Description: 实现pc机键盘（p/s2接口）与8位单片机连接使用
原理：键盘时钟接在p3.2口，既8051的外部中断int0上，键盘数据接到p1.0上
每次按键，键盘会向单片机发脉冲使单片机发生外部中断，数据有p1.0口一位一位传进来
传回的数据格式为：1位开始位（0），8位数据位（所按按键的通码，用来识别按键），1位校验位(奇校验)
1位结束位(1)
实现：将键盘发回的数据放到一个缓冲区里（数组），当按键结束后发生内部中断来处理所按的按键
缺点：由于51单片机的容量有限所以缓冲区不可以开的太大，这就导致可以记录键盘的按键次数过少，
也就是容错性一般。不过如果正常使用键盘是不会出错的

描述：利用已有CAN TEST V1.0电路板进行调试,
可靠性测试已通过，并发现8515外部中断不稳定
的原因是没有在INT0脚加上拉电阻，加上后已能
够稳定地运行
调试过程中发现SJA1000的首地址设置有误，改过
后，当CAN发送数据时，程序能进入中断了，但发现
中断是由出错报警中断引起的，估计与波特率设置
有关。
通过修改CDR的参数，以及更换16M晶振，现在已能
正常地收发送数据了-MCU : ATMEGA8515 Frequence : 16M Description : make use of the existing CAN TEST V1.0 circuit board debugging and reliability tests were passed, 8515 and found that the external interrupt instability is not in INT0 feet with pull-up resistors. after adding stability to the running debug process SJA1000 found in the first set addresses wrong, to turn over, When CAN send data, the program can enter the interruption, but the interruption was discovered by police errors arising from the interruption, estimates and baud rate settings. CDR by modifying the parameters, and the replacement of 16M crystal, it is now normal to send data admission!

Description: 一些应用中，经常要用到双串口，但是一般单片机只提供一个串口，其实完全可以用普通I/O口模拟一个串口。以下的程序是我编写的模拟串口程序，程序中使用了单片机的定时器0，和INT0中断。数据的发送和接收由中断程序自动进行。程序已经过AVR仿真器仿真和实际烧片使用，证明可靠。有一点需要说明的是，此模拟的串口为半双工方式。
主程序中，单片机将标准串口设置为115200bps,将模拟串口设置为19200bps。单片机将标准串口收到的数据从模拟串口发送出去，将模拟串口接收到的数据从标准串口发送回来。-some applications, the regular use of the dual serial port, but most only provide a microcontroller serial, In fact, the general can use I / O simulation of a serial mouth. Following the procedure is that I serial simulation procedure is the use of the computer's timer 0, and INT0 interruption. Data sending and receiving process by automatically suspended. Procedures have been AVR Simulator simulation and actual use of burn unit proved reliable. It should be explained that this simulation of half-duplex serial port. Main program, SCM standard serial port set to 115,200 bps. Serial analog set to 19,200 bps. SCM standard serial data received from analog to serial sent, Serial analog to receive data from the standard serial sent back.
