標(biāo)題: stm8s stm8s.h stm8s_conf.h頭文件的使用
在使用IAR for stm8編程的時(shí)候，會(huì)使用到stm8s.h的頭文件。

官網(wǎng)下載的庫(kù)函數(shù)直接用需要在main.c最后加上這么一段代碼，才可以編譯通過(guò)

#ifdef USE_FULL_ASSERT
void assert_failed(u8* file, u32 line)
{
  while (1)
  {
  }
}
#endif


stm8.h頭文件中最開(kāi)始會(huì)有這么一段


/* Uncomment the line below according to the target STM8S or STM8A device used in your
   application. */

/* #define STM8S208 */      /*!< STM8S High density devices with CAN */
/* #define STM8S207 */      /*!< STM8S High density devices without CAN */
/* #define STM8S007 */      /*!< STM8S Value Line High density devices */
/* #define STM8AF52Ax */    /*!< STM8A High density devices with CAN */
  #define STM8AF62Ax */    /*!< STM8A High density devices without CAN */
/* #define STM8S105 */      /*!< STM8S Medium density devices */
/* #define STM8S005 */      /*!< STM8S Value Line Medium density devices */
/* #define STM8AF626x */    /*!< STM8A Medium density devices */
/* #define STM8S103 */      /*!< STM8S Low density devices */
/* #define STM8S003 */      /*!< STM8S Value Line Low density devices */
/* #define STM8S903 */      /*!< STM8S Low density devices */


你可以針對(duì)自己的型號(hào)將前面的/*去除，另一種方法是不需要自己去除，options->c/c++ compiler->Preprocessor中的defined symbols中加入對(duì)應(yīng)的型號(hào)，如STM8AF62Ax
如若不然，會(huì)跳出錯(cuò)誤，因?yàn)閔文件中有這一段，未預(yù)定義則會(huì)報(bào)錯(cuò)

#if !defined (STM8S208) && !defined (STM8S207) && !defined (STM8S105) && \
    !defined (STM8S103) && !defined (STM8S903) && !defined (STM8AF52Ax) && \
    !defined (STM8AF62Ax) && !defined (STM8AF626x) && !defined (STM8S007) && \
    !defined (STM8S003)&& !defined (STM8S005)
#error "Please select first the target STM8S/A device used in your application (in stm8s.h file)"
#endif


stm8s_conf.h文件是包含了各個(gè)型號(hào)可用的外設(shè)，如

#if defined(STM8S208) ||defined(STM8S207) || defined(STM8S007) ||defined(STM8S103) ||\
    defined(STM8S003) || defined(STM8S903) || defined (STM8AF52Ax) || defined (STM8AF62Ax)
#include "stm8s_uart1.h"
#endif /* STM8S208 || STM8S207 || STM8S103 ||STM8S903 || STM8AF52Ax || STM8AF62Ax */


可見(jiàn)62ax有uart1 但是62a6并沒(méi)有uart1只有uart3 沒(méi)有看到哪里有具體說(shuō)明小型號(hào)對(duì)應(yīng)的編號(hào) 可以自己嘗試調(diào)試
