贪吃蛇Ｃ源码，可以实现Ｃ语言的一个游戏．-code of a game named eat_snake,this is can carry out a game of c language

Abstract A new intelligent milometer base on a microcontroller can count the sum. By taking full use of the processor 89s51 and E² PROM (AT24C02) and sensor of magnetism, it can count the sum of fully distance and the course of development.

自己做的4×4键盘扫描，加入了按下消抖动，松开输入数据的简单功能。-Do their own 4 × 4 keyboard scanning, joined the press extinction jitter, release a simple function of the input data.

8259A中断控制器实验 253A的计数器0为工作方式0，装入时间常数FFFFH，结束中断时显示信息：8253A INTERRUPT EXPERIMENT！-8259A interrupt controller experimental 253A of counter 0 0 way to work, the time constant FFFFH loaded to end disruption to display information : 8253A INTERRUPT EXPERIMENT!

汇编语言的另一个打字游戏 比较好 测试通过masm6.0-Assembly language of another typing test game better masm6.0

从键盘读入一个四位的十六进制数，CRT显示等值的二进制数. 由于每个十六进制数位对应4个二进制，所以每读入一个十六进制位后，即可将其对应的4个二进制位依次输出。由于数字‘０’~ ‘９’的ASCⅡ码为30H～39H,字母‘a’～‘f’与 ‘A’～‘F’的ASCⅡ码为61H～66H 与41H～46H ，因此，如果输入的字母为数字‘０’～‘９’，则其低４位即为对应的二进制位；如果输入的字符为字母‘ａ’～‘ｆ’或‘Ａ’～‘Ｆ’，则需要减７，然后通过移位将低４位依次输出。 -Reading from the keyboard into a 4 hexadecimal number, CRT display equivalent binary number. Since each hexadecimal number of the corresponding 4-bit binary, so every time into a hexadecimal places, can be its corresponding 4-bit binary sequence output. Due to the number

开始时，显示“00”，第1次按下SP1后就开始计时。 第2次按SP1后，计时停止。 第3次按SP1后，计时归零。 -Beginning to show 00 , 1st press SP1 after the beginning of time. 2nd by SP1, the time to stop. The 3rd by SP1, the time zero.

基于51单片机的带时间显示和紧急控制的交通灯的设计。 此程序在硬件上调试通，用定时器1延时，外部中断0接紧急控制，R0为100MS延时常数，R2为状态延时常数，8279控制数码管显示时间,用P1口控制双色灯-With 51 single-chip based on the time display and the emergency control of traffic lights design. On this process in hardware debugging pass, with one delay timer, external interrupt 0 then the emergency control, R0 for 100MS constant delay, R2 for a state of constant delay, digital 8279 control display time control using two-color lights I P1
