9.2 UKUGUQULELA ENGASEKHO ENE-ID
Uguqulo oluselubala olune-ID lusetyenziso olukhethekileyo loguqulo oluselubala oluququzelela abasebenzisi ekwakheni uthungelwano lwabo ngokulula ngakumbi kunye nokusebenzisa iiprothokholi zezicelo zesiko.
Le ndlela iguqula ngokuzenzekelayo ulwazi lwedilesi ukusuka kwisakhelo sothotho kwisakhelo se-ID yebhasi ye-CAN. Ngokwazisa umguquli malunga nedilesi yokuqala kunye nobude bale dilesi kwisakhelo sothotho ngexesha loqwalaselo, umguquleli ukhupha le ID yesakhelo kwaye ayiguqulele kwisakhelo se-ID yesakhelo somyalezo we-CAN. Oku kusebenza njenge-ID yomyalezo we-CAN xa uthumela phambili olu thotho lwesakhelo. Xa uguqulela umyalezo we-CAN kwisakhelo sothotho, i-ID yomyalezo we-CAN ikwaguqulelwa kwindawo efanelekileyo ngaphakathi kwesakhelo sothotho. Kubalulekile ukuqaphela ukuba, kule ndlela yokuguqula, i-"CAN ID" yokuseta kwi-"CAN Parameter Settings" ye-software yoqwalaselo ayisebenzi. Oku kungenxa yokuba, kule meko, isazisi esigqithisiweyo (i-ID yefreyimu) ifakwe kwidatha engaphakathi kwesakhelo sothotho esikhankanywe ngasentla.
9.2.1 ISIKHOKELO SE-UART OKUYA KUKHONA
Emva kokufumana isakhelo sedatha epheleleyo, umguquli uyithumela ngokukhawuleza kwibhasi ye-CAN.

I-ID ye-CAN eqhutywe ngaphakathi kwesakhelo se-serial inokusetwa ngaphakathi kobumbeko, ichaza idilesi yayo yokuqala kunye nobude ngaphakathi kwesakhelo se-serial. Uluhlu lwedilesi yokuqala luvela kwi-0 ukuya kwi-7, ngelixa ubude buvela kwi-1 ukuya kwi-2 yezakhelo eziqhelekileyo kunye ne-1 ukuya kwi-4 kwizakhelo ezongeziweyo.
Ngexesha loguqulo, ngokusekwe kwizicwangciso eziqwalaselweyo, zonke ii-ID ze-CAN zesakhelo ngaphakathi kwesakhelo sothotho ziguqulelwe ngokupheleleyo kumhlaba wesakhelo se-ID yomyalezo we-CAN. Ukuba inani lee-ID zesakhelo ngaphakathi kwesakhelo sothotho lingaphantsi kwenani lee-ID zesakhelo ngaphakathi komyalezo we-CAN, ii-ID eziseleyo ngaphakathi komyalezo we-CAN zizaliswe ngolandelelwano lwe-ID1 ukuya kwi-ID4, enye eseleyo izaliswe ngo-“0”. Enye idatha iguqulelwa ngokulandelelana njengoko kubonisiwe kumzobo.
Ukuba isakhelo somyalezo we-CAN esinye asilugqibi uguqulo lwedatha yesakhelo sothotho, i-ID efanayo iyaqhubeka isetyenziswa njengesakhelo se-ID yomyalezo we-CAN de yonke isakhelo sothotho siguqulwe ngokupheleleyo.
