/**
|
|
* @brief Assertion handling.
|
|
*
|
|
* Define **STA_ASSERT_ENABLE** in `<sta/config.hpp>` to enable module.
|
|
*
|
|
* When **DEBUG** is defined the module will be enabled automatically.
|
|
* Defining **NDEBUG** or **STA_ASSERT_DISABLE** always overrides enabling the module.
|
|
*
|
|
* Both `assert_failed` and `assert_halt` provide weak definitions and
|
|
* can be overridden by the application. `assert_halt` is only called
|
|
* via the STA_HALT macro which can also be provided by the application.
|
|
*
|
|
* The default implementation of `assert_failed` uses **STA_DEBUG_PRINT** internally
|
|
* and will not generate any output if `<sta/debug_serial.hpp> is disabled.
