Is It possible to get time remaining until the end?

Hi,

I appreciate your work and I would know if is possible to show the time remaining until the end.

For example, I have a countdown with a specific time using the function in(), but I want to show the time remaining in a display.

I tried use the function every() but in the looping the time is desynchronized because I have some delays.

An exemple of code to illustrate that.

`#include

auto t = timer_create_default();

int timerToShow = 60000; int timerToShowArduino = 60000;

long previousMillis = 0; const int maxTime = 1000;

bool counting = false;

bool updateTimer(void *) { timerToShow -= 1000; return true; }

void updateTimerByArduino() { timerToShowArduino -= 1000; }

bool finishTimer(void *) { Serial.println("finish"); counting = false; t.cancel(); return true; }

void setup() { Serial.begin(9600); Serial.println("start"); counting = true; t.in(timerToShow, finishTimer); t.every(1000, updateTimer); }

void loop() { if(millis() - previousMillis >= maxTime) { previousMillis = millis();

    t.tick();

    updateTimerByArduino();

    if(counting) {
      Serial.println(String(t.ticks()) + "|" + String(timerToShow) + "|" + String(timerToShowArduino));
    }

    delay(1500);

} }`

In this case when the call finishTimer() in the correct time, the counters are on 20000 yet.

Can you help me?

I've improved the code using Millis() but your lib have doesn't a function to do that?

void updateTimerByArduino() { timerToShowArduino += (timePast - millis()); timePast = millis(); }
