Chifukwa chake, kuti alole ogwiritsa ntchito kugwiritsa ntchito CAN-basi mosavuta, mawonekedwe amtundu wa serial amasunthidwa pafupi ndi mawonekedwe a CAN frame, ndipo chiyambi ndi mapeto a chimango amatchulidwa mu serial frame, ndiko kuti, "mutu wa chimango" ndi "mapeto a chimango" mu lamulo la AT. , Ogwiritsa ntchito amatha kudzikonza okha. Utali wa chimango umatanthawuza kutalika kuyambira pachiyambi cha chimango mpaka kumapeto kwa deta yomaliza, osaphatikizapo mapeto a sikelo. Zambiri zamafelemu zimagawidwa m'mafelemu otalikirapo ndi mafelemu okhazikika. Chimango chokhazikika chimakhazikitsidwa ngati 0x00, ndipo chimango chotalikirapo chimakhazikitsidwa ngati 0x80, chomwe ndi chosiyana ndi kutembenuka kowonekera komanso kutembenuka kowonekera ndi chizindikiritso. Mu kusintha kwa protocol, mosasamala kanthu za kutalika kwa deta komwe kuli m'munda wa data wa chimango chilichonse Mochuluka bwanji, zomwe zili mu chidziwitso cha chimango zimakhazikika. Pamene mtundu wa chimango ndi chimango chokhazikika (0x00), ma byte awiri otsiriza a mtundu wa chimango amaimira ID ya chimango, ndi dongosolo lapamwamba poyamba; pamene chidziwitso cha chimango ndi chimango chotambasula (0x80), ma byte 4 omaliza amtundu wa chimango amayimira ID ya chimango, pomwe kusanja kwapamwamba koyamba
    Zindikirani: M'matembenuzidwe amtundu wa protocol, mosasamala kanthu za kutalika kwa data zomwe zili mu gawo la data la chimango chilichonse, zomwe zili muzithunzi zimakhazikika. Imakhazikitsidwa ngati chimango chokhazikika (0x00) kapena chimango chowonjezera (0x80). ID ya chimango iyenera kugwirizana ndi mtundu wa ID, apo ayi ID ikhoza kukhala yolakwika.
  • Sinthani uthenga wa CAN kukhala serial frame
    Uthenga wa basi ya CAN umalandira furemu kenako n'kutumiza chithunzi. Gawoli lidzasintha zomwe zili m'munda wa data wa CAN motsatana, ndipo nthawi yomweyo yonjezerani mutu wa chimango, kutalika kwa chimango, chidziwitso cha chimango ndi deta ina ku chigawo cha serial, chomwe chiridi chithunzithunzi chojambula Chotsani mawonekedwe amtundu wa CAN.
    Sinthani mauthenga a CAN kukhala mafelemu otsatizana
    Kutembenuka exampLe:
    Seri frame to CAN message (custom protocol).
    CAN masinthidwe magawo osinthidwa mu example.
    Kutembenuka: makonda protocol, chimango mutu AA, chimango mapeto: FF, kutembenuka kwa njira: bidirectional.
    Chidziwitso cha Frame: Palibe chifukwa chokonzekera, Mtundu wa chimango: Palibe chifukwa chokonzekera, deta isanayambe komanso itatha kutembenuka ili motere. CAN meseji ku serial frame: mawonekedwe obwerera kumbuyo kwa uthenga wa CAN.
