C8051F120 UART complete program, its compilation, and test

请将下载的2个插件内容拷贝到uVision 的安装目录下的 KeilC51BIN 中 2. 修改 Tool.ini, 此文件位于 uVision 的安装目录 keil 下. 请将下面的内容 添加到 [C51] 部分的后面. AGSI1=ledkey.dll ("ledkey") AGSI2=simboard.dll ("simboard") 3. 重启uVsion. 进入Debug 模式, 打开菜单Peripheral, 发现增加了2项 分别是键盘LED仿真板，51实验仿真板。-Please download the contents of two plug-ins are copied to the installation directory uVision under KeilC51BIN 2. Modify Tool.ini, this file is located in the installation directory uVision under keil. Please Add the following line to [C51] part of the back. AGSI1 = ledkey.dll (ledkey) AGSI2 = simboard.dll (simboard) 3. Reset uVsion. entered the Debug mode, open the menu Peripheral, found an increase of 2 are keyboard LED emulation board, emulation board 51 experiments.

粮情测控系统的设计 （基于凌阳单片机）硬件软件设计-Grain monitoring and control system design (based on Sunplus Single-chip) hardware and software design

基于Ramtron公司的VRS51L3074高性能8位单片机的MP3(VS1003)驱动程序,程序在Keil环境编译,程序内自带一段15K左右的MP3文件,可以直接播放测试.-Based on Ramtron" s VRS51L3074 high-performance 8-bit microcontroller MP3 (VS1003) drivers, programs, the environment in the Keil compiler, the program comes with a 15K or so inside the MP3 files can play test.

51的GPIO模拟iic的驱动程序，用宏来定义硬件管脚，容易移植，keil平台-51 GPIO IIC driver simulation, using macros to define the hardware pin, easy to transplant, keil platform

由于输出的是方波，比较难听:-) 只能说是非常难听:-)为什么呢？只因为输出的是方波,包含了大量的奇次谐波。 你可以用双龙的"虚拟仪器"分别产生正弦波、三角波和方波听一下，正弦波感 觉就比较纯正，而方波则要多难听有多难听！-As the output is a square wave, more bluntly :-) can only say that it is very nasty :-) Why? Simply because the output is square wave, including a large number of odd harmonics. You can use Shuanglong

usb程序 硬件用的是isp1518，传输方式dma-usb hardware procedure is used isp1518, transmission dma

一款车载DVD音频处理IC驱动程式，很有参考价值。-Deal with a car DVD audio driver IC, it is reference value.

本人所做项目中用51系列单片机(STC89C58RD)对OCMJ8*15B液晶屏进行数据写操作时所写的配套源代码,可以直接在keil7.0以上的版本中嵌入开发！应该说本程序有很高的实用价值（本人开发的产品已应用于实际工业控制中）-I conducted a series of 51 projects using SCM (STC89C58RD)* 15 OCMJ8 B LCD screen for data write operation written by supporting source code, keil7.0 directly on the above versions embedded development! It should be said that this program has high practical value (I development of the product has been used in practical industrial control)

采用C51编写的基于C8051F020单片机的电机测速使用程序。-using C51 prepared by the C8051F020 Motor gun procedures.

基于8051F020,目的：用PCF8574器件实现并口输入，输出操作-Based on 8051F020, Objective: To realize parallel PCF8574 device input and output operation
