C++ Sender Patterns to Wrangle C++ Concurrency in Embedded Devices
Talkat CppCon 2024 · on Thursday, 2024-09-19· at 14:00· Spruce 3/4, 6700 North Gaylord Rockies Boulevard·
summary
Claims that senders tame bare‑metal concurrency by composing Intel's open source bare-metal senders and receivers into reusable building blocks, avoiding exceptions and dynamic allocators, and yielding explicit timeout adapter and fixed‑priority / trigger scheduler patterns. Shows a working STM32 robot demo that serializes interrupt-driven peripherals and a GDB + Python tool that graphs sender chains so debugging reveals which link handled a signal rather than guessing.
