Project how to make jtag rs232 programmator

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

串口编程,是关于多串口,多线程,有详情的说明-Serial programming is on the serial number, multithreading, the details of the note

MSComm32.ocx串口通信程序。测试时不要用虚拟串口，直接将串口2引脚与3引脚短接。-MSComm32.ocx serial communication program. Not to test with virtual serial port, serial port directly to 2-pin and 3 pin shorted.

用vb实现串口间通信,可以用来熟悉串口间传输信息的原理.-with Serial Communication, which can be used with serial transmission of information between the principle.

这是对应于atmel公司的24cxx的驱动程序，仅供参考！-This is corresponding to the ATMEL 24cxx driver for reference!

一个很不错的代码，是学习的好榜首，请大家认真学习！-a very good code is a good study the list, please seriously learning!

8052串口驱动--(包括波特率计算,以及几个内存查看的shell命令)-8052-- (including baud rate, and several memory access to the shell commands)

同样是PIC的编程文件能够供初学者掌握编程技巧，很实用-PIC is the same programming document for beginners to programming skills, practical

可以实现HDLC帧结构中的添零功能，使得信息部分不会和HDLC帧头部分混淆。-can insert zero to the hdlc frame,
