WIZnet
WizFi310 DNS TCP Helloworld library 2.0 version
Dependencies: WizFi310Interface_Legacy mbed
Prerequisite
This example shows that Wizwiki-W7500 and WizFi310 connect to a DNS server and get a its ip address. And then, It connects to '4.ifcfg.me' that returns an ip addess as TCP client.
To implement this function, you need a Platform board and Wi-Fi board. Below are what we used.
- WIZwiki-W7500 from WIZnet (Platform board)
- WizFi310 from WIZnet (Wi-Fi board)
Hardware Configuration
WIZwiki-W7500 Pin map
- D0 is for RXD, D1 is for TXD
- D6 is for CTS, D7 is for RTS
- D9 is for RESET
WizFi310 Pin map
- J1 is for RXD, J3 is for TXD
- SW6-1 is connected to D6 for RTS, SW6-2 is connected to D7 for CTS
- SW5-3 is connected to D9 for RESET
Connect to Wi-Fi
wizfi310.connect(SECURE, SSID, PASS);
Get information
const char *ip = wizfi310.getIPAddress(); const char *mac = wizfi310.getMACAddress();
Access to a 'mbed.org' website and get its ip addess
Endpoint addr;
addr.set_address("mbed.org", 80);
printf("mbed.org resolved to: %s\r\n", addr.get_address());
Access to a '4.ifcfg.me' as a TCP client and get its ip addess
TCPSocketConnection socket;
socket.connect("4.ifcfg.me", 23);
char buffer[64];
int count = socket.receive(buffer, sizeof(buffer));
printf("public IP address is: %.15s\r\n", &buffer[15]);
