外国人开发的单片机网络资料，包含原理图，PCB图，调试程序，就是语言比较难懂，给大家看看作为参考吧-foreigners development of the single-chip microcomputer network information, including drawings, PCB plans, debugging procedures, Language is more difficult, for everyone to look at it as a reference

一线总线”数字化温度传感器是DALLAS最新单线数字温度传感器， 同DS1820一样，DS18B20也 支持“一线总线”接口，测量温度范围为 -55°C~+125°C，在-10~+85°C范围内,精度为±0.5°C。DS1822的精度较差为± 2°C 。现场温度直-Bus line " digital temperature sensors are single-DALLAS latest digital temperature sensor, with the DS1820, as, DS18B20 also supports" bus line " interface, measurement temperature range of-55 ° C ~+125 ° C, at-10 ~+85 ° C range, the accuracy of ± 0.5 ° C. DS1822 relatively poor for the accuracy of ± 2 ° C. scene straight temperature

一个基于单片机的充电器程序，能冲各种电池，可以设定模式。-A procedure based on single chip charger can be washed all kinds of batteries, you can set the mode.

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
