这是我给一个做射频卡的公司做的小程序，主要是将数据同时写入PRR8031芯片和数据库，包括一些数据类型转换、生成序列号等内容-This is what I do for a radio card companies do small procedures, the data is also written into the PRR8031 chips, and databases, including some data type conversion, such as serial numbers generated content

这是一段c51编的一段有关串口通讯的代码-This is a decoder for the series of the serial communications code

串行通讯的源程序，希望帮到人哦。是再LAB2000系统下实现过的-Serial communication source, hoping to help people, oh. LAB2000 system is re-realize-off

这是非常有挑战性的题目。对于用户输入的任意一个平面函数f(x)，绘制出其函数曲线。这里最关键的技术难点就是如何实现计算表达式的值。在《编译原理》和《数据结构》的书中，都有对表达式运算方法的论述。说实在的，在编译型计算机语言中实现对用户输入表达式的运算是非常困难的。需要对表达式进行扫描，去括号，按照运算符的优先级生成2叉树，然后遍历该树生成逆波兰表达式，再然后通过栈的方法进行运算。如果在表达式中再包含有函数的话......描述起来都麻烦，更不要说用程序实现了:-(-This is a very challenging issue. For user input an arbitrary planar function f (x), mapping out its function curves. Here the most critical technical problems is how to achieve calculated the value of the expression. "Compiling Principle" and "data structure," the book, have right of expression Operational discussed. Indeed, the computer language compiler to achieve expression of the user input operation is very difficult. Need to scan expression to the brackets, in accordance with the priority Operators Generation 2-ary tree, and then traverse the tree generated reverse Polish expression, and then through the stack approach to computing. If the expression again contains the function described ...... these are trouble, not to mention t
