RNode on OS3: a Minimal Reticulum Firmware for the CH32V003

RNode on OS3: a Minimal Reticulum Firmware for the CH32V003 I wanted to know how small a useful Reticulum transport could get. Not a mock-up. Not a “Hello World over LoRa”. Not a proof of concept that only works in a lab once. A real firmware image that can be flashed onto a cheap microcontroller board, detected by rnsd, and used with tools like Sideband and NomadNet. This release is the result: a small RNode-compatible firmware image based on OS3, targeting the CH32V003 and an E22-900M22S LoRa module built around the SX1262. ...

OS3: Architecture of a Deterministic Event-Driven Microkernel

OS3: Architecture of a Deterministic Event-Driven Microkernel The Starting Point Most embedded projects inherit a mental model from desktop operating systems: threads, a scheduler, background tasks, preemption. These abstractions exist for good reasons in general-purpose computing. In deeply embedded systems, they introduce a specific problem: when something goes wrong, you cannot easily answer the question why did this happen now? OS3 starts from a different premise. The kernel has one purpose: preserve causal integrity in time. Every behavior must be traceable to an explicit cause. Latency is a signal. Ambiguity in the execution model is a defect, not a feature. ...
