LL_LPTIM_Init() function
Configure the LPTIMx peripheral according to the specified parameters.
Syntax
Implemented in ![]()
stm32f4xx_ll_lptim.c:140
Arguments
Argument
Description
LPTIMx
LP Timer Instance
LPTIM_InitStruct
pointer to a ![]()
LL_LPTIM_InitTypeDef
structure
Return value
An ErrorStatus enumeration value: - SUCCESS: LPTIMx instance has been initialized - ERROR: LPTIMx instance hasn't been initialized
Notes
LL_LPTIM_Init can only be called when the LPTIM instance is disabled. LPTIMx can be disabled using unitary function LL_LPTIM_Disable().
