Kufotokozera Kwambiri
AS5510 ndi sensa ya Hall yokhala ndi 10 bit resolution ndi mawonekedwe a I²C. Imatha kuyeza malo amtheradi akuyenda kofananira kwa maginito osavuta a 2-pole. Kukonzekera kofananira kukuwonetsedwa pansipa (Chithunzi 1).
Kutengera kukula kwa maginito, sitiroko yofananira nayo ya 0.5 ~ 2mm imatha kuyeza ndi mipata ya mpweya mozungulira 1.0mm. Kuti musunge mphamvu, AS5510 ikhoza kusinthidwa kukhala yotsika mphamvu ikapanda kugwiritsidwa ntchito.

Kuyika board ya AS5510 Adapter
AS5510-AB imatha kukhazikitsidwa pamakina omwe alipo ndi mabowo ake anayi okwera. Maginito osavuta a 2-poles oyikidwa pamwamba kapena pansi pa IC atha kugwiritsidwa ntchito.
Chithunzi 4:
AS5510 adaputala board kukwera ndi kukula kwake
The pazipita yopingasa ulendo amplitude zimadalira mawonekedwe a maginito ndi kukula kwake ndi mphamvu ya maginito (maginito zinthu ndi airgap).
Pofuna kuyeza kayendedwe ka makina ndi yankho laling'ono, mawonekedwe a maginito pa airgap yokhazikika ayenera kukhala ngati pa Chithunzi 5:.
M'lifupi mwake m'lifupi mwake mwa maginito pakati pa mapolo a Kumpoto ndi Kumwera kumatsimikizira kukula kwaulendo wa maginito. Zochepa (-Bmax) ndi zopambana (+Bmax) za maginito zamtundu wa mzere ziyenera kukhala zochepa kapena zofanana ndi chimodzi mwazinthu zinayi zomwe zilipo pa AS5510 (register 0Bh): Sensitivity = ± 50mT, ± 25mT, ±18.5mT , ± 12.5mT Regista ya 10-bit yotulutsa D[9..0] OUTPUT = Field(mT) * (511/Sensitivity) + 511.
Ili ndiye vuto labwino: mzere wa maginito ndi ± 25mT, womwe umagwirizana ndi ± 25mT sensitivity setting ya AS5510. Kusintha kwa kusamuka motsutsana ndi mtengo wotulutsa ndikoyenera.
Max. Mtunda Woyenda TDmax = ±1mm (Xmax = 1mm)
Sensitivity = ±25mT (Register 0Bh ← 01h)
Bmax = 25mT
→ X = -1mm (= -Xmax) Munda(mT) = -25mT OUTPUT = 0
→X = 0mm Munda(mT) = 0mT OUTPUT = 511
→ X = +1mm (= +Xmax)
Munda(mT) = +25mT OUTPUT = 1023
Kutulutsa kwamphamvu kopitilira ±1mm: DELTA = 1023 - 0 = 1023 LSB
Resolution = TDmax / DELTA = 2mm / 1024 = 1.95µm/LSB
Exampndi 2:
Pogwiritsa ntchito makonzedwe omwewo pa AS5510, mzere wozungulira wa maginito pamtunda womwewo wa ± 1mm tsopano ndi ± 20mT m'malo mwa ± 25mT chifukwa cha airgap yapamwamba kapena maginito ofooka. Zikatero kuthetsa kwa kusamutsidwa vs. mtengo wotulutsa ndi wotsika. Max. Kuyenda Distance TDmax = ±1mm (Xmax = 1mm): Kumverera kosasinthika = ±25mT (Register 0Bh ← 01h): zosasinthika
Bmax = 20mT
→ X = -1mm (= -Xmax)
Munda(mT) = -20mT OUTPUT = 102
→ X = 0mm Munda(mT) = 0mT OUTPUT = 511
→ X = +1mm (= +Xmax)
Munda(mT) = +20mT OUTPUT = 920;
Kutulutsa kwamphamvu kopitilira ±1mm: DELTA = 920 - 102 = 818 LSB
Resolution = TDmax / DELTA = 2mm / 818 = 2.44µm/LSB
Kuti musunge kusamvana kwabwino kwa dongosololi, tikulimbikitsidwa kuti tisinthe kukhudzika komwe kuli pafupi kwambiri ndi Bmax ya maginito, ndi Bmax <Sensitivity kupewa kuchuluka kwa mtengo wotuluka.
Ngati chogwirizira maginito chikugwiritsidwa ntchito, chimayenera kupangidwa ndi zinthu zopanda ferromagnetic kuti chisunge kulimba kwa maginito ndi mzere wambiri. Zida monga mkuwa, mkuwa, aluminiyumu, zitsulo zosapanga dzimbiri ndizo zosankha zabwino kwambiri zopangira gawoli.
Zogwirizana ndi AS5510-AB
Mawaya awiri (I²C) okha ndi omwe amafunikira kuti mulumikizane ndi wolandila MCU. Zotsutsa-zokoka zimafunika pa SCL ndi SDA mzere. Mtengo umatengera kutalika kwa mawaya, komanso kuchuluka kwa akapolo pamzere womwewo wa I²C.
Mphamvu yoperekera pakati pa 2.7V ~ 3.6V imalumikizidwa ndi bolodi la adaputala ndi zopinga zokoka.
Adapterboard yachiwiri ya AS5510 (yosankha) imatha kulumikizidwa pamzere womwewo. Zikatero, adilesi ya I²C iyenera kusinthidwa potseka JP1 ndi waya.
Mapulogalamu example
Mukayatsa makinawo, kuchedwa kwa> 1.5ms kuyenera kuchitika I²C yoyamba isanachitike
Werengani/Lembani lamulo ndi AS5510.
The initialization pambuyo mphamvu mmwamba ndi optional. Zimapangidwa ndi:
- Sensitivity kasinthidwe (Register 0Bh)
- Magnet polarity (Register 02h bit 1)
- Pang'onopang'ono kapena Mwachangu (Lembetsani 02h bit 3)
- Power Down mode (Register 02h bit 0)
Kuwerenga mtengo wa maginito ndikolunjika patsogolo. Khodi yotsatirayi imawerengera mphamvu ya maginito ya 10-bit, ndikusintha kukhala mphamvu ya maginito mu mT (millitesla).
ExampLe: Kumverera kusinthidwa kukhala + -50mT osiyanasiyana (97.66mT/LSB); polarity = 0; makonda okhazikika:
- D9..0 mtengo = 0 imatanthauza -50mT pa sensa ya holo.
- D9..0 mtengo = 511 amatanthauza 0mT pa sensa ya holo (palibe maginito, kapena maginito).
- D9..0 mtengo = 1023 amatanthauza +50mT pa sensa ya holo.
