Serial communication between microcontrollers is often required in complex embedded systems, yet poorly designed protocols can lead to subtle bugs and unreliable behavior.

In this session, I will share a structured approach to build a robust serial communication framework. We will cover several key design pillars:

• Defining structured and extensible message types
• Implementing rigorous sanity checks and error detection (CRCs, checksums)
• Handling retries and timeout logic for dropped packets
• Managing message prioritization to ensure critical data arrives first

Attendees will gain actionable insights and a practical approach to building scalable, modular serial communication protocols that minimize future pitfalls and simplify system debugging.
