使用J-Link RTT Viewer

参考安富莱的教程

1 .将RTT的文件添加到工程中，RTT在自带的Jlink驱动中有

2. 添加API函数

 /* USER CODE BEGIN 2 */
	/* 配置通道 0，上行配置*/
	SEGGER_RTT_ConfigUpBuffer(0, "RTTUP", NULL, 0, SEGGER_RTT_MODE_NO_BLOCK_SKIP);
	/* 配置通道 0，下行配置*/
	SEGGER_RTT_ConfigDownBuffer(0, "RTTDOWN", NULL, 0, SEGGER_RTT_MODE_NO_BLOCK_SKIP);
	SEGGER_RTT_SetTerminal(0);

3.打印输出

// 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());
}

// 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());
}

// 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());
}

// 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());
}

4.测试
