Cooperative multitasking for Arduino, ESPx, STM32 and other microcontrollers. A lightweight implementation of cooperative multitasking (task scheduling). An easier alternative to preemptive programming and frameworks like FreeRTOS. You mostly do not need to worry about pitfalls of concurrent processing (races, deadlocks, livelocks, resource sharing, etc.). The fact of cooperative processing takes care of such issues by design.

Usage: - run function blinkLED() every 2000 ms: timer.addEverytime(2000, blinkLED); - run function itWorks() two times with interval 2000 ms, wait 300 ms before first start: timer.addTask(2000, 2, 300, itWorks); Removing a task: removeEverytime(callback_function); removeTask(callback_function); Library can also be used in desktop C++ applications: #include <iostream> #include <string> #include <chrono> #include <thread> #include "RZtimer.h" int main() { RZTimer timer; timer.addEverytime(2000, [] (){ std::cout << "Hello! " << std::chrono::duration_cast<std::chrono::milliseconds >( std::chrono::system_clock::now().time_since_epoch() ).count() << "\n";}); while(1){ timer.run(); std::this_thread::sleep_for(std::chrono::milliseconds(100)); } }

The Project "WDT Driver for LPC1114 on FreeRTOS" was my Project work required for the partial Completion of my Post Graduate Diploma in Embedded System Design at Center for Development of Advanced Computing, Advanced Computing Training School, Pune, India. The Duration of the Project was 15-20 Days wherein we had to develop the driver library for the Watchdog Timer on LPC1114 and incorporate the same into FreeRTOS. The services of the driver are exported using the UNIX like read, write, Open and ioctl system calls used by the various tasks in the FreeRTOS environment to register with the Watchdog service. The Watchdog service itself is a task running as an idle task hook and services the watchdog on behalf of all the tasks that are registered with our driver. ...

The embedded Single Timer Wheel (eSTW) is a timer wheel facility that can be used at task and interrupt level. The number of wheel spokes is user configured. The timer granularity is determined by the task signal or hardware interrupt source.
