// Safe multi-line macro using do-while(0) block
// Protects against syntax errors when used in if-else statements without braces

📖 C/C++ Code Generators

Tools to facilitate writing tedious boilerplate code while maintaining the highest standards of software engineering and MISRA C.

Multi-line Macros: Always use the do { ... } while(0). It protects against undefined preprocessor behavior when the macro is used e.g. after a bare if() statement without braces. It also prevents dangling semicolon issues.
Bitmasks in Enums: A much more readable solution for managing multiple flags in a single register config variable. Guarantees bit uniqueness.
LUT Arrays (Look-Up Table): Relieve the processor from calculating heavy math (e.g. Trigonometry) in real-time. Ideal for waveform generation in DAC!
