TaskScheduler library

Cooperative multitasking for Arduino, Teensy and esp8266 microcontrollers

Version 3.0 - 2017, 2018 (Latest news here)

A lightweight implementation of cooperative multitasking (task scheduling) supporting:

• Periodic task execution (with dynamic execution period in milliseconds or microseconds)
• Number of iterations (n times)
• Execution of tasks in predefined sequence
• Dynamic change of task execution parameters (frequency, number of iterations, callback function)
• Power saving via entering IDLE sleep mode between tasks are scheduled to run
• Event-driven task invocation via Status Request object
• Task IDs and Control Points for error handling and watchdog timer
• Local Task Storage pointer (allowing use of same callback code for multiple tasks)
• Layered task prioritization
• Support for std::functions (ESP8266 and ESP32 only)
• Support for overall Task timeouts
• Static and dynamic callback method binding
• Support for STM32F1 ARM Cortex-M3 boards
