Detailed Description

Simple periodic task scheduler for embedded and Arduino environments.

This class provides a lightweight, non-blocking scheduler for executing a callback function at a fixed interval (in milliseconds). It is designed for use in embedded systems and Arduino sketches, where you want to perform periodic tasks (such as sensor readings, status updates, or control actions) without blocking the main loop.

Features

• Works with Arduino (uses millis()) and desktop (uses std::chrono)
• Non-blocking: call run() regularly to trigger the callback at the right time
• Easy to start, stop, and change the callback
• Suitable for cooperative multitasking and periodic polling

Usage Example

void myTask(void*) {}
Scheduler sched;
sched.begin(1000, myTask); // Call myTask every 1000 ms
// In your main loop:
while (true) {
  sched.run();
  // ... other code ...
}

Methods

• begin(repeatMs, callback): Start the scheduler with interval and callback
• end(): Stop the scheduler
• setCallback(callback): Change the callback function
• run(): Check and execute the callback if interval elapsed

Applications

• Periodic sensor polling
• Status LED blinking
• Timed control actions
• Cooperative multitasking in embedded systems
