1euroFilter
1.0.0
Géry Casiez
Algorithm to filter noisy signals for high precision and responsiveness.
The 1€ filter uses a first order low-pass filter with an adaptive cutoff frequency: at low speeds, a low cutoff stabilizes the signal by reducing jitter, but as speed increases, the cutoff is increased to reduce lag. The algorithm is easy to implement, uses very few resources, and with two easily understood parameters, it is easy to tune. In a comparison with other filters, the 1€ filter has less lag using a reference amount of jitter reduction.

Khoi Hoang
This library enables you to use ISR-based PWM channels on AVR ATmega164, ATmega324, ATmega644, ATmega1284 with MCUdude MightyCore, to create and output PWM any GPIO pin
It now supports 16 ISR-based PWM channels, while consuming only 1 Hardware Timer. PWM channel interval can be very long (ulong microsecs / millisecs). The most important feature is they're ISR-based PWM channels, supporting lower PWM frequencies with suitable accuracy. Their executions are not blocked by bad-behaving functions or tasks. This important feature is absolutely necessary for mission-critical tasks. These ISR-based PWMs, still work even if other software functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software-based PWM using millis() or micros(). That's necessary if you need to control devices requiring high precision. Now you can change the PWM settings on-the-fly

Save battery energy by slowing the clock and/or switching off un-needed modules in the microcontroller.
For ATmega168P/328P/1284P/2560 and ATtiny44/84/45/85 based projects, especially breadboard Arduinos. Don't use analogRead()? Power-off the internal analog-to-digital converter (ADC). Not using Serial or Wire or SPI? Power-off the internal USART, SPI, TWI or USI hardware blocks. Power them back on again when you do need them. Waiting around but can't sleep the processor? Slow down the system clock - the AVR uses a quarter the power at 1 MHz compared to 16 MHz. NOTE: Use Narcoleptic or LowPower for the big battery savings: sleeping the microcontroller. And remove the power LED. This library is for that final percent of battery life. C++ alternative to avr/power.h.

Michael Sims
BlockNot gives you non-blocking timers with simplicity.
*** Added feature to compensate for unwanted rapid succession triggers when using a high speed microcontroller such as a Raspberry Pi Pico. Stop using delay() in your code because it stops the execution of your code until the timer has finished. BlockNot's design focus is always SIMPLICITY and COMMON SENSE. It uses common sense terms which simplifies the reading and writing of your code. It offers, among several things, convenient AND SIMPLE timer functionality, but most of all ... it gets you away from blocking methods, like delay() - as a means of managing events in your code. Non-Blocking is the proper way to implement timing events in Arduino code and BlockNot makes it easy while also offering the ability to branch your code using many different references to time.

This library enables you to use Hardware-based PWM channels on Generic boards to use PWM to control continuous Stepper Motor
The most important feature is they're purely hardware-based PWM channels, supporting very high PWM frequencies. Therefore, their executions are not blocked by bad-behaving functions or tasks. This important feature is absolutely necessary for mission-critical tasks. These hardware-based PWMs, still work even if other software functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software-based PWM using ISR, millis() or micros(). That's necessary if you need to control devices requiring high precision

Coil, Current Transformer (CT) based AC current measurements using fast ADC sampling of waveform
Mesure currents, iRMS and similar with a current transformer or coil. Requires a simple bias circuit that ensures that the votlages fed to the ADC is swinging around a certain dc-offset; and this is then ran through a resistor to turn the current into a voltage. Actual curernt measurement is then made by fast sampling the waveform. Assumes relatively slow AC curernts (few 100Hz), such as typical household mains power supplies (50hz, 60hz)

This library can be used to limit the first and second derivative of a variable as it approaches a target value.
Its easiest to think of in terms of position, velocity, and acceleration. If used with a servo, for example, the servo will smoothly move to a target value with a trapezoidal velocity profile. The formula in this program supports being run at uneven intervals, and allows for editing the target, position, and velocity while it runs since it does not rely on calculating a motion profile ahead of time.

This important feature is absolutely necessary for mission-critical tasks. These hardware-based PWMs, still work even if other software functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software-based PWM using ISR, millis() or micros().

