通用定时器是一个通过可编程预分频器驱动的16 位自动装载计数器构成。它适用于多种场合，包括测量

输入信号的脉冲长度(输入采集)或者产生输出波形（输出比较和PWM）。使用定时器预分频器和RCC 时钟控制器预分频器，脉冲长度和波形周期可以在几个微秒到几个毫秒间调整。

Section 19.1 TIM寄存器结构描述了固件函数库所使用的数据结构，Section 19.2 固件库函数介绍了函数库里的所有函数。

19.1 TIM寄存器结构

TIM 寄存器结构，TIM_TypeDeff，在文件“stm2f10x_map.h”中定义如下：

typedef struct {

vu16 CR1;

u16 RESERVED0; vu16 CR2;

u16 RESERVED1; vu16 SMCR;

u16 RESERVED2; vu16 DIER;

u16 RESERVED3; vu16 SR;

u16 RESERVED4; vu16 EGR;

u16 RESERVED5; vu16 CCMR1; u16 RESERVED6; vu16 CCMR2; u16 RESERVED7; vu16 CCER;

u16 RESERVED8; vu16 CNT;

u16 RESERVED9; vu16 PSC;

u16 RESERVED10; vu16 ARR;

u16 RESERVED11[3]; vu16 CCR1;

u16 RESERVED12; vu16 CCR2;

u16 RESERVED13; vu16 CCR3;

u16 RESERVED14; vu16 CCR4;

u16 RESERVED15[3]; vu16 DCR;

u16 RESERVED16; vu16 DMAR;

u16 RESERVED17; }TIM_TypeDef;

Table 457.例举了TIM所有寄存器 No 寄存器描述 1 CR1 控制寄存器1 2 CR2 控制寄存器2 3 SMCR 从模式控制寄存器 4 DIER DMA/中断使能寄存器 5 SR 状态寄存器 6 EGR 事件产生寄存器 7 CCMR1 捕获/比较模式寄存器1 8 CCMR2 捕获/比较模式寄存器2 9 CCER 捕获/比较使能寄存器 10 CNT 计数器寄存器 11 PSC 预分频寄存器 12 APR 自动重装载寄存器 13 CCR1 捕获/比较寄存器1 14 CCR2 捕获/比较寄存器2 15 CCR3 捕获/比较寄存器3 16 CCR4 捕获/比较寄存器4 17 DCR DMA控制寄存器 18 DMAR 连续模式的DMA地址寄存器三个 TIM 外设声明于文件： ...

#define PERIPH_BASE ((u32)0x40000000) #define APB1PERIPH_BASE PERIPH_BASE

#define APB2PERIPH_BASE (PERIPH_BASE + 0x10000) #define AHBPERIPH_BASE (PERIPH_BASE + 0x20000) #define TIM2_BASE (APB1PERIPH_BASE + 0x0000) #define TIM3_BASE (APB1PERIPH_BASE + 0x0400) #define TIM4_BASE (APB1PERIPH_BASE + 0x0800) ...

#ifndef DEBUG ...

#ifdef _TIM2

#define TIM2 ((TIM_TypeDef *) TIM2_BASE) #endif /*_TIM2 */ #ifdef _TIM3

#define TIM3 ((TIM_TypeDef *) TIM3_BASE) #endif /*_TIM3 */ #ifdef _TIM4

#define TIM4 ((TIM_TypeDef *) TIM4_BASE) #endif /*_TIM4 */ ...

#else /* DEBUG */ ...

#ifdef _TIM2

EXT TIM_TypeDef *TIM2; #endif /*_TIM2 */ #ifdef _TIM3

EXT TIM_TypeDef *TIM3; #endif /*_TIM3 */ #ifdef _TIM4

EXT TIM_TypeDef *TIM4; #endif /*_TIM4 */ ... #endif

使用Debug模式时，初始化指针TIM2, TIM3和TIM4于文件“st32f10x_lib.c”：

...

#ifdef _TIM2

TIM2 = (TIM_TypeDef *) TIM2_BASE; #endif /*_TIM2 */ #ifdef _TIM3

TIM3 = (TIM_TypeDef *) TIM3_BASE; #endif /*_TIM3 */ #ifdef _TIM4

TIM4 = (TIM_TypeDef *) TIM4_BASE; #endif /*_TIM4 */ ...

为了访问 TIM 寄存器，, _TIM，_TIM2, _TIM3和_TIM4 必须在文件“stm2f10x_conf.h”中定义如下：

...

#define _TIM #define _TIM2 #define _TIM3 #define _TIM4 ...

19.2.46 函数TIM_UpdateRequestConfig

Table 533. 函数 TIM_UpdateRequestConfig 函数名 TIM_UpdateRequestConfig 函数原形 void TIM_UpdateRequestConfig(TIM_TypeDef* TIMx, u16 TIM_UpdateSource) 功能描述设置TIMx更新请求源输入参数1 TIMx：x 可以是1,2,3,4,5,6,7,8来选择TIM外设输入参数2 TIM_UpdateSource：TIM更新请求源输出参数无返回值无先决条件无被调用函数无 TIM_UpdateSource：选择TIM更新源。 Table 534. TIM_UpdateSource值参数TIM_UpdateSource的值描述/CR1.0PM/[bit3] #define值 TIM_UpdateSource_Global 生成重复的脉冲：在更新事件时计数器不停止 0x0008 TIM_UpdateSource_Regular 生成单一的脉冲：计数器在一个更新事件停止 0x0000 例：

/* Selects the regular update source for TIM2 */

TIM_UpdateRequestConfig(TIM2, TIM_UpdateSource_Regular); 函数原型如下：

void TIM_UpdateRequestConfig(TIM_TypeDef* TIMx, u16 TIM_UpdateSource) {

/* Check the parameters */

assert_param(IS_TIM_ALL_PERIPH(TIMx));

assert_param(IS_TIM_UPDATE_SOURCE(TIM_UpdateSource));

if (TIM_UpdateSource != TIM_UpdateSource_Global)//根据一次脉冲？重复脉冲？的情况下设置URS {

/* Set the URS Bit */

TIMx->CR1 |= CR1_URS_Set;//导致中断或DMA请求的UEV: 计数器溢出/下溢 } else {

/* Reset the URS Bit */

TIMx->CR1 &= CR1_URS_Reset;

//导致中断或DMA请求的UEV:【1】.计数器溢出/下溢；【2】.设置EGR.UG位；【3】.从模式控制器产生的更新 } }

19.2.47 函数TIM_SelectHallSensor Table 535. 函数TIM_SelectHallSensor 函数名函数原形功能描述输入参数 1 输入参数 2 输出参数返回值先决条件 TIM_SelectHallSensor void TIM_SelectHallSensor(TIM_TypeDef* TIMx, FunctionalState Newstate) 使能或失能TIMx霍尔传感器接口 TIMx：x 可以是1,2,3,4,5,8来选择TIM外设 NewState：TIMx霍尔传感器接口的新状态（ENABLE 或 DISABLE）无无无
