I-ams AS5048 14-bit Inzwa Yendawo Ejikelezayo ene-Digital Angle kanye Nokukhiphayo kwe-PWM

i-ams-AS5048-14-bit-Rotary-Position-Sensor-with-Digital-Angle-and-PWM-Output

Ulwazi Lomkhiqizo

I-AS5048 iyinzwa ye-rotary position-14-bit ene-digital angle (interface) kanye nokuphumayo kwe-PWM. Yakhelwe ngabakwa-ams OSRAM Group futhi ishicilelwe ngu Umcibisholo.com. Inzwa isetshenziselwa ukukala indawo yento ezungezayo futhi inikeza izilinganiso ze-engeli ezinembile.
Ibhodi ye-adaptha ye-AS5048 iyisekhethi evumela ukuhlolwa okulula nokuhlolwa kwenzwa ye-AS5048 ngaphandle kwesidingo sokwakha isihluthulelo sokuhlola esihlukile noma i-PCB. Ibhodi le-adaptha linganamathiselwa ku-microcontroller noma i-AS5048-Demoboard njengedivayisi yangaphandle.

Incazelo Yebhodi
I-AS5048 Adapterboard ifaka phakathi uhlobo lwesixhumi esibonakalayo A (SPI) noma B (I2C), izimbobo ezikhwezwayo ezingu-4 x 2.6mm, kanye nesixhumi se-P1. Inikeza indlela elula yokuxhuma nokuxhumana nenzwa ye-AS5048.

Iziyalezo zokukhweza

Ukukhweza ibhodi ye-adaptha ye-AS5048, landela lezi zinyathelo:

  1. Beka uzibuthe wediametric ngaphezulu noma ngaphansi kwenzwa yokuma ye-AS5048.
  2. Qinisekisa ukuthi uzibuthe ugxile phakathi kwephakheji ngokubekezelela okungu-0.5mm.
  3. Gcina i-airgap phakathi kukazibuthe kanye nekhemisi yesishumeki kububanzi obungu-0.5mm ukuya ku-2mm.
  4. Sebenzisa okokusebenza okungeyona i-ferromagnetic njengethusi, ithusi, i-aluminium, noma insimbi engagqwali yesibambi sikazibuthe.

Ukulandela le miyalo kuzoqinisekisa ukusebenza kahle kwebhodi ye-adaptha ye-AS5048 kanye nezilinganiso zokuma ezinembile.

Umlando Wokubuyekeza

Amacala okusebenza

Isixazululo esiphelele nesinembile se-MCU yokufunda i-engeli kazibuthe isixhumi esibonakalayo se-SPI.

Imodi ye-SPI yedivayisi eyodwa, i-unidirectional - izintambo ezi-3
I-AS5048-AB ingaxhunywa ngokuqondile nembobo ye-SPI esezingeni lemboni yesilawuli esincane. Isidingo esincane sokuxhumana sokuxhumana okukodwa (i-angle + alamu yokufundwa kwamanani) phakathi kwe-microcontroller ne-AS5048 yi-MISO, SCK, SS/.
I-engeli izofundwa ekudlulisweni ngakunye kwe-16-bit SPI. Bheka ithebula lerejista yedatha ye-AS5048, rejista 3FFFh.

Umfanekiso 5: Ukusebenzisa i-SPI Interface unidirectional ene-microcontroller

i-ams-AS5048-14-bit-Rotary-Position-Sensor-with-Digital-Angle-and-PWM-Output-7

Imodi ye-SPI yedivayisi eyodwa, i-bidirectional - izintambo ezi-4
Uma amanye amarejista kunamanani e-engeli kuphela okufanele afundwe, noma ukuze ubhale amarejista ku-AS5048, isignali ye-MOSI iyadingeka.

Umfanekiso 6: Ukusebenzisa i-SPI Interface bidirectional ene-microcontroller

i-ams-AS5048-14-bit-Rotary-Position-Sensor-with-Digital-Angle-and-PWM-Output-8

Amadivayisi amaningi we-SPI Daisy chain mode
I-AS5048 ingaboshwa ngamaketanga, kusetshenziswa izintambo ezi-4 kuphela ukuxhumana kwe-SPI.
Kulokhu kulungiselelwa ngezifaki khodi ze-nx, ukulandelana kuzocutshungulwa ngendlela elandelayo:

  • I-MCU ibeka i-SS/ = 0
  • I-MCU ishintsha i-nx 16-bit (isb. FUNDA umyalo FFFFh) ngeketango
  • I-MCU isetha i-SS/=1
    Ngaleso sikhathi zonke izifaki khodi ze-nx zithole umyalo FUNDA FFFFh.
  • I-MCU isetha i-SS/=0
  • I-MCU iyashintsha nx 16-bit (isb umyalo we-NOP 0000h)
  • I-MCU isetha i-SS/=1
    Ngaleso sikhathi i-nx 16-bit etholwe ku-MISO amanani e-engeli angu-nx.

Ikhodi ye-Firmware

Ikhodi yomthombo elandelayo ilingana nohlelo lokusebenza lwe-4-Wire
I-function void spiReadData() ifunda/ibhala amanani angu-4 ukusuka ku-AS5048

  • Thumela umyalo FUNDA i-AGC / Thola inani elingaziwa
  • Thumela umyalo FUNDA MAG / Thola inani le-AGC
  • Thumela umyalo FUNDA I-engeli / Thola inani elithi MAG
  • Thumela umyalo othi NOP (akukho msebenzi) / Thola inani elithi ANGLE

Uma FUNDA I-ANGLE kuphela idingeka ku-loop, inqubo ingancishiswa ibe umugqa owodwa:

  • Thumela umyalo FUNDA I-engeli / Thola i-engeli yenani
    Umsebenzi omile u8 spiCalcEvenParity(inani elifushane) uyazikhethela, ubala ibhithi yokulingana yokusakaza kwe-SPI engu-16-bit.
