Macros
#define	assert_na(expression)
	The assert_na() macro tests the given expression, like standard assert macro with __ASSERT_USE_STDERR definition, but don't call abort().

#define	ASSERT_USE_ABORT
	Replaces the behavior of the ASSERT macro with the standard one.

#define	ASSERT(expression)
	The macro tests the given expression.

Detailed Description

Alternative AVR assert.

Author: Simon Litt simon.nosp@m.@1it.nosp@m.t.net https://coding.1itt.net, https://github.com/SimonLitt

Because standard __assert calls abort() function.

#include <sls-avr/assert.h>
int main(void) {
    ...
    assert_na(PIND == 0xF0);
    ...
}

#define ASSERT_USE_ABORT
#include <sls-avr/assert.h>
int main(void) {
    ...
    ASSERT(PIND == 0xF0);
    ...
}

Macro Definition Documentation

#define ASSERT ( expression )

The macro tests the given expression.

Depending on the ASSERT_USE_ABORT macro, it calls standard assert() or assert_na()

Parameters

expression Expression to test for.

See also: ASSERT_USE_ABORT; assert_na; https://www.nongnu.org/avr-libc/user-manual/group__avr__assert.html

#define assert_na ( expression )

Value:

((expression) ? (void)0 : \

fprintf(stderr, "Assertion failed: (%s), function %s, file %s, line %u.\n", #expression, __func__ , __FILE__, __LINE__))

The assert_na() macro tests the given expression, like standard assert macro with __ASSERT_USE_STDERR definition, but don't call abort().

The macro may be removed at compile time by defining NDEBUG as a macro (e.g., by using the compiler option -DNDEBUG).

Parameters

expression Expression to test for.

#define ASSERT_USE_ABORT

Replaces the behavior of the ASSERT macro with the standard one.

Attention: If the macro is defined, it also defines the __ASSERT_USE_STDERR macro. *
