一一实现上面报错的这些函数。

回复【2楼】正点原子:
---------------------------------
这些函数 GUI库里面都有了就很奇怪啊

我的也遇到了这个问题啊

我也是这个问题弄了好久了明明里面都有函数也有定义干嘛老是报错我收不了了

cornrn · 发表于 2015-10-15 22:04:50

解决没？、、、、、

stophin · 发表于 2016-10-3 22:16:04

把extern这几个函数用extern "C"{}包起来
extern "C"
{
extern LCD_DisplayChar(...);
...
}
我是用CPP来引用的，可能比较特殊

我也遇到这样的问题，请问你解决了没

解决了吗，我也遇到这样的问题

终结者 · 发表于 2018-5-29 14:35:04

我的问题知道了，是因为在另一个工程生成LIB库文件的时候没有把对应的函数添加进去
