This file is a redefinition of all the configuration macro constants that are defined in config.h.in. All the macro constants are defined here as if they were true C extern symbols. The reason for that is that most static code analysis tools operate on preprocessed files. By using this file instead of the final config.h, we simulate the fact that these configuration constants can take any value. So static analysizers don't complain/exclude/assume some parts of source code.

Warning

Some of these definitions can cause problems as there are some places in the code where a true constant is expected. e.g when initializing fields of a constant struct. In these case, static analyzers can complain.

Definition in file config_static_analysis.h.

Variable Documentation

LZ_CONFIG_ON_PANIC_INFINITE_LOOP

const bool LZ_CONFIG_ON_PANIC_INFINITE_LOOP

When 1, run an infinite loop on kernel panic.

When 0, doesn't apply.

LZ_CONFIG_ON_PANIC_SOFTWARE_RESET

const bool LZ_CONFIG_ON_PANIC_SOFTWARE_RESET

When 1, perform a software reset on kernel panic.

When 0, doesn't apply.

LZ_CONFIG_CHECK_NULL_PARAMETERS_IN_LISTS

const bool LZ_CONFIG_CHECK_NULL_PARAMETERS_IN_LISTS

When 1, always check for NULL functions parameters in linked lists implementation.

When 0, never check for NULL parameters.

This is a way to obtain better performances, but it's also less safe.

LZ_CONFIG_CHECK_INTERRUPT_CODE_OVER_LAST_ENTRY

const bool LZ_CONFIG_CHECK_INTERRUPT_CODE_OVER_LAST_ENTRY

When 1, check if the interrupt code sent by the ASM interrupt handler to the base scheduler interrupt handler is an admissible value.

When 0, don't check.

LZ_CONFIG_ON_IDLE_SLEEP

const bool LZ_CONFIG_ON_IDLE_SLEEP

When 1, put the CPU to sleep when it's idle.

When 0, the CPU will actively infinite loop when it's idle.

LZ_CONFIG_IDLE_TASK_HAS_NAME

const bool LZ_CONFIG_IDLE_TASK_HAS_NAME

Configure if the idle task must have a name.

If set to 1, the idle task will have a name attached to it, and the necessary bytes will be used to store this name in read-only data section. This name is defined in this configuration file.

If set to 0, the idle task will have no name attached to it. Thus it can save a few bytes in the read-only data section.

LZ_CONFIG_IDLE_TASK_NAME

const char* const LZ_CONFIG_IDLE_TASK_NAME

The name of the idle task.

Never used if LZ_CONFIG_IDLE_TASK_HAS_NAME is set to 0.

LZ_CONFIG_CHECK_NULL_PARAMETERS_IN_SPINLOCKS

const bool LZ_CONFIG_CHECK_NULL_PARAMETERS_IN_SPINLOCKS

When 1, always check for NULL functions parameters in spinlocks implementation.

When 0, never check for NULL parameters.

This is a way to obtain better performances, but it's also less safe.

LZ_CONFIG_CHECK_NULL_PARAMETERS_IN_MUTEXES

const bool LZ_CONFIG_CHECK_NULL_PARAMETERS_IN_MUTEXES

When 1, always check for NULL functions parameters in mutexes implementation.

When 0, never check for NULL parameters.

This is a way to obtain better performances, but it's also less safe.

LZ_CONFIG_CHECK_NULL_PARAMETERS_IN_SERIAL

const bool LZ_CONFIG_CHECK_NULL_PARAMETERS_IN_SERIAL

When 1, always check for NULL functions parameters in serial API.

When 0, never check for NULL parameters.

This is one way to obtain better performances, but it's also less safe.

LZ_CONFIG_CHECK_WRONG_ENUM_ENTRIES_IN_SERIAL

const bool LZ_CONFIG_CHECK_WRONG_ENUM_ENTRIES_IN_SERIAL

When 1, check for enum parameters that are over the admissible values defined by the enum.

When 0, never check the value of enum parameters.

This is one way to obtain better performances, but it's also less safe.

LZ_CONFIG_SERIAL_USE_INTERRUPTS

const bool LZ_CONFIG_SERIAL_USE_INTERRUPTS

When 1, serial input and output will use interrupt blocking.

When 0, serial input and output will use active waiting (spin).

LZ_CONFIG_AVR_SLEEP_WITH_IDLE_MODE

const bool LZ_CONFIG_AVR_SLEEP_WITH_IDLE_MODE

Enter "Idle Mode" when sleeping.

This is the default value no sleep mode is selected.
