AT24C02串行E2PROM的工作原理与读写(AT24C02 E2PROM read & write)

适用于gps、北斗等通用GPS串口数据解析，适用于linux端，经、纬度，时间、搜星数、速度、角度等信息，采用select机制，优化系统资源，提高读取写入效率。

说明：  由于不满意语音芯片的复制性差，于是自己做了一个语言模块，用STC12LE2052单片机的PWM功能播放声音，从Wave文件中提取的声音数据通过串口从计算机下载，存储在串行Flash芯片SST25VF016B中，可进行单段播放和循环播放，单个模块的制作成本应该在30元以下，可以播8K8位的声音256秒。(Not satisfied with the voice chip, as a result of poor copy, so do a language module, with the STC' s 2052 single-chip PWM function to play a sound, from the Wave files to extract the audio data downloaded from the computer through the serial port, is stored in the Serial Flash chip, can play single player and recycling, the production costs of a single module should be below 30, you can broadcast the voice of 8K8-bit 256 seconds.)

Path manually writing code, is to allow the ns2 manual routing is used, this is our experimental multichannel implementation, hoping to share.

CRC校验,完成Crc校验 CRC check, complete Crc check()

说明：  这个是M128单片机的一些程序和proteus的例程(this is somet about danpianji)

51单片机使用KEill编写，控制蜂鸣器发声，定时器为16位

说明：  基于VC++的51单片机控制源码，PC与单片机双向通讯智能温控程序(Based on VC ++ 51 single-chip microcomputer control source code, PC and single-chip bidirectional communication intelligent temperature control program)

有不同重量的物品n件，求从这n件物品中任取一部分物品放入背包，使选中的物品的总重量不超过指定的限制重量，但选中物品的价值之合为最大。即任意给定物品个数及它们的重量和价值，在最大的限制重量一定的情况下，为了使价值最大，选出最优解。(There are different weights of items n pieces from n items in order to obtain any portion of the goods into the backpack, so that the total weight of the selected items does not exceed the specified weight limit, but the combined value of selected items as the greatest. That any given number of items and their weight and value limits the maximum weight of certain circumstances, in order to value the most, select the optimal solution.)
