nrf2401功能使用文档，对学习者很有帮助。(zidongfanyi chu wenti le ,zhineng xie pingyin le.)

这是一个在万能充电器中能自动识别电池极性的电路图，非常巧妙的设计(This is a universal battery charger can automatically identify the polarity of the circuit, very clever design)

飞思卡尔的风单片机源程序，希望有帮助哦，记得好好刊登在用看(Freescale wind microcontroller source code, hope helpful Oh, I remember the good published in see)

用89C51单片机控制的直流电机C语言程序，程序简单有中文解释！(89C51 microcontroller with the control of DC motor C language program, the program simple to explain in Chinese!)

STM32外扩4*4矩阵键盘，包含原理图及源码。(STM32 extends 4*4 matrix keyboard, including schematic diagram and source code.)

一调试好了，放心使用吧，很好的，保证你会满意的。(A debugging good, feel free to use, very good, guarantee that you will be satisfied.)

说明：  基于MSP430F5438A的AD9854驱动，AD9854的DDS核具有48位的频率分辨率（在300M系统时钟下，频率分辨率可达1uHZ）。输出17位相位截断保证了良好的无杂散动态范围指标。AD9854允许输出的信号频率高达150MHZ(Based on the AD9854 driver of MSP430F5438A, the DDS core of AD9854 has a frequency resolution of 48 bits (up to uHZ at 300 M system clock). Output 17-bit phase truncation ensures a good dynamic range index without spurious. AD9854 permits up to 150 MHZ of output signal frequency)

用键盘控制数码管，控制数码管进行静态显示，所有的数码管都显示同样的数字(With the keyboard control digital tube, digital tube display, static control all digital tube display the same number)

温湿度检测 AM32101温湿度传感器 可以检测(Temperature and humidity sensor temperature and humidity testing AM32101)

这是基于开发板LPC1114的源码程序，是用C语言编写，用于实现LED灯的点亮以及开关的控制，同时它也是一个完整的模板，可以在此基础上添加其他程序用于开发板的学习，是一个完整的模板，可直接使用。(This is based on the development board LPC1114 source code program, is written in C language, used to realize the lighting of LED lights and switch control, at the same time, it is also a complete template, you can add other programs on this basis for the development board learning, is a complete template, can be used directly.)
