H3LIS331DL, yog lub zog qis ua tau zoo 3-axis linear accelerometer koom nrog "nano" tsev neeg, nrog digital I²C cov lej sib txuas. H3LIS331DL muaj cov neeg siv xaiv tau cov nplai ntawm g 100g/± 200g/± 400g thiab nws muaj peev xwm ntsuas qhov nrawm nrog cov ntaub ntawv tso tawm tus nqi los ntawm 0.5 Hz txog 1 kHz. H3LIS331DL tau lees tias ua haujlwm dhau qhov ntsuas kub ntev los ntawm -40 ° C txog +85 ° C.

Hauv qhov kev qhia no peb yuav los qhia txog kev cuam tshuam ntawm H3LIS331DL nrog cov duab me me.

Kauj Ruam 1: Yuav Tsum Kho Vajtse:

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

1. H3LIS331DL

2. Particle Photon

3. I2C Cable

4. I2C ntaub thaiv npog rau particle photon

Kauj ruam 2: Khoos phis tawj sib txuas:

Tshooj khoos phis tawj sib txuas ntu piav qhia qhov txuas txuas txuas uas xav tau ntawm lub sensor thiab cov duab photon. 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:

H3LIS331DL 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 3: Txoj Cai rau Kev Ntsuas Kev Ntsuas:

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:

#suav nrog

#suav nrog

// H3LIS331DL I2C chaw nyob yog 0x18 (24)

#define Ntxiv 0x18

int xAccl = 0, yAccl = 0, zAccl = 0;

void teeb tsa ()

{

// Teem sib txawv

Particle.variable ("i2cdevice", "H3LIS331DL");

Particle.variable ("xAccl", xAccl);

Particle.variable ("yAccl", yAccl);

Particle.variable ("zAccl", zAccl);

// Pib I2C kev sib txuas lus li MASTER

Hlau.begin ();

// Pib kev sib txuas lus txuas, teeb tsa tus nqi = 9600

Serial.begin (9600);

// Pib I2C Kev Kis

Wire.beginTransmission (Addr);

// Xaiv tswj npe 1

Hlau.write (0x20);

// Pab kom X, Y, Z axis, lub zog rau hom, cov ntaub ntawv tso tawm tus nqi 50Hz

Hlau.write (0x27);

// Nres I2C Kev Kis

Wire.endTransmission ();

// Pib I2C Kev Kis

Wire.beginTransmission (Addr);

// Xaiv tswj npe 4

Hlau.write (0x23);

// Teeb tsa qhov ntsuas tag nrho, +/- 100g, hloov kho tas li

Hlau.write (0x00);

// Nres I2C Kev Kis

Wire.endTransmission ();

ncua (300);

}

void lub voj ()

{

unsigned int cov ntaub ntawv [6];

rau (int i = 0; i <6; i ++)

{

// Pib I2C Kev Kis

Wire.beginTransmission (Addr);

// Xaiv cov ntaub ntawv sau npe

Hlau.write ((40 + i));

// Nres I2C Kev Kis

Wire.endTransmission ();

// Thov 1 byte ntawm cov ntaub ntawv

Wire.requestFrom (Addr, 1);

// Nyeem 6 bytes ntawm cov ntaub ntawv

// xAccl lsb, xAccl msb, yAccl lsb, yAccl msb, zAccl lsb, zAccl msb

yog (Wire.available () == 1)

{

cov ntaub ntawv = Wire.read ();

}

ncua (300);

}

// Hloov cov ntaub ntawv

int xAccl = ((data [1] * 256) + data [0]);

yog (xAccl> 32767)

{

xAccl -= 65536;

}

int yAccl = ((cov ntaub ntawv [3] * 256) + cov ntaub ntawv [2]);

yog (yAccl> 32767)

{

yAccl -= 65536;

}

int zAccl = ((cov ntaub ntawv [5] * 256) + cov ntaub ntawv [4]);

yog (zAccl> 32767)

{

zAccl -= 65536;

}

// Tso tawm cov ntaub ntawv rau dashboard

Particle.publish ("Acceleration in X-Axis is:", String (xAccl));

Particle.publish ("Acceleration in Y-Axis is:", String (yAccl));

Particle.publish ("Acceleration in Z-Axis is:", String (zAccl));

ncua (300);

}

Particle.variable () muaj nuj nqi tsim cov kev hloov pauv kom khaws cov zis tawm ntawm lub sensor thiab Particle.publish () muaj nuj nqi qhia cov zis ntawm lub dashboard ntawm lub xaib.

Cov zis sensor tau pom hauv daim duab saum toj no rau koj siv.

Kauj Ruam 4: Cov ntawv thov:

Accelerometers zoo li H3LIS331DL feem ntau pom nws daim ntawv thov hauv kev ua si thiab tso saib qhov hloov pauv profile. Qhov ntsuas qhov ntsuas no tseem ua haujlwm hauv kev tswj hwm lub zog zoo rau kev siv mobile. H3LIS331DL yog triaxial digital acceleration sensor uas tau suav nrog lub ntse ntawm-nti cov lus tsa suab cuam tshuam kev tswj hwm.
