芯科BG22学习笔记：10-如何实现RTT log打印
实验目的：log日志记录对开发嵌入式产品非常重要。尤其对于基于连接的无线产品。因为使用断点可能会导致连接中断，而通过浏览log日志可以很容易地解决问题。添加RTT组件并修改相关的.c和.h文件实现RTT log打印，通过Jlink工具J-Link RTT Viewer V6.86d实现log的显示。
实验环境：Simplicity Studio V5 / GSDK4.4.3
实验器材：Thunderboard BRD4184A
实验开始：
1. 新建工程，蓝牙工程输入soc empty， 普通MCU工程输入empty c
2. 双击SLCP文件，在Soft Components安装第三方的两个RTT组件
- Third Party → SEGGER → RTT → SEGGER RTT
- Third Party → SEGGER→ RTT→ SEGGER RTT printf
3. 添加log.h文件

5. 编译程序并下载到开发板中
6. 打开电脑上的J-Link RTT Viewer V6.86d，选择BG22的型号; 此处选择512的型号（选择V6.86版本：过早版本没有BG22芯片的选项，过新版本有些Jlink设备有限制）
7. RTT log显示如下
完
