GitHub - khoih-prog/ESP32TimerInterrupt: This library enables you to use Interrupt from Hardware Timers on an ESP32-based board. 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. · GitHub

January 29, 2023 - You'll see software-based SimpleTimer ... as an example. The elapsed time then is very unaccurate · Before using any Timer, you have to make sure the Timer has not been used by any other purpose. Timer0, Timer1, Timer2 and Timer3 are supported for ESP32, ESP32_S2 and ESP32_S3. Timer0, Timer1 are supported for ESP32_C3. ... // Don't use PIN_D1 in core v2.0.0 and v2.0.1.
