![]() ![]() ![]() So there is an NTP request in setup() that executes once and for further use I would like to be able to call a function that gives back the current time in a time_t format without calling the NTP server at all. My current project is a device that will sleep for long times, then wake up for a short while and perform a task where it needs the time. Is there no way to read the synced time without calling out to the server? It looks like if I use the NTP object to get the current time in my sketch it always makes a call to the server and quite often this fails and I get a time of zero. If it is used for a timer interrupt, the delay can extend till the execution of. The NTP object should handle repeated sync to the server as needed, so as to limit network traffic. Learn to implement MicroPython timer interrupts in ESP8266 and ESP32. How do I read the current time as a time_t value inside the sketch at various places without actually calling the NTP server? I got advice and links to an NTP library to use.īut there is one thing I am not understanding how to do properly yet: ![]() In compare match, the interrupt is triggered when the timer. Timer1 can generate Compare Match, Overflow and Input Capture interruptions. Each of the three timers are able to generate different interrupts. Como el número de la interrupción varía en función de cada placa, es más cómodo indicar el pin con digitalPinToInterrupt (pin). This will cause the interrupt to occur as the value increases from 0-255 in the case of Timer2 and then goes back to 0 and repeats again. I have asked here before concerning usage of the NTP time servers to acquire accurate time via the network. Esta función tiene 3 parámetros: interrupt: El número de interrupción a usar (depende cada cada microcontrolador, ver tabla abajo) ISR: Nombre de la función a llamar. ![]()
