arduino中no matching function for call to 'Ticker::Ticker(void (&)(), int)'

It seems like you are trying to create a Ticker object without specifying a function to call. The Ticker library in Arduino requires you to provide a function to call at a specific interval.

Here's an example of how to create a Ticker object that calls a function every 1000 milliseconds:

#include <Ticker.h>

void myFunction() {
  // do something
}

Ticker myTicker(myFunction, 1000); // create a Ticker object that calls myFunction every 1000 milliseconds

Make sure you have included the Ticker library at the beginning of your sketch:

#include <Ticker.h>

Also, make sure that your function matches the Ticker library's function signature:

void myFunction() {
  // do something
}

It should not have any parameters and return void.
