作为avr最小系统的测试程序,所有IO口都发光(As avr minimum system testing procedures, all the IO ports are luminous)

MSP430单片机C语言应用程序设计实例精讲(MSP430 microcontroller C language application design example succinctly)

5KW 逆变电源原理图。可以直接做PCB(5KW power inverter schematic. Can directly do the PCB)

以上是二维傅里叶变换程序源代码 还有傅里叶反变换(These are the two-dimensional Fourier Transform source code for inverse Fourier transform)

采用NI公司的PCI-6224多功能数据采集(DAQ)板卡并基于图形化的LabVIEW进行编程，设计了多通道数据采集与显示系统。该系统可通过完整的人机交互界面进行试验参数设置和功能选择，并可对数据采集卡上传的数据进行实时显示和处理，并具有数据存储、回放及波形重新显示功能。(This paper employs the NI PCI-6224, a multifunctional data acquisition (DAQ) board , a multi-channel data acquisition and display system based on graphical LabVIEW is presented . The system can achieve parameter reset and function redefine by the complete man-machine interface, it can real-time display and process the data DAQ , board, it can save and replay the data, redisplay the waveform as well .)

包含ads1*9*和msp430这一类心电采集芯片的所有代码函数（所有代码都是基于msp430单片机开发的）(Contains ads1*9* and msp430 this kind of ecg acquisition chip all the code functions (all code was developed based on msp430 single chip microcomputer))

利用51单片机开发一个超声波测距仪，精确度0.5mm，测量距离5—7米。(The use of an ultrasonic range finder 51 MCU development, the accuracy of 0.5mm, measure the distance 5-7 meters.)

esp8266测试源码,测试STA和AP功能。并且对TCP,UDP测试（来自原子）。(Esp8266 test source code, testing STA and AP functions. And for TCP, UDP tests ( atoms).)

说明：  下面的程序利用友元函数求两点间的距离。请你将有关的程序补充完整，并总结为什么这里要用友元函数来求两点间的距离。(using friend to get the result.)
