IEC-61131 function blocks ported to arduino platform

Control

This is a simple library reproducing IEC-61131 standard function blocks to use with arduino micro-processor or any compatible processor (Atmel AVR, Espressif, STM32, etc.).

Revision History

Version	Comment	Release Date
0.1	Initial commit	Jan 2017
0.2	blink class added	May 2017

Features

The library is in an early stage of development and contains the following classes:

1. trigger: trigger objects can be used for edge detection (rising and/or falling edges)
2. ton: allows to instantiate objects similar to IEC-61131 TON function block
3. tof: allows to instantiate objects similar to IEC-61131 TOF function block
4. ctu: counter up objects can be created using this class
5. ctd: counter down objects can be created using this class
6. blink: blink objects are used to create square signals with configurable time high and time low options (this is a non standard IEC function)

Example

Check the attached examples folder for more details

//declaring a timer off object
tof timer(sensor, 1200000);

//assign timer off output to digital out
digitalWrite(relay, (uint8_t)timer.out());
