/* This software is built to test (Cyclic Executive). Five main functions are used in and every one of them has its own time of repetition. To execute this, a Ticker was used to call a function every 100 mSec. In other words, when 100 mSec is passed, the Cycle function is called and so on every 100 mSec. In this software a benefit is a token place for the difference between a float division with integer one. For example float(Counter/4.0)-Counter/4 if the Counter is a real repetition of 4 so the result of this will be 0. As a result every 4 cycle (400 mSec) the condition be true and calling the function. Also, after 8 cycles (800 mSec) the condition is true for two factions, but the processor will implement on the priority that it was put in the program. */ #include "Function.h" uint16_t Counter=0; void CycleFunction(); int main(){ Init_LCD(); InitFile(); LogTimer.start(); //Call the CycleFunction every 100 msec Cycle.attach(&CycleFunction,0.1); } void CycleFunction(){ TickerPin=!(TickerPin); Counter++; if((float(Counter/4.0)-Counter/4)==0) ReadDigitalin(); if((float(Counter/8.0)-Counter/8)==0) ReadAnalogin(); if((float(Counter/10.0)-Counter/10)==0) FreqMsur(); if((float(Counter/15.0)-Counter/15)==0) BinaryCounter(); if((float(Counter/18.0)-Counter/18)==0) InputCheck(); if((float(Counter/20.0)-Counter/20)==0) Display(); if((float(Counter/50.0)-Counter/50)==0) LogFile(); //The least common multiple for all the above is 1800 cycles // so every 180 Sec all the functions are repeated if(Counter==1800) Counter=0; }
