1 通用定时器（TIM）预览

1.1 函数TIM_DeInit

1.2 TIM_TimeBaseInit

例：
TIM_TimeBaseInitTypeDef TIM_TimeBaseStructure; TIM_TimeBaseStructure.TIM_Period = 0xFFFF; TIM_TimeBaseStructure.TIM_Prescaler = 0xF; TIM_TimeBaseStructure.TIM_ClockDivision = 0x0; TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up; TIM_TimeBaseInit(TIM2, & TIM_TimeBaseStructure);

1.3 TIM_OCInit

例：
/* Configures the TIM2 Channel1 in PWM Mode */ TIM_OCInitTypeDef TIM_OCInitStructure; TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1; TIM_OCInitStructure.TIM_Channel = TIM_Channel_1; TIM_OCInitStructure.TIM_Pulse = 0x3FFF; TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_High; TIM_OCInit(TIM2, & TIM_OCInitStructure);

1.4 TIM_ICInit

例：
/* The following example illustrates how to configure the TIM2 in PWM Input mode : The external signal is connected to TIM2 CH1 pin, the Rising edge is used as active edge, the TIM2 CCR1 is used to compute the frequency value the TIM2 CCR2 is used to compute the duty cycle value */
TIM_DeInit(TIM2);
TIM_ICStructInit(&TIM_ICInitStructure); TIM_ICInitStructure.TIM_ICMode = TIM_ICMode_PWMI; TIM_ICInitStructure.TIM_Channel = TIM_Channel_1; TIM_ICInitStructure.TIM_ICPolarity = TIM_ICPolarity_Rising; TIM_ICInitStructure.TIM_ICSelection = TIM_ICSelection_DirectTI; TIM_ICInitStructure.TIM_ICPrescaler = TIM_ICPSC_DIV1; TIM_ICInitStructure.TIM_ICFilter = 0x0;
TIM_ICInit(TIM2, &TIM_ICInitStructure);

1.5 TIM_TimeBaseStructInit

例：
/* The following example illustrates how to initialize a TIM_BaseInitTypeDef structure */
TIM_TimeBaseInitTypeDef TIM_TimeBaseInitStructure; TIM_TimeBaseStructInit(& TIM_TimeBaseInitStructure);

1.6 TIM_OCStructInit

例：
/* The following example illustrates how to initialize a TIM_OCInitTypeDef structure */
TIM_OCInitTypeDef TIM_OCInitStructure; TIM_OCStructInit(& TIM_OCInitStructure);

1.7 TIM_ICStructInit

1.8 TIM_Cmd

例：/* Enables the TIM2 counter */ TIM_Cmd(TIM2, ENABLE);

1.9 TIM_ITConfig

例：/* Enables the TIM2 Capture Compare channel 1 Interrupt source */ TIM_ITConfig(TIM2, TIM_IT_CC1, ENABLE);

1.10 TIM_DMAConfig

TIM_DMABase 描述

TIM_DMABurstLength 描述

例：/* Configures the TIM2 DMA Interface to transfer 1 byte and to use the CCR1 as base address */ TIM_DMAConfig(TIM2, TIM_DMABase_CCR1, TIM_DMABurstLength_1Byte)

1.11 TIM_DMACmd

1.12 TIM_InternalClockConfig

例：
/* Selects the internal clock for TIM2 */ TIM_InternalClockConfig(TIM2);
