函数说明

SysTick_CLKSourceConfig()

void SysTick_CLKSourceConfig

(

uint32_t

SysTick_CLKSource

)

Configures the SysTick clock source.

参数

SysTick_CLKSource

specifies the SysTick clock source. This parameter can be one of the following values: SysTick_CLKSource_HCLK_Div4: AHB clock divided by 4 selected as SysTick clock source. SysTick_CLKSource_HCLK: AHB clock selected as SysTick clock source.

返回值

None

SysTick_DelayMs()

void SysTick_DelayMs

(

uint32_t

Ms

)

Delay n Ms.

参数

Ms	Number of Ms to delay.

注解

None

返回值

None

SysTick_DelayNticks()

void SysTick_DelayNticks

(

uint32_t

Ticks

)

Delay n ticks.

参数

Ticks

Number of ticks to delay.

注解

Since SysTick_LOAD is a 24-bit register, the n_ticks must be less than 16777216.

返回值

None

SysTick_DelayUs()

void SysTick_DelayUs

(

uint32_t

Us

)

Delay n Us.

参数

Us	Number of Us to delay.

注解

None

返回值

None
