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 20:00a9a95ef083 3 has its own time of repetition. To execute this, a Ticker was used to call a function every 12.5 mSec.
muaiyd 20:00a9a95ef083 4 In this software a benefit is a token from two counter, one is counting a pulses and it reset every 8 cycles.
muaiyd 20:00a9a95ef083 5 That mean it reset every 100 mSec. Then other counter (AllTimeCounter) increased by one. Every slot in the 8 slots
muaiyd 20:00a9a95ef083 6 has a defined function, for example the slot number 1 is to reading the two digital input. however this slote is
muaiyd 20:00a9a95ef083 7 for this function it is not excuted every slot 1. It excute just when the timer calculat 400 mSec. That is 4X8
muaiyd 20:00a9a95ef083 8 cycles. Also, after 8X8 cycles (800 mSec) the condition is true for two factions, but the processor will
muaiyd 20:00a9a95ef083 9 implement one in slot 1 and next cycle implement the other.
