RTIC is a hardware-accelerated concurrency framework for building real-time systems on ARM Cortex-M and most RISC-V microcontrollers in Rust. It provides event- and software-triggered tasks, message passing, a timer queue, and compile-time-guaranteed deadlock-free, data-race-free resource sharing with minimal scheduling overhead.

Use cases

• build a real-time embedded application in Rust on a Cortex-M microcontroller
• implement periodic tasks with a timer queue on bare-metal hardware
• share data between interrupt handlers without data races
• schedule preemptive priority-based tasks with no dynamic allocation
• replace an RTOS with a lightweight no-std task scheduler
• run WCET-analyzable task scheduling on embedded firmware

When to choose

• you are writing no-std Rust firmware for ARM Cortex-M or supported RISC-V devices
• you need compile-time guarantees against deadlocks and data races
• you want minimal scheduling overhead by leveraging hardware interrupts
• you need a single-stack, allocator-free concurrency model

When to avoid

• you target non-embedded platforms like Linux or Windows
• you need full RTOS features such as filesystems or networking stacks
• your MCU architecture is not Cortex-M or a supported RISC-V backend
• you prefer async executors like Embassy with async peripheral drivers
