STM32-Cube定时器TIM

一、内部时钟源

1、创建项目

File → New → STM32 project
选择STM32F103C8T6单片机，命名TIM

2、配置单片机

1.打开USART1，方便我们与电脑连接查看数据

开启UART1并开启中断。

2、设置时钟源

开启外部高速晶振
将时钟频率设置为72MHz
设置调试模式
打开定时器并且设置分频器和重装值

3、代码部分

1.查看定时器的重装计数值

启动定时器功能，计数器开始计数。

c 复制代码

  HAL_TIM_Base_Start(&htim4);

定义变量来存放计数值。

c 复制代码

int counter = 0;

通过串口发送到电脑端，方便查看。

包含需要用到头文件

c 复制代码

/* USER CODE BEGIN Includes */
#include <stdio.h>
#include <string.h>
/* USER CODE END Includes */

读取计数值

c 复制代码

counter = __HAL_TIM_GET_COUNTER(&htim4);

通过串口发送数据

c 复制代码

 	 char message[20];
  
	  sprintf(message, "counter: %d", counter);
	  HAL_UART_Transmit(&huart1, (uint8_t*)message, strlen(message), HAL_MAX_DELAY);
	  HAL_Delay(99);

编译下载程序，串口助手成功接收到数据，因为主程序有延迟100ms函数，串口助手每隔100ms接收一次数据，计数值刚好相隔100个数，证明此程序正常。

2.定时器中断

开启定时器4的中断功能
将启动定时器的函数改成中断模式的函数。

c 复制代码

HAL_TIM_Base_Start_IT(&htim4);

重写回调函数，计数器每次计数完成会产生一次时间更新，调用一次回调函数，对其重写。

stm32f1xx_hal_tim.c中复制回调函数名，在main.c中进行重写。

c 复制代码

/* USER CODE BEGIN 0 */
char data[] = "hello!";
void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim) {
	if (htim = &htim4) {
		HAL_UART_Transmit_IT(&huart1, (uint8_t*)data, 6);
	}
}
/* USER CODE END 0 */

将上个流程中循环语句中的代码删除，因为使用了回调函数，不需要那些。再编译下载，发现两次收到的数据相隔1秒，测试成功。

二、外部时钟源

1、创建项目

File → New → STM32 project
选择STM32F103C8T6单片机，命名TIM_ExternalClock

2、配置单片机

1. 配置定时器

ETR引脚有两种路径进入触发控制器，直接进入（模式2）和通过触发器进入（模式1）
因为TIM3、TIM4并没有引出外部触发器ETR引脚，所以这次我们使用TIM2定时器。

2. 配置IIC来驱动OLED显示

开启IIC2功能
项目管理，为每个外设创建一个头文件和源文件，然后保存生成代码。

3、代码部分

1. 0.96寸4引脚OLED显示模块

字库和屏幕的驱动的头文件，添加到项目的Core → Inc 里。

 * 本驱动库针对波特律动·keysking的STM32教程学习套件进行开发
 * 在其他平台或驱动芯片上使用可能需要进行移植
 *
 * @note
 * 使用流程:
 * 1. STM32初始化IIC完成后调用OLED_Init()初始化OLED. 注意STM32启动比OLED上电快, 可等待20ms再初始化OLED
 * 2. 调用OLED_NewFrame()开始绘制新的一帧
 * 3. 调用OLED_DrawXXX()系列函数绘制图形到显存 调用OLED_Printxxx()系列函数绘制文本到显存
 * 4. 调用OLED_ShowFrame()将显存内容显示到OLED

2. 主程序部分

再main.c中添加OLED的头文件和stdio.h文件

c 复制代码

/* USER CODE BEGIN Includes */
#include "oled.h"
#include <stdio.h>
/* USER CODE END Includes */

初始化OLED和启动定时器开始计数并记录下来

c 复制代码

  /* USER CODE BEGIN 2 */
  OLED_Init();
  HAL_TIM_Base_Start(&htim2);

  int counter = 0;
  char message[20];
  /* USER CODE END 2 */
  while (1)
  {
	  OLED_NewFrame();

	  counter = __HAL_TIM_GET_COUNTER(&htim2);
	  sprintf(message, "次数: %d", counter);
	  OLED_PrintString(0, 0, message, &font16x16, OLED_COLOR_NORMAL);

	  OLED_ShowFrame();

	  HAL_Delay(200);

    /* USER CODE END WHILE */

    /* USER CODE BEGIN 3 */
  }

当在PA0引脚接一个开关，按动开关，我们发现记录的次数是跳动上涨的，这是因为我们没有使用输入滤波器，我们将滤波器设置成16，保存代码，编译下载，发现不会跳动上涨，而是正常1个数1个数的上涨。

3、外部始种模式1

在模式配置中修改成这样，保存编译下载，还是一样，成功
