串口扩展LED时钟子程序，不含时间设定，可直接嵌入串口LED显示系统中...

本程序是4×4键盘的mega16采样子程序，本程序参考了它人的设计，现在已经在我的项目中使用，其最大的特点就是硬件简单，调试方便，大家不用动脑筋就搞定它了。-This procedure is a 4 × 4 keyboard mega16 sampling subroutine, the procedure with reference to the design of its people, is now in my project to use, its greatest feature is the hardware is simple, easy debugging, you do not use their brains to get it .

电动车上面的控制器原理图，NEC主控芯片，现在最流行的方案，提供给大家-Electric vehicle controller schematic diagram above, NEC host chip, is now the most popular programs available to everyone

单片机矩阵键盘扫描程序，已经做成了头文件，非常好用-MCU matrix keyboard scanning process, has made a header file, very easy to use

本人以前做的一个DVD+TV 项目，51用做控制，含 NEC红外遥控接收和转发，VFD1632驱动，OSD 芯片M35055，NTSC高频头控制以及I2C 24C02的读写，因为以前所写，有些地方看起来有点乱，但功能模块OK，整个程序也是可以运行的，希望能给初用者有点参考-I used to do a TV DVD, 51 used as a control, with NEC infrared remote control and forwarding, VFD1632 drive, OSD M35055 chip, NTSC tuner control and I2C 24C02 read and write, because it was written in some places appear to be a little messy, but functional modules OK, the entire procedure can be run in hopes of giving users a bit early reference

基于51单片机，实现RS232和RS485两机通信，包含详细说明！

仿真步骤如下： 1、把3个帖子的内容分别保存为51t9py.c,51t9py_indexa.h,5py_mb.h，放在同一目录下，将51t9py.c加入工程编译 2、由于Keil的模拟串口是单字节显示，汉字显示为乱码，所以要加挂RICHWIN或RichView这种会重新刷新显示的中文平台，或手工刷新屏幕，所以请先到 http://www.pchome.net/dl/chinese.htm 下载RichView，安装运行 3、在Keil环境下可以直接按“Ctrl＋F5”键仿真，按“F5”全速运行，切换到在串口依次输入: // 64*.6 426***.5 98*.7 936.3 586.1 4826*.1 9464*.7 64*.6试试:-) 4、按键对应(根据我自己的手机设置的,全部在PC的小键盘操作)： -simulation steps are as follows : 1 and 3 respectively, the content of messages posted on the preservation of 51t9py.c, 51t9py_indexa.h, 5py_mb.h, on the same directory, will join the project 51t9py.c compiler 2, Keil is the simulation of single-byte Serial show , the Chinese showed gibberish, so need to add or RichView RICHWIN this show will re-set the Chinese platform, or manual refresh screen, so please download RichView http://www.pchome.net/dl/chinese.htm to install three operations in Central Keil Habitat can be directly "Ctrl+ F5" key simulation, according to the "F5" running full-speed, switched to the ser
