Neon RTOS
Neon RTOS is a lightweight real-time operating system that supports multiple architectures, currently including ARM Cortex-M and RISC-V.
Features
- Lightweight real-time operating system kernel
- Multi-task scheduling
- Inter-task communication (signals, mutexes)
- Memory management
- Interrupt handling
- Multi-architecture support (ARM Cortex-M3, RISC-V)
- Integrated development environment support (VSCode debugging)
Quick Start
Requirements
- Rust toolchain (nightly)
- ARM GCC toolchain (for Cortex-M) or RISC-V GCC (for RISC-V)
- VSCode + Cortex-Debug extension (for debugging)
- QEMU (for emulation)
Building and Running
Option 1: Command Line Build
# Navigate to example directory
cd examples/basic
# Build for Cortex-M
cargo build --target thumbv7m-none-eabi
# Or build for RISC-V
cargo build --target riscv32imac-unknown-none-elf
Option 2: VSCode Debugging
- Open VSCode
- Load the project root directory
- Press F5 to start debugging (launch.json is pre-configured)