Dynamixel_Servo
2.1.0
Michael Krzyzaniak
Dynamixel_Servo is an Arduino compatible library for controlling Dynamixel MX and RX series servos.
This module presents a high-level interface and a low-level interface for manipulating the servo's registers. The high-level interface looks up the width (one or two bytes) of the specified value and manipulates all relevant registers (low byte and high byte) as a single value. The high-level interface also performs automatic conversions between the raw values defined in the servo's datasheet, and physical values such as radians, radians-per-second, Amperes, Volts, baud, microseconds, degrees-Celcius, percent (of the motor's maximum torque) etc... as appropriate to the value. The down-side is that the high-level interface hogs several kilobytes of code space, as the result of using floating-point math and having some large-ish lookup tables. Therefore a low-level interface is provided that allows more straightforward access to the servo's registers using raw values, which may optionally be converted to and from physical values using the provided functions. Using the low-level interface and raw values may save several kilobytes of code space (The compiler won't compile functions that aren't used). The low-level interface also provides the capability to access several of the servo's values in a single command using the xxx_raw_page functions.

This library enables you to use Interrupt from Hardware Timers on ESP32-based (including ESP32_S2, ESP32_S3 and ESP32_C3) boards
These ESP32 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 software timers using millis() or micros(). That is mandatory if you need to measure some data requiring better accuracy. 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 are 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.

ESP8266TimerInterrupt
1.6.0
Khoi Hoang
This library enables you to use Interrupt from Hardware Timers on an ESP8266-based board.
These ESP8266 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 software timers using millis() or micros(). That's mandatory if you need to measure some data requiring better accuracy. 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.

ESP_EEPROM
2.2.1
j-watson
An improved EEPROM library for ESP8266
The ESP8266 family doesn't have genuine EEPROM memory so it is normally emulated by using a section of flash memory. With the standard library, the sector needs to be re-flashed every time the changed EEPROM data needs to be saved. For small amounts of EEPROM data this is very slow and will wear out the flash memory more quickly. This library writes a new copy of your data when you save (commit) it and keeps track of where in the sector the most recent copy is kept. The flash sector only needs to be erased when there is no more space for copies in the flash sector. You can keep track of this yourself to do a time-consuming erase when most convenient or the library will do it for you when there is no more space for the data when you commit it.

Useful if the EEPROM is not available or too small. Currently, ATSAMD21 and ATSAMD51 are supported (and consequently every board based on this cpu like the Arduino Zero, Aduino MKR1000, Nano-33 IoT, Itsy-Bitsy M4, etc).

This library is for the Great Lunar Expedition for Everyone mission, which will provide accessible opportunities for students to directly participate in Lunar exploration.
GLEE will educate, inspire and enable the next generation of explorers with its easy to use LunaSat platform. GLEEs LunaSats, post-it note size wireless enabled sensing nodes, offer a range of functionalities relevant to both Lunar and Earth based scientific investigations. GLEE believes that providing students with LunasSats and associated education content will foster deep learning of many STEM fundamentals. Furthermore, challenging students to identify investigations which utilize standalone and networked LunaSats will foster novel crowdsourced approaches to Lunar exploration while also promoting innovations beneficial to life on Earth. The major goal of GLEE is to deliver and disperse 500 student team owned LunaSats as part of a distributed environmental sensing network on the surface of the moon. The prototyping of LunaSat and creation of educational modules is funded by NASAs Artemis Student Challenge initiative.

Itty Bitty
1.5.0
Tom Biuso

With the fastest possible Arduino-compatible GPIO and register manipulation...
It's the biggest of hits when you need to bang bits!


Getting tired of mindlessly staring down your wristwatch in an open-mouthed gape, awaiting a digitalRead's return? Do you long for a super-simple way to set or flip your bits? Has repeatedly ALT-TABing to the ATmega datasheets to look up register descriptions worn you down to the last raw nerve?

Then, golly gee, this lib is here to allay your despair!

In fact, it was made for you - whether an Arduino n00b, hopelessly ignorant to the time their programs waste on the simplest IO tasks, or an AVR guru and uber-smart embedded god, who never even gave a thought to seeking an easier way to bang bits. Most of all, however, this library is for the wretched, cursed signals stuck in the maze of your Arduino's buffers. For it is they who fly through pin lines at the speed of light only to quietly suffer the most indignant fate at the hands of non-performant source code: WAITING.

