My code is heavily based on this example of receiving the time from the internet: https://github.com/espressif/arduino-es ... leTime.ino I'd like to call a function whenever the second increments. I'm using to get the time and it's counting up in the background, so I'm wondering if there's something there that I can attach an interrupt to. Is this possible?

My alternative is to create a one second hardware timer interrupt and call the function there but I'd rather have my function exactly track the time.

Thanks in advance!

I'm wondering (out loud) if this library might serve you:

Simple Timer

It claims to have both a setInterval() and a setTimeout() pair of functions that take a callback function and a duration.

It might work - thanks for the response. I'm unable to tell if it's blocking or not. I want to run other code in the foreground of the while loop.

I was able to make something work using a hardware timer (https://github.com/dwaq/Super7Seg/blob/ ... no#L31-L43), but ideally I would like to base something entirely on the time.h library (https://github.com/dwaq/Super7Seg/blob/ ... pp#L70-L80). I think it might be a linux/ RTOS standard, so maybe I'm better off asking someone with expertise on that topic.
