Cov Arduino Uno board tsuas muaj ib qho xwb I2C module, tab sis nws muab cov SDA thiab SCL kab ntawm ob qhov chaw sib txawv. Nco tseg: Thaum sib txuas lus nrog cov cuab yeej siv I2C kev sib txuas lus raws tu qauv, rub-up resistors yuav tsum tau siv.
Tib neeg kuj nug, Arduino puas muaj i2c?
Hlau Library The Arduino Vim muaj ob I2C / TWI interfaces SDA1 thiab SCL1 nyob ze rau AREF tus pin thiab qhov ntxiv yog nyob ntawm tus pins 20 thiab 21.
Tsis tas li, muaj pes tsawg i2c li tuaj yeem txuas nrog Arduino? Raws li txoj cai, mus txog 128 - qhov txwv ntawm qhov tshwj xeeb I2C chaw nyob. Tag nrho I2C cov khoom siv tau txuas nyob rau hauv parallel, thiab ib khub ntawm 4.7K pullup resistors coj SCL & SDA kab siab. Tsim & tsim hluav taws xob circuits rau ntau tshaj 25 xyoo.
Kuj Paub, puas Arduino Nano txhawb i2c?
Cov Arduino Nano muaj ntau qhov chaw rau kev sib txuas lus nrog lub computer, lwm qhov Arduino , los yog lwm yam microcontrollers. Lub tsev qiv ntawv SoftwareSerial tso cai rau kev sib txuas lus ntawm ib qho ntawm cov Nano cov digital pins. ATmega 328 tseem txhawb I2C (TWI) thiab SPI kev sib txuas lus.
Qhov twg siv i2c raws tu qauv?
I2C yog serial raws tu qauv rau ob-xaim interface los txuas cov khoom siv qis qis xws li microcontrollers, EEPROMs, A / D thiab D / A converters, I / O interfaces thiab lwm yam khoom siv zoo sib xws hauv cov tshuab kos. Nws tau tsim los ntawm Philips thiab tam sim no nws yog siv los ntawm yuav luag tag nrho cov tuam txhab loj IC.
