Task Scheduler
Cooperative multitasking for Arduino microcontrollers
Version 2.6.1: 2018-03-15
OVERVIEW:
A lightweight implementation of cooperative multitasking (task scheduling) supporting:
- Periodic task execution, with dynamic execution period in
milliseconds
(default) ormicroseconds
(if explicitly enabled) – frequency of execution - Number of iterations (limited or infinite number of iterations)
- Execution of tasks in predefined sequence
- Dynamic change of task execution parameters (frequency, number of iterations, callback methods)
- Power saving via entering IDLE sleep mode when tasks are not scheduled to run
- Support for event-driven task invocation via Status Request object
- Support for task IDs and Control Points for error handling and watchdog timer
- Support for Local Task Storage pointer (allowing use of same callback code for multiple tasks)
- Support for layered task prioritization
- Support for
std::functions
(ESP8266
only) - Overall task timeout
Scheduling overhead: between 15
and 18
microseconds per scheduling pass (Arduino UNO rev 3 @ 16MHz
clock, single scheduler w/o prioritization)
TaskScheduler was tested on the following platforms:
- Arduino Uno R3
- Arduino Nano
- Arduino Micro
- ATtiny85
- ESP8266 (Node MCU v2.0)
- ESP32
- Teensy (tested on Teensy 3.5)
