Public initialization functions for shared dependencies.

Function Documentation

init_log()

ERR_te init_log

(

void

)

Initializes the logging subsystem.

Configures the log module with a fixed hardware target: USART1 at 115200 baud on GPIOA pin 9 (alternate function AF7).

Returns

• ERR_OK on success
• Propagated error from log_init on failure

init_log

    ERR_te err;

    log_handle.usart_baud_rate = USART_BAUD_RATE_115200;
    log_handle.gpio_port = GPIOA;
    log_handle.gpio_pin = GPIO_PIN_9;
    log_handle.gpio_alternate_function = GPIO_ALTERNATE_FUNCTION_AF7;
    err = log_init(&log_handle);
 
    return err;

init_systick()

ERR_te init_systick

(

void

)

Initializes the SysTick timer.

Configures SysTick to use the processor clock source with interrupt generation enabled, providing the system millisecond tick used by systick_get_ms.

Returns

• ERR_OK on success
• Propagated error from systick_init on failure

init_systick

init_neo6()

ERR_te init_neo6

(

void

)

Initializes the NEO-6 GPS module.

Initializes the NEO-6 subsystem and registers a handle configured for USART6 at 9600 baud, with RX on GPIOA pin 12 and TX on GPIOA pin 11 (alternate function AF8). Starts the subsystem after handle initialization.

Returns

• ERR_OK on success
• Propagated error from the last failing NEO-6 call on failure

Note

Errors from intermediate steps (subsys init, handle init) are overwritten by subsequent calls. Only the last error is returned.

init_rtc()

ERR_te init_rtc

(

void

)

Initializes the RTC peripheral and sets a default calendar and time.

Initializes the RTC hardware. If the RTC is already initialized (ERR_MODULE_ALREADY_INITIALIZED), the function returns immediately without overwriting the current time, preserving any previously set value.

If initialization succeeds, sets the calendar to Thursday, 29 January 2026 and the time to 00:00:00 as a compile-time default.

Returns

• ERR_OK on success
• ERR_MODULE_ALREADY_INITIALIZED if the RTC was already initialized
• Propagated error from rtc_init on failure
