移植成功的单片机uc/os-II代码，效果很好的-Successful transplantation Singlechip uc/os-II code, the effect of good

是16*16的点阵屏滚动显示，是源码信息，用KEIL51写的，用于51单片机-Are 16* 16 dot matrix display screen scroll, are the source information, using the Writing KEIL51 for 51 MCU

以Silicon Laboratories公司C8051F230单片机为控制核心，采用16路动态扫描方式进行显示的LED大屏幕显示系统的设计方案。采用大功率三极管TIP127进行行驱动，提高了亮度。单片机通过读取外部总线数据，可实现与上位机协同工作，也可以脱离上位机独立工作。高速的单片机系统可显示图象、文字、数字等多种内容，并且通过优化算法实现了上下左右移动，以及百叶窗等特殊效果。-To Silicon Laboratories, C8051F230 microcontroller to control the core, using 16-way dynamic scan mode to display the LED large screen display system design. Carried out using high-power transistor TIP127 line drive to improve the brightness. MCU by reading the external bus data can be realized with the host computer to work, you can also work independently from the host computer. High-speed microcontroller system can display images, text, numbers, and other content, and by optimizing the algorithm of the up and down and move around, as well as blinds and other special effects.

单片机控制的条码打印机程序,程序简单,功能齐全.-MCU-controlled bar code printer program, the program simple and functional.

共搜集了13个有关51单片机的一些基本程序，代码有汇编写成，内容包括计数器、温度检测等等。-collected a total of 13 of the 51 SCM some of the basic procedures, a compilation of code written, including counter, temperature measurement, and so on.
