A critical design risk where a low-priority task holds a resource needed by a high-priority task. Solving this requires protocols like Priority Inheritance . 2. Engineering Practices for Robust Systems
Since you cannot compile code on a small microcontroller, you use a cross-compiler (like arm-none-eabi-gcc ) on your PC to generate a binary or hex file. Debugging and Simulation A critical design risk where a low-priority task
Link your PC to the target board via a JTAG/SWD interface. Engineering Practices for Robust Systems Since you cannot
A fail-safe mechanism where the software must "kick the dog" (reset a timer) at regular intervals. If the software freezes due to a bug or EMI, the timer expires and forces a hardware reset. 3. Developing and "Installing" the System If the software freezes due to a bug
The ability of a higher-priority task to interrupt a lower-priority one immediately.
Unlike general-purpose computing (like a PC), where the goal is high average throughput, RTES prioritizes . A deterministic system guarantees a specific response time (latency) for every event, regardless of the system load. Hard vs. Soft Real-Time
This guide explores the foundational principles and modern engineering practices for real-time embedded systems (RTES). 1. Core Principles of Real-Time Design
