直流电机控制程序 基于ti公司 dsp tms320lf2407a 运行环境 ccs2.2 原创 虽然很简单...

伟福LAB2000单片机仿真系统直流电机控制:利用实验仪上的D/A变换电路，输出-8V至+8V电压，控制直流电机。改变输出电.压值，改变电机转速，用8255 的PB.0 读回脉冲计数，计算电机转速。在电压允许范围内，直流电机的转速随着电压的升高而加快，若加上的电压为负电压，则电机会反向旋转。本实验仪的D/A变换可输出-8V到+8V的电压，将电压经驱动后加在直流电机上，使其运转。通过单片机输出数据到D/A变换电路，控制电压的高低和正负，观察电机的旋转情况。 在电机转盘上安装一个小磁芯，用霍尔元件感应电机转速，用单片机控制8255读回感应脉冲，从而测算出电机的转速。 -err

简单的功能介绍：本软件是由，三块模块组成。一个是打字练习，一个是打字计时，一个是音乐练习。本软件解决了打字练习途中的估噪无味，提升练习效果。本游戏有4个等级,可以根据情况来选择。这个软件还改进了，判断你是否打字失败功能。如果，打字失败，还可以从来，亦可退出。打字计时，为你打字计时间，提高效率。同时，电子琴音乐，为你在无聊时，增添色彩，可以练习歌谱，提高兴趣。-Simple, functional description: This software is, three modules. 1 is a typing exercise, one is typing time, a music practice. The software solves the assessed noise typing practice tasteless way to improve practice effect. This game has four levels, you can choose depending on the circumstances. The software also improved, to determine whether you have failed typing feature. If, typing fails, you can never can quit. Typing time for your time typing dollars and improve efficiency. At the same time, organ music, for when you" re bored, add color, you can practice song sheet, interest.

在编制键盘输入程序时常常要用到一个键的扫描码或ASC码，如用到 Foxpro 的 inkey() 函数，以及用到 BIOS 的 INT 16H时，但找一个编码表不太容易，有时候找到的编码表又不全，无法查到组合键的编码，本程序就是一个随时用来显示按键的ASC码及扫描码的程序，可以用 16 进制和 10 进制同时显示一个键按下和放开的扫描码，以及ASC码，同样也支持组合键。-Keyboard input in the preparation procedures are often used to a key scan code or ASC code, such as using Foxpro

C8051的汇编驱动程序，如果能看懂会给你带来很大的好处，学习的好资料.-The driver of C8051, it will bring you very big benfit if you will read it, it is very nice.

关于打印机的一个汇编语言程序，能用，但是希望有高手能够翻译成c语言的供大家分享-On a printer assembly language procedure, can be used, but would like to have a master can be translated into the language of c for everyone to share

ST套件上0-99秒计时，比较准的！(由网友wonderfulsf提供) ST套件上0-99秒计时，比较准的！ 这是我学习PIC完成的第一个程序烧在了ST套件上不错,0-99秒计时 如果用MPLAB模拟,用stopwach计时非常准 ST套件上0-99秒表程序,根据原0-99键控程序上改写的,初学练习-ST package on time 0-99 seconds, more accurate! (Wonderfulsf provided by users) ST package on time 0-99 seconds, more accurate! This is my PIC study completed the first procedure to burn in the ST package on good ,0-99 seconds time if MPLAB simulation, with very stopwach time on quasi-ST Suite 0-99 stopwatch program, according to the original 0-99 keying procedures on rewriting, and learning exercises
