Detailed Description

Timer unit test declarations for NAVHAL.

This header defines the test cases for verifying Timer peripheral functionality in the NAVHAL hardware abstraction layer. It includes tests for:

• Timer initialization and configuration
• Start/stop control
• Counter operations
• Compare register functionality
• Channel control
• Interrupt handling

Note

Uses Unity test framework for assertions

Tests cover both general-purpose and advanced timers

Function Documentation

test_timer_clear_interrupt_flag_clears_UIF()

void test_timer_clear_interrupt_flag_clears_UIF

(

void

)

Test interrupt flag clearing.

Verifies timer_clear_interrupt_flag() clears the update interrupt flag

Verifies that timer_clear_interrupt_flag() clears the Update Interrupt Flag (UIF) in the SR register

test_timer_enable_and_disable_channel()

void test_timer_enable_and_disable_channel

(

void

)

Test channel enable/disable.

Verifies timer_enable_channel() and timer_disable_channel() functions

Verifies:

1. timer_disable_channel() clears the channel enable bit in CCER register
2. timer_enable_channel() sets the channel enable bit in CCER register

test_timer_enable_and_disable_interrupt()

void test_timer_enable_and_disable_interrupt

(

void

)

Test interrupt control.

Verifies timer interrupt enable/disable functionality

Note

May affect other tests if interrupts are globally enabled

Test interrupt control.

Verifies that timer_enable_interrupt() sets the Update Interrupt Enable (UIE) bit in the DIER register

test_timer_get_arr_returns_arr_value()

void test_timer_get_arr_returns_arr_value

(

void

)

Test auto-reload register access.

Verifies timer_get_arr() returns the correct auto-reload value

Verifies that timer_get_arr() correctly returns the value from the ARR register

test_timer_get_count_returns_count_value()

void test_timer_get_count_returns_count_value

(

void

)

Test counter value access.

Verifies timer_get_count() returns the current counter value

Verifies that timer_get_count() correctly returns the current counter value from the CNT register

test_timer_init_sets_prescaler_and_arr()

void test_timer_init_sets_prescaler_and_arr

(

void

)

Test timer initialization.

Verifies timer_init() correctly sets prescaler and auto-reload values

Verifies that timer_init() correctly sets:

1. The prescaler value in PSC register
2. The auto-reload value in ARR register

test_timer_reset_clears_count()

void test_timer_reset_clears_count

(

void

)

Test timer counter reset.

Verifies timer_reset() clears the counter value to zero

Verifies that timer_reset() clears the counter value to zero by checking the CNT register

test_timer_set_compare_and_get_compare()

void test_timer_set_compare_and_get_compare

(

void

)

Test compare register operations.

Verifies timer_set_compare() and timer_get_compare() functionality

Verifies:

1. timer_set_compare() correctly sets the compare value in CCR register
2. timer_get_compare() correctly returns the compare value

test_timer_start_sets_CEN_bit()

void test_timer_start_sets_CEN_bit

(

void

)

Test timer start functionality.

Verifies timer_start() properly sets the counter enable (CEN) bit

Verifies that timer_start() sets the Counter ENable (CEN) bit in the CR1 register

test_timer_stop_clears_CEN_bit()

void test_timer_stop_clears_CEN_bit

(

void

)

Test timer stop functionality.

Verifies timer_stop() properly clears the counter enable (CEN) bit

Verifies that timer_stop() clears the Counter ENable (CEN) bit in the CR1 register
