stm32f103转到ch32f203的时候，是不是所有的系统的.h文件，所有的系统的.c文件，都要替换掉？从代码到目录？

include paths也得重新定义？

您好，具体需要根据你用到的外设来看。若你是新开发一个项目，建议你在我们EVT例程的基础上进行开发，若你打算用之前的工程，具体需要根据你用到外设来做改动，某些外设一致，可以不用修改，可直接下载使用；有些外设存在差异，需要你对标准库进行一些移植修改，具体可参考附件FAQ手册，若改动较多，建议你直接在我们EVT工程的基础上进行一个移植，移植改动时需要注意我们寄存器的名称和ST有所不同，我看你的报错可能就是寄存器名称不同以及路径不正确导致的，关于寄存器的写法，具体可参考CH32F203应用手册的寄存器介绍。后面若有问题，可通过邮箱和我沟通（lzs@wch.cn）
