Haskell---The-Craft-of-Functional-Programming--2e

基于stm32f103系列的直接内存存储方式的多种波形发生器，能产生正弦波、方波、三角波、锯齿波、T形波，其频率幅度可调(Based stm32f103 series of direct memory storage of a variety of waveform generator can produce sine, square, triangle wave, sawtooth wave, T-wave, the frequency amplitude adjustable)

说明：  AD模数转换，基础lcd1602显示屏。。。。。。(AD analog-to-digital conversion, basic LCD 1602 display screen...)

PWM调光 1、学习目的：利用定时器产生PWM，了解原理和使用方法 2、硬件要求：LED灯 定时器 3、试验现象：LED灯由亮到灭，由灭到亮逐步变化，也就是调光现象(PWM dimming, learning objectives: the use of the timer to generate PWM understand the principles and use hardware requirements: LED lamp timer test phenomenon: LED lights from bright to off, gradually changes from off to bright, that is, adjusted optical phenomena)

介绍单相全桥逆变器的工作原理, 阐述产生SPWM波和实现PI 控制的算法, 给出以DSP( 数 字信号处理器) 实现控制的软件流程。实验表明利用软件完成逆变器控制是可行的。 关键词: 正弦逆变器 (Introduction of single-phase full-bridge inverter working principle, the resulting SPWM wave and realize PI control algorithm to DSP (digital signal processors) to achieve software flow control. Experiments show that the use of software controlled inverter is feasible. Key words: sine inverter)

Msp430F149 串口UART例程，测试通过，完美无BUG(Msp430F149 serial UART routines, tested, Perfect BUG)

说明：  51的贪吃蛇小游戏，没什么算法，多看就明白了(51 Snake Eating Game, there is no algorithm, you can see more clearly.)

MC9S12XEP100 PLL时钟配置例程(MC9S12XEP100 PLL setup)

此源码为c#编写的pc上位机程序，通过串口实现对3路步进电机的控制，可选择电机使能，正反转，转动角度，细分数等(This source code is written in c# program pc PC through the serial interface on the 3-way stepping motor control, motor option is enabled, rotating, rotation angle, and number of segments)

使用protuce对直流电机进行仿真，仿真程序在压缩文件里(Using protuce to simulate DC moto)

该压缩包主要包含Freescale单片机HCS08DZ系列的各外设DEMO程序，对初次接触该系列单片机的初学者来讲很有借鉴意义。(The archive consists mainly of Freescale microcontroller peripherals DEMO HCS08DZ series of each program, the initial contact with the family of microcontrollers for beginners in terms of referential significance。)
