TIM_OPModeConfig

Example:

This example illustrates how to configure the TIM3 one pulse mode to generate an external

wave with a pulse length of 0xABC in terms of timer period. The pulse generation is

activated by a rising edge on the input capture A pin.

...

TIM_OPModeConfig (TIM3, 0xABC, TIM_HIGH, TIM_LOW, TIM_RISING);

Function Name

TIM_OPModeConfig

Function Prototype

void TIM_OPModeConfig (TIM_TypeDef *TIMx,

u16 XpulseLength,

TIM_Logic_Levels XLevel1,

TIM_Logic_Levels XLevel2,

TIM_Clock_Edges Xedge);

Behavior Description

This routine is used to configure the one pulse mode.

Input Parameter 1

TIMx specifies the TIM to be configured. Refer to TIM values on

page 103 for more details on the allowed values of this parameter.

Input Parameter 2

XpulseLength: specifies the pulse length.

Input Parameter 3

XLevel1: specifies the output level on the OCMPA pin during the pulse.

Refer to Logic levels enumeration on page 105 for more details on the

allowed values of this parameter.

Input Parameter 4

XLevel2: specifies the output level on the OCMPB pin after the pulse.

Refer to Logic levels enumeration on page 105 for more details on the

allowed values of this parameter.

Input Parameter 5

Xedge: specifies the edge to be detected by the input capture A pin.

Refer to Clock edges enumeration on page 104 for more details on the

allowed values of this parameter.

– TIM_RISING: a rising edge will activate the one pulse mode

– TIM_FALLING: a falling edge will activate the one pulse mode

Output Parameter
