STM8 symbol _assert_failed not defined (Debugstm8s_adc1.o )

symbol _assert_failed not defined (Debugstm8s_adc1.o )

在调试STM8的时候出现了这个问题，即函数assert_failed 未定义。查找问题，在stm8s_conf.h中对void assert_failed(u8* file, u32 line) 进行了申明，确没有文件中对该函数体进行编写，因此编译时找不到该函数而出错。因为之前没有使用库文件，全部自己调用寄存器编制的程序就没有碰到这种问题。
在头文件stm8s_conf.h中对函数有引用：
#ifdef USE_FULL_ASSERT
/**

• @brief The assert_param macro is used for function’s parameters check.
• @param expr: If expr is false, it calls assert_failed function
• which reports the name of the source file and the source
• line number of the call that failed.
• If expr is true, it returns no value.
• @retval : None
  /
  #define assert_param(expr) ((expr) ? (void)0 : assert_failed((uint8_t )FILE, LINE))
  / Exported functions ------------------------------------------------------- /
  void assert_failed(uint8_t file, uint32_t line);
  #else
  #define assert_param(expr) ((void)0)
  #endif / USE_FULL_ASSERT */

新建一个stm8s_assert_fail.c文件，在开始时包含stm8s_conf.h，添加函数体文件如下：
#include “stm8s_conf.h”
#ifdef USE_FULL_ASSERT
/**

• @brief Reports the name of the source file and the source line number
• where the assert_param error has occurred.
• @param file: pointer to the source file name
• @param line: assert_param error line source number
• @retval : None
  /
  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 %drn”, file, line) */

/* Infinite loop */
while (1)
{
}
}

#endif

编译即可通过。
