Zephyr Foundations

Mastering the bedrock of Zephyr is essential for writing efficient, robust, and idiomatic code.

Core Workflows

1. Idiomatic C Patterns

Zephyr uses specific macros to manage memory and hardware-software mapping.

• Reference: zephyr_macros.md
• Key Tools: CONTAINER_OF, BIT(), GENMASK(), ARRAY_SIZE.

2. Real-Time Concurrency

Safe multi-threading and interrupt handling are critical for stability.

• Reference: concurrency.md
• Key Tools: k_mutex, k_sem, k_spinlock, atomic_t, ISR safety rules.
