移植之前 必须保证 成功移植了文件系统,这是在VS2008上运行通过的;
//移植的时候要修改printf 函数为LCD的打印一个点的函数,与文件系统相关的函数 酌情修改
这是显示效果,16*16 的GBK字库 字库的文件名是 "font.DZK"
- #include "stdio.h"
- #define FONT_SIZE 32//定义单个汉字所占的字节数
- void Display(FILE *f,char *str);
- void Displays(FILE *f,char *str,unsigned char count);
- int main(void)
- {
- FILE *f;
- f=fopen("font.DZK",r");
- if(f==NULL)
- {
- printf("error..");
- return 0;
- }
- Displays(f,"您好",2);
- fclose(f);
- return 0;
- }
- void GetFont(FILE *f,char *str,unsigned char *buff)
- {
- unsigned char High=*str;
- unsigned char Low=*(str+1);
- unsigned long offset;
- High-=0x81;
- if(Low<0x7f)
- Low-=0x40;
- else
- Low-=0x41;
- offset=(unsigned long)(High*190+Low)*FONT_SIZE;
- fseek(f,offset,0);
- fread(buff,FONT_SIZE,1,f);
- }
- void Display(FILE *f,char *str)
- {
- char i,j;
- unsigned char buff[FONT_SIZE],temp;
- GetFont(f,str,buff);
- for(i=0;i<32;i+=2)
- {
- temp=buff[i];
- for(j=0;j<8;j++)
- {
- if(temp&0x80)
- printf("*");
- else
- printf(" ");
- temp<<=1;
- }
- temp=buff[i+1];
- for(j=0;j<8;j++)
- {
- if(temp&0x80)
- printf("*");
- else
- printf(" ");
- temp<<=1;
- }
- printf("\n");
- }
- }
- void printblank(void)
- {
- unsigned char i;
- for(i=0;i<16;i++)
- printf(" ");
- }
- void Displays(FILE *f,char *str,unsigned char count)
- {
- unsigned char i;
- for(i=0;i<count;i++,str+=2)
- {
- Display(f,str);
- printblank();
