这篇博客探讨了STM32固件库从3.0版本以前到3.0及以后的变化，特别是stm32f10x_type.h头文件在新版库中被移除的情况。文章指出，在3.0版本以后，stm32f10x.h包含了原本在stm32f10x_type.h中的定义，并引入了stdint.h来处理标准整型定义，从而简化了库的使用。

在stm32f10x的3.5固件库中stm32f10x.h有以下代码（第478行开始）：

/**
  * @}
  */

#include "core_cm3.h"
#include "system_stm32f10x.h"
#include <stdint.h>

/** @addtogroup Exported_types
  * @{
  */  

/*!< STM32F10x Standard Peripheral Library old types (maintained for legacy purpose) */
typedef int32_t  s32;
typedef int16_t s16;
typedef int8_t  s8;

typedef const int32_t sc32;  /*!< Read Only */
typedef const int16_t sc16;  /*!< Read Only */
typedef const int8_t sc8;   /*!< Read Only */

typedef __IO int32_t  vs32;
typedef __IO int16_t  vs16;

typedef __I int16_t vsc16;  /*!< Read Only */
typedef __I int8_t vsc8;   /*!< Read Only */

typedef uint32_t  u32;
typedef uint16_t u16;
typedef uint8_t  u8;

typedef const uint32_t uc32;  /*!< Read Only */
typedef const uint16_t uc16;  /*!< Read Only */
typedef const uint8_t uc8;   /*!< Read Only */

typedef __IO uint32_t  vu32;
typedef __IO uint16_t vu16;
typedef __IO uint8_t  vu8;

typedef __I uint32_t vuc32;  /*!< Read Only */
typedef __I uint16_t vuc16;  /*!< Read Only */
typedef __I uint8_t vuc8;   /*!< Read Only */

typedef enum {RESET = 0, SET = !RESET} FlagStatus, ITStatus;

typedef enum {DISABLE = 0, ENABLE = !DISABLE} FunctionalState;
#define IS_FUNCTIONAL_STATE(STATE) (((STATE) == DISABLE) || ((STATE) == ENABLE))

typedef enum {ERROR = 0, SUCCESS = !ERROR} ErrorStatus;

/*!< STM32F10x Standard Peripheral Library old definitions (maintained for legacy purpose) */
#define HSEStartUp_TimeOut   HSE_STARTUP_TIMEOUT
#define HSE_Value            HSE_VALUE
#define HSI_Value            HSI_VALUE
