I2C qeeb dua tshaj SPI . Piv rau I2C , SPI yog sai dua . I2C rub ntau zog tshaj SPI.

Ib yam li ntawd, tib neeg nug, qhov twg zoo dua i2c lossis SPI?

SPI txhawb kev sib txuas lus nrawm dua puv-duplex thaum I2C qeeb dua. I2C yog pheej yig dua los siv tshaj qhov SPI kev sib txuas lus raws tu qauv. SPI tsuas yog txhawb nqa ib qho khoom siv tswv ntawm lub npav thaum I2C txhawb ntau yam khoom siv tswv. I2C tsis tshua muaj suab nrov tshaj SPI.

Ib yam li ntawd, SPI sai dua UART? Kev sib txuas lus ceev SPI yog qhov tseem ceeb sai dua UART . Qee zaum, ib SPI daws tuaj yeem yog peb zaug sai dua a UART daws.

Xav txog qhov no, yog i2c sai dua serial?

I2C kev sib txuas lus Yog li raws li cov ntaub ntawv no kuv twb xaus lus tias lub ceev tshaj plaws common bitrate siv rau lub xwm txheej Kev sib txuas lus yog 115200 ntsis / s. Qhov no zoo li yog qhov tsawg dua tshaj tus nqi me ntsis rau I2C , uas tshwm sim pib ntawm 100 kbit / s uas sib npaug rau 100000 bits / s.

Qhov txawv ntawm SPI thiab i2c yog dab tsi?

I2C yog lub hauv paus ntawm lub npav CAN. SPI (Serial Peripheral Interface) yog 3-xaim, tag nrho duplex, tus tswv- qhev serial tsheb npav. Lub ntsiab txawv los ntawm I2C yog tias cov kab tau nquag tsav, yog li nws tuaj yeem ua haujlwm ntawm qhov nrawm dua. SPI tsis muaj cov nyiaj siv ua haujlwm lossis lub moos txwv, yog li nws tuaj yeem ua 80 lossis 100 lub sijhawm sai dua I2C.
