2、i = 8; i < 16; i+ lcd_data_wr(shuzii,1; void lcd_num_wr(uchar row,uchar col,uchar n,uchar *str uchar i; for(i = 0 ; i < n; i+ if( col > 15 row+; col = col - 16; lcd_shuzi_wr(row,col,str+i*16; col+; void lcd_bmp_wr(uchar posx,uchar posy,uchar wth,uchar hgh,uchar *bm p /posx 取值为 03,posy = 012

3、8,图片的长 wth 和宽 hgh 必须为 8 的倍数 uchar i,j; /这里行 posx 如果不取 8 的倍数，则要另外算 hgh =hgh/8; for(i = 0; i < hgh; i+ if(posy < 64 / lcd_cmd_wr(0xb8+posx+i,0; /汉字的上半部份,相当于图片占用的第一个 汉字的上半 ,加指明是在 LCD 的左,; lcd_cmd_wr(0x40+posy,0; / 下半部 份,. . for(j = 0; j < wth;j+ lcd_data_wr(bmp32*i+j,0; /相当于开个汉字进行扫描的一行,这时两个代 码

4、才是一个点阵的一行,不是一行汉字 else lcd_cmd_wr(0xb8+posx+i,1; lcd_cmd_wr(0x40+posy-64,1; for(j = 0; j < wth; j+ lcd_data_wr(bmp32*i+j,1; void lcd_rol( /向上滚屏 uchar i; for(i = 0; i < 64; i+ lcd_cmd_wr(0xc0+i,0; / 只要 D7 是高电平,就可以了,b0 和 c0 都是一样的. lcd_cmd_wr(0xc0+i,1; delay(8; void lcd_clear( uchar i,j; for(i=0;i
