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 library enables you to use Interrupt from Hardware Timers on supported Arduino boards such as AVR, ESP8266, ESP32, SAMD, SAM DUE, nRF52, Teensy, etc. These Hardware Timers, using Interrupt, still work even if other functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other softw…

This library enables you to use 1 Hardware Timer on ESP32-based board to control 16 or more servo motors. Now supporting ESP32, ESP32_S2, ESP32_S3, ESP32_C3-based boards. Tested OK with ESP32 core v2.0.5

This library enables you to use RTC from RP2040-based boards such as Nano_RP2040_Connect, RASPBERRY_PI_PICO. This RP2040-based RTC, using Interrupt, has no battery backup. Time will be lost when powered down. To need NTP-client to update RTC every start-up.

A bare minimum but really fast and simple stepper library for Arduino.

This library enables you to use Interrupt from Hardware Timers on an nRF52-based board. These nRF52 Hardware Timers, using Interrupt, still work even if other functions are blocking. Moreover, they are much more precise than other software timers using millis() or micros(). Now supports `Sparkfun Pro nRF52840 Mini`

Smart library with comprehensive functions for counting (multiple) frequencies and period-times. For Arduino Uno and Zero.
