the History of Computer

charles-babbage
long before we feel the sophistication of computer / laptop that is given in this modern era, we should learn to know the history of the manufacture of the first computer. The history of computers that need to be known in detail. The history of the development of computers began with the invention of a man named Charles Babbage. He is a scientist in the world who have made significant contributions to human life, especially the development of computers. 

The discovery of the phenomenal counter machine (Difference Engine No. 1) is one of the most famous inventions in the history of the development of computers and the first automatic calculator as a forerunner to the computer. The discovery was made ​​as the inventor Charles Babbage computer and dubbed as the father of computer. 

The history of computers that need to be known in detail. The history of the development of computers began with the invention of a man named Charles Babbage. He is a scientist in the world who have made significant contributions to human life, especially the development of computers. 

The discovery of the phenomenal counter machine (Difference Engine No. 1) is one of the most famous inventions in the history of the development of computers and the first automatic calculator as a forerunner to the computer. The discovery was made ​​as the inventor Charles Babbage computer and dubbed as the father of computer. 

Here is the history of computer and its development: 

1822: Charles Babbage proposed his idea of ​​a tool that can assist humans in performing calculations at a high level of complexity and complex. Buatanya engine unfinished musiumkan currently at the Museum of Science in London. 

1937: Dr. John V Atanasoff and Clifford Berry began making the first electronic digital computer design. They give the machine name ABC (Atanasoff-Berry Computer). The ability of the ABC machine was limited to counting added and reduction. 

1943: In World War 2, A British scientist named Alan Turing designed the electronic computer made ​​specifically for the British army. The purpose of making the computer so that it can be used to penetrate the German defenses code. 

1944: Howard Hathaway Aiken (USA) made ​​a named Mark I. It is a computer first digital count. The computer has an area of ​​7.45 feet x 50 feet, with a weight of 35 tons. Mark I already can be used to calculate probabilities. 

1945: Dr. John von Neumann wrote a concept of data storage. At that time still be ideas. 

1946: Dr. John W. Mauchly and J. Presper Eckert, jr. make the first large-scale computer, the computer name is the ENIAC (Electronic Numerical Integrator And Computer). World also assume these two people as the inventor of the digital computer. 

history of computers 

ENIAC computer weighs 30 tons, is composed of 18,000 light tube (transistor size), with a width of 30 feet x 50 feet, wearing power 160,000 watts. When first operated Firstly entire electricity network in the Philadelphia area suddenly died. 

ENIAC was a little more advanced than the Mark I, which only can count. ENIAC not only have the ability to count, add, less, times, to, but also can be programmed to perform a simple process.



1951: The US Bureau of Cencus installed the first commercial computer called UNIVAC I (Universal Automatic Computer). UNIVAC I was developed by Mauchly and Eckert for Remington-Rand Corporation.

1947: William Shockley, John Bardeen, and Walter Brattain The transistor is the inventor of the first in the world. Since ditemukanya transistors, computers become increasingly smaller sizes.

Similarly, the history of computer development from various sources. the long journey that now we can feel the computer is already very advanced.

Intro - AVR CodeVision

Intro -  AVR CodeVision
now we will be a little review about the programming language for digital electronics. who want to learn mrogram robot, LCD, etc. it is advisable to try this software ..
yuuk .. together we learn ..

CodeVisionAVR is a free software that serves as a text editor in writing as well as a command line compiler that can transform the source file into a hex file. CodeVisionAVR software demo version can be downloaded from http://www.hpinfotech.ro/cvavr_download.html.
CodeVisionAVR provide various facilities that enable the user. One is CodeWizardAVR that provides the ease of configuration pin functions and features that you want to use. Users can create and run programs written, then test it step by step so that the user can observe changes to the data in each register and the I / O ports.
Additionally CodeVisionAVR also provides a toolbar that allows users to perform a variety of desired interactions, and also has a working arena quite freely.
INSTALLATION
So that the user can use the software CodeVisionAVR then the user must install it first. CodeVisionAVR The software installation process is quite easy.
Double-click the master program CodeVisionAVR.
Follow the steps that are required and make changes as needed.
Once completed, the program can be directly executed.
MAKE A NEW PROGRAM
Creating a new program using CodeVisionAVR not difficult. The steps that must be done is as follows:

Run the program CodeVisionAVR. With a double click on the Icon CodeVisionAVR as in figure 1.1.
Icon CVAVR
Figure 1.1 Icon CodeVisionAVR
At the time of the program run CodeVision AVR then a blank screen appears as shown in figure 1.2.
Tampilan awal
Figure 1.2 Display Code Vision AVR
 Click the File menu and select New, then the selection window appears as in Figure 1.3.
Create new File
Figure 1.3 Window Option File Type
To create a new program choose Project and then click OK, then comes the question that asks if we want to use CodeWizard AVR as in figure 1.4 below, then select Yes.

Confirm
Figure 1.4 Window Confirm CodeWizardAVR

CodeWizardAVR window appears as Figure 1.5. On the Chip tab, do the configuration as shown in figure 1.5.
Code Wizard
Figure 1.5 CodeWizardAVR on Chip tab

Next select the Ports tab, and then do the settings as shown in figure 1.6.

Code Wizard PA
Figure 1.6 CodeWizardAVR on Ports tab

Then select the File menu and select Generate, Save and Exit. Then we asked to store three types of files in sequence. Recommended third save the file in the same folder.
Once completed, the program will look like the image CodeVisionAVR 1.7, which shows that there has been a program that has been configured and ready to use or insert additional program.

Figure 1.7 CodeVision Programme configured AVR AVR Figure 1.7 CodeVision program is configured


Then prepare the main program as shown in Figure 1.8 below.
code
Figure 1.8 Inserting the main program

Once done we can compile the program by going to the Project menu and select Build All or Ctrl + F9
If the program is correct or not there is an error, it will show the information window as shown below 1.9

information
Figure 1.9 Window Information

Then click OK, and the program ready for download to the circuit. 
Langlah-step process above is to generate a file with the machine language hex file with the extension 
(*.hex). This file is required to be filled out (download) to the microcontroller IC, because the microcontroller only understands machine language. These stages will continue to be made each create a new program.
