在单片机keil编辑其中如何创建自己的函数库。方便以后自己调用

#ifndef __SDFILE_H__
#define __SDFILE_H__

#pragma SAVE
#pragma REGPARMS
//单片机的SPI初始化
extern void MCU_init();
//SD卡的SPI初始化
extern void SD_SPI_init();
//文件初始化
extern void FAT32_Init();
//小端转大端
extern unsigned long Little_To_Big(unsigned char *dat,unsigned char len);
//打开或创建文件
extern unsigned char fopen(char file_name[8]);
//关闭文件代号
extern void fclose(unsigned pfile);
//文件定位
extern void fseek(unsigned char pfile,unsigned long len);
//读区文件内容
extern void fread(unsigned char pfile,unsigned char *store,unsigned int read_num);
//写入文件内容,只能写在结尾
extern void fwrite(unsigned char pfile,unsigned char *store,unsigned int write_num);
//写入文件内容,删除原来文件内容
extern void fwriteall(unsigned char pfile,unsigned char *store,unsigned int write_num);
//汉字库与液晶汉字库的转换
extern void HZKLCD(unsigned char *ch,unsigned char *CH);
//字符串转数字
extern unsigned int atoi(unsigned char *array,unsigned char len);
//寻找内容的位置
extern unsigned long find1(unsigned char pfile,unsigned char pfile1,unsigned char len1,unsigned char *array,unsigned char len,unsigned char len2);
