Extreme PowerSave Mode ESP8266 powered ON after External Interrupt
Ticker performs same function as timer. In this tutorial we will see both Timer and Ticker examples ESP8266 Ticker Example Ticker is library for calling functions repeatedly with a certain period. Ticker is os_timer Each Ticker calls one function. You can have as many Tickers as you like, memory being the only limitation.

ESP8266 External Interrupt Example Interrupting
Code Explanation: ESP8266 GPIO Interrupt The ESP8266 allows you to set up GPIO pin interrupts that are triggered when the logic level of a pin changes. On an ESP8266 board, all GPIO pins, with the exception of GPIO16, can be configured to function as inputs for interrupt requests.
Using Interrupts on the Adafruit Feather Huzzah with ESP8266 Duct
Interrupts can be used on the ESP8266, but they must be used with care and have several limitations: Interrupt callback functions must be in IRAM, because the flash may be in the middle of other operations when they occur. Do this by adding the IRAM_ATTR attribute on the function definition.

An external interrupt or a 'hardware interrupt' is caused by the external hardware module. For example, there is a Touch Interrupt which happens when touch is detected and a GPIO interrupt when a key is pressed down. In this tutorial, the interrupt will be triggered when the motion will be detected.

1. Define an interrupt handling function. The interrupt handling function should be as simple as possible, so the processor gets back to the execution of the main program quickly. The best approach is to signal the main code that the interrupt has happened by using a global variable, for example.
digital logic Putting an ESP8266 to sleep via either of two signals
GPIO interrupt pin. The first argument is a GPIO interrupt. You should use digitalPinToInterrupt(GPIO) to set the actual GPIO as an interrupt pin. For example, if you want to use GPIO 14 as an interrupt, use: digitalPinToInterrupt(14) The ESP8266 supports interrupts in any GPIO, except GPIO16. ISR
ESP8266 Interrupts and Timers Arduino IDE PIR Motion Sensor Example
The Interrupt Service Routine (ISR) is a function that is invoked every time an interrupt occurs on the GPIO pin. Its syntax looks like below. void ICACHE_RAM_ATTR ISR() { Statements; } ISRs in ESP8266 are special kinds of functions that have some unique rules that most other functions do not have.
MicroPython Interrupts with ESP32 and ESP8266 PIR Sensor Example
The code We will start our code by declaring some global variables. The first one will be the pin where the interrupt will be triggered. Interrupts may be attached in all the GPIOs of the ESP8266, except for the GPIO16 [3]. For this example, we will use GPIO13.
ESP8266 pinout reference and how to use GPIO pins
NodeMCU has Interrupts functions on its GPIO pins. It provides a way to get noticed by external events.
Programming ESP8266 With Arduino IDE The Easy Wayelab Rik
This library enables you to use Interrupt from Hardware Timers on an ESP8266-based board. It now supports 16 ISR-based timers, while consuming only 1 hardware Timer. Timers' interval is very long (ulong millisecs). The most important feature is they're ISR-based timers. Therefore, their executions are not blocked by bad-behaving functions or tasks.
MicroPython Interrupts with ESP32 and ESP8266 PIR Sensor Example
The first argument is a GPIO interrupt. You should use digitalPinToInterrupt (GPIO) to set the actual GPIO as an interrupt pin. For example, if you want to use GPIO 14 as an interrupt, use: digitalPinToInterrupt(14) The ESP8266 supports interrupts in any GPIO, except GPIO16. ISR
Tips ESP8266 UART Rx Interrupt Short version YouTube
To set up interrupts on the ESP8266, the following steps are typically involved: : The first step is to attach an interrupt handler function to a specific interrupt pin. This informs the microcontroller which function to call when the specified event occurs. : Next, you need to define the interrupt handler function.

To work with interrupts on ESP8266, follow these steps: Set the GPIO pin as an interrupt pin with the desired mode (e.g., change, falling, rising). Implement an ISR that performs the necessary actions when the interrupt event occurs. Attach the ISR to the interrupt pin. Enable interrupts globally.
