Kev ua haujlwm
Standalone PWM tso zis hom
Lub teeb liab PWM (JP2 tus pin #7) tso cai rau ntsuas 12-ntsis qhov tsis txaus ntseeg tus nqi hauv ib tus ncej khub (2.0mm). Tus nqi yog encoded rau hauv pulse dav modulated teeb liab nrog 1µs mem tes dav ib kauj ruam thiab 5V mem tes voltage tuaj yeem txuas nrog kev ntes / timer input ntawm microcontroller txhawm rau txiav txim siab lub kaum sab xis tus nqi.
Qhov tseeb serial tso zis suav los ntawm 0….4095 nyob rau hauv ib tug ncej khub ib tug repeats nrog rau txhua tus ncej tom ntej.
PWM tso zis pib nrog lub mem tes dav ntawm 1µs, nce lub mem tes dav nrog txhua kauj ruam ntawm 0.488µm thiab ncav cuag qhov siab tshaj plaws pulse dav ntawm 4097µs kawg ntawm txhua tus ncej. Saib AS5311 datasheet kom paub meej ntxiv ntawm PWM tso zis.

Siv lub serial interface nrog MCU
Qhov kev daws teeb meem zoo tshaj plaws rau MCU los nyeem lub kaum sab xis ntawm cov hlau nplaum yog qhov sib txuas sib txuas.
Tus nqi 12 me ntsis ntawm lub kaum sab xis yuav raug nyeem ncaj qha, thiab qee qhov kev ntsuas raws li cov ntaub ntawv sib nqus lub zog lossis lub tswb ntsuas tuaj yeem nyeem tib lub sijhawm.
Kev sib txuas ntawm MCU thiab lub rooj tsav xwm adapter tuaj yeem ua nrog 3 xov hlau.
3-xaim serial interface
Lub Serial interface tso cai rau cov ntaub ntawv kis tau tus mob ntawm 12-ntsis cov ntaub ntawv tawm ntawm txoj haujlwm (hauv ib tus ncej khub = 2.0mm). Cov ntaub ntawv khoom D11: D0 sawv cev rau cov ntaub ntawv txoj haujlwm nrog kev daws teeb meem ntawm 488nm (2000µm / 4096) ib kauj ruam. CLK yuav tsum siab ntawm qhov poob ntawm CSn.
Yog tias CLK qis ntawm qhov poob ntawm CSn, thawj 12 cov khoom sawv cev rau cov ntaub ntawv loj, uas yog proportional rau lub zog sib nqus.