So set those bits free with a little help from your friends - a plenitude of easy-to-use functions, macros, and data structures in this simple, elegant library that will give your code real legs. But, more importantly, it makes coding that much more FUNNER.

A lightweight library for serial-port interaction: send commands and get/set sketch variables via a JSON- and Python-compatible text interface.
In one line, and usually with less than a microsecond of overhead, keyhole.variable("foo", foo); provides serial-port access to an integer, floating-point or String variable in your sketch. Set its value by sending foo=123\n - the variable() method will return true to let the sketch know when you do this. Query it by sending foo\n . Query all exposed variables at once by sending ?\n , or choose to have them auto-report themselves periodically. Responses are in easy-to-parse JSON format and can be turned into Python dicts with one call to ast.literal_eval(), but there's a plotter-compatibility mode too. For the computer's side of the interaction, a complementary Python module is included in the project repository (or available separately as keyhole-comm on PyPI).

LCD_HD44780
1.0.0
ZulNs
A library for HD44780 based LCDs.
This library using only 4-bits databus to save MCU I/O pins along with RS, EN, and RW pins. It has ability to edit some text right on the LCD screen, eg. insert and delete a character, backspace, move cursor in all directions (left, right, up, and down), newline, line home, and line end. It also supports println() method, read character or text right from the LCD screen (no longer need to waste some expensive MCU RAMs to buffering the text currently being edited). So you can edit your text on the screen without messing with complex code. All used I/O pins, except EN pin, are shareable with other hardware. For example if it used with a matrix keypad, then the databus pins (DB4, DB5, DB6, and DB7) can be shared with the keypad column only or the row pins only. Do not share them with mixed any column and row pins together to avoid unexpected behaviour on accessing the LCD while a key is being pressed.

Luni
0.9.1
Doug Johnson
Implements a framework for device drivers for use on the Arduino.
The traditional role of device drivers as an abstraction layer is a very useful one and can be applied in the Arduino environment to bundle device access into a logical, standard, easy to access API. Each device driver includes methods for open, read, write, and close of logical unit instances that represent target device instances. The target device can be physical, virtual, or a combination of the two.

Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software ISR-based PWM, using millis(), micros() or Timer Interrupt.

The first and only Arduino library where MG811 Gas Sensor combine with Data Science
This library calculates the ppm values of CO2, C2H5OH, CO, CH4 (the primary gases), and Theoretical CO2 using analog data obtained from the MG811 gas sensor. Concentrations of the primary gases are determined by applying the cathodic reaction correction coefficient over 20-second intervals, along with the effects of temperature and humidity on the a and b parameters of the ppm values. Theoretical CO2, on the other hand, is derived from a polynomial curve created based on the Nernst equation. Additionally, the library supports Python-based data science applications, including 4D ppm concentration graph simulations at 20-second intervals and a 4D ppm slope estimation platform for advanced data analysis.

MQTT Client
1.0.2
Andreas Motzek
MQTT Client lets you connect to a MQTT broker and publish strings to a topic.
First create a MQTTClient. You have to pass a task list from Cooperative Multitasking, a client (e.g. WiFiClient from WiFi101), host, port and credentials of the MQTT broker. Then create a MQTTTopic. Use the MQTTClient and the topic name as arguments when doing that. To connect to the broker call MQTTClient::connect(). After that you can call MQTTTopic:publish("...") to publish a string. Requires Cooperative Multitasking for processing the acknowledgement packets of the broker. So you have call CooperativeMultitasking::run() in your loop() function. See the examples for details.

Only two types of messages are parsed, $GPGGA (and its GNSS versions $GNGGA, $GLGGA, and $GAGGA) and $GPRMC (and its GNSS versions $GNRMC, $GLRMC, and $GARMC). From these two NMEA sentences MicroNMEA can output date, time, latitude, longitude, altitude, number of satellites used, horizontal dilution of precision (HDOP), course and speed. When other NMEA sentences are detected they can be passed to an optional callback function for decoding or logging. Checksum failures can be indicated with another optional callback function.

Arduino library for driving up to 768 (49152 ESP32, PICO) LEDs, signals, sound modules or other actuators via one signal line on a model railway


New in release 3.5.0: support LichtMaschine Pico Zero hardware, multiplexer support multiple LED channels, speed up application startup
  • Excel user interface to configure the LEDs without programming at all improved by the engagement of Pattern Configurator and Program Generator!
  • On the basis of WS2811 / WS2812 devices (RGB LEDs), many different effects can easily be controlled via one wire:
    • Animated lighting effects: animated house, soft blending light signals and crossing lights, traffic lights, flashing vehicle lights, construction site security lights, street lamps, funfair effects, disco, photo flash, ...
    • Sounds: 1 Eu sound modules could generate: station announcements, railroad noises, animal sounds, ...
    • Movements With additional hardware servo or stepper motors could be controlled in the same way.
  • Easy cabling: For a model railway the simple wiring is very important. A single 4-pin ribbon cable can supply all consumers on the layout. With multiple plug strips, the LEDs can be flexibly arranged.
  • Thanks to many examples, no programming knowledge is necessary. Anyone who can operate a text editor is able to adapt these examples to the individual circumstances.
  • Other features: very low cost, configurable animation sequences, high update rate, reading of 80 and more switches, logical operations, automatic and manual operation (light dependent, timed, CAN bus, random)...
  • Hardware: The "extras" directory contains schematics and printed circuit boards for this library.

This project would not have been possible without the fantastic FastLED library. => Thank you zackees & jueff

From there you place code you want to run in a if statement that checks the update(). If the time for the delay has passed, update will return true. You are also able to run a function in place of an if statement block using a void function and adding it when creating the MyDelay object. You can also set a maximum number of times the timer will repeat. The default is to repeat forever.

This library enables you to use Interrupt from Hardware Timers on an NRF52-based board using mbed-RTOS such as Nano-33-BLE.
These nRF52 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 software timers using millis() or micros(). That is mandatory if you need to measure some data requiring better accuracy. 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 are 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.

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 (certainly depending on clock frequency accuracy) than other software timers using millis() or micros(). That is mandatory if you need to measure some data requiring better accuracy. 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 are 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.

Rop Gonggrijp
Receiving/analysing/sending on-off-keying signals for radio remote controls 📱, weather stations 🌦️ and more.
OOKwiz is an ESP32 Arduino library for receiving, analysing, decoding, encoding and transmitting On/Off keyed signals using a number of radios via RadioLib as well as a generic type. Radio plugins easy to build. Not just a library, also a versatile rx/tx OOK Swiss army knife. Used in a sketch that only calls the library's `setup()` and `loop()` functions, it prints output like below for received signals and provides a command line interpreter to set radio type, GPIO-pins used, etc. Settings are stored in flash on the ESP32 using SPIFFS. OOKwiz tries to read the data from messages, example: `pulse(5906) + pwm(timing 190/575, 24 bits 0x1772A4)` (all time in µs). That same format is among those accepted by the CLI `transmit` function, so on-the-fly experimentation is super-easy: just copy the string, change a few bits and transmit it back out.

Nadav Matalon
PCA9536 RGB LED Driver
This library provides an API for controlling a single RGB Led (Common-Cathode or Common-Anode) via the I2C Bus. Communication between the Arduino (master) and the RGB Led (slave) is handled by the PCA9536, a 4-Channel I2C GPIO (General Purpose I/O) Expander. The basis of the current API comes from the PCA9536 Library (https://github.com/nadavmatalon/PCA9536), which is expanded here to include the relevant functions, including: Turning on a specific color (or all colors) on and off, Toggling a color, and an independent Blinking functionality for each color which doesn't make use of delays and therefore does not interrupt other routines running simultaniously in the code.

PIRSensor
1.1.0
Dean Gienger
PIRSensor provides a class to control a Passive Infrared sensor.
These sensors measure IR radiation from an object such as a human and can be used to detect presense of warm objects such as a person or animal. A common example is an AM312 or an HC-SR501. These sensors typically have three terminals - VCC, GND, and OUT. When the PIR sensor detects a presence - meaning it detects the heat generated by a warm body within it's range, it will set the output "open" - so if you have a pull-up resistor, the waveform will be at 0v when nothing is detected and 3.3v when something is detected.

Jan Breuer
Port of the C/C++ "SCPI Parser" library by Jan Breuer, suitable for advanced C/C++ programmers. For a much simpler solution in your Arduino projects, consider the Vrekrer SCPI Parser library.
SCPI Parser for advanced programmers or instrumentation engineers. Tested only on Teensy 4.1 board. Fails to compile for Arduino Uno/Nano due to missing strtoull() in stdlib.h. Port of the C/C++ SCPI Parser library by Jan Breuer. Aims to provide parsing ability of SCPI commands on instrument side. SCPI parser library is based on these standards: SCPI-99, IEEE 488.2-2004. This Arduino port was made by downloading SCPI Parser's most recent GitHub version as of March 4, 2023, so that recent C++ fixes were included. SCPI Parser (C/C++) git version was 4e87990. This is therefore not actually version 2.2.0, but slightly ahead of that version.

SDConfigCommand can read standardised text files stored on a SD card, parse and tokenise them into commands and values. The library can also write over existing settings but it is currently slow to do so. For every line on the config file this library reads, it will callback a user-specified function. The user can access the current command and values, then decide the next action, such as verifying commands and storing values in variables. With regards to writing over existing settings, user can choose one command, and the library will search for the command in the config file and replace the whole setting line with a new value. The library does not add or remove settings.

Possible output pins are pin 2, 3, 5, 6, 7, 8, 44, 45 and 46.
Unlike the original Servo.h library, this library does not use Timer1.
The advantage here is that when using the Wire.h library no fluctuations in the pulse width occur.
In addition, I / O registers are addressed directly and not via the digitalWrite()-function (as in Servo.h).

ShiftRegGPIOXpander_AVR
3.1.0
Gabriel D. Goldman
Add as many output pins as needed, as this library manages extending GPIO outputs (GPIO Expander) by using simple and economic shift registers (SIPO). Designed for 74HCx595 SIPO shift registers.
Simplifies extending GPIO outputs by usage of simple and economic shift registers (SIPO shift registers), designed for the 74HCx595. The library takes care of keeping the shift register output pins updated transparently to the user by implementing an API analog to the Arduino digitalRead() and digitalWrite() functions (and adding a digitalToggle()-kind method as present in other platforms). In addition an extended API adds methods to manipulate one or several pins outputs simultaneously: set or reset all the pins in a single call, set or reset pins through a bitmask, etc. The library provides a mechanism to create 'virtual ports' that can handle a subset of contiguous pins, allowing the user to treat them as a single entity, for 1 to 16 pins long segments.

SoftWire is a software I2C implementation for Arduino and other Wiring-type environments. It utilises the pinMode(), digitalWrite() and digitalRead() functions. The pins to be used for the serial data (SDA) and serial clock (SCL) control lines can be defined at run-time. Alternatively it is possible to pass references to functions which read and control the SDA and SCL lines, thereby allowing direct port manipulation to be used if preferred. Multiple objects (for multiple software I2C buses) and clock-stretching by slave devices are supported. A timeout feature is included to prevent lockups by faulty or missing hardware. The microcontroller must function as the master device, multiple masters are not supported. GNU LGPL v2.1.

TankController
25.1.1
Kirt Onthank , James Foster , Preston Carman
Software for the Arduino that controls pH and temperature in the Open-Acidification project.
As mankind adds substantial additional carbon dioxide (CO2) to the atmosphere, as much as one third of that CO2 is absorbed is absorbed by the ocean. This CO2 reacts with water to create carbonic acid, and afterwards further products, which makes the ocean water more acidic. This process is known as ocean acidification. Over the next century ocean water is predicted to become 2.5 times more acidic. It is imperative that we understand how ocean acidification will impact marine organisms and ecosystems. Because the oceans contain over 99% of the habitable space on earth, and much of the planet’s biodiversity this will be a massive undertaking. Unfortunately, the equipment needed to perform ocean acidification research is expensive, restricting this work to a relatively few well-funded labs. The goal of the Open Acidification Project is to create inexpensive open-source tools to conduct ocean acidification research and ultimately greatly increase the amount of quality ocean acidification research that can be accomplished.

