这是运用MSP430单片机 对键盘进行判别的程序 运用单片机引脚的中断功能 使得只用一次扫描就可以 识别键盘码 -This the use of the keyboard MSP430 the procedures for identifying the microcomputer-pin interrupted feature allows only one scan can be identified keyboard code

DIY多功能转换器（已调试通过）。 本原理图可以实现USB/RS232、USB/RS422、USB/RS485接口转换功能。只需安装USB驱动程序即可实现USB转串口的功能，简单方便。另外只需对电路图稍作改动即可实现RS232/RS422或RS232/RS485转换功能。 心动了吗？不如赶快行动，拥有属于自己的五合一的接口转换器吧！-DIY Multi-function Converter (has debug through). The schematic diagram can be achieved USB/RS232, USB/RS422, USB/RS485 interface conversion. Simply install the USB driver can achieve the function of USB to serial, easy and convenient. Also just to make a minor amendment to the circuit can be realized RS232/RS422 or RS232/RS485 conversion. Echocardiography it? Action as soon as possible, with their own-one interface converter吧!

MCS51外部中断1和定时器T0的应用，外部中断1连接一个按键，通过调节按键改变定时器的值，定时器输出连接一个蜂鸣器-MCS51 and one external interrupt timer T0 applications, external interrupt 1 to connect a button, through the adjustment button to change the timer value, the timer output to connect a buzzer

设计使得原本需要14个IO接口的键盘显示少用了9个单片机IO接口,虽然该设计的优势在本实验中没有完全体现出来,但若在现代工业设计中应用此方案,在对引脚需要较大的产品中其优点将体现得淋漓尽致。.-Design makes the original needs 14 IO interface shows the use of a keyboard 9 Singlechip IO interface, although the advantages of the design in this experiment did not fully reflected, but in modern industrial design in the application of this program in the pairs of primers Products feet larger in its merits and will be reflected most vividly. .
