Operation nyaya

Iyo yakanyanya kukwana uye yakarurama mhinduro yeMCU kuverenga kona yegineti ndiyo SPI interface.

Imwe Dhidhiyo SPI maitiro, unidirectional - 3 waya
Iyo AS5048-AB inogona kubatana zvakananga kune indasitiri yakajairwa SPI chiteshi che microcontroller. Iyo shoma yekubatanidza inodiwa yekutaurirana unidirectional (angle + alarm values ​​kuverenga) pakati peiyo microcontroller neAS5048 ndeye MISO, SCK, SS/.
Iyo kona ichaverengwa pane yega yega 16-bit SPI kutamiswa. Ona AS5048 tafura yerejista yedatare, kunyoresa 3FFFh.

Mufananidzo 5: Kushandisa iyo SPI Interface unidirectional ine microcontroller

Imwe mudziyo SPI modhi, bidirectional - 4 waya
Kana mamwe marejista kunze kwemakona chete maitiro anofanirwa kuverengwa, kana kuti kunyora marejista muAS5048, chiratidzo MOSI chinodiwa.

Mufananidzo 6: Kushandisa iyo SPI Interface bidirectional ine microcontroller

Multi zvishandiso SPI Daisy cheni modhi
Iyo AS5048 inogona kuve daisy yakasungwa, uchishandisa 4 waya chete kune SPI kutaurirana.
Mukugadzirisa uku nenx encoders, kutevedzana kuchagadziriswa sezvinotevera:

• MCU inogadza SS/ = 0
• MCU inochinja nx 16-bit (eg VERENGA murairo FFFFh) kuburikidza neketani
• MCU inoisa SS/=1
  Panguva iyoyo ese ma nx encoders agamuchira iyo VERENGA murairo FFFFh.
• MCU inoisa SS/=0
• MCU inochinja nx 16-bit (semuenzaniso NOP command 0000h)
• MCU inoisa SS/=1
  Panguva iyoyo iyo nx 16-bit yakagamuchirwa paMISO ndiwo nx angle values.

Mufananidzo 7: Multi Devices muDaisy chain mode

Firmware coding

Iyo inotevera sosi kodhi inokodzera iyo 4-Wire application
Basa risina spiReadData () rinoverenga / rinonyora maitiro mana kubva kuAS4

• Tumira murairo VERENGA AGC / Gamuchira kukosha kusingazivikanwe
• Tumira murairo VERENGA MAG / Gamuchira kukosha AGC
• Tumira murairo VERENGA Angle / Gamuchira kukosha MAG
• Tumira murairo NOP (hapana kushanda) / Gamuchira kukosha ANGLE

Kana VERENGA ANGLE chete ichidikanwa muchiuno, maitiro anogona kudzikiswa kuita mutsara mumwe:

• Tumira murairo VERENGA Angle / Gamuchira kukosha kweAngle
  The function static u8 spiCalcEvenParity(ushort value) ndeyekusarudza, inoverengera parity bit ye16-bit SPI rukova.
