在添加固件库时，提示出错#error clnk Debug\test.lkf:1 symbol _assert_failed not defined (Debug\wy_tim6.o )
觉得问题出在 assert_param(IS_TIM6_SLAVE_MODE_OK(TIM6_SlaveMode));没明白这是什么意思？
#ifdef DEBUG
/*******************************************************************************
* Macro Name : assert_param
* Description : The assert_param macro is used for function's parameters check.
* It is used only if the library is compiled in DEBUG mode.
* Input : - 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.
* Return : None
*******************************************************************************/
#define assert_param(expr) ((expr) ? (void)0 : assert_failed((u8 *)__FILE__, __LINE__))
/* Exported functions ------------------------------------------------------- */
void assert_failed(u8* file, u32 line);
#else
#define assert_param(expr) ((void)0)
#endif /* DEBUG */
这个文件的最开头有一段注释，你看看
/* Uncomment the line below to compile the library in DEBUG mode, this will expanse
the "assert_param" macro in the firmware library code (see "Exported macro"
section below) */
/*#define DEBUG 1*/
如果你不需要输出这些debug信息，你就#define DEBUG 0试试看
/**
* @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 %d\r\n", file, line) */
