利用HD66421实现灰度字符显示，keilC51编译环境

具有固定的“红灯―绿灯”转换间隔，并自动切换。它们一般由“通行与禁止时间控制显示、红黄绿三色信号灯和方向指示灯”三部分组成。在交通灯的通行与禁止时间控制显示中，通常要么东西、南北两方向各50秒；要么根据交通规律，东西方向60秒，南北方向40秒，时间控制都是固定的。交通灯的时间控制显示，以固定时间值预先“固化”在单片机中，每次只是以一定周期交替变化。-having fixed the "red light-green light" switch partitions, and automatic switching. They are generally from "prohibiting access and time control, red-yellow-green lights and direction indicator" is composed of three parts. Traffic lights in the passage of time and prohibit control indicates that things are usually either the north-south direction of the two 50 seconds; either on the basis of traffic laws, an east-west direction 60 seconds, 40 seconds north-south direction, the time control are fixed. Traffic lights to the time control, a pre-fixed time value "cured" in SCM, each is a certain cycle alternation.

在IAR Embedded Workbench IDE平台使用ATmega1280的USART1口的编译连接通过的485通信的master机和slave2以及slave3的程序-IAR Embedded Workbench IDE in the platform of the ATmega1280 compiler USART1 I connect the 485 through the master communication and slave3 procedures, as well as slave2

利用89S52为核心实现的IDE-USB转接器 现在已经实现了主要功能：可以读取文件和复制文件。不支持格式化硬盘功能。 不过速度比较慢，我从本地硬盘复制文件到移动硬盘里去，速度只有50KBytes/S， 因为单片机速度不快，内存又少，USB1.1的速度也不快。另外，代码写得不够好 压缩包内有线路图-89S52 realize use as the core of the IDE-USB adapter now realize the main function: You can read the files and copy files. Reformat your hard disk does not support the function. More slowly, however, I copy files from the local hard disk to a mobile hard drive into a speed only 50KBytes/S, because of slow single-chip, memory less, USB1.1 speed is not fast. In addition, the code written is not good enough compression packages have circuit diagram

这是isd4004的中文资料，里面讲述了其与单片机控制原理和机制-This is the Chinese isd4004 information, which describes its relationship with single-chip control theory and mechanisms

这是用PIC芯片处理USB的源代码,包括初始化USB，中断设置等，是汇编语言入门USB操作的很好参考程序！-This is the PIC chip USB source code, including the USB initialization, interrupt settings, assembly language entry USB good reference operating procedure!

51单片机写得温度控制，经调通的程序 可以给初学者作为参考-51 Single-chip temperature control written by the tune