The most important feature is they are purely hardware-based PWM channels, supporting very high PWM frequencies. Therefore, their executions are not blocked by bad-behaving functions or tasks. This important feature is absolutely necessary for mission-critical tasks. These hardware-based PWMs, still work even if other software functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software-based PWM using ISR, millis() or micros(). That is necessary if you need to control devices requiring high precision. New efficient setPWM_manual function to facilitate waveform creation using PWM

It now supports 16 ISR-based PWM channels, while consuming only 1 Hardware Timer. PWM channel interval can be very long (ulong microsecs / millisecs). The most important feature is they're ISR-based PWM channels, supporting lower PWM frequencies with suitable accuracy. Their executions are not blocked by bad-behaving functions or tasks. This important feature is absolutely necessary for mission-critical tasks. These ISR-based PWMs, still work even if other software functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software-based PWM using millis() or micros().

This library enables you to use Interrupt from Hardware Timers on an Arduino, Adafruit or Sparkfun AVR board, such as Nano, UNO, Mega, Leonardo, YUN, Teensy, Feather_32u4, Feather_328P, Pro Micro, 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 are 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.

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 software timers using millis() or micros(). That is mandatory if you need to measure some data requiring better accuracy. It now supports 16 ISR-based Timers, while consuming only 1 Hardware Timer.

Paul Stoffregen
Makes coding responsive sketches easier.
When using delay(), your code can not (easily) respond to user input while the delay is happening (unless you use interrupts or complex timer code). This library makes this easy by allowing you to create variables (objects) that automatically increase as time elapses. It is easy to check if a certain time has elapsed, while your program performs other work or checks for user input.

fast_samd21_tc
0.3.1
Daniel Mohr
TC3, TC4 or TC5 timer library for SAMD21 microcontrollers.
This library allows using the TC3_Handler, TC4_Handler and the TC5_Handler routine triggered by the 16-bit Timer/Counter TC3, TC4 or TC5 on SAMD21 (e. g. Arduino MKRZERO). It is also possible to use TC4 and TC5 as a 32-bit Timer/Counter. It is possible to trigger very fast (a few microseconds, e. g. 4 us and less, depending on the runtime of the handler routine/function). You can use fraction numbers as interval (e. g. 2.5 us). Keep in mind, TC4 and TC5 are not completely independent. But you can use TC4 and TC5 together as a 32-bit counter. This 32-bit counter allows to call the interrupt with a time between calls up to 1 day and more.

The most important feature is they're purely hardware-based PWM channels, supporting very high PWM frequencies. Therefore, their executions are not blocked by bad-behaving functions or tasks. This important feature is absolutely necessary for mission-critical tasks. These hardware-based PWMs, still work even if other software functions are blocking. Moreover, they are much more precise (certainly depending on clock frequency accuracy) than other software-based PWM using ISR, millis() or micros(). That's necessary if you need to control devices requiring high precision. New efficient setPWM_manual function to facilitate waveform creation using PWM. Supporting MegaCoreX.

Michael Uray
Arduino library to easily use on/off delays and cycle timers with non-blocking functions.
The library provides a simple on/off delay for digital signals or a cycle timer which creates a periodically output. It keeps track of the elapsed time since the start of the delay or cycle and is non-blocking. The current time gets stored on a change of the input for the delayOnOff() functions to compare it with the given delayOn or delayOff delay times. The cycle functions restart themself without any external input and these create a permanent on/off signal (e.g. blinking LED) or just on trigger cycle (eg. start periodically actions).

Library to emulate PS2 keyboard/mouse using arduino
Library to emulate PS2 keyboard/mouse using arduino. In this version i've fixed timing to improve reliability. I've integrated some keyboard protocol basics directly to library, so user don't need to do that. I plan the same for mouse protocol. API is still subject to change in future, because i want to make it bit more convenient to use. Also i plan to add some rudimentary interrupt driven mode as optional feature.

Dejwk
Allows scheduling delayed and/or repetitive tasks.
Works on boards that support C++ standard library (e.g. Espressif ESP32 family). Specifically, it requires the following standard headers: ``, ``, and ``. Uses `std::priority_queue` for storage, and therefore: (1) Maintains the queue in a flat vector, and thus, does not dynamically reallocate memory as long as the queue remains below its present capacity. (In most practical cases, the queue will stay within small bound capacity); (2) Scheduling a task, as well as looking up the nearest scheduled task, is O(log N), where N is the queue length, so it remains fast even in those rare cases when the queue gets longer. The tasks can be defined as function pointers, but also as inline lambdas, or generally as arbitrary callables, so it is convenient and idiomatic to make them stateful.
