Printf-based Debugging

Overview

Primary reliance on printf statements for debugging embedded software instead of using proper debugging tools, logging frameworks, or debug interfaces.

Benefits

• Simple to implement
• Works on any platform
• No additional tools required
• Easy to understand output

Limitations & Risks

• Clutters code with debug statements
• Poor performance impact
• Difficult to control debug levels
• Not suitable for real-time systems

Recommended Actions

Migrate to structured logging frameworks and proper debugging tools with SWD/JTAG support

Additional Notes

Still useful for quick debugging but should not be the primary debugging strategy
