in the favicon.h file
- Code: Select all
const prog_char favicon[] PROGMEM = { some hex};
I'm seeing the serial data that the icon is being called for on the terminal, this a copy and paste from the example.
- Code: Select all
// Check if request is for the favicon
if (strcmp(URL, "/favicon.ico") == 0) {
// Write the bytes of the favicon that are stored in flash as defined
// by favicon.h. Always use the special _P functions to write data that's
// stored in flash
WiServer.print_P(favicon);
Serial.println("The Image has been requested"); //This is being called when the page loads
return true;
}
- Code: Select all
WiServer.print("<img src=\"favicon.ico\">");
The full program, note the code is borrowed from a post I read here and most of which is not my own, though I do understand how it works.
- Code: Select all

Any help would awesome.
