muaiyd 18:f485d46a7acb 1 /* Cyclic Executive
muaiyd 21:0e681d5fa3ba 2 This software is built to test (Cyclic Executive). 6 main tasks are used in and every one of them
muaiyd 21:0e681d5fa3ba 3 has its own time of repetition. To execute this, a Ticker was used to call a function every 4 mSec.
muaiyd 21:0e681d5fa3ba 4 In this software a benefit is a token from two counter, one is counting a pulses and it reset every 25 cycles.
muaiyd 21:0e681d5fa3ba 5 That mean it reset every 100 mSec. Then other counter (AllTimeCounter that count a 100 mSec) increased by one.
muaiyd 21:0e681d5fa3ba 6 A slot is defined for each function, for example the slot number 1 is to reading the two digital input. however
muaiyd 21:0e681d5fa3ba 7 this slote is for this function it is not excuted every slot 1. It is excuted just when the timer calculat 400 mSec.
muaiyd 21:0e681d5fa3ba 8 That is 100 cycles. Also, after 200 cycles (800 mSec) the condition is true for two factions, but the processor will
muaiyd 21:0e681d5fa3ba 9 implement one in slot 1 and next cycle implement the other. Excuting the LCD and writing file got more slote space.
muaiyd 21:0e681d5fa3ba 10 The LCD show slot is 72 mSec and the writing is 8 mSec. At A Sec 180 all functions are called and the 1800 (100 mSec)
muaiyd 21:0e681d5fa3ba 11 will be like this:
