准备测试CH565开发板的千兆网络通讯，查看CH565的数据手册里面也是让自己看示例程序，示例程序里面调用很多寄存器，初始化等函数，没办法跟数据手册对应起来。直接看程序是一头雾水

        想请教下，有没有谁跑过这个例程，然后洗了调试总结分享之类的帖子，或者文章。

我们EVT代码是底层的MAC帧收发。

TCP\UDP需要自行组包，或者跑以太网协议栈，如TCP\UDP例程可以发送邮件至sj@wch.cn获取

你好，我通过mj@wch.cn获取的TCP/UDP的DEMO程序，编译出错，应该是文件路径的问题，但是我把路径修改之后，还是编译出错。帮忙分析下，是哪里没设置好。

提示信息如下：

您好，以太网代码涉及到H C A文件的工程包含，建议联系邮箱mj@wch.cn进行确认。

       另外请教个问题，CH565的数据手册对千兆网络通讯章节写的特别简单，对功能和寄存器都没有进行介绍，DEMO程序中这部分的MAC调用函数也都是封装好打不开的。

       如果需要更换不同的PHY芯片，移植起来会非常不方便，出现其他调试过程的问题，自己也无法很好的进行排查。

       有更详细一点的数据手册可以提供给我们进行参考学习么？

您好，以太网相关代码我们主要以函数库形式提供，我们会提供类似TCP UDP的例程代码，如果有类似需求可以发送到mj@wch.cn进行咨询

DEMO程序已经邮件发给我了，我了解下你们是否还有除了DEMO程序之外的，可供参考的文档资料。

另外DEMO程序中，的TCP_clientl例程中，主动发送数据是采用哪个函数？

是通过如下两个函数么，还是有其他函数：

ETH_DMATxDescChainInit(ETH_DMADESCTypeDef *DMATxDescTab, UINT8* TxBuff, UINT32 TxBuffCount)；

void ETH_DMARxDescChainInit(ETH_DMADESCTypeDef *DMARxDescTab, UINT8 *RxBuff, UINT32 RxBuffCount)；
