serial wire viewer

Serial Wire Viewer (SWV) is a feature of the ARM Cortex-M microcontroller that allows real-time tracing and debugging of embedded systems. It enables developers to visualize the system behavior at runtime, analyze code execution, and detect errors and performance issues.

SWV uses the Serial Wire Debug (SWD) interface to capture trace data from the microcontroller and send it to a host computer for analysis. The captured data can include program flow, variable values, and event timestamps, among others.

The SWV feature provides a powerful tool for developers to optimize their code and improve system performance. It can help identify bottlenecks, optimize algorithms, and debug complex issues that may be difficult to reproduce or diagnose using traditional debugging techniques.

Overall, SWV is a valuable addition to the ARM Cortex-M microcontroller, providing developers with a powerful tool for debugging and optimizing their embedded systems.
