STM32CbueMX基于HAL库的基本定时器TIM6的实验演示
作者：互联网
按照如下步骤进行基本定时器TIM6的实验，本实验利用的是STM32F103.
1.CbueMX软件的版本如下:
2.CbueMX软件的配置如下：
其余的配置是常规配置，如果不懂请参见我之前的文章
3.打开中断：
中断的优先级可以自行配置，这里不在赘述。
4.点击生成初始化代码：
5.生成初始化代码如下：

#include "tim.h"

TIM_HandleTypeDef htim6;
/* TIM6 init function */
void MX_TIM6_Init(void)
{

htim6.Instance = TIM6;

6.生成代码以后，因为是定时器，所以在自己进行计时的时候肯定要开启中断，那么在主函数里面开启中断，利用开启中断的函数：
/* USER CODE BEGIN Header */
/**

/* USER CODE END 2 */
/* Infinite loop */
/* USER CODE BEGIN WHILE */
while (1)
{
/* USER CODE END WHILE */
/* USER CODE BEGIN 3 */
}
/* USER CODE END 3 */
}
/**
* @brief System Clock Configuration
* @retval None
*/
void SystemClock_Config(void)
{
RCC_OscInitTypeDef RCC_OscInitStruct = {0};
RCC_ClkInitTypeDef RCC_ClkInitStruct = {0};
RCC_PeriphCLKInitTypeDef PeriphClkInit = {0};
/** Initializes the RCC Oscillators according to the specified parameters
* in the RCC_OscInitTypeDef structure.
*/
RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_LSI|RCC_OSCILLATORTYPE_HSE
|RCC_OSCILLATORTYPE_LSE;
RCC_OscInitStruct.HSEState = RCC_HSE_ON;
RCC_OscInitStruct.HSEPredivValue = RCC_HSE_PREDIV_DIV1;
RCC_OscInitStruct.LSEState = RCC_LSE_ON;
RCC_OscInitStruct.HSIState = RCC_HSI_ON;
RCC_OscInitStruct.LSIState = RCC_LSI_ON;
RCC_OscInitStruct.PLL.PLLState = RCC_PLL_ON;
RCC_OscInitStruct.PLL.PLLSource = RCC_PLLSOURCE_HSE;
RCC_OscInitStruct.PLL.PLLMUL = RCC_PLL_MUL9;
if (HAL_RCC_OscConfig(&RCC_OscInitStruct) != HAL_OK)
{
Error_Handler();
}
/** Initializes the CPU, AHB and APB buses clocks
*/
RCC_ClkInitStruct.ClockType = RCC_CLOCKTYPE_HCLK|RCC_CLOCKTYPE_SYSCLK
|RCC_CLOCKTYPE_PCLK1|RCC_CLOCKTYPE_PCLK2;

if (HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_2) != HAL_OK)
{

}

if (HAL_RCCEx_PeriphCLKConfig(&PeriphClkInit) != HAL_OK)
{
Error_Handler();
}
}
/* USER CODE BEGIN 4 */
/* USER CODE END 4 */
/**

* @retval None
*/
void Error_Handler(void)
{
/* USER CODE BEGIN Error_Handler_Debug */
/* User can add his own implementation to report the HAL error return state */
__disable_irq();
while (1)
{
}
/* USER CODE END Error_Handler_Debug */
}
#ifdef USE_FULL_ASSERT
/**

* where the assert_param error has occurred.

void assert_failed(uint8_t *file, uint32_t line)
{
/* USER CODE BEGIN 6 */
/* User can add his own implementation to report the file name and line number,
ex: printf("Wrong parameters value: file %s on line %d\r\n", file, line) */
/* USER CODE END 6 */
}
#endif /* USE_FULL_ASSERT */
/************************ (C) COPYRIGHT STMicroelectronics *****END OF FILE****/
7.接下来就是在中断回调函数里面编写在定时器定时的时间到了以后要执行的动作：
/**
* @brief Period elapsed callback in non-blocking mode
* @param htim TIM handle
* @retval None
*/
__weak void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim)
{
/* Prevent unused argument(s) compilation warning */
// UNUSED(htim);//注释掉这个
//然后在这个位置进行代码的编写
/* NOTE : This function should not be modified, when the callback is needed,
the HAL_TIM_PeriodElapsedCallback could be implemented in the user file
*/
}
寻找到这个弱定义的函数，然后进行重新编辑或者直接在这个函数里面加进去需要执行的代码就可以了.
或者在你想的地方编写重新编写一下这个回调函数也可以
例如：
void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim)
{
if(htim==&htim6)
{
time1_counter++; //每次时间计数器到达计数周期就会调用回调函数进行中断累加变量加1
}
}
然后进行编译下载就可以了。
这个地方需要说明的是如何进行定时器的计算，如上图，套入公式就可以了
T=(71+1)(1000+1)/72000000；这里地 72000000就是单片机设定的频率72Mhz。
