使用Event Recoder 调试

易水寒陈2026-01-02 9:35

参考安富莱的教程，记录狂暴模式下的EventRecoder功能

1.添加EventRecoder

开启EventRecoder功能，STDOUT选择EVR

2

3

EventCoder.h文件中配置

4.Keil配置

将IRAM1分配一部分空间给IRAM2.IRAM2勾选为NoInit

5

选择为IRAM2

6添加代码

c 复制代码

int main(void)
{

  /* USER CODE BEGIN 1 */
	EventRecorderInitialize(EventRecordAll, 1U);
	EventRecorderStart();
  /* USER CODE END 1 */

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

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

c 复制代码

// LED闪烁任务
void LED_Task(void)
{
//	SEGGER_RTT_printf(0,"LED_Task is Running, tick is %llu \r\n", get_system_time_64());
	printf("LED_Task is Running, tick is %llu \r\n", get_system_time_64());
}

// 按键扫描任务
void KeyScan_Task(void)
{
//  SEGGER_RTT_printf(0,"keyScan_task is Running, tick is %llu \r\n", get_system_time_64());
	printf("keyScan_task is Running, tick is %llu \r\n", get_system_time_64());
}

// 数据处理任务
void DataProcess_Task(void)
{
// SEGGER_RTT_printf(0,"DataProcess_Task is Running, tick is %llu \r\n", get_system_time_64());
	printf("DataProcess_Task is Running,tick is %llu \r\n", get_system_time_64());
}

// 显示任务
void Display_Task(void)
{
//	SEGGER_RTT_printf(0,"Display_Task is Running, tick is %llu \r\n", get_system_time_64());
	printf("Display_Task is Running, tick is %llu \r\n", get_system_time_64());
}

并且勾选使用微库

测试

可以看到正确被打印

使用时间测量功能

需要注意的是仿真器的trace的时钟要和mcu的时钟相同
