timer0_mode0_delay_ms

#define timer0_mode0_delay_ms

(

ms

)

Value:

do                                                      \
{                                                       \
    uint16_t ticks = timer0_mode0_ms_to_ticks(ms);      \
    timer0_mode0_delay(ticks);                          \
} while(0);

Run timer0 mode0 once and wait with program flow blocking timer not finished.

Parameters

ms	uint16_t delay ms duration

timer0_mode0_Hz_to_ticks

#define timer0_mode0_Hz_to_ticks

(

frequency

)

(timer_Hz_to_ticks(frequency, get_timer0_clock_divider(), get_frequency_divider_scale()))

Converts frequency to timer0 mode0 ticks.

Call this method after timer0 is initialized and MCU clock frequency divider scale is set.

Warning

On uint16_t overflow this routine returns 0.

Parameters

frequency

3uint32_t frequency value in Hz. Should not be 0;1

Returns

uint16_t timer0 ticks corresponding to frequency value or 0 on uint16_t overflow

timer0_mode0_ms_to_ticks

#define timer0_mode0_ms_to_ticks

(

ms

)

(timer_ms_to_ticks(ms, get_timer0_clock_divider(), get_frequency_divider_scale()))

Convert milliseconds to timer0 ticks.

Parameters

ms	uint16_t ms to convert. Range is 1..~9000

Returns

uint16_t Number of timer ticks corresponding to the input time. Returns 0 if the result overflows uint16_t range.

timer0_mode0_start_Hz

#define timer0_mode0_start_Hz

(

freq

)

Value:

do                                                      \
{                                                       \
    uint16_t ticks = timer0_mode0_Hz_to_ticks(freq);    \
    timer0_mode0_start(ticks);                          \
} while (0);

Start timer0 in mode 0 with Hz frequency.

Parameters

freq	uint32_t timer overflow frequency in Hz

timer0_mode0_start_ms

#define timer0_mode0_start_ms

(

ms

)

Value:

do                                                      \
{                                                       \
    uint16_t ticks = timer0_mode0_ms_to_ticks(ms);      \
    timer0_mode0_start(ticks);                          \
} while (0);

Start timer0 in mode 0 with ms duration.

Parameters

ms	uint16_t timer overflow duration

timer0_mode0_ticks_to_Hz

#define timer0_mode0_ticks_to_Hz

(

ticks

)

(timer_ticks_to_Hz(ticks, get_timer0_clock_divider(), get_frequency_divider_scale()))

Converts ticks to timer frequency for timer0 multiplied by 100.

The output frequency = (SYSclk/timer_clock_divider)/(1 + ticks).

Call this method after timer0 is initialized and MCU clock frequency divider scale is set.

uint16 ticks used in timer mode 0, 1, 3. For timer mode2 (8 bit autoreladable timer) ticks can be in 0..255 range.

Parameters

ticks

uint16_t timer ticks count to covert

Returns

uint32_t timer overflow frequency corresponding to given ticks count

timer0_mode0_ticks_to_ms

#define timer0_mode0_ticks_to_ms

(

ticks

)

(timer_16bit_ticks_to_ms(ticks, get_timer0_clock_divider(), get_frequency_divider_scale()))

Convert ticks count to ms.

Parameters

ticks

uint16_t ticks count. Range 7...65535

Returns

milliseconds time corresponing to timer ticks. Range 0..9043
