2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:25

Cov ntaub ntawv no yuav qhia koj yuav siv STM32 MCU +MPU6050 ntsuas lub ntsuas cua gyroscope sensor +lub pob zeb STVC070WT qhov chaw nres nkoj txuas rau DEMO.

STVC070WT yog qhov ua yeeb yaj kiab ntawm peb lub tuam txhab, nws txoj kev txhim kho yog qhov yooj yim, siv tau yooj yim, koj tuaj yeem mus rau lub vev xaib ntawm peb lub tuam txhab rau txhua qhov sib txawv ntawm cov duab:

Kauj Ruam 1: STONE TOOL

Nws tsim nyog sau cia tias peb lub vijtsam txhawb kev sib txuas lus chaw nres nkoj. Qee cov qauv txhawb TTL/RS232/RS485, tab sis qee qhov tsuas yog txhawb RS232. Yog tias koj lub MCU qhov chaw nres nkoj txuas yog TTL qib kev xav, koj yuav tsum ntxiv MAX3232 rau kev hloov pauv qib. Yog tias koj xav paub lub vijtsam twg txhawb nqa TTL thiab uas txhawb nqa TTL thiab RS232, koj tuaj yeem tshawb xyuas nws ntawm peb lub vev xaib:

www.stoneitech.com/product/industrial-type

Peb tuaj yeem pom tias "hom kev lag luam" thiab "hom hom" cov ntxaij vab tshaus feem ntau tsuas yog txhawb RS232 lossis RS485, thiab tsuas yog "hom neeg" cov ntxaij vab tshaus tuaj yeem txhawb nqa TTL/RS232/RS485. Yog koj xaiv "hom qib siab" lossis "yam khoom lag luam", tab sis koj SCM tsuas yog txhawb TTL, tom qab ntawd koj yuav tsum ua qhov hloov pauv hauv qab no:

Lwm cov ntaub ntawv tseem ceeb tuaj yeem pom lossis rub tawm ntawm lub vev xaib raug cai:

Peb cov kauj ruam ntawm STONE display screen development:

Tsim cov duab tso tawm thiab khawm cov laj thawj nrog STONE TOOL software thiab rub tawm cov ntawv tsim tawm mus rau lub teeb pom kev pom. Qhov MCU sib txuas lus nrog STONE zaub module los ntawm cov chaw nres nkoj.

Nrog cov ntaub ntawv tau txais hauv qib 2, MCU ua lwm yam haujlwm.

Kauj Ruam 2: Kev Taw Qhia

Kev qhia ua haujlwm

Qhov kuv yuav qhia koj hnub no yog Demo ntawm lub ntiajteb txawj nqus, gyroscope, Euler Angle, Kev ua haujlwm muaj raws li hauv qab no:

Mpu-6050 lub ntim loj ntawm 4x4x0.9mm (QFN) yog kev hloov pauv hauv kev lag luam. Lwm qhov tshwj xeeb suav nrog cov ntsuas kub hauv tsev thiab oscillators uas sib txawv tsuas yog ± 1% hauv ib puag ncig kev ua haujlwm. Daim ntawv thov

Txawb kev paub ua si augmented kev muaj tiag, EIS: Electronic Image Stabilization (OIS: Optical Image Stabilization) cov neeg siv kev sib tham ntawm cov neeg taug kev taug kev nrog "xoom-kov" piav tes piav taw. Smartphone, ntsiav tshuaj, khoom siv game game, game console, 3D chaw taws teeb tswj, lub tshuab nqa tau yooj yim, UAV, tsheb sib npaug.

Yam ntxwv

Cov zis tawm ntawm 6-lossis 9-axis kev sib hloov matrix, quaternion, Euler Angle forma fusion calculus cov ntaub ntawv. 3-axis angular velocity sensor (gyroscope) nrog 131 LSBs/ °/ SEC rhiab heev thiab tag nrho daim phiaj pom ntau yam ntawm ± 250, ± 500, ± 1000 thiab ± 2000 °/ SEC. Nws tuaj yeem tswj tau los ntawm txoj haujlwm, thiab thaj tsam tswj hwm qhov program yog ± 2g, ± 4g, ± 8g, thiab ± 16g. Tshem tawm qhov rhiab heev ntawm tus tsuj roj thiab lub gyroscope axis thiab txo qhov cuam tshuam ntawm Cov Chaw thiab cov cuab yeej txav mus los. DMP (Digital Motion Processing) lub cav txo lub nra ntawm cov txheej txheem fusion nyuaj, ua kom pom kev sib xws, hnov lub cev, thiab lwm yam. Cov lus tsa suab ua cov ntaub ntawv txhawb nqa lub sijhawm ua haujlwm sib txawv thiab sib nqus sensor kho qhov ua haujlwm hauv, Linux, thiab Windows. Kev ntsuas kub nrog cov zis digital thiab cov tswv yim digital Sync tus pin txhawb cov duab hluav taws xob duab ntxoov ntxoo theem ruaj khov thev naus laus zis thiab GPS programmable tswj cuam tshuam kev txhawb nqa taw tes, co, zoom hauv thiab tawm ntawm daim duab, dov, nqis qis qis cuam tshuam, high-g cuam tshuam, xoom suab hnov, kov qhov hnov, co hnov qhov. Qhov muab qhov hluav taws xob ntawm VDD yog 2.5v ± 5%, 3.0v ± 5%thiab 3.3v ± 5%. Txoj haujlwm tam sim no ntawm VDDIO yog 1.8v ± 5%: 5mA; Standby tam sim no ntawm lub gyroscope: 5uA; Kev ua haujlwm nrawm tam sim no: 350uA, lub zog txuag hluav taws xob tam sim no: 20uA@10Hz I2C hauv hom nrawm txog 400kHz, lossis SPI tus tswv tsev sib txuas mus txog 20MHz lub tshuab hluav taws xob tsim hluav taws xob ntau ntawm qhov kub tsuas yog ± 1% zaus sib txawv. Qhov tsawg kawg nkaus thiab ntim tsawg tshaj plaws (4x4x0.9mm QFN) txiav rau cov khoom lag luam tau raug kuaj kom tau raws li RoHS thiab ib puag ncig tus qauv. Txog tus pin

SCL thiab SDA txuas rau IIC interface ntawm MCU, los ntawm qhov uas MCU tswj MPU6050. Kuj tseem muaj IIC interface, AXCL, thiab XDA, uas tuaj yeem siv los txuas cov khoom siv qhev sab nraud, xws li cov ntsuas hluav taws xob sib nqus, los tsim lub cuaj-axis sensor. VLOGIC yog qhov hluav taws xob ntawm IO chaw nres nkoj, thiab tus lej qis tshaj tuaj yeem ncav cuag 1,8v wb. Feem ntau, peb tuaj yeem siv VDD. AD0 ncaj qha yog tus pin chaw nyob tswj los ntawm IIC interface (txuas nrog MCU), uas tswj qhov kev xaj qis tshaj ntawm IIC chaw nyob. Yog GND txuas nrog, tom qab ntawv IIC chaw nyob ntawm MPU6050 yog 0X68 thiab 0X69 yog VDD txuas nrog. Nco tseg: qhov chaw nyob ntawm no tsis muaj qhov xaj qis tshaj ntawm kev xa cov ntaub ntawv (qhov kev xaj qis tshaj yog siv rau kev nyeem thiab sau ntawv). Hauv qab no yog mpu-6050 module kuv siv:
