An Arduino timer interrupt is a hardware-based timing mechanism that measures precise time intervals. Every microcontroller has a clock oscillator—Arduino Uno operates at 16MHz, determining processing ...

Read time Configure various aspects of the RTC including setting of alarms, countdown timers, periodic time update interrupts, trickle charging, power switchover mode and programmable clock output.

PinChangeInterrupt for a lot of pins Rising, Falling or Change detection for every pin separately Usable on a lot Arduino compatible boards Implementation is fast, compact and resource friendly ...

Interestingly, he uses the Arduino IDE mixed with native ESP-IDF APIs to get the best performance. Like most complex interrupt-driven software, [Ivan’s] code uses a two-stage interrupt strategy.

In this Arduino FreeRTOS tutorial we will cover How RTOS works, some frequently used terms in RTOS, how to install FreeRTOS in Arduino IDE, and then create a FreeRTOS Task.
