9.2 UKUGUQULWA OKUNGABANYE NGE-ID
Ukuguqulwa okungafihli nge-ID kuwukusetshenziswa okukhethekile kokuguqulwa okusobala okusiza abasebenzisi ekwakheni amanethiwekhi wabo ngendlela elula kakhudlwana futhi basebenzise izimiso eziyisisekelo zohlelo lokusebenza.
Le ndlela iguqula ngokuzenzakalelayo ulwazi lwekheli lusuka kuhlaka lwe-serial luye ku-ID yozimele yebhasi le-CAN. Ngokwazisa isiguquli mayelana nekheli lokuqala kanye nobude baleli kheli kuhlaka lomkhiqizo ngesikhathi sokucushwa, isiguquli sikhipha le ID yozimele bese siyiguqulela kunkambu ye-ID yozimele yomlayezo we-CAN. Lokhu kusebenza njenge-ID yomlayezo we-CAN lapho udlulisela phambili lolu hlaka lomkhiqizo. Lapho uguqulela umlayezo we-CAN uwenze ifremu yeserial, i-ID yomlayezo we-CAN iphinde ihunyushwe endaweni efanele ngaphakathi kohlaka lwe-serial. Kubalulekile ukuqaphela ukuthi, kule modi yokuguqulwa, isilungiselelo se-“CAN ID” kokuthi “Izilungiselelo zepharamitha ye-CAN” yesofthiwe yokulungiselela ayivumelekile. Lokhu kungenxa yokuthi, kulesi simo, isihlonzi esidlulisiwe (i-ID yohlaka) sigcwaliswa kusukela kudatha engaphakathi kohlaka lomkhiqizo olushiwo ngenhla.
9.2.1 UHLAKA LWE-UART ONGAKWAZI
Ngemva kokuthola uhlaka lwedatha ye-serial oluphelele, isiguquli siyidlulisela ngokushesha ebhasini le-CAN.

I-ID ye-CAN ethwelwe ngaphakathi kohlaka lwe-serial ingasethwa ngaphakathi kokucushwa, icacise ikheli layo lokuqala nobude ngaphakathi kohlaka lwe-serial. Ububanzi bekheli lokuqala busuka ku-0 kuye ku-7, kanti ubude busuka ku-1 kuye ku-2 kozimele abajwayelekile kanye no-1 kuye ku-4 kumafreyimu anwetshiwe.
Phakathi nokuguqulwa, ngokusekelwe kuzilungiselelo ezilungiselelwe ngaphambilini, wonke ama-ID wozimele we-CAN ngaphakathi kozimele we-serial ahunyushwa ngokuphelele kunkambu ye-ID yozimele yomlayezo we-CAN. Uma inombolo yama-ID ozimele ngaphakathi kozimele we-serial ingaphansi kwenombolo yama-ID ozimele ngaphakathi komlayezo we-CAN, ama-ID asele ngaphakathi komlayezo we-CAN agcwaliswa ngokulandelana kwe-ID1 kuya ku-ID4, enye esele igcwaliswe ngokuthi “0”. Yonke enye idatha iba nokuguqulwa okulandelanayo njengoba kuboniswe kumdwebo.
Uma uhlaka olulodwa lomlayezo we-CAN lungakuqedi ukuguqulwa kwedatha yozimele we-serial, i-ID efanayo iyaqhubeka nokusetshenziswa njenge-ID yozimele yomlayezo we-CAN kuze kube yilapho lonke uhlaka lwe-serial luguqulwa ngokuphelele.
