第十六讲：高级控制定时器系统...ppt

21天学嵌入式开发,第十六讲：高级控制定时器系统,课程安排,高级控制定时器（TIM1）结构TIM1寄存器结构高级控制定时器（TIM1）的编程方法,高级控制定时器（TIM1）结构,TIM1由一个16位的自动装载计数器组成，它由一个可编程预分频器驱动。高级控制定时器TIM1和通用控制定时器TIMx是完全独立的。TIM1定时器的主要功能特性。,时基单元,时基单元包含：计数器寄存器(TIM1_CNT)预分频器寄存器(TIM1_PSC)自动装载寄存器(TIM1_ARR)周期计数寄存器(TIM1_RCR),计数器模式,STM32高级控制定时器TIM1的16位计数器可以采用三种方式工作：向上计数模式向下计数模式中央对齐模式(向上/向下计数),向下重复计数器,计数器溢出/下溢时更新事件(UEV)它只能在重复向下计数达到0的时候产生。重复向下计数器在下述任一条件成立时递减：向上计数模式下每次计数器溢出时。向下计数模式下每次计数器下溢时。中央对齐模式下每次溢出和下溢时。,TIM1的特殊工作模式,输入捕获模式PWM输入模式强制输出模式输出比较模式PWM模式单脉冲模式(OPM)编码器接口模式,与霍尔元件的接口,通用定时器和高级控制定时器可以联合使用来实现与霍尔元件的接口。操作步骤,TIM1寄存器结构,typedefstructvu16CR1;/控制寄存器1u16RESERVED0;vu16CR2;/控制寄存器2u16RESERVED1;vu16SMCR;/从模式控制寄存器u16RESERVED2;vu16DIER;/DMA/中断使能寄存器u16RESERVED3;vu16SR;/状态寄存器u16RESERVED4;vu16EGR;/事件产生寄存器u16RESERVED5;vu16CCMR1;/捕获/比较模式寄存器1u16RESERVED6;vu16CCMR2;/捕获/比较模式寄存器2u16RESERVED7;vu16CCER;/捕获/比较使能寄存器u16RESERVED8;vu16CNT;/计数器寄存器u16RESERVED9;vu16PSC;/预分频寄存器u16RESERVED10;vu16ARR;/自动重装载寄存器u16RESERVED11;vu16RCR;/周期计数寄存器u16RESERVED12;vu16CCR1;/捕获/比较寄存器1u16RESERVED13;vu16CCR2;/捕获/比较寄存器2u16RESERVED14;vu16CCR3;/捕获/比较寄存器3u16RESERVED15;vu16CCR4;/捕获/比较寄存器4u16RESERVED16;vu16BDTR;/刹车和死区寄存器u16RESERVED17;vu16DCR;/DMA控制寄存器u16RESERVED18;vu16DMAR;/连续模式的DMA地址寄存器u16RESERVED19;TIM1_TypeDef;,TIM1的编程方法,库函数：TIM1_DeInit函数TIM1_TIM1BaseInit函数TIM1_OC1Init函数TIM1_OC2Init函数TIM1_OC3Init函数TIM1_OC4Init函数TIM1_BDTRConfig函数TIM1_ICInit函数TIM1_PWMIConfig函数TIM1_TIM1BaseStructInit函数TIM1_OCStructInit函数TIM1_ICStructInit函数TIM1_BDTRStructInit函数TIM1_Cmd函数TIM1_CtrlPWMOutputs函数TIM1_ITConfig函数TIM1_DMAConfig函数,TIM1的编程方法(续),库函数：TIM1_DMACmd函数TIM1_InternalClockConfig函数TIM1_ETRClockMode1Config函数TIM1_ETRClockMode2Config函数TIM1_ETRConfig函数TIM1_ITRxExternalClockConfig函数TIM1_TIxExternalClockConfig函数TIM1_SelectInputTrigger函数TIM1_UpdateDisableConfig函数TIM1_UpdateRequestConfig函数TIM1_SelectHallSensor函数TIM1_SelectOnePulseMode函数TIM1_SelectOutputTrigger函数TIM1_SelectSlaveMode函数TIM1_SelectMasterSlaveMode函数TIM1_EncoderInterfaceConfig函数TIM1_PrescalerConfig函数,TIM1的编程方法(续),库函数：TIM1_CounterModeConfig函数TIM1_ForcedOC1Config函数TIM1_ForcedOC2Config函数TIM1_ForcedOC3Config函数TIM1_ForcedOC4Config函数TIM1_ARRPreloadConfig函数TIM1_SelectCOM函数TIM1_SelectCCDMA函数TIM1_CCPreloadControl函数TIM1_OC1PreloadConfig函数TIM1_OC2PreloadConfig函数TIM1_OC3PreloadConfig函数TIM1_OC4PreloadConfig函数TIM1_OC1FastConfig函数TIM1_OC2FastConfig函数TIM1_OC3FastConfig函数TIM1_OC4FastConfig函数,TIM1的编程方法(续),库函数：TIM1_ClearOC1Ref函数TIM1_ClearOC2Ref函数TIM1_ClearOC3Ref函数TIM1_ClearOC4Ref函数TIM1_GenerateEvent函数TIM1_OC1PolarityConfig函数TIM1_OC1NPolarityConfig函数TIM1_OC2PolarityConfig函数TIM1_OC2NPolarityConfig函数TIM1_OC3PolarityConfig函数TIM1_OC3NPolarityConfig函数TIM1_OC4PolarityConfig函数TIM1_SetCounter函数TIM1_CCxCmd函数TIM1_CCxNCmd函数TIM1_SelectOCxM函数TIM1_SetAutoreload函数,TIM1的编程方法(续),库函数：TIM1_SetCompare1函数TIM1_SetCompare2函数TIM1_SetCompare3函数TIM1_SetCompare4函数TIM1_SetIC1Prescaler函数TIM1_SetIC2Prescaler函数TIM1_SetIC3Prescaler函数TIM1_SetIC4Prescaler函数TIM1_SetClockDivision函数TIM1_GetCapture1函数TIM1_GetCapture2函数TIM1_GetCapture3
