Detailed Description

Internal state of the SysTick driver.

Internal state of the SSD1309 subsystem.

Internal state of the SD card subsystem.

Internal state of the NEO-6 subsystem.

Internal state of the menu subsystem.

Internal state of the log subsystem.

Internal state of the IO subsystem.

Internal state of the data log subsystem.

Internal state of the console subsystem.

Internal state of the command subsystem.

Internal state of the button subsystem.

Holds the millisecond counter incremented by SysTick_Handler and an initialization guard to prevent double-initialization.

Holds the pool of button handles, the count of registered buttons, and the subsystem lifecycle flags (initialized / started).

Accessed only through the module's public API.

Holds the registered client table and the subsystem's own log level. Statically initialized at startup; no explicit init function is required.

Holds the two circular buffers, a pointer to the active USART instance, and the current console mode flag. Statically initialized at startup.

Holds the pool of log handles, the count of active handles, and the subsystem lifecycle flags.

Holds the pool of IO handles, the count of active handles, and the subsystem lifecycle flags.

Holds the active USART instance, the force-disable flag used by the console module during interactive input, and an initialization guard.

Holds the pool of menu handles, the count of active handles, and the subsystem lifecycle flags.

Holds the single hardware handle, both circular buffers, the parsed GPS info structure, and the subsystem lifecycle flags.

Holds the pool of SD card handles, the count of active handles, and the subsystem lifecycle flags.

Holds the single hardware handle, the display framebuffer, and the subsystem lifecycle flags.
