C51的一些误区和注意事项（ZT） 1)C忌讳绝对定位。 常看见初学者要求使用_at_,这是一种谬误，把C当作ASM看待了。在C中变量 的定位是编译器的事情，初学者只要定义变量和变量的作 用域，编译器就把一个固定地址给这个 变量。怎么取得这个变量的地址？要用指针。比如unsigned char data x 后，x的地址就是... -C51 some errors and attention to the business (ZT) 1) C taboo absolute positioning. See beginners often require the use of _at_, this is a fallacy, ASM C as a treat. C variables in the positioning of the compiler things, as long as the definition of beginners variable and the variable scope, Compiler put a fixed address to this variable. How the variables made the address? Use indicators. Unsigned char data such as x, x is the address ...

在当今,流行的编程软件种类繁多，它们编程方便、易于维护，但是在与硬件直接打交道和编制系统软件时却束手无策，于是C语言就有了用武之地。C语言作为汇编语言与高级语言之间的一种过渡语言，兼有汇编语言的高效和高级语言的方便。 　　在通讯中，为了保证行运安全可靠，标准的串行口必须具有许多握手信号和状态信息。这是因为通讯的各个计算机CPU速度不一样（这会导致“错帧”）以及发送机发送数据速度比接收机接收速度快（这会导致“过冲”）。为解决这个问题，我们采用一个简单的握手信号，即发送机每次仅发送半个字节（低4位）的数据，而另外半个字节（高4位）则用来传送信息。我们可以对信息位（高4位）进行如下简单的编码：-today, the popularity of the wide variety of software programming, is easy to maintain, but to deal directly with the hardware and system software when compiled a loss, so there will be a C language battlefield. C language as the compilation and Advanced Language a transition between languages, both assembly language and the efficient high-level language convenience. In telecommunications, in order to ensure safe and reliable transport firms, the standard serial I must have shook hands with many signals and state information. This is because the various computer communications CPU speed is not the same (this would lead to "the wrong frame") and transmitter to send data faster than fa

本程序用于测试实时时钟模块SD2000系列功能之一:四种中断功能 程序功能如下： 1.在SD2000试验板上显示实时时间的小时和分钟? 2./INT1 到指定时刻时输出低电平. 3./INT2输出固定频率32768HZ. 4.测试每分钟边沿中断输出(INT MODE3)和每分钟固定中断输出(INT MODE4)功能-procedures used to test the real-time clock module SD2000 series of functional one : four interrupts functions of the program are as follows : 1. The SD2000 board real-time test of time 2./INT1 hours and minutes to the designated low-level output at the moment. 3./INT2 32768HZ fixed frequency output. 4. testing every minute edge interrupt output (INT MODE3) per minute and fixed interrupt output (INT MODE4) function

内核超时等待机制的原理: 应用程序通过操作系统提供的系统调用接口获取资源时，在系统调用的入口参数里可以指定超时等待的最大时间，通常以毫秒为单位，内核会将其转化为系统的时钟（tick） -Timeout waiting for core principles of mechanism: the application through the operating system
