用汇编语言写的生日快乐-using assembly language to write a happy birthday

本系统以AT89S52单片机为核心部件，外加温度采集电路、及显示电路和越限报警等电路。采用单总线型数字式的温度传感器DS18B20，使系统具有测温误差小、分辨率高、抗干扰能力强，动态显示的方式等特点。本设计既可以对当前温度进行检测又可以对温度进行数码显示，两位整数两位小数的显示方式具有更高的显示精度，若超越极限温度则触发蜂鸣器报警。利用功能强大的Keil和具有互动电路仿真的Proteus进行程序的编写和仿真。-The system AT89S52 microcontroller as its core components, plus the temperature acquisition circuit, and display circuitry, and the more limited alarm circuits. Single bus-type digital temperature sensor DS18B20, the system has a temperature measurement error of the small, high resolution, anti-interference ability, dynamic show the way and so on. This design not only can detect the current temperature can also right temperature digital display, two integers with two decimal places are displayed to show a higher precision, if the temperature is beyond the limits of buzzer alarm is triggered. Keil and the use of powerful interactive circuit simulation of the Proteus programming the preparation and simulation.

用8251实现串行口异步通信，自发自收，波特率1200bps。采用查询方式发送与接收。从键盘输入发送字符。发送与接收的字符均在屏幕上显示。按esc键返回dos-Achieved with the 8251 serial asynchronous communication, spontaneous self-income, the baud rate 1200bps. Way to send and receive using queries. To send characters from the keyboard. Send and receive characters are displayed on the screen. Press esc key to return to dos

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

如何使用批处理文件（也被称为批处理程序或脚本）-How to use the batch file (also known as a batch program or script)

AT89S51的并行口P1接4×4矩阵键盘，以P1.0－P1.3作输入线，以P1.4－P1.7作输出线；在数码管上显示每个按键的“0－F”序号。-AT89S51 the parallel port P1 then 4 × 4 matrix keyboard to P1.0-P1.3 as input lines to P1.4-P1.7 for output line in the digital control button displayed on each of the " 0-F" serial 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.
