正文摘要:

为了工作方便想开发一个8继电器的开关电源作为工具使用；于是买了带单片机的模块，以及拿到C 语言源代码，如下。但是由于新手+基础薄弱，在修改一些语句后，编译仍然出现warnings，虽生存hex文件，但是XCOM串口工 ...

楼主这是某一个宝买的？

买了一个触摸屏幕准备做开关，配套的一个继电器模块，我想改一下里面的反馈代码；

如果是： STC12C2502AD
首先， include STC12C2502AD 的头文件，
然后， STC12C2502AD 需要设置端口模式，你可以参考手册。

然后，最关键的警告，你调用了 Eeprom 相关的函数，但是，你并没有提供实体函数，仅仅声明了，这么一个函数，内部是空的。
