MPU9250 yog ib qho ua tau zoo tshaj plaws ua ke Accelerometer, Gyroscope thiab Compass cov ntsuas me me tam sim no muaj. Lawv muaj ntau yam ua tau zoo, suav nrog kev lim qis dhau, tshawb pom cov lus pom, thiab txawm tias cov txheej txheem tshwj xeeb tuaj yeem ua haujlwm tau. Muaj ze li ntawm 130 tus neeg sau npe txawm li cas los xij, nrog ntau qhov chaw, lawv kuj nyuaj heev rau ua haujlwm nrog los ntawm cov cai.

Ob peb lub lis piam dhau los GearBest tau zoo txaus los pub dawb MPU9250 tus qauv los txhawb kev txhawb nqa ntxiv rau nws hauv Visuino. Nws siv 2 lub lis piam ntawm kev ua haujlwm hnyav, tab sis thaum kawg kuv tsis tsuas yog muaj kev txhawb nqa rau MPU9250 siv, tab sis kuv kuj tau ntxiv Kev Ua Kom Ncaj Ncees rau Lub Hloov Hloov, Ua Ntxiv (Thawj thiab Thib Ob Qhov Kev Txiav Txim), thiab Kalman lim dej uas tuaj yeem siv nrog nws txhawm rau txhim kho qhov tseeb

Nov yog thawj qhov kev qhia ntawm MPU9250 kev txhawb nqa tshiab hauv Visuino, thiab nws qhia tau hais tias nws yooj yim npaum li cas los siv nws nrog Visuino. Hauv Cov Lus Qhia hauv qab no kuv yuav qhia koj yuav ua li cas koj tuaj yeem siv Kev Hloov Kho Kom Ncaj Ncees hloov pauv, Ua kom sib haum thiab Kalman lim dej thiab tau txais txiaj ntsig zoo tiag tiag los ntawm koj lub ntsuas qhov ntsuas.
