Ticker

once()

Description:

Executes the callback function only once at a set time point (in seconds).

Syntax:

void once(float seconds, callback_t callback)

Example:

#include <M5Stack.h>
#include <Ticker.h>

Ticker ticker;  // Create a Ticker for implementing timing functionality

// This function will be executed periodically under the control of the Tinker object
void sayHi() {
    Serial.print("Hi,Ticker!");
}

void setup() {
    M5.begin();
    // Call the sayHi function once after 3 seconds
    ticker.once(3, sayHi);
}

void loop() {
    // M5Stack can perform other tasks periodically under the control of Tinker object
    Serial.println("Ticker");
    delay(1000);
}

once_ms()

Description:

Calls the callback function only once after a set time (in milliseconds).

Syntax:

void once_ms(uint32_t milliseconds, callback_t callback)

Example:

#include <M5Stack.h>
#include <Ticker.h>

Ticker ticker;  // Create a Ticker for implementing timing functionality

// This function will be executed periodically under the control of the Tinker object
void sayHi() {
    Serial.println("Hi,Ticker!");
}

void setup() {
    M5.begin();
    // Call the sayHi function once at 3000 milliseconds
    ticker.once_ms(3000, sayHi);
}

void loop() {
    // M5Stack can perform other tasks periodically under the control of Tinker object
    Serial.println("Ticker");
    delay(1000);
}

attach()

Description:

Executes the callback function periodically every set interval (in seconds).

Syntax:

void attach(float seconds, callback_t callback)

Example:

#include <M5Stack.h>
#include <Ticker.h>

Ticker ticker;  // Create a Ticker for implementing timing functionality
int count;  // Variable for counting

// This function will be executed periodically under the control of the Tinker object
void sayHi() {
    count++;
    Serial.print("Hi ");
    Serial.println(count);
}

void setup() {
    M5.begin();
    // Call the sayHi function every one second
    ticker.attach(1, sayHi);
}

void loop() {
    // M5Stack can perform other tasks periodically under the control of Tinker object
    Serial.println("Ticker");
    delay(3000);
}

attach_ms()

Description:

Executes the callback function periodically every set interval (in milliseconds).

Syntax:

void attach_ms(uint32_t milliseconds, callback_t callback)

Example:

#include <M5Stack.h>
#include <Ticker.h>

Ticker tickerSetHigh;
Ticker tickerSetLow;

void display(int number) {
  M5.Lcd.setCursor(0, 0);
  M5.Lcd.print(number);
}
void setup() {
  M5.begin();
  tickerSetLow.attach_ms(1000, display, 0); // Execute a callback function with parameters every 1 second
  tickerSetHigh.attach_ms(2000, display, 1);
}
void loop() {
}

attach() with Parameters

Description:

Executes the callback function with parameters periodically every set interval (in seconds).

Syntax:

void attach(float seconds, void (*callback)(TArg), TArg arg)

Example:

#include <M5Stack.h>
#include <Ticker.h>

Ticker tickerSetHigh; // Create a Ticker for implementing timing functionality
Ticker tickerSetLow;

void display(int number) {
    M5.Lcd.setCursor(0, 

0);
    M5.Lcd.print(number);
}
void setup() {
    M5.begin();
    tickerSetLow.attach(1, display, 0); // Execute a callback function with parameters every 1 second
    tickerSetHigh.attach(2, display, 1);
}
void loop() {}

attach_ms() with Parameters

Description:

Executes the callback function with parameters periodically every set interval (in milliseconds).

Syntax:

void attach_ms(uint32_t milliseconds, void (*callback)(TArg), TArg arg)

Example:

#include <M5Stack.h>
#include <Ticker.h>

Ticker tickerSetHigh;
Ticker tickerSetLow;

void display(int number) {
    M5.Lcd.setCursor(0, 0);
    M5.Lcd.print(number);
}
void setup() {
    M5.begin();
    tickerSetLow.attach_ms(1000, display, 0);
    tickerSetHigh.attach_ms(2000, display, 1);
}
void loop() {}
