Applied PLC's Technique, Concept, and Function to Microcontroller is named "Applied Microcontroller Programming" and shared my Libraries "MicroBeaut" with you.
- Debounce
- TimerOn (Timer On)
- TimerOff (Timer Off)
- TimePulse (Time Pulse)
- Blink
- Trigger
- SR (Set Dominant)
- RS (Reset Dominant)
- Toggle
- Rising (Rising Edge)
- Falling (Falling Edge)
- TimeSchedule (Schedule execution at specified time intervals)
- ScanSchedule (Schedules execution after a certain number of scans)
All of them are generic functions that can help you do Microcontroller Programming efficiently.
Timer Group used "micros()" of Arduino function for calculating elapsed time. As I call " Continuous" tasks, you can use them for multitasking programs. Still, don't forget a delay() function; you may sometimes require to use it as an initiative of some process.
Bistable and Edge Group are essential functions to detect or turn bit On / Off. Without thinking about managing their program, you can use these libraries in your program.
The Schedule is a choice for your to execute your subroutine by Time or Scans.
I hope you will enjoy Microcontroller Programming and hope these libraries may help you manage your program easily.
The debounce function delays TimeDebounce from the rising edge and falling edge of input to the output's rising edge and falling edge.
The rising edge of the input starts the timer. While the input is TRUE, after a delay of duration TimeDebounce, the timer changes the output to TRUE. The falling edge of the input starts the timer. While the input is FALSE, after a delay of duration TimeDebounce, the timer changes the output to FALSE.

outputState ^= (inputState & !prevInput); // Toggle Output
digitalWrite(LED_BUILTIN, outputState); // Write Output
}The timer on function delays TimeDelay from the input's rising edge to the output's rising edge.
The rising edge of the input starts the timer. While the input is TRUE, after a delay of duration TimeDelay, the timer changes the output to TRUE. If the input changes to FALSE at any time, the timer resets, reversing the result to FALSE and elapsed time to zero.

}The timer off function delays TimeDelay from the input's falling edge to the output's falling edge.
The falling edge of the input starts the timer. While the input is FALSE, after a delay of duration TimeDelay, the timer changes the output to FALSE. If the input changes to TRUE at any time, the timer resets, reversing the result to TRUE and elapsed time to zero.

}The time pulse function generates a pulse of duration TimeDelay starting on the rising edge of the input.
The rising edge of the input starts the timer, setting output to TRUE. While the output is TRUE, the timer ignores the input.

}The input enables blinking. The blink function generates a pulse output that is supposed to repeatedly turn the result on and off. The reset input resets the output to FALSE and initiates the pulse-off period. TimeDelayOn specifies how long the pulse is on; TimeDelayOff specifies how long the pulse is off.

}The trigger function sets the output only one scan.
The rising edge of the input starts the timer. While the input is TRUE, after a delay of duration TimeDelay, the timer changes the output to TRUE and restarts the timer. If the input changes to FASE at any time, the timer holds the last value.
The reset input resets the output to FALSE and resets the timer.
