Hardware Timer Interrupt

Hardware and Blynk Libraries

Dear @mikekgr,

Have a look at example, ISR_Timer_Complex, written for specially for Blynkers, where you can use the same syntax as BlynkTimer and the library is specially written to replace software timers. You can use it if absolutely necessary for mission-critical tasks. In this example, an LED is toggled every 5000ms by an ISR-based timer.

[https://github.com/khoih-prog/ESP8266TimerInterrupt/tree/master/examples/ISR_Timer_Complex]

You can see the terminal output like this:

Starting
ESP8266TimerInterrupt: _fre = 312500.00, _count = 15625
Starting  ITimer OK, millis() = 64
doingSomething2s: Delta ms = 2000   // ISR_Timer, 2000ms interval, still working even if blocked by WiFi/Blynk connecting tasks
doingSomething2s: Delta ms = 2000
doingSomething5s: Delta ms = 5000
Delta ms = 5000                     //ISR_Timer, 5000ms interval, blynking an LED
doingSomething2s: Delta ms = 2000
