achieve the required counter clock frequency.
Parameters:
__TIMCLK__: timer input clock frequency (in Hz)
__CNTCLK__: counter clock frequency (in Hz)
Return value:
Prescaler: value (between Min_Data=0 and
Max_Data=65535)
Notes:
ex: __LL_TIM_CALC_PSC (80000000, 1000000);
__LL_TIM_CALC_ARR
Description:
HELPER macro calculating the auto-reload value
to achieve the required output signal frequency.
Parameters:
__TIMCLK__: timer input clock frequency (in Hz)
__PSC__: prescaler
__FREQ__: output signal frequency (in Hz)
Return value:
Auto-reload: value (between Min_Data=0 and
Max_Data=65535)
Notes:
ex: __LL_TIM_CALC_ARR (1000000,
LL_TIM_GetPrescaler (), 10000);
__LL_TIM_CALC_DELAY
Description:
HELPER macro calculating the compare value
required to achieve the required timer output
compare active/inactive delay.
Parameters:
__TIMCLK__: timer input clock frequency (in Hz)
__PSC__: prescaler
__DELAY__: timer output compare active/inactive
delay (in us)
Return value:
Compare: value (between Min_Data=0 and
Max_Data=65535)
Notes:
ex: __LL_TIM_CALC_DELAY (1000000,
LL_TIM_GetPrescaler (), 10);
__LL_TIM_CALC_PULSE
Description:
HELPER macro calculating the auto-reload value
to achieve the required pulse duration (when the
timer operates in one pulse mode).
