1、12点阵汉字在HD系列机型中的应用在设备屏幕上显示输出在III型机打印输出一、加载字库通常加载字库有两种方式：内嵌常量式，外部参数文件形式内嵌变量式是指将字库点阵的内容以常量的形式写在程序源码中，如下文unsignedcharFontPattern[]={0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x10,0x10,0x10,0x10,0x10,0x00,0x00,0x10,0x00,0x00,0x00,0x00,0x6C,
2、0x48,0x48,0x00,0x00,0x00,0x00,0x00,0x00,0x00,0x00,…………0x21,0x00,0x79,0x00,0x49,0x40,0x7B,0xE0,0x49,0x40,0xFD,0x40,0x95,0x40,0xFD,0x40,0x01,0x40,0xFD,0x50,0x2A,0x50,0xCC,0x70,0x10,0x00,0x3D,0xF0,0x24,0x40,0x3C,0x40,0x24,0x40,0x7F,0xF0,0x52,0x40,0x7E,0x40,0x00
3、,0x40,0xFF,0x40,0x24,0x40,0xC4,0x40,0x20,0x80,0x7B,0xF0,0x49,0xC0,0x7A,0xA0,0x4C,0x90,0xFB,0xE0,0xAA,0x20,0xFB,0xE0,0x02,0x20,0xFF,0xE0,0x48,0x00,0x8B,0xF0};显示函数在调用时直接使用该参数即可，程序下载到手持机即可直接使用。外部参数文件形式是指将字库文件要外部基本参数的形式下载到手持机中，需要手持机程序在开机的时候检查该参数文件是否存在，如果不存在，则提示下
4、载该参数文件，如果存在，则加载该内容。unsignedchar*FontPattern;typedefunion{unsignedchars_char[4];unsignedlongl_word;}typ_long2char;/*以下部分为字库程序启动时检测加载*/{unsignedchartmpbuffer[16];typ_long2chartmplc;memcpy(tmpbuffer,(char*)Font12Addr,8);if(memcmp(tmpbuffer,"xf0x0fx00xff",4)
5、==0){memcpy(tmplc.s_char,tmpbuffer+4,4);Font12Length=tmplc.l_word;//获得字库长度FontPattern=malloc(Font12Length);if(FontPattern==NULL){//提示内存分配失败，程序将无法正常运行}memcpy(FontPattern,(char*)(Font12Addr+8),Font12Length);}else{//提示字库文件未下载}}/*加载完成*//*以下部分为字库文件下载*/voiddown_fo
6、nt(void){unsignedchar*frwBuffer;longDataLength;inttcnt;frwBuffer=malloc(0x40000);if(frwBuffer==NULL){DispStr_CE(0,1,"内存分配失败",DISP_POSITION
7、DISP_CLRSCR);DispStr_CE(0,6,"按任意键返回",DISP_POSITION);PressAnyKey();}else{DataLength=DownLoadData("font12",frwBuffer+8,0x
8、40000);if(DataLength>0){memcpy(frwBuffer,"xf0x0fx00xff",4);tmplc.l_word=DataLength;memcpy(frwBuffer+4,tmplc.s_char,4);if((DataLength%2)!=0)DataLength++;DataLenght+=8;for(tcnt=0;tcnt<4;tcnt++){if(FLASH_erase_block_2((char*)Font12Addr+tcnt*0x10000)!=0)brea
9、k;}if(tcnt!=4){DispStr_CE(0,1,"操作失败(1)",DISP_POSITION
10、DISP_CLRSCR);DispStr_CE(0,6,"按任意键返回",DISP_POSITION);ErrorBeep(0);free(frwBuffer);PressAnyKey();}else{if(FLASH_write_data_8M(Font12Addr,frwBu
