muaiyd 18:f485d46a7acb 1 /* Cyclic Executive
muaiyd 16:0a2138a18f26 2 This software is built to test (Cyclic Executive). Five main functions are used in and every one of them
muaiyd 16:0a2138a18f26 3 has its own time of repetition. To execute this, a Ticker was used to call a function every 100 mSec.
muaiyd 16:0a2138a18f26 4 In other words, when 100 mSec is passed, the Cycle function is called and so on every 100 mSec. In this
muaiyd 16:0a2138a18f26 5 software a benefit is a token place for the difference between a float division with integer one. For example
muaiyd 16:0a2138a18f26 6 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
muaiyd 16:0a2138a18f26 7 result every 4 cycle (400 mSec) the condition be true and calling the function. Also, after 8 cycles (800 mSec)
muaiyd 16:0a2138a18f26 8 the condition is true for two factions, but the processor will implement on the priority that it was put in
muaiyd 16:0a2138a18f26 9 the program.
