Description: This sample displays a basic integer calculator powered
by the 8051 microcontroller. Although Keil C51 has a
full floating point math library the evaluation version
is restricted to 2k of object code, so we have constrained
this sample to integer maths in order to fit within this limit.
The program for this design was written in C using the
Keil uVision 2 IDE for which Proteus VSM provides
a Debug Monitor driver.
Instructions for configuring Proteus to run in conjunction
with the Keil environment can be found by editing the
8051 microcontroller on the schematic (point at it and
press CTRL-E) and then clicking on the help button
on the Edit Component dialogue form. Platform: |

Description: The DHRY program performs the dhrystone benchmarks on the 8051.
Dhrystone is a general-performance benchmark test originally
developed by Reinhold Weicker in 1984. This benchmark is
used to measure and compare the performance of different
computers or, in this case, the efficiency of the code
generated for the same computer by different compilers.
The test reports general performance in dhrystones per second.
Like most benchmark programs, dhrystone consists of standard
code and concentrates on string handling. It uses no
floating-point operations. It is heavily influenced by
hardware and software design, compiler and linker options,
code optimizing, cache memory, wait states, and integer
data types.
The DHRY program is available in different targets:

Description: CS8955控制TV软件。用MCU做模拟电视的控制。-CS8955+TV+TNJ7355(tuner).The CS8955 micro-controller is an 8051 CPU core
embedded device targeted for LCD Monitor, LCD TV,
Home Appliance, or Consumer Products application.
The CS8955 is pin-out compatible with MCS-51
family .MCU. It includes an 8051 CPU core, a 64K-byte
internal program Flash-ROM, a 512-byte SRAM, 6
channels of PWM DAC, and 4 channels of 6-bit ADC
(Analog to Digital Converter). It also includes a Boot-
Code-Free ISP (In System Programming), which
allows users to update the programming codes easily.
In addition, there are two IIC Slave B ports supporting
VESA DDC 2B/2Bi/2B+/CI standards for both D-sub
and DVI interfaces in LCD Monitor/TV application. An
external 64K bytes data flash memory can be
accessed by properly setting of Port 0, Port 2 and
Port 3.6/3.7.

Description: LCD在电子产品设计中使用率相当高，普通的七节显示器只能用来显示数字，若要显示英文文字时，则一定会选择使用LCD（液晶显示器），常见的使用场合有量测仪器及高级电子产品，毕竟LCD价格不是很便宜。我们在电子材料行买到的LCD，其背面含有控制电路，其上面有专门的IC来完成LCD的动作控制，在自行设计的接口中，只要送入适当的命令码和欲显示的数据，LCD便会将其字符显示出来，在程控上非常方便-LCD in electronic product design, very high utilization rate, the average seven monitors can only be used to display numbers, to display the English text, then will choose to use LCD (liquid crystal display), commonly used measurement instruments and occasions advanced electronic products, after all, LCD prices are not very cheap. Our line of electronic materials commercially available LCD, its back contains a control circuit, which have specialized IC above the LCD to complete the action control, self-designed interface, as long as the appropriate commands into the code and want to display the data, LCD characters will be displayed in the very convenient program-controlled Platform: |

Description: 基于AT89S52的GSM安防系统
本人最近弄了个基于AT89S52的GSM安防系统，想到当初由一个新手开始做这个的时候在找案例参考基本都看不懂。所以我做好这个项目后，就把它无私贡献给大家。希望对有兴趣的朋友有所帮助。这是一整套的成品，里面有说明文档，99SE的原理图和PCB，还有全套代码。在这里需要说明一点的是，由于本人孤军做此项目，所以很多地方都不是很完善。
该程序已经实现发生警报，然后通过GSM发送短信到目标号码，然后由目标再回发相应的控制短信去控制。
更多请查看附件里面的说明文档-AT89S52 based on the GSM security system
I recently broke a AT89S52 of GSM based security systems, originally thought of starting from a novice to do this when looking for the basic reference case are read. So I do this project, put it selflessly to the party. Want to help friends who are interested. This is a set of finished product, which has documentation, 99SE schematic and PCB, have a complete code. Need to point out here is that, because I alone in doing this project, many places are not quite perfect.
The program has been achieved alarm occurred, and then send text messages to the destination GSM number, and then issued by the goal of returning to the corresponding control messages to control.
