TMS320lf2047a的经典异步串行通信程序好得很-TMS320lf2047a classic asynchronous serial communication program very good

USE DS18B20 IN P16F877A

主要用于LCD的驱动,还有一些关于它的资料,等以后再传上来,它是驱动128*64大小的LCD,相当有用,也相当有价值,使用起也很简单!-mainly used for LCD driver, and some information about it, such as after a tame onto, it is 128* 64-size LCD, very useful and very valuable, since use is also very simple!

本例在设计时采用了ADO.net访问数据库的技术，前台用VB.net2008作为开发工具，后台数据库采用了SQL server2005，然后通过前台对各项数据进行日常操作-In this case were used in the design of ADO.net database access technology, the future use VB.net2008 as development tools, back-end database using SQL server2005, and then through the front of the data on day-to-day operation

用汇编语言实现人名排序问题,根据字母的顺序排列,先比较首字母,如果相同则比较之后的字母-using assembly language to achieve names scheduling problem, according to the alphabetical order, compare the first letters of the alphabet, If the same comparison is the after letters

PWM 控制 LED 灯渐亮渐灭程序 适用 ME300B 开发系统 利用定时器控制产生占空比可变的 PWM 波 按K1，PWM值增加，则占空比减小,LED 灯渐暗。 按K2，PWM值减小，则占空比增加,LED 灯渐亮。 当PWM值增加到最大值或减小到最小值时，蜂鸣器将报警。-PWM control of LED lights getting brighter gradually eliminate procedures apply ME300B development system the use of timer control which produces a variable duty cycle PWM wave by K1, PWM value is increased, then the duty cycle decreases, LED lights dimming. According to K2, PWM value is reduced, then the duty cycle increases, LED lights gradually brighter. When the PWM value is increased to maximum or reduced to minimum, the buzzer will alarm.

8051核的DES源代码 使用C语言写的基于51核的DES原码，变量定义使用汇编。占用了130字节RAM，比我所见到的包括汇编编写的都要快。 -8051 nuclear DES use source code written in C language based on the 51 nuclear DES original code, the use of variable definition compilation. Occupy the 130 byte RAM, than I have seen in the preparation of the compilation must fast.
