KryonOS v2.0.0 Roadmap: Major Features & Upcoming Changes

[Haris16-code]

🌐 Wi-Fi, Web Networking & KryonMail

KryonOS is getting full online connectivity. In v2.0.0, we are introducing native Networking & Web APIs directly into the runtime:

• Seamless Web Connectivity: Apps can easily send HTTP/HTTPS requests, fetch remote JSON data (weather forecasts, crypto feeds, device telemetry), and interact with real-time web services using standard JavaScript.
• Built-in Email App (KryonMail): We are shipping a dedicated, pre-installed email client named KryonMail, powered directly by HarisLab Connect. You will be able to compose and send emails straight from your ESP32 handheld without manually dealing with raw SMTP protocols.

⚡ Hardware Acceleration & High-Performance Math

• Hardware-Accelerated Math (300% to 800% Performance Boost): In v1.0.0, math operations are interpreted sequentially inside the Duktape bytecode engine. In v2.0.0, we are offloading mathematical routines to the ESP32’s native hardware Floating-Point Unit (FPU) and optimized C++ pipelines, delivering a massive 300% to 800% speedup for 3D graphics, transforms, and game physics.
• Silicon Cryptography Acceleration: New native cryptographic APIs expose the ESP32’s onboard silicon acceleration for AES, SHA, and RSA operations. Apps can sign payloads, verify signatures, and encrypt communications quickly with minimal CPU strain.

🎛️ Hardware I/O Expansion: Native PWM & I2C Ecosystem

• Native PWM Controls: Leverage the ESP32's built-in LEDC hardware peripheral to generate cycle-accurate, jitter-free PWM signals for precise servo positioning, display backlight modulation, and custom tone/audio synthesis.
• Universal I2C Sensor Integration: Apps can communicate over standard I2C buses with external hardware modules, including the MPU6050 accelerometer/gyroscope, BME280 weather sensors, secondary OLED mini-displays, and other common peripherals.

🔔 Floating System Notifications & Inter-App Communication

Currently, apps lack an OS-level way to surface events without directly redrawing the screen.

In v2.0.0, we are introducing a centralized Floating Notification System:

• Running JavaScript apps can dispatch messages to a global OS notification queue.
• The desktop shell displays a floating toast/banner over the active screen buffer, matching the polish of modern mobile operating systems.
• Apps can also pass contextual launch parameters and trigger companion utilities through standardized inter-app messaging.

🧠 Hardware Evolution: Transitioning to the ESP32-S3 (N16R8)

RAM Constraints on the Base ESP32

In v1.0.0, our reference hardware was the standard esp32doit-devkit-v1 (ESP-WROOM-32 with internal SRAM only).

Enabling full Wi-Fi and TCP/IP networking consumes between 50 KB and 100 KB of RAM. Because the base ESP32 provides roughly 192 KB of usable internal RAM, running the network stack, graphics compositor, and Duktape interpreter simultaneously leaves negligible heap for user applications. While the OS will boot on standard non-PSRAM chips with Wi-Fi enabled, app stability depends entirely on the script's memory footprint.

The New Standard

To ensure long-term stability and expandability, the default hardware target for KryonOS is moving to the ESP32-S3 (specifically the N16R8 variant):

• 16 MB Flash & 8 MB Octal PSRAM
• Ample memory headroom for complex user interfaces, asset loading, and background tasks without out-of-memory crashes.

🔄 Partition Limits & True Over-The-Air (OTA) Updates

Why v1.0.0 Uses an Update Notifier

In v1.0.0, the system notifies you when updates are available on GitHub, but cannot flash them automatically due to standard 4 MB flash partition constraints:

• ota_0 app partition: 1,280 KB (1.25 MB)
• ota_1 app partition: 1,280 KB (1.25 MB)
• spiffs storage partition: 1,408 KB (1.37 MB)
• System tables (nvs, otadata): ~32 KB

Because KryonOS bundles a graphical desktop shell, full Duktape interpreter, and UI assets, the compiled OS binary exceeds the 1.25 MB limit required for dual OTA slots on 4 MB boards.

Seamless Background OTA in v2.0.0

With our pivot toward larger flash targets like the N16R8 (16 MB), KryonOS v2.0.0 introduces true background Over-The-Air (OTA) firmware updating, allowing devices to download, verify, and apply full OS updates over Wi-Fi without manual tethering.

📦 Backward Compatibility

• Apps developed for v1.0.0: Fully compatible with KryonOS v2.0.0.
• Apps developed for v2.0.0: Designed for the new v2.0.0 runtime and hardware features, and will not run on legacy v1.0.0 builds.
