21天學(xué)嵌入式開發(fā),第十六講：高級控制定時器系統(tǒng),課程安排,高級控制定時器（TIM1）結(jié)構(gòu)TIM1寄存器結(jié)構(gòu)高級控制定時器（TIM1）的編程方法,高級控制定時器（TIM1）結(jié)構(gòu),TIM1由一個16位的自動裝載計數(shù)器組成，它由一個可編程預(yù)分頻器驅(qū)動。高級控制定時器TIM1和通用控制定時器TIMx是完全獨立的。TIM1定時器的主要功能特性。,時基單元,時基單元包含：計數(shù)器寄存器(TIM1_CNT)預(yù)分頻器寄存器(TIM1_PSC)自動裝載寄存器(TIM1_ARR)周期計數(shù)寄存器(TIM1_RCR),計數(shù)器模式,STM32高級控制定時器TIM1的16位計數(shù)器可以采用三種方式工作：向上計數(shù)模式向下計數(shù)模式中央對齊模式(向上/向下計數(shù)),向下重復(fù)計數(shù)器,計數(shù)器溢出/下溢時更新事件(UEV)它只能在重復(fù)向下計數(shù)達到0的時候產(chǎn)生。重復(fù)向下計數(shù)器在下述任一條件成立時遞減：向上計數(shù)模式下每次計數(shù)器溢出時。向下計數(shù)模式下每次計數(shù)器下溢時。中央對齊模式下每次溢出和下溢時。,TIM1的特殊工作模式,輸入捕獲模式PWM輸入模式強制輸出模式輸出比較模式PWM模式單脈沖模式(OPM)編碼器接口模式,與霍爾元件的接口,通用定時器和高級控制定時器可以聯(lián)合使用來實現(xiàn)與霍爾元件的接口。操作步驟,TIM1寄存器結(jié)構(gòu),typedefstructvu16CR1;/控制寄存器1u16RESERVED0;vu16CR2;/控制寄存器2u16RESERVED1;vu16SMCR;/從模式控制寄存器u16RESERVED2;vu16DIER;/DMA/中斷使能寄存器u16RESERVED3;vu16SR;/狀態(tài)寄存器u16RESERVED4;vu16EGR;/事件產(chǎn)生寄存器u16RESERVED5;vu16CCMR1;/捕獲/比較模式寄存器1u16RESERVED6;vu16CCMR2;/捕獲/比較模式寄存器2u16RESERVED7;vu16CCER;/捕獲/比較使能寄存器u16RESERVED8;vu16CNT;/計數(shù)器寄存器u16RESERVED9;vu16PSC;/預(yù)分頻寄存器u16RESERVED10;vu16ARR;/自動重裝載寄存器u16RESERVED11;vu16RCR;/周期計數(shù)寄存器u16RESERVED12;vu16CCR1;/捕獲/比較寄存器1u16RESERVED13;vu16CCR2;/捕獲/比較寄存器2u16RESERVED14;vu16CCR3;/捕獲/比較寄存器3u16RESERVED15;vu16CCR4;/捕獲/比較寄存器4u16RESERVED16;vu16BDTR;/剎車和死區(qū)寄存器u16RESERVED17;vu16DCR;/DMA控制寄存器u16RESERVED18;vu16DMAR;/連續(xù)模式的DMA地址寄存器u16RESERVED19;TIM1_TypeDef;,TIM1的編程方法,庫函數(shù)：TIM1_DeInit函數(shù)TIM1_TIM1BaseInit函數(shù)TIM1_OC1Init函數(shù)TIM1_OC2Init函數(shù)TIM1_OC3Init函數(shù)TIM1_OC4Init函數(shù)TIM1_BDTRConfig函數(shù)TIM1_ICInit函數(shù)TIM1_PWMIConfig函數(shù)TIM1_TIM1BaseStructInit函數(shù)TIM1_OCStructInit函數(shù)TIM1_ICStructInit函數(shù)TIM1_BDTRStructInit函數(shù)TIM1_Cmd函數(shù)TIM1_CtrlPWMOutputs函數(shù)TIM1_ITConfig函數(shù)TIM1_DMAConfig函數(shù),TIM1的編程方法(續(xù)),庫函數(shù)：TIM1_DMACmd函數(shù)TIM1_InternalClockConfig函數(shù)TIM1_ETRClockMode1Config函數(shù)TIM1_ETRClockMode2Config函數(shù)TIM1_ETRConfig函數(shù)TIM1_ITRxExternalClockConfig函數(shù)TIM1_TIxExternalClockConfig函數(shù)TIM1_SelectInputTrigger函數(shù)TIM1_UpdateDisableConfig函數(shù)TIM1_UpdateRequestConfig函數(shù)TIM1_SelectHallSensor函數(shù)TIM1_SelectOnePulseMode函數(shù)TIM1_SelectOutputTrigger函數(shù)TIM1_SelectSlaveMode函數(shù)TIM1_SelectMasterSlaveMode函數(shù)TIM1_EncoderInterfaceConfig函數(shù)TIM1_PrescalerConfig函數(shù),TIM1的編程方法(續(xù)),庫函數(shù)：TIM1_CounterModeConfig函數(shù)TIM1_ForcedOC1Config函數(shù)TIM1_ForcedOC2Config函數(shù)TIM1_ForcedOC3Config函數(shù)TIM1_ForcedOC4Config函數(shù)TIM1_ARRPreloadConfig函數(shù)TIM1_SelectCOM函數(shù)TIM1_SelectCCDMA函數(shù)TIM1_CCPreloadControl函數(shù)TIM1_OC1PreloadConfig函數(shù)TIM1_OC2PreloadConfig函數(shù)TIM1_OC3PreloadConfig函數(shù)TIM1_OC4PreloadConfig函數(shù)TIM1_OC1FastConfig函數(shù)TIM1_OC2FastConfig函數(shù)TIM1_OC3FastConfig函數(shù)TIM1_OC4FastConfig函數(shù),TIM1的編程方法(續(xù)),庫函數(shù)：TIM1_ClearOC1Ref函數(shù)TIM1_ClearOC2Ref函數(shù)TIM1_ClearOC3Ref函數(shù)TIM1_ClearOC4Ref函數(shù)TIM1_GenerateEvent函數(shù)TIM1_OC1PolarityConfig函數(shù)TIM1_OC1NPolarityConfig函數(shù)TIM1_OC2PolarityConfig函數(shù)TIM1_OC2NPolarityConfig函數(shù)TIM1_OC3PolarityConfig函數(shù)TIM1_OC3NPolarityConfig函數(shù)TIM1_OC4PolarityConfig函數(shù)TIM1_SetCounter函數(shù)TIM1_CCxCmd函數(shù)TIM1_CCxNCmd函數(shù)TIM1_SelectOCxM函數(shù)TIM1_SetAutoreload函數(shù),TIM1的編程方法(續(xù)),庫函數(shù)：TIM1_SetCompare1函數(shù)TIM1_SetCompare2函數(shù)TIM1_SetCompare3函數(shù)TIM1_SetCompare4函數(shù)TIM1_SetIC1Prescaler函數(shù)TIM1_SetIC2Prescaler函數(shù)TIM1_SetIC3Prescaler函數(shù)TIM1_SetIC4Prescaler函數(shù)TIM1_SetClockDivision函數(shù)TIM1_GetCapture1函數(shù)TIM1_GetCapture2函數(shù)TIM1_GetCapture3
