SHIT Here we go again

🚀 AkiraOS v1.2.3-oni — New Release!

Dropped a new update for AkiraOS — v1.2.3-oni.
Small step in number — big step for the whole platform.

More stable, cleaner, faster to build, and closer to what I always wanted AkiraOS to be:
a pocket-sized dev tool, retro console, and open playground built on Zephyr + WASM.

Clone it, build it, hack with it:

AkiraOS keeps growing. Stay tuned — more crazy stuff soon.

New revisions of AkiraConsole (V3) and AkiraMicro (V1.5)

🎉 AkiraConsole V3 is now OSHWA Certified!

AkiraConsole V3 has officially received Open Source Hardware Association (OSHWA) certification.

UID: MD000003
Certificate: https://certification.oshwa.org/md000003.html

This confirms that the project meets OSHWA’s open-source hardware definition and is fully documented and shareable. Thanks to everyone who supported, tested, and contributed—more updates coming soon!

Building WebAssembly Apps for Akira Console

WebAssembly for applications, giving you security, portability, and ease of development all in one.

Why WASM on Akira?
- Secure: Sandboxed apps with capability-based permissions
- Portable: Build once, run on ESP32, nRF5x, or STM32
- Fast: Near-native performance
- Simple: No linking hassles, just compile and deploy

Prerequisites

- WASI SDK — Download from https://github.com/WebAssembly/wasi-sdk/releases and extract to /opt/wasi-sdk
- AkiraSDK — Located in AkiraSDK/ folder (header-only, no extra linking needed)
- Basic C/C++ knowledge — That's it!

5-Minute Quick Start

# Install WASI SDK
wget https://github.com/WebAssembly/wasi-sdk/releases/download/wasi-sdk-21.0/wasi-sdk-21.0-linux.tar.gz
tar xzf wasi-sdk-21.0-linux.tar.gz && sudo mv wasi-sdk-21.0 /opt/wasi-sdk

# Build your first app
cd AkiraSDK/wasm_apps/hello_world
../../build_wasm_app.sh -o hello_world.wasm main.c

Done! Your hello_world.wasm is ready to run.

Build: ../../build_wasm_app.sh -o my_game.wasm main.c

Memory Tips

- ESP32-S3 has ~520KB RAM — keep it lean!
- Use stack variables when possible
- Avoid large static buffers: static uint8_t buf[256]; not [100000]
- No deep recursion (stack overflow risk)

Debugging & Troubleshooting

Debug with printf: Output appears in the console when running on native_sim or connected hardware.

Example Apps in AkiraSDK

Explore these in AkiraSDK/wasm_apps/:
- hello_world — Minimal example
- sensor_demo — Read sensors
- display_graphics — Graphics rendering
- gui_demo — UI elements
- hid_keyboard_demo — Input handling
- blink_led — LED control
- logic_analyzer — Data capture

Best Practices

1. Check return values — Handle errors gracefully
2. Graceful fallback — Not all capabilities are always available
3. Power efficiency — Sleep when idle to save battery
4. Smooth frame rate — Target 30+ FPS for responsive feel
5. Use stack memory — Faster than heap allocation

Next Steps

1. Clone the repository and explore sample apps
2. Build hello_world or sensor_demo
3. Modify and add your logic
4. Deploy to hardware
5. Share with the community!
