Hauv lub ntiaj teb niaj hnub no, ntau dua ib nrab ntawm cov tub ntxhais hluas thiab menyuam yaus nyiam ua si thiab txhua tus neeg uas nyiam nws, txaus siab los ntawm cov txuj ci ntawm kev ua si paub qhov tseem ceeb ntawm kev nkag siab zoo hauv qhov no. Peb kuj tseem xav tsis thoob los ntawm tib yam thiab tsuas yog coj nws mus rau ntawm cov laug cam, peb xav txog kev ua haujlwm ntawm lub ntsuas hluav taws xob ntsuas hluav taws xob uas tuaj yeem ntsuas tus nqi ib leeg ntawm ib yam khoom. Yog li, lub ntsuas ntsuas peb tau coj los daws cov haujlwm yog BMG160. BMG160 yog 16-ntsis, digital, triaxial, gyroscope sensor uas tuaj yeem ntsuas tus lej nyob hauv peb chav nyob ib puag ncig.

Hauv qhov kev qhia no, peb yuav los qhia txog kev ua haujlwm ntawm BMG160 nrog Particle Photon.

Kho vajtse uas koj yuav xav tau rau lub hom phiaj no yog raws li hauv qab no:

1. BMG160

2. Particle photon

3. I2C Cable

4. I2C Shield rau Particle Photon

Kauj Ruam 1: BMG160 Txheej Txheem:

Ua ntej tshaj plaws peb xav paub koj nrog cov yam ntxwv tseem ceeb ntawm lub ntsuas qhov ntsuas uas yog BMG160 thiab cov txheej txheem kev sib txuas lus uas nws ua haujlwm.

BMG160 yog qhov tseem ceeb 16-ntsis, digital, triaxial, gyroscope sensor uas tuaj yeem ntsuas tus nqi kaum. Nws muaj peev xwm suav tus lej nyob hauv peb chav nyob ib puag ncig, x-, y- thiab z-axis, thiab muab cov cim teeb tsa sib xws. Nws tuaj yeem sib tham nrog raspberry pi board siv I2C kev sib txuas lus raws tu qauv. Cov qauv tshwj xeeb no tau tsim los kom tau raws li qhov xav tau rau cov neeg siv khoom siv nrog rau lub hom phiaj kev lag luam.

Cov txheej txheem kev sib txuas lus uas lub sensor ua haujlwm yog I2C. I2C sawv cev rau kev sib koom ua ke. Nws yog cov txheej txheem kev sib txuas lus uas kev sib txuas lus tau tshwm sim los ntawm SDA (cov ntaub ntawv xov xwm) thiab SCL (cov xov tooj). Nws tso cai txuas ntau yam khoom siv tib lub sijhawm. Nws yog ib qho ntawm cov txheej txheem kev sib txuas lus yooj yim tshaj plaws thiab muaj txiaj ntsig tshaj plaws.

Kauj Ruam 2: Yam Koj Xav Tau..

Cov ntaub ntawv uas peb xav tau kom ua tiav peb lub hom phiaj suav nrog cov khoom siv hauv qab no:

1. BMG160

2. Particle Photon

3. I2C Cable

4. I2C Shield Rau Particle Photon

Kauj Ruam 3: Khoos Phis Tawj Hookup:

Tshooj khoos phis tawj sib txuas ntu piav qhia qhov txuas txuas txuas uas xav tau ntawm lub sensor thiab Particle. Ua kom muaj kev sib txuas raug yog qhov tseem ceeb xav tau thaum ua haujlwm ntawm ib qho system rau qhov xav tau cov zis. Yog li, qhov xav tau kev sib txuas yog raws li hauv qab no:

BMG160 yuav ua haujlwm dhau I2C. Nov yog qhov piv txwv kab hluav taws xob daim duab, qhia txog yuav ua li cas xaim txhua lub interface ntawm lub sensor.

Tawm-ntawm-lub thawv, lub rooj tsavxwm tau teeb tsa rau I2C interface, zoo li peb pom zoo siv qhov kev sib txuas no yog tias koj tsis ntseeg lwm yam.

Txhua yam koj xav tau yog plaub lub xov hlau! Tsuas yog plaub qhov kev sib txuas xav tau Vcc, Gnd, SCL thiab SDA tus pin thiab cov no txuas nrog kev pab ntawm I2C cable.

Cov kev sib txuas no tau qhia hauv cov duab saum toj no.

Kauj Ruam 4: 3-Axis Gyroscope Measurement Particle Code:

Cia peb pib nrog cov lej me me tam sim no.

Thaum siv lub ntsuas qhov ntsuas nrog arduino, peb suav nrog application.h thiab lub tsev qiv ntawv spark_wiring_i2c.h. "application.h" thiab lub tsev qiv ntawv spark_wiring_i2c.h muaj cov haujlwm uas pab txhawb kev sib txuas lus i2c ntawm lub sensor thiab cov khoom me me.

Tag nrho cov cai hauv qab no tau muab rau hauv qab no kom yooj yim ntawm tus neeg siv:
