(self. esp8266) submitted 2 years ago by Kwbmm. Generally in most languages when you're in interrupt handling functions you don't want to do anything fancy

Interrupts setuped with `attachInterrupt` are very slow

A timer lets you execute a branch at a regular interval. In this example the timer will fire ever 5 seconds and print some text to your browser window.

ESP32 Arduino: Timer interrupts – techtutorialsx

Interrupts The processor at the heart of any Arduino has two different kinds of interrupts: “external”, and “pin change”. There are only two external interrupt pins on the ATmega168 /328 (ie, in the Arduino Uno/Nano/Duemilanove), INT0 and INT1 , and they are mapped to Arduino pins 2 and 3.

Reverse engineering of the ESP8266 watchdog timer 21 February 2017 on esp8266. ESP8266 contains a hardware watchdog timer (WDT) module. As many parts of ESP8266, it is undocumented. In interrupt mode, WDT asserts interrupt number 8, it is possible to install custom handler with ets_isr_attach().

ESP32 MicroPython Tutorial: External interrupts

The esp8266 uses FreeRTOS with non-preemptible tasks and has extremely limited code space for interrupt handlers, as a result, it is not possible to handle certain peripherals at interrupt time and a task has to be scheduled instead, which would be OK if tasks were pre-emptible, but they are not.

Interrupts may be attached to any GPIO pin, except GPIO16. Standard Arduino interrupt types are supported: CHANGE, RISING, FALLING. Analog input. ESP8266 has a single ADC channel available to users. It may be used either to read voltage at ADC pin, or to read module supply voltage (VCC). To read external voltage applied to ADC pin, use
