Ukuqalisa nge-MotionFD ngexesha lokwenyani lelayibrari yokubona ukuwa kwi-X-CUBE-MEMS1 ukwandiswa kwe-STM32Cube

Intshayelelo

I-MotionEC licandelo lelayibrari ye-middleware ye-software ye-X-CUBE-MEMS1 kwaye isebenza kwi-STM3z2. Inika ulwazi lwexesha lokwenyani malunga nokuqhelaniswa nesixhobo kunye nemo yentshukumo esekwe kwidatha esuka kwisixhobo.
Ibonelela ngezi ziphumo zilandelayo: ukuqhelaniswa nesixhobo (i-quaternions, ii-angles ze-Euler), ukujikeleza kwesixhobo (ukusebenza kwe-virtual gyroscope), i-gravity vector kunye ne-linear acceleration.
Eli thala leencwadi lijonge ukusebenza ne-ST MEMS kuphela.
I-algorithm ibonelelwe ngefomathi yethala leencwadi emileyo kwaye yenzelwe ukusetyenziswa kwi-STM32 microcontrollers esekwe kwi-ARM® Cortex®-M0+, i-ARM® Cortex®-M3, i-ARM® Cortex®-M33, i-ARM® Cortex®-M4 kunye ne-ARM® Cortex®-M7 izakhiwo.
Yakhelwe phezulu kwe-STM32Cube itekhnoloji yesoftware ukwenza lula ukuphatheka kuzo zonke ii-STM32 microcontrollers ezahlukeneyo.
Isoftware iza nesampukuphunyezwa kwe-X-NUCLEO-IKS4A1 okanye i-X-NUCLEO-IKS01A3 ibhodi yokwandisa kwi-NUCLEO-F401RE, NUCLEO-U575ZI-Q okanye ibhodi yophuhliso ye-NUCLEO-L152RE.
