khoih-prog / TimerInterrupt

This library enables you to use Interrupt from Hardware Timers on an Arduino, such as Nano, UNO, Mega, etc. It now supports 16 ISR-based timers, while consuming only 1 hardware Timer. Timers' interval is very long (ulong millisecs). The most important feature is they're ISR-based timers. Therefore, their executions are not blocked by bad-behaving functions or tasks. This important feature is absolutely necessary for mission-critical tasks.

Hi @csaba911

Thanks for using the library, but you're either using the wrong library or post the issue in the wrong library.

This TimerInterrupt Library is designed only for certain supported Arduino boards in this list of Supported Arduino Boards.

For ESP32, you have to use this ISR_RPM_Measure example after installing this ESP32TimerInterrupt Library

Hi @csaba911

If you're using the correct ESP32TimerInterrupt Library, then please fix the typo in the ISR_RPM_Measure example as follows:

From

// Interval in microsecs
  if (ITimer1.attachInterruptInterval(TIMER1_INTERVAL_MS, TimerHandler1))
    Serial.println("Starting  ITimer1 OK, millis() = " + String(millis()));
  else
    Serial.println("Can't set ITimer1. Select another freq., duration or timer");

To

// Interval in microsecs, must multiply 1000
  if (ITimer1.attachInterruptInterval(TIMER1_INTERVAL_MS * 1000, TimerHandler1))
    Serial.println("Starting  ITimer1 OK, millis() = " + String(millis()));
  else
    Serial.println("Can't set ITimer1. Select another freq., duration or timer");

Hi @csaba911

Just fix the typo in the ISR_RPM_Measure example of ESP32TimerInterrupt Library.

Thanks,
