128X64 LCD 驱动程序 C51-the built C51 LCD Driver

利用C8051f350制作的一个高精度AD采集系统，本实例应用与油中含水检测！-C8051f350 produced using a high-precision AD acquisition system, the instances of application and the oil water testing!

完成了802.15.4协议中MAC层的工作，其主要功能就是完成了透明的无线传输-Completed the MAC layer in 802.15.4 work, its main function is completed transparent wireless transmission

ok!The program is very good!

80c51与ISD4003应用程序，功能挺好的，我希望大家喜欢吧-80C51 with ISD4003 applications, features very good, and I hope everyone likes it

单片机和GPRS通信模块的开发思路，详细描述了GPRS组网过程。

这是一个1602液晶的显示程序，基于51单片机，已实验成功-This is a 1602 LCD display procedures, based on 51 single-chip, has conducted successful experiments in

void InitGoertzel(void) 作用：初始化算法参数 用法：采用算法进行检测前执行一次，如果需要改变参数，调用SetParameter() float CGoertzel::GetMagnitude(unsigned char * sampleData, int length) //算法主接口 作用：对采集下来的音频数据用算法处理，返回一个结果 参数：sampleData－音频数据缓冲地址指针； length-缓冲区尺寸(音频数据数量),字节数； 返回值：返回算法结果。 void SetParameter(DWORD set_SampleRate, DWORD set_TargetFreq, DWORD set_BlockSize) 作用：设置算法参数； 参数：set_SampleRate-音频数据抽样速率； set_TargetFreq-目标信号频率； set_BlockSize－算法数据块尺寸(采样点)； 用法：调用本函数后，需要调用一次InitGoertzel(void)才会生效-void InitGoertzel (void) function: initialization algorithm parameters Usage: The algorithm performs a pre-test, if the need to change the parameters, calling SetParameter () float CGoertzel:: GetMagnitude (unsigned char* sampleData, int length)// Algorithm for the main interface role: to collect audio data from the treatment algorithm to return a result parameter: sampleData-audio data buffer address pointer length-buffer size (the number of audio data), number of bytes return value: the return of

该源码是基于atmel公司的89C51SND1C的mp3解决方案，支持三星和东芝的NAND flash 上的fat12，fat16和fat32文件系统。-the source is based on the ATMEL 89C51SND1C mp3 solution that supports Samsung and Toshiba"s NAND flash on the FAT12, fat16 and fat32 file system.
