DDNS use No-IP
Dependents: TCPEchoClient-WIZwiki-W7500
Prerequisite
This is DDNS_NoIP Library. DDNS(Dynamic DNS) host name is linked up to the uesr's dynamic IP address. Whenever the IP changes a dynamic DNS client will send an update to No-IP with the current IP address and then No-IP propagates the DNS change to the internet within seconds.
DDNS Configuration
NoIP Site
Hardware Configuration
WIZwiki-W7500 Pin map
Software
DDNS
/* Set ID Pass and Hostname */ void userSetNoIP(char* idpass, char* hostname); /* Upload DDNS IP Address */ void updateNoIP(void); /* Check DDNS IP Address */ void checkIp(void);
