《6》关于cubesuite的code generator的使用，同工程多次生成代码的问题 [复制链接]

关于cubesuite的code generator的使用，同工程多次生成代码的问题；
因为有时候我们最先使用code generator进行io口功能配置的时候，不一定配置得比较合理，所以有时候需要进行更改配置；在code generator的使用中发现，多次使用code generator进行Generate Code配置生成代码是可以不覆盖之前的用户代码的，最近使用的时候发现的，这里给不是很熟悉的朋友介绍一下~~
下面是之前的一段代码
r_cg_main.c

复制代码

在自动生成的代码中有很多地方有类似注释：
/* Start user code 。。。。。。. Do not edit comment generated here */
这里可以添加用户代码~~~
/* End user code. Do not edit comment generated here */这段文字是说明，这里添加的用户代码在生成代码的时候将不会被覆盖，就是说你无论使用多少次code generator的Generate Code这两行注释的内部代码都不会改变。
这里特别说明一下，代码放在上面注释之外再次使用Generate Code生成代码时是会被清除的，如果不再使用Generate Code生成代码则没有影响。
并且这里不可以通过复制自行增加相同注释而达到同样的保护效果。
其实对于

R7F0C80212

芯片来说功能相对简单，使用code generator来进行配置是相当简便的，功能也很完善。对于项目开发也完全够用，使大家可以专注于项目本身的代码构建。
