μC/GUI 是一种用于嵌入式应用的图形支持软件。它被设计用于为任何使用一个图形LCD 的应用提供一个有效的不依赖于处理器和LCD 控制器的图形用户接口。它能工作于单任务或 多任务的系统环境下。μC/GUI 适用于使用任何LCD 控制和CPU 的任何尺寸的物理和虚拟显示。 它的设计是模块化的，由在不同的模块中的不同的层组成。一个层，称作LCD 驱动程序，包 含了对LCD 的全部访问。μC/GUI 适用于所有的CPU，因为它100 由的ANSI 的C 语言编写的。(μC/GUI is a graphical support software for embedded applications. It is designed to provide an effective does not rely on a graphical user interface of the processor and an LCD controller of any use of the application of a graphic LCD. The system can work on a single task or multiple tasks environment. μC/GUI for any LCD controller and CPU of any size physical and virtual display. Its design is modular, composed of different layers in different modules. A layer, called the LCD driver, including full access to the LCD. μC/GUI applies to all of the CPU, because it is 100 written in ANSI C language.)

STM8S运行LED程序和讲义 流水灯是单片机初学者入门首先学习的一个例程，其作用与地位就如同学习 编程语言时学写“Hello，World”程序一样。流水灯例程的编写就是对 I/O 口的 简单操作， 当知道怎么点亮一盏 Led 灯的时候，恭喜你，你已经能够简单地控制 一款芯片了！(STM8S running water lights LED program and handouts are microcontroller beginners first learn a routine, its role and position is like learning to write to learn programming language " Hello, World" program like. Light water routine is to write I/O port of a simple operation, when you know how lit a Led lamps, congratulations, you have been able to easily control a chip up!)

谐波抑制的一个重要趋势是采用有源电力滤波器，有源电力滤波器也是一种电力电子装置，且相关技术的研究也日渐成为研究的热点。本文阐述了几种常见APF的拓扑结构及各自的优缺点，详细分析了基于瞬时无功功率理论的谐波检测方法，比例控制和前馈控制两种电流环控制策略以及SPWM和SVPWM两种调制策略。(the harmonic suppression is an important trend of active power filters, active power filter is a power electronic devices, and related technologies are increasingly become a hot topic. This paper describes the topology and their advantages and disadvantages of several common APF, a detailed analysis of the harmonic detection method based on instantaneous reactive power theory, and proportional control and feedforward control of)

这是一个有关AD7689的程序，只有驱动部分，使用的CPU是msp430F149。可以采集8路数据。不过数据在主程序中需要处理下，不然会有波动。(This is a program about the AD7689, only the driving part, CPU use is msp430F149. 8-way data can be collected. However, the data need to be addressed in the main program, the otherwise subject to fluctuations.)

利用单片机MSP430f149单片机实现的 实验十二 SPI接口扩展RF通信(The use of single-chip MCU MSP430f149 Experiment 12 SPI interface extensions RF communications)

步进电机28BYJ48型四相八拍电机，电压为DC5V—DC12V。当对步进电机施加一系列连续不断的控制脉冲时，它可以连续不断地转动。每一个脉冲信号对应步进电机的某一相或两相绕组的通电状态改变一次，也就对应转子转过一定的角度（一个步距角）。当通电状态的改变完成一个循环时，转子转过一个齿距。四相步进电机可以在不同的通电方式下运行，常见的通电方式有单（单相绕组通电）四拍（A-B-C-D-A。。。），双（双相绕组通电）四拍（AB-BC-CD-DA-AB-。。。），八拍（A-AB-B-BC-C-CD-D-DA-A。。。）(Stepping Motor 28BYJ48 four-phase eight-phase motor, the voltage DC5V-DC12V. When a series of continuous control pulses are applied to the stepper motor, it can be continuously rotated. Each pulse signal corresponds to the stepper motor of a phase or two-phase winding power state change once, also corresponds to the rotor through a certain angle (a step angle). When the change in the power-on state completes one cycle, the rotor turns one pitch. Four-phase stepper motors can be operated in different power-up modes. The common power-up modes are: single-phase winding power (ABCDA ...), double (dual-phase winding)-DA-AB-...), eight beats (A-AB-B-BC-C-CD-)
