP-IDF · 独立应用，保留原有板级支持层
连接方式: Wi-Fi · WSS 主连接 · HTTPS 后备连接
界面: 概览、性能、网络、服务、设备和设置
数据处理: 校验后的快照、连接状态与固定长度的历史缓冲区

这是一个仍在演进的固件实验。当前源码已包含初次架构发布后的启动修复，请使用仓库当前的 main 分支。更全面的设备验证仍在进行。

01 / OVERVIEW

One small device.
A focused purpose.

A redesigned AI Passport firmware project built around real-time server monitoring, connectivity, and a lightweight embedded interface.

It connects the device with my own infrastructure so that important system information can move from a server to a small physical screen in real time.

02 / IDEA

A different kind
of everyday screen.

The Schedule experiment gave the device a quiet job. This rebuild asks a different question: what if the same small screen could show the state of a system somewhere else?

The result is a physical place for CPU, memory, disk, and network readings — something to glance at without opening another full-sized dashboard.

03 / ARCHITECTURE

A simple path
from data to display.

02WSS / HTTPSLive stream + fallback

03Shared stateValidate and retain

04Small screenRender a clear view

WSS is the primary connection. HTTPS polling provides a fallback. Both update the same validated state, so a change of transport does not require a different interface.

The last valid readings remain visible when data becomes stale or the connection goes offline.

04 / TECHNICAL DETAILS

Inside the experiment.

Device: FoloToy AI Passport · ESP32-C3 · 8 MB Flash
Display: 240 × 320 · LVGL
Firmware: ESP-IDF · independent application with the original board support layer
Connectivity: Wi-Fi · WSS primary · HTTPS fallback
Interface: Overview, Performance, Network, Services, Device and Settings
Data handling: Validated snapshots, connection states and a fixed history buffer

This is an evolving firmware experiment. Current source includes the startup repair after the initial architecture release; use the repository’s current main branch. Broader device validation remains ongoing.
