STM32串口亂碼

庫函數默認8MHz晶振,應根據實際硬件選擇函數

 

# CMSIS/stm32f10x.hui

#define HSE_VALUE   ((uint32_t)12000000)
#if !defined  HSE_VALUE
 #ifdef STM32F10X_CL   
  #define HSE_VALUE    ((uint32_t)25000000) /*!< Value of the External oscillator in Hz */
 #else 
  #define HSE_VALUE    ((uint32_t)8000000) /*!< Value of the External oscillator in Hz */
 #endif /* STM32F10X_CL */
#endif /* HSE_VALUE */
