STM32F030R8Tx加入RTT打印

• 用STM32CubeMX工具生成STM32F030R8Tx MCU的Keil工程
• 在工程中加入SEGGER_RTT.c和SEGGER_RTT_printf.c 

• sdk_config.h主要是配置DEBUG开关宏，内容如下

#ifndef SDK_CONFIG_H
#define SDK_CONFIG_H

	
#define STM_MODULE_ENABLED(module) \
    ((defined(module ## _ENABLED) && (module ## _ENABLED)) ? 1 : 0)

// >\n

//==================================================================================================





//==========================================================


//  DEBUG配置
//  DEBUG使能
#ifndef DEBUG_ENABLED
#define DEBUG_ENABLED 1
#endif


//  ASSERT参数检查使能
#ifndef IS_USE_FULL_ASSERT
#define IS_USE_FULL_ASSERT 	1
#endif
#if IS_USE_FULL_ASSERT
#define USE_FULL_ASSERT
#endif
// 

// >
#endif //SDK_CONFIG_H

• 准备一个stm_log.h文件，内容如下

#include "sdk_config.h"
#include "SEGGER_RTT.h"
#include "stdio.h"
#ifndef STM_LOG_H__
#define STM_LOG_H__


#ifdef __cplusplus
extern "C" {
#endif

#if STM_MODULE_ENABLED(DEBUG)




/**
* @brief RTT打印宏
* @note 
* - 最多不能超过128个字符否则出错
*/
#define NRF_LOG_INFO(fmt,args...) \
      do					\
			{						\
				sprintf(_SEGGER_RTT.aUp->pBuffer,fmt,##args); \
				SEGGER_RTT_WriteString(0, _SEGGER_RTT.aUp->pBuffer);	\
				SEGGER_RTT_WriteString(0,"\r\n");  \
			}while(0)

      
#define RTT_INIT()  \
SEGGER_RTT_Init()			
			
#else
#define NRF_LOG_INFO(fmt,args...) ((void)0)
     
#define RTT_INIT()  ((void)0)
	
#endif


		
#ifdef __cplusplus
}
#endif
		
#endif
			

• 在main.c中入包含stm_log.h头文件，在main函数中初时化及调用打印，内容如下

/**
  * @brief  The application entry point.
  * @retval int
  */
int main(void)
{
  /* USER CODE BEGIN 1 */
	RTT_INIT();
	
  /* USER CODE END 1 */

  /* MCU Configuration--------------------------------------------------------*/

  /* Reset of all peripherals, Initializes the Flash interface and the Systick. */
  HAL_Init();

  /* USER CODE BEGIN Init */

  /* USER CODE END Init */

  /* Configure the system clock */
  SystemClock_Config();

  /* USER CODE BEGIN SysInit */

  /* USER CODE END SysInit */

  /* Initialize all configured peripherals */
  /* USER CODE BEGIN 2 */

  /* USER CODE END 2 */

  /* Infinite loop */
  /* USER CODE BEGIN WHILE */
  while (1)
  {
    /* USER CODE END WHILE */
    HAL_Delay(1000);
    NRF_LOG_INFO("main is running!");
    /* USER CODE BEGIN 3 */
  }
  /* USER CODE END 3 */
}

• 运行打印结果如下

• 在main文件中的assert_failed函数中加入RTT打印

#ifdef  USE_FULL_ASSERT
/**
  * @brief  Reports the name of the source file and the source line number
  *         where the assert_param error has occurred.
  * @param  file: pointer to the source file name
  * @param  line: assert_param error line source number
  * @retval None
  */
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,
     tex: printf("Wrong parameters value: file %s on line %d\r\n", file, line) */
  /* USER CODE END 6 */
  NRF_LOG_INFO("%s,line %d",file,line);
  while(1);

}
#endif /* USE_FULL_ASSERT */

•  在main函数中加入会出错的测试代码

• 运行结果如下

• 找到 ../Drivers/STM32F0xx_HAL_Driver/Src/stm32f0xx_hal_gpio.c文件中的第185行，引脚参数抛出了断言
