标题: M452/453 USB 虚拟串口代码
代码烧录到芯片M452/453 后，USB 连 PC 机，会有一个 M453_VCOM 设备，更新设备驱动——在软件包内——会多出一个串口。
打开一个串口助手，会不停的收到数据。在串口助手中也可以发送给 M452/453

详细代码：

但还是感谢楼主的奉献。
我的MDK是V4.23，编译M451SeriesBSP_CMSIS_v3.00.005的例程没有问题。

我用的是MDK5.10。出现这些问题，主要是 stdint.h 等几个头文件已在 MDK5 的系统文件夹里，所以这个软件包里就没加上。您可以自己找到拷贝过来就没问题了。

不像楼主说的那么简单，我试了试，不行。

作者: boltnut 时间: 2015-10-29 20:08
把檔案的路徑調整一下,就 OK 了 !

作者: hemingxian 时间: 2015-10-30 11:40
能将你调整好路径的包发上来吗？我来测试一下真假

用内部HIRC，不能够正常识别VCOM。请问这是必须要用外部晶振经过PLL输出才能够给USB提供时钟么？没有外部晶振是不可以的么。切盼回复

USB 需要一个 48MHz 的时钟，内部 HIRC 是 22.1184MHz ，无法倍频得到 48MHz

我安装了MDK5.10，并安装了Nuvoton.NuMicro_DFP.1.0.5，可是却出现了这个
楼主能给个支持M451系列的包吗？

装一下芯唐的 Nu_Link Keil Driver 就可以了，在芯唐网站可以下载。

作者: hemingxian 时间: 2016-1-30 12:47
谢谢楼主指点。装了芯唐的 Nu_Link Keil Driver 就没有弹出错误了，可是我在编译时却出现下述错误，不知道应该如何处理。请楼主给予指点。

找到原因了，是路径设置有误，在Project\Options for Target ‘USBD_VCOM’\C/C++\Include Paths\ 中添加
..\Library\CMSIS\Include
即可编译成功。看来是原文路径设置有误。
