修改的文件：port.h；port.c；portserial.c；porttimer.c stm32f4xx_it.c, main.h,freertos.c
,
一、修改port.h文件
#ifndef _PORT_H
#define _PORT_H
#include <assert.h>
#include <inttypes.h>
#include "stm32f4xx_hal.h" //需要修改的
#define INLINE inline
#define PR_BEGIN_EXTERN_C extern "C" {
#define PR_END_EXTERN_C }
#define ENTER_CRITICAL_SECTION( ) __set_PRIMASK(1) //需要修改的
#define EXIT_CRITICAL_SECTION( ) __set_PRIMASK(0) //需要修改的
typedef uint8_t BOOL;
typedef unsigned char UCHAR;
typedef char CHAR;
typedef uint16_t USHORT;
typedef int16_t SHORT;
typedef uint32_t ULONG;
typedef int32_t LONG;
#ifndef TRUE
#define TRUE 1
#endif
#ifndef FALSE
#define FALSE 0
#endif
#endif
二、修改stm32f4xx_it文件
