static void cleanup_extint_callback_mode_test ( const struct test_case test)
static

Cleanup function for callback mode test.

This function disables the callback & external interrupt channel.

Parameters
testCurrent test case.

static void cleanup_extint_polled_mode_test ( const struct test_case test)

Cleanup function for polled mode test.

This function disables the external interrupt channel.

Parameters
testCurrent test case.

static void extint_user_callback ( void  )
static

External interrupt callback function.

Called by external interrupt driver on interrupt detection.

int main ( void  )
static void run_extint_callback_mode_test ( const struct test_case test)
static

Test for external interrupt detection using callback.

This test changes the logic level of PB05 from high to low so that the external interrupt channel detects the edge and calls the callback function.

Detection is tested for both rising and falling edges.

Parameters
testCurrent test case.

static void run_extint_polled_mode_test ( const struct test_case test)
static

Test for external interrupt detection by polling.

This test changes the logic level of PB05 from high to low so that the external interrupt channel detects the edge.

Detection is tested for both rising and falling edges.

Parameters
testCurrent test case.
