Core Concepts

Core (C89)

The core provides:

fixed-size integer types
result codes
logging callback
initialization state

It contains no platform-specific code and no standard library dependencies.

Drivers

Drivers are defined by a name and an initialization function. They are stored in a static registry and initialized in order.

Modules

Modules follow the same structure as drivers and are initialized after them.

Utilities

mck includes:

memory utilities (set, copy, arena allocator)
static lists
string utilities
math helpers
bitsets
ring buffers
hash tables
event queues

These components are designed for environments without dynamic allocation.

Time System

A minimal time system provides:

tick counter
millisecond uptime
second uptime

It is hardware-agnostic and can be driven by any timer interrupt.
