Cia peb sim
Thaum koj upload cov code, nws yog lub sij hawm los ntsuam xyuas lub Circuit Court! Cov cai hauv Arduino program cuam tshuam nrog cov sensors siv lawv cov tsev qiv ntawv, uas tso cai rau nws nyeem cov ntaub ntawv sensor thiab teeb tsa ntau yam kev teeb tsa ntawm cov sensors. Tom qab ntawd nws luam tawm cov ntaub ntawv sensor hla qhov chaw nres nkoj serial. LED yog siv los qhia tias Circuit Court ua ib yam dab tsi. Qhov no txhais tau hais tias lub LED ntsais txhua lub sij hawm lub voj muaj nuj nqi khiav, qhia tias cov cai yog nquag nyeem sensor qhov tseem ceeb.
Kev piav qhia ua haujlwm
Cov cai yog qhov tseem ceeb ntawm qhov kev ua haujlwm ntawm Circuit Court. Yog li, cia peb nkag siab cov cai:.
- Ua ntej, nws suav nrog ntau lub tsev qiv ntawv los cuam tshuam nrog cov sensors:
- "I2Cdev.h" thiab "MPU6050.h" yog cov tsev qiv ntawv rau MPU6050 6-axis accelerometer/gyroscope sensor
- "Adafruit_BMP085.h" yog lub tsev qiv ntawv rau BMP085 barometric siab sensor.
- "HMC5883L_Simple.h" yog lub tsev qiv ntawv rau HMC5883L magnetometer sensor.
- Tom qab ntawd nws tsim cov khoom thoob ntiaj teb rau peb lub sensors: MPU6050 accelgyro, Adafruit_BMP085 bmp, thiab HMC5883L_Simple Compass.
- Tom ntej no, nws txhais qee qhov sib txawv los khaws cov txiaj ntsig ntawm qhov ntsuas, xws li ax, ay, thiab az rau lub accelerometer ntawm MPU6050 thiab mus rau lub taub hau rau lub magnetometer ntawm HMC5883L. Thiab nws txhais lub LED_PIN tas li thiab qhov sib txawv ntawm blinkState.
- Lub teeb () muaj nuj nqi pib kev sib txuas lus serial thiab pib I2C kev sib txuas lus. Tom qab ntawd nws pib pib peb lub sensors:
- Lub BMP085 sensor yog pib los ntawm kev hu pib () txoj kev. Yog tias qhov no rov qab tsis tseeb, qhia tias tsis tuaj yeem pom lub sensor, qhov kev zov me nyuam nkag mus rau lub voj tsis kawg thiab luam tawm cov lus yuam kev hla qhov chaw nres nkoj serial.
- Lub MPU6050 sensor yog pib los ntawm kev hu rau tus txheej txheem initialize() thiab xyuas seb nws puas ua haujlwm raug. Thiab nws teeb lub I2C bypass enabled rau MPU6050.
- HMC5883L sensor yog pib los ntawm kev hu rau qee qhov haujlwm, xws li SetDeclination, SetSamplingMode, SetScale, thiab SetOrientation, rau kev teeb tsa sib txawv rau lub sensor.
- Hauv lub voj () muaj nuj nqi, cov cai nyeem cov ntaub ntawv los ntawm peb lub sensors thiab luam tawm nws tawm ntawm qhov chaw nres nkoj serial:
- Nws nyeem qhov kub, siab, qhov siab, thiab siab ntawm hiav txwv theem los ntawm lub sensor.
- Nws nyeem raw acceleration thiab gyroscope ntsuas los ntawm MPU6050 sensor.
- Nws nyeem cov nqe lus los ntawm HMC5883L sensor, uas yog lub kaum sab xis ntawm cov kev taw qhia uas lub sensor yog taw tes thiab cov kev taw qhia uas sib nqus sab qaum teb.
- Thaum kawg, nws ntsais lub LED los qhia txog kev ua haujlwm thiab tos ib pliag ua ntej rov nyeem cov sensors.
