The PCD5003A is a very low power decoder and pager
controller specifically designed for use in new generation
radio pagers. The architecture of the PCD5003A allows for
flexible application in a wide variety of radio pager designs.
The PCD5003A is fully compatible with “CCIR Radio
paging Code No. 1” (also known as the POCSAG code)
operating at data rates of 512, 1200 and 2400 bits/s using
a single oscillator crystal of 76.8 kHz.
In addition to the standard POCSAG sync word the
PCD5003A is also capable of recognizing up to 4 User
Programmable Sync Words (UPSWs). This permits the
reception of both private services and POCSAG
transmissions via the same radio channel.
Used together with the Philips UAA2080 or UAA2082
paging receiver, the PCD5003A offers a highly
sophisticated, miniature solution for the radio paging
market. Control of an RF synthesizer circuit is also
provided to ease alignment and channel selection

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

this program is targeted at specific GPS receiver
本程序是针对特定GPS接收机--JAVAD公司的legacy的一个应用，用来收取标准的NMEA-1083GGA信息或JPS格式（JAVAD公司的特有GPS信息格式）的{RT，PO}信息，并统计数据大小与经历时间。本程序用VC6.0+串口控件MSComm实现，其中关于如何在数据长度不定的情况下实现数据帧的同步的方法可以借鉴到其它串口数据采集的应用之中，具备一定的实用价值-this program is targeted at specific GPS receiver-- JAVAD the legacy of an application, used to collect standard NMEA- 1083GGA information or JPS format (JAVAD company"s unique GPS information format) (RT, PO) information and statistical data on the size and duration. The procedures used VC6.0 Serial MSComm control, on how volatile the data length of the data frame synchronization method can draw on to other serial data acquisition applications, to have some practical value
