静止/旋转显示的流程图:开始外部中断0中断定时1中断计算实际地址与参考地址的相对地址地址归0，并根据中断的次数调整定时器1的中断时间如果按下了旋转键，参考地址加1地址加1根据预先规定的在相应的地址循环显示时间设置时间的流程图：开始接受到遥控信息，触发外部中断1，记录每次中断时间，产生33次中断后结束接收完标志置0为加键，根据右键的指示相应位加为右键，年月日时分秒之间切换接收完标志置1接收完标志是否为1判断键位 是否循环显示时间旋转led控制代码：用到了遥控接收头控制显示画面，红外对管来控制转速。能够显示数字时钟，24个字符和各种标点符号，能够显示数字时钟，可以用遥控修改时间，切换显示，改变画面旋转的速度。#include#include#define uchar unsigned char#define uint unsigned int#define Width 14/一个字符宽度#define CodeEN 0x09/确定键#define CodeUP 0x15/加键#define CodeRight 0x40/右键#define CodeRoll 0x43/旋转#define CodeYT 0x47/时间和日期切换#define CodeSpeed 0x0d/速度#define NumFunc 4/功能数目#define NumCharChange 3/最多3位数字可调#define NumXLab 180/横坐标范围(0-179)/#define FlagSan 3/用于控制闪烁/*/*红外部分*uchar irtime=0;/用来解码计时uchar irdatatime8;/8位用户码编码时间uchar irnum=0;/数据位数uchar irdata;bit recok=0;/接收完成标志bit conok=0;/转换完成标志/*/*按键部分*bit keydown=0;/响应按键标志bit numkeyen=0;/确定键按下次数,功能选择游标,0为初始画面uchar numkeyright=0;/右键按下的次数,字符调整游标uchar flagyt=0;/时间和日期切换,0为时间,1为日期,2为星期/*/*时间部分*uint timecount=0;/标准时间计时uchar year=11,month=6,date=4,week=6;/0为星期日,1为星期1uchar hour=9,minite=0,second=0;/时分秒uchar weeka=31,weekb=12,weekc=30;/装星期的字符/*/*显示部分*uint xlab=0;/横坐标uint Tfstvlue=65236;/64936;/定时器时间,用来调整显示uchar begindisp=0;/开始显示的地址uchar speed=0;/转速bit flag=0;/闪烁控制bit stoptimer=1;/0表示时间停止走动bit flagroll=0;/控制旋转/*/*字符编码* uchar code charcodeWidth=0xc0,0xc0,0xde,0xde,0xde,0xde,0xde,0xde,0xde,0xc0,0xc0,0xff,0xff,0xff,/00xff,0xc0,0xc0,0xc0,0xc0,0xc0,0xc0,0xdf,0xdf,0xff,0xff,0xff,0xff,0xff,/10xc2,0xc2,0xda,0xda,0xda,0xda,0xda,0xda,0xda,0xd8,0xd8,0xff,0xff,0xff,/20xc0,0xc0,0xda,0xda,0xda,0xda,0xda,0xda,0xda,0xda,0xda,0xff,0xff,0xff,/30xfb,0xfb,0xfb,0xc0,0xc0,0xfb,0xfb,0xfb,0xfb,0xc3,0xc3,0xff,0xff,0xff,/40xd0,0xd0,0xd6,0xd6,0xd6,0xd6,0xd6,0xd6,0xd6,0xc6,0xc6,0xff,0xff,0xff,/50xd8,0xd8,0xda,0xda,0xda,0xda,0xda,0xda,0xda,0xc0,0xc0,0xff,0xff,0xff,/60xcf,0xc7,0xd7,0xd3,0xdb,0xd9,0xdc,0xdc,0xde,0xdf,0xdf,0xff,0xff,0xff,/70xc0,0xc0,0xda,0xda,0xda,0xda,0xda,0xda,0xda,0xc0,0xc0,0xff,0xff,0xff,/80xc0,0xc0,0xd6,0xd6,0xd6,0xd6,0xd6,0xd6,0xd6,0xc6,0xc6,0xff,0xff,0xff,/90xdf,0xdf,0xcf,0xef,0xe7,0xf7,0xf3,0xfb,0xf9,0xfd,0xfc,0xfe,0xfe,0xff,/,100xff,0xff,0xff,0xed,0xed,0xed,0xed,0xed,0xef,0xff,0xff,0xff,0xff,0xff,/:,110xe0,0xc0,0xd7,0xd7,0xd7,0xd7,0xd7,0xd7,0xd7,0xc0,0xe0,0xff,0xff,0xff,/a,120xe5,0xc0,0xda,0xda,0xda,0xda,0xda,0xda,0xda,0xc0,0xc0,0xff,0xff,0xff,/b,130xde,0xde,0xde,0xde,0xde,0xde,0xde,0xde,0xde,0xc0,0xc0,0xff,0xff,0xff,/c,140xf1,0xe0,0xce,0xde,0xde,0xde,0xde,0xde,0xde,0xc0,0xc0,0xff,0xff,0xff,/d,150xda,0xda,0xda,0xda,0xda,0xda,0xda,0xda,0xda,0xc0,0xc0,0xff,0xff,0xff,/e,160xdb,0xdb,0xdb,0xdb,0xdb,0xdb,0xdb,0xdb,0xdb,0xc0,0xc0,0xff,0xff,0xff,/f,170xdb,0xdb,0xd8,0xd8,0xda,0xda,0xde,0xde,0xde,0xc0,0xc0,0xff,0xff,0xff,/g,180xc0,0xc0,0xfb,0xfb,0xfb,0xfb,0xfb,0xfb,0xfb,0xc0,0xc0,0xff,0xff,0xff,/h,190xff,0xff,0xff,0xde,0xc0,0xc0,0xde,0xff,0xff,0xff,0xff,0xff,0xff,0xff,/i,200xdf,0xcf,0xc7,0xd3,0xf9,0xfc,0xfe,0xfe,0xfc,0xf9,0xfb,0xff,0xff,0xff,/j,210xff,0xde,0xde,0xce,0xec,0xe5,0xf1,0xfb,0xfb,0xc0,0xc0,0xff,0xff,0xff,/k,220xff,0xff,0xfe,0xfe,0xfe,0xfe,0xc0,0xc0,0xff,0xff,0xff,0xff,0xff,0xff,/l,230xc0,0xc0,0xdf,0xdf,0xdf,0xc0,0xdf,0xdf,0xdf,0xc0,0xc0,0xff,0xff,0xff,/m,240xc0,0xc0,0xfe,0xfc,0xf9,0xf3,0xe7,0xcf,0xc0,0xc0,0xff,0xff,0xff,0xff,/n,250xc0,0xc0,0xde,0xde,0xde,0xde,0xde,0xde,0xc0,0xc0,0xff,0xff,0xff,0xff,/o,260xc3,0xc3,0xdb,0xdb,0xdb,0xdb,0xdb,0xdb,0xdb,0xc0,0xc0,0xff,0xff,0xff,/p,270xc1,0xc1,0xdd,0xd8,0xd8,0xda,0xda,0xda,0xde,0xc0,0xc0,0xff,0xff,0xff,/q,280xc2,0xc2,0xda,0xd8,0xd9,0xdb,0xdb,0xdb,0xdb,0xc0,0xc0,0xff,0xff,0xff,/r,290xdd,0xd8,0xd8,0xda,0xda,0xda,0xda,0xda,0xc2,0xc2,0xe6,0xff,0xff,0xff,/s,300xdf,0xdf,0xdf,0xdf,0xdf,0xc0,0xc0,0xdf,0xdf,0xdf,0xdf,0xff,0xff,0xff,/t,310xc1,0xc0,0xfe,0xfe,0xfe,0xfe,0xfe,0xfe,0xfe,0xc0,0xc1,0xff,0xff,0xff,/u,320xdf,0xcf,0xe7,0xf3,0xf9,0xfc,0xf9,0xf3,0xe7,0xcf,0xdf,0xff,0xff,0xff,/v,330xc0,0xc0,0xfe,0xfe,0xfe,0xc0,0xfe,0xfe,0xfe,0xc0,0xc0,0xff,0xff,0xff,/w,340xde,0xde,0xcc,0xe5,0xf1,0xfb,0xf1,0xe5,0xcc,0xde,0xde,0xff,0xff,0xff,/x,350xdf,0xdf,0xcf,0xe7,0xf3,0xf8,0xf0,0xe7,0xcf,0xdf,0xdf,0xff,0xff,0xff,/y,360xce,0xce,0xc6,0xd6,0xd2,0xda,0xd8,0xdc,0xdc,0xff,0xff,0xff,0xff,0xff/z,37;
