{| style="width: 800px;" |- | ==Purpose== The course will show you how to turn your Microduino to a server, enabling you to browse it at home. ==Equipment== *'''[[Microduino-Core]]''' *'''[[Microduino-USBTTL]]''' *'''[[Microduino-W5500]]''' *'''[[Microduino-RJ45]]''' *Other hardware equipment **USB cable One == World Wide Web== Webpage is consisted of HTML markup language, which adopts mark to describe web content. The main advantage of using HTTP protocol to communicate with Microduino online is: *You can use comment browsers such as ID and Firefox without the need to develop special client. *You can use Microduino character string function to manage HTTP protocol. *You can also adopt Microduino to create page or even dynamic one. ==Schematic== *Microduino-ENC28J60 *Microduino-RJ45 *Microduino-Core *Microduino-USBTTL Stack them and plug in cable. As follows: [[File:MicroduinoW5500Show.png|600px|center|thumb]] ==Program== [[https://github.com/Microduino/Microduino_Tutorials/tree/master/Microduino_Advanced_Tutorial/W5500Code/MicroduinoW5500Five MicroduinoW5500Five]] ==Debugging== Step 1: First, make sure you have _02_Microduino_Ethernet_WIZ library in your IDE and put it into libraries folder of your IDE. Step 2: If there still exists the previous Ethernet library in your libraries folder, it needs to be deleted since the previous Ethernet is compiled according to W5100. Then, you need to change _02_Microduino_Ethernet_WIZ file so that the library function could be corresponding with Microduino-W5500: First find w5100.h of utility in _02_Microduino_Ethernet_WIZ library. Change #define wiz_cs_pin 8 //CS_PIN of the code to #define wiz_cs_pin 10 //CS_PIN. Step 3: Interpret the code: The program will first monitor if service is visited. while (client.connected()) { If yes, it will send analog values of 0~5 to client analog port: // send a standard http response header client.println("HTTP/1.1 200 OK"); client.println("Content-Type: text/html"); client.println("Connection: close"); // the connection will be closed after completion of the response client.println("Refresh: 5"); // refresh the page automatically every 5 sec client.println(); client.println("<!DOCTYPE HTML>"); client.println("<html>"); // output the value of each analog input pin for (int analogChannel = 0; analogChannel < 6; analogChannel++) { int sensorReading = analogRead(analogChannel); client.print("analog input "); client.print(analogChannel); client.print(" is "); client.print(sensorReading); client.println("<br />"); } client.println("</html>"); break; Step 4: Download code and compile. Step 5: Check your IP address via serial port and enter corresponding IP address of Microduino in the browser. ==Result== The result should be: [[File:MicroduinoW5500ShowAnalog0-5.png|600px|center|thumb]] Serial port cut figure as follows: [[File:MicroduinoW5500SerialCutImage.png|600px|center|thumb]] ==Video== |}
