Interruption problem with esp8266 (nodemcu; nodemcuv2, d1_mini . I have checked for them)

[alexgalstyan]

Hello Ivan, I have found problem with interruption after flashing board with PlatformIO compiling (With ARDUINO IDE have not a problem ): Also it was work normally about 3 or 5 month ago. I have project successfully compiled and used. At now I have problem with compiling this project

platformio settings:

`[env:nodemcu] platform = espressif8266 board = nodemcu framework = arduino ; COM-порт для загрузки upload_port = COM3 ; Скорость загрузки в baud upload_speed = 115200 ;921600 ; monitor_speed = 115200

//small sketch for checkin

include

const byte interruptPin = D5; //can use any PIN for test, the problem persists for all volatile byte interruptCounter = 0; int numberOfInterrupts = 0;

void handleInterrupt() { interruptCounter++; }

void setup() {

Serial.begin(115200); pinMode(interruptPin, INPUT_PULLUP); attachInterrupt(digitalPinToInterrupt(interruptPin), handleInterrupt, FALLING); //tried like attachInterrupt(interruptPin, handleInterrupt, FALLING); to

}

void loop() {

if(interruptCounter>0){

  interruptCounter--;
  numberOfInterrupts++;

  Serial.print("An interrupt has occurred. Total: ");
  Serial.println(numberOfInterrupts);

}

}`

result by serial getting: Processing nodemcu (framework: arduino; platform: espressif8266; board: nodemcu)

I have found some solve in GitHub forums

[1.] (https://github.com/sandeepmistry/arduino-LoRa/issues/254) 2. 3.

need to add ICACHE_RAM_ATTR for definitions ESP822 or ESP32(usind that boards) , or need use old core for example 2.0.4

[alexgalstyan]

Previous example with working condition: `#include

// #ifdef BOARD_ESP8266 // #define ISR_PREFIX ICACHE_RAM_ATTR // #elif BOARD_SOMEOTHER // #define ISR_PREFIX FAST_MEM_LOCATION // #else // #define ISR_PREFIX // #endif

ifdef ESP8266 || ESP32

#define ISR_PREFIX ICACHE_RAM_ATTR

else

#define ISR_PREFIX

endif

const byte interruptPin = D5; volatile byte interruptCounter = 0; int numberOfInterrupts = 0;

ISR_PREFIX void handleInterrupt() { interruptCounter++; }

void setup() {

Serial.begin(115200); pinMode(interruptPin, INPUT_PULLUP); attachInterrupt(digitalPinToInterrupt(interruptPin), handleInterrupt, FALLING);

}

void loop() {

if(interruptCounter>0){

  interruptCounter--;
  numberOfInterrupts++;

  Serial.print("An interrupt has occurred. Total: ");
  Serial.println(numberOfInterrupts);

}

}`

Thank very much alexgalstyan, very much helped me
