Microchip Technology Cov PAB 2515 yog ib tug stand-aloneController Area Network (CAN Bus) maub los uas siv theCAN 2.0B specification. Cov PAB 2515 muaj ob qhov kev lees txais daim npog ntsej muag thiab rau qhov lees txais cov lim dej uas siv los lim tawm cov lus tsis xav tau, yog li txo tus tswv tsev MCU nyiaj siv ua haujlwm.

Ib yam li ntawd, tuaj yeem caij npav hauv Arduino?

Tsheb mus Arduino Kev sib txuas lus: CAN Bus Sniffing thiab tshaj tawm nrog Arduino . Los ntawm Wikipedia, theController Area Network ( YOG ) tsheb npav yog "tsheb tsheb npav tus qauv tsim los tso cai rau microcontrollers thiab cov khoom siv sib txuas lus nrog ib leeg hauv lub tsheb yam tsis muaj lub khoos phis tawj."

Kuj Paub, Canbus module yog dab tsi? Cov CAN Bus module tuaj yeem siv los xa cov ntaub ntawv nruab nrab ntawm cov khoom siv los tsim kev sib txuas lus network. Lub network no. CAN Bus yog multi-master broadcast serial tsheb npav txheem.

Tsis tas li ntawd, cov ntaub ntawv tsheb npav puas tuaj yeem ua tus nqi?

CAN tsheb npav tuaj yeem siv ntau yam baud nqi mus txog 1 Mbit/s. Feem ntau baud nqi yog 125 kbit / s (defaultCANopen) thiab 250 kbit / s (J1939). Cov CAN tsheb npav kev sib txuas lus tsheb npav loads txog li 100% ( cov ntaub ntawv raug xa mus txhua lub sijhawm thiab tag nrho cov nodes ua tau kis), tso cai rau kev siv tag nrho ntawm nominal tus nqi qis.

Tau Max ceev?

Qhov siab tshaj plaws Tsheb npav Ceev Cov ceev tshaj plaws ntawm a YOG tsheb npav, raws li tus qauv, yog 1 Mbit / thib ob. Ib txhia YOG cov tswj yuav txawm li cas los xij tuav siab dua ceev tshaj 1Mbit / xuab zeb yuav raug txiav txim siab rau cov ntawv thov tshwj xeeb. Tsawg- speedCAN (ISO 11898-3, saib saum toj no) ua tau mus txog 125kbit / s.
