论坛抢的板子已经到了些天了。其实已经试过了。由于平时没有发帖的习惯，所以一直没发贴。这次应要求发篇帖子。

一、首先是开发环境
1、按照以往的习惯，继续试用keil，MDK5.17及芯片资料，ST-Link驱动，Cube已经打包在末尾提供下载。
由于弘扬正版的需要，我并不会想百度上其他的人那样给出破解工具。l
经过一路NEXT，Kei就安装完成了。keil注册略过。 MDK5.17.png

2、安装st-Link驱动，按照对应版本解压安装就行了。
3、安装STM32 ST-LINK Utility，同样一路next即可。好像ST-LINK Utility会自动安装ST-link的驱动（我还没有验证）。

至此环境已经配置完成。
二、编译例程
1、解压cube包，在STM32Cube_FW_L4_V1.0.0\Projects\STM32L476RG-Nucleo\Examples\目录下有多个例程可以测试。先一个喜欢的打开，我选的是UART\UART_TwoBoards_ComIT__。打开例子按图进行一下配置
