LL_LPTIM_SetPrescaler() function

Set actual prescaler division ratio.

Syntax

from stm32f4xx_ll_lptim.h:614

__STATIC_INLINE void LL_LPTIM_SetPrescaler(LPTIM_TypeDef *LPTIMx, uint32_t Prescaler);

Arguments

LPTIMx

Low-Power Timer instance

Prescaler

This parameter can be one of the following values: @arg LL_LPTIM_PRESCALER_DIV1 @arg LL_LPTIM_PRESCALER_DIV2 @arg LL_LPTIM_PRESCALER_DIV4 @arg LL_LPTIM_PRESCALER_DIV8 @arg LL_LPTIM_PRESCALER_DIV16 @arg LL_LPTIM_PRESCALER_DIV32 @arg LL_LPTIM_PRESCALER_DIV64 @arg LL_LPTIM_PRESCALER_DIV128

Return value

None

Notes

This function must be called when the LPTIM instance is disabled. When the LPTIM is configured to be clocked by an internal clock source and the LPTIM counter is configured to be updated by active edges detected on the LPTIM external Input1, the internal clock provided to the LPTIM must be not be prescaled.
