#八个LED 心形流水灯
今天学了定时器，老师布置了和心形流水灯有关的任务，所以就来试一下。 心形流水灯，其实就是将流水灯摆成心形，再加上花样发光就行。话不多说。代码如下
#include<reg51.h> #define u8 unsigned char ; #define u16 unsigned int ; u16 ms50; u16 lednum; u16 code temp_led[]={0xFF,0xFE,0xFD,0xFB,0xF7,0xEF,0xDF,0xBF,0x7F,0xFF, 0xFF,0x7F,0xBF,0xDF,0xEF,0xF7,0xFB,0xFD,0xFE,0xFF, 0xFF,0xFE,0xFC,0xF8,0xF0,0xE0,0xC0,0x80,0x00,0xFF 0x00,0x01,0x03,0x07,0x0F,0x1F,0x3F,0x7F,0xFF,0XFF 0xFF,0x7F,0x3F,0x1F,0x0F,0x07,0x03,0x01,0x00,0XFF 0x00,0x80,0xC0,0xE0,0xF0,0xF8,0xFC,0xFE,0xFF,0XFF 0xFF,0xE7,0xDB,0xBD,0x7E,0x7E,0xBD,0xDB,0xE7,0xFF, 0xFF,0xE7,0xDB,0xBD,0x7E,0x7E,0xBD,0xDB,0xE7,0xFF, 0xFF,0xAA,0xFF,0xAA,0xFF,0xFF,0x55,0xFF,0x55,0xFF, 0xFF,0xAA,0xFF,0xAA,0xFF,0xFF,0x55,0xFF,0x55,0xFF, 0x00,0xFF,0x00,0xFF,0x00,0xFF,0x00,0xFF,0X00,0XFF }; void init_time() { TMOD=0x01; TH0=(65535-50000)/256; TL0=(65535-50000)%256; ET0=1; EA=1; TR0=1; } void inter_timer2() interrupt 1 { TH0=(65535-50000)/256; TL0=(65535-50000)%256; ms50++; if(ms50>9) { ms50=0; P1=temp_led[lednum]; lednum++; if(lednum>104) lednum=0; } } main() { init_time(); while(1) { ;} }仿真图图片如下：
