使用过hal里边的例程，还是有好多自己添加的东西不太懂，还麻烦各位大神指教
C:\ti\Hercules\Hercules Safety MCU Demos
Hercules Safety MCU Demos-4.0.0-installer.exe 这个安装文件下载了吗，里面例子很丰富。
或者在TI网上搜索spnc034
安装后在目录 C:\ti\Hercules\Hercules Safety MCU Demos\4.0.0\TMS570LC43x_target_sources\demo-app\source
下面，随便打开个都有用到SCI串口收发
Hi Chenyang,
用HAL Code Generator新建工程，选定device后，在Help-->Help Topics-->Examples里有很多例程，且每个例子均有图形化讲解，比较容易懂。
另外，新建工程步骤及SCI例程见附件，可供参考。
