Both sta::assert_failed and sta::assert_halt provide weak definitions and can be overridden by the application. sta::assert_halt is only called via the STA_HALT macro which can also be provided by the application.

The default implementation of sta::assert_failed uses STA_DEBUG_PRINT internally and will not generate any output if the DEBUG_SERIAL module is disabled.

Debug Serial

Debug serial output macros.

Configuration:

#define STA_DEBUG_SERIAL_ENABLE: Enable module
#define STA_DEBUG_SERIAL_DISABLE: Forces module off when defined
DEBUG: Automatically enables module when defined
NDEBUG: Forces module off when defined

The sta::DebugSerial instance must be provided.

Endian

Endian-ness conversion for multi-byte types.

Enum Flags

Type for using enum values as combinable flags.

Lang

Macros related to compiler features. Not actually part of the C/C++ language.

MCU

Defines specific to different MCUs. Include the appropriate header from sta/mcu for the MCU used by the application in the <sta/config.hpp> header.

Printf

Choose which printf implementation is used by STA libraries.

Configuration:

#define STA_PRINTF_USE_STDLIB: Use the stdlib implementation
#define STA_PRINTF_USE_MPALAND: Use the implementation by Marco Paland (thread safe & reentrant)

HAL Delay

HAL based delay functions.

Configuration:

#define STA_HAL_DELAY_ENABLE: Enable module
#define STA_HAL_DELAY_US_TIM <tim_handle>: 1 MHz TIM instance used by sta::delayUs

TIM time base must be started before using sta::delayUs by calling sta::initHAL. When using the startup system task this is handled automatically.
