Calling different funcion from same interrupt pin

Mbed OS
5

I probably did not understand the task, according to your second topic, but I will place here a code anyway.

#include "mbed.h"

#define VARIANTSMAX 2
#define LOWTIME 200
#define HIGHTIME 500ms

DigitalOut led1(LED1);
InterruptIn button(BUTTON1);
Timeout tOut;

volatile bool buttonFlag = false;

void PressHandler(){
    if(!buttonFlag){
        buttonFlag = true;
        button.disable_irq();
    } 
}

volatile bool timeOutFlag = false;

void TimeOutHandler(){
    if(!timeOutFlag ){
        timeOutFlag  = true;
    } 
}

long Millis(void) {
    using namespace std::chrono;
    auto now_ms = time_point_cast<milliseconds>(Kernel::Clock::now()); // Convert time_point to one in microsecond accuracy
    return now_ms.time_since_epoch().count();
}

int main()
{
    printf("Running on Mbed OS %d.%d.%d.\n", MBED_MAJOR_VERSION, MBED_MINOR_VERSION, MBED_PATCH_VERSION);
    printf("Multiple button press test\n");
    button.fall(callback(&PressHandler));
    int counter = 0;
    long last_ms = Millis();
    
    while (true)
    {
        if(buttonFlag){
            long timeTemp = Millis(); 
            if((timeTemp - last_ms) > LOWTIME){
                tOut.attach(callback(&TimeOutHandler),HIGHTIME);
                if(++counter >= VARIANTSMAX){
                    tOut.detach();
                    timeOutFlag = true;
                }
            }
            last_ms = timeTemp;
            buttonFlag= false;
            button.enable_irq();
        }
        if(timeOutFlag){
            button.disable_irq();
            switch (counter) {
                case 1:{
                    printf("Case %d\n", counter);
                    break;
                }
                case 2:{
                    printf("Case %d\n", counter);
                    break;
                }
            }
            counter = 0;
            timeOutFlag = false;
            button.enable_irq();
        }
        //led1 = !led1;
        //thread_sleep_for(WAIT_TIME_MS);
    }
}
