ZenOS v1.0.0 — First Stable Release

⚡ ZenOS v1.0.0 — (Simplicity · Security · Speed)

First stable release of ZenOS, a real-time operating system for ARM Cortex-M
written in C++11.

🎯 What is ZenOS?
ZenOS is a lightweight, deterministic RTOS designed for safety-critical embedded
systems. Zero heap allocation, O(1) scheduler, and compile-time IEC compliance.

✨ Highlights

• O(1) priority-bitmap scheduler — always deterministic
• 100μs tick resolution (10× finer than FreeRTOS)
• IPC primitives: events, mutexes, queues, semaphores with priority ceiling
• Full C++11 RAII support — zero runtime overhead
• No heap, no hidden allocations

🛡️ Safety Features (all enabled by default)

• Stack canary + SP bounds checking
• TCB integrity validation
• Deadline monitoring
• Hardware & software watchdog
• Background RAM test (March C-)
• Flash CRC verification
• Per-task MPU protection

🏥 Standards Compliance

• IEC 62304 — compile-time enforcement for medical devices
• IEC 61508 — compile-time enforcement for industrial systems

🖥️ Supported Hardware

• STM32F1 (M3), STM32F2 (M3), STM32F4 (M4), STM32F7 (M7), STM32H7 (M7+M4)
• STM32G0 (M0+), STM32G4 (M4), STM32L0 (M0+), STM32L4 (M4), STM32WB (M4)

🧪 Tested on real hardware (STM32F103C8T6) with 22+ test suites

📖 Full API tutorial, safety manual, and Persian documentation included.
