Microduino W5500 Network (3)

Purpose The course will show you how to send data to one website and receive returned data of the website. Equipment Microduino-Core Microduino-USBTTL Microduino-W5500 Microduino-RJ45 Other hardware equipment USB cable One Schematic Microduino-W5500 Microduino-RJ45 Microduino-Core Microduino-USBTTL Stack them and then plug in cable. As follows: Program [MicroduinoW5500Three] 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: Here is a simple php webpage. http://www.lucadentella.it/demo/aphorisms.php Each time you open the link, it will return you a maxim. The code we complied can get these maxims and output to serial port. // if you get a connection, report back via serial: if (client.connect(server, 80)) { Serial.println("connected"); // Make a HTTP request: client.println("GET /demo/aphorisms.php HTTP/1.1"); client.println("Host: www.lucadentella.it"); client.println("Connection: close"); client.println(); } else { // if you didn't get a connection to the server: Serial.println("connection failed"); } First, visit this page in the code. // if there are incoming bytes available // from the server, read them and print them: if (client.available()) { char c = client.read(); Serial.print(c); } Output the returned info. to serial port and when failed to visit, you’ll see notice in the serial port Step 3: Download code and pass compile. Step 4: Watch the serial port. Result If everything goes well, you’ll see the information below: It will show a maxim randomly and then close. Video
