Step 1: Hardware required by the Ardiuno web server
Perfect Arduino Development Board
Arduino Ethernet profile
Circuit
Ethernet shield allows you to combine WIZNET Ethernet controllers with Arduino via the SPI bus. Higher version of Ethernet protective cover also prepares an SD card. Advanced four pins are used to control the slave selection rod on the SD card.
Write
If it is embedded in the SD card, do not use it to hang, the reason is to use the rocker 4 as SS (dynamic low), and when the rocker 4 is not used, it is naturally arranged to input. Divided into two parts:
Delete SD card;
In setup () contains the following code rows
PINMODE (4, OUTPUT);
DigitalWrite (4, high);
Step 2: Step 2: Web Server
A basic web server for presentation
Simple information pin estimation.
Use Arduino Wiznet Ethernet.
I am also seeking assistance in the expert group, not because I am too lazy, I don't want to replace the code, but because I realize that I don't have the most effective code, because I have been customizing in c, which is in just a few years in just a few years. Part is used in the Arduino field.
Any tutorial is provided when uploading the code. It creates a web server in your LAN, you only need to use IP to access the web server via the program. After that, it will show a similar website page below. When you press the Catch "Open LED" button, your URL will change to Arduino, which will read the data and open the LED.
Make web pages
Since the website page is to be placed on the SD card, you should first use the content manager to make it, then copy it to the SD card.
Web editor
One content tool can be used, such as Geany - can be downloaded from Windows, and can be found in most Ubuntu-based Linux release. Geany has a prominent language structure, so it will turn off the HTML tag, which reduces the requirements of the website page. You can imagine using some other content tools, even including Windows Notes.
Web page
A setable web page is created in the text processor. When the backup content record, please provide name: Index.htm
Copy page
You will need to open the Micro SD card, your machine or memory card for each user, suitable for reading and forming a Micro SD card.
The micro SD card is embedded into the opening on the machine or inserts the card of each user connected to the machine, and then copies the index.htm document into the micro SD card.
The SD card is currently connected to the miniature SD card opening on the Ethernet shield.
Step 3: Step 3: SD Card Web Server
hardware
You should now put a micro SD card with a copy web page into the card opening on the Arduino Ethernet shield. Ethernet screen should be connected to good Arduino and connect to an Ethernet link associated with your system. Arduino / Ethernet shield should be controlled via a USB link.
Fault look
It is expected that the main thing that may occur is to introduce the SD card and implement index.htm details on the card. If the document is not on the card or does not have a clear name index.htm, the server will not have the right to display the web page.
Open the Arduino serial screen window to view the SD card analysis data.
Additional code
This representation is now in initializing the NIC works in Setup () and sends the symptom data to the serial port you can see in the Arduino serial screen window.
In contrast from the ETH_WEBSRV_PAGE sketch, this new contour now opens index.htm details from the SD card, then sending substantive content to the network user (network program). The team accepts 40G Ethernet will provide a fee between the local area network and the connection site.
After debugging, this code is collected from approximately 29k, and no debugging is collected by 27.5k. This will not waste a lot of programs or SRAM memory on the UNO.
Step 4: Step 4: Installation instructions
Using Arduino, its more use is overview to use in MEGA or other models with different memory. 0016 or earlier, put the webserver.h document in the Fittings / Libraries / Web Duino subdirectory of the Arduino tree.
For Arduino 0017 or higher, add the WebDuino organization to the "library" envelope of the sketch directory.
If you receive an error message when you construct a case where you find the WebServer.h, you are placing the WebDuino Manager. If the header is specifically used for the server, the server will not work in the library organizer.
