void
assert_failed(u8* file, u32 line);这个函数只是在“stm8s_conf.h”这个文件里面声明，用来在返回值验证出错的时候调用，所以还需要在一个恰当的地方将这个函数实现。一般我是“main.c”

解决方案：

1.

void assert_failed(u8* file, u32 line) {    /* User can add his own implementation to report the file name and line number,      ex: printf("Wrong parameters value: file %s on line %d\r\n", file, line) */   /* Infinite loop */   while (1)   {   } } 加上这个 2.在stm8s_conf.h 中注释 #define USE_FULL_ASSERT
