TIM_PrescalerConfig

Example:

This example illustrates how to configure the TIM3 prescaler.

{

...

TIM_PrescalerConfig (TIM3, 0x5);

...

}

TIM_PrescalerValue

Example:

This example illustrates how to get the TIM2 prescaler value.

{

vu8 bCurrentPrescaler;

...

bCurrentPrescaler = TIM_PrescalerConfig (TIM2);

...

}

Function Name

Function Prototype

void TIM_PrescalerConfig (TIM_TypeDef *TIMx, u8

Xprescaler);

Behavior Description

This routine configures the TIM prescaler value to divide the internal

clock.

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

Xprescaler: specifies the TIM prescaler value (8bit).

Output Parameter

None

Return Value

None

Required preconditions

None

Called Functions

None

Function Name

TIM_PrescalerValue

Function Prototype

u8 TIM_PrescalerValue (TIM_TypeDef *TIMx);

Behavior Description

This routine gets the TIM prescaler value when the internal clock is

used.

Input Parameter

TIMx: specifies the timer to get its prescaler value. Refer to TIM values

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

Output Parameter

None

Return Value

The Current TIM prescaler Value (8bit).

Required preconditions

None

Called Functions

None
