Show HN: TinyOS – A minimalist RTOS for Cortex-M written in C
Summary
TinyOS is an ultra-lightweight RTOS intended for Cortex-M devices with a kernel footprint under 10 KB and a 2 KB minimum RAM. It provides preemptive scheduling, synchronization primitives, a shell, a lightweight filesystem, and a built-in network stack with TLS/DTLS, MQTT, CoAP, and OTA capabilities. The repo includes extensive architecture, configuration options, and example projects, making it relevant for small-to-medium business IoT edge deployments and secure device automation.
