Kuisa iyo AS5510 Adapter board

Iyo AS5510-AB inogona kumiswa kune iripo mechaniki system nemaburi ayo mana anokwira. A simple 2-poles magineti akaiswa pamusoro kana pasi peIC anogona kushandiswa.
Mufananidzo 4:
AS5510 adapta bhodhi kukwira uye dimension

Iyo yakanyanya kuchinjika kufamba amplitude zvinoenderana nechimiro chemagneti uye saizi uye simba remagineti (magineti zvinhu uye airgap).
Kuti uyere kufamba kwemakanika nemhinduro yemutsara, chimiro chemagneti pamhepo yakagadziriswa chinofanira kunge chakaita paFigure 5:.
Mutsara wehupamhi hwemagineti pakati peMaodzanyemba neMaodzanyemba pole inotaridza hukuru hwekufamba hwemagineti. Hushoma (-Bmax) uye huwandu hwemagineti (+Bmax) hwemagineti emutsetse wemutsara hunofanirwa kunge hwakaderera kana kuenzana neimwe yezvina manzwiro anowanikwa paAS5510 (register 0Bh): Sensitivity = ± 50mT, ± 25mT, ±18.5mT. , ±12.5mT Iyo 10-bit inobuda register D[9..0] OUTPUT = Munda(mT) * (511/Sensitivity) + 511.

Iyi ndiyo kesi yakakodzera: mutsara wegineti i ± 25mT, inokwana ± 25mT senitivity setting yeAS5510. Kugadziriswa kwekudzimisa vs. kukosha kwekubuda kwakanaka.
Max. Kufamba Distance TDmax = ±1mm ( Xmax = 1mm)
Sensitivity = ±25mT (Register 0Bh ← 01h)
Bmax = 25mT
→ X = -1mm (= -Xmax) Munda(mT) = -25mT KUBUDA = 0
→X = 0mm Munda(mT) = 0mT OUTPUT = 511
→ X = +1mm (= +Xmax)
Munda(mT) = +25mT OUTPUT = 1023
Dynamic range ye OUTPUT pamusoro ±1mm: DELTA = 1023 – 0 = 1023 LSB
Resolution = TDmax / DELTA = 2mm / 1024 = 1.95µm/LSB
ExampLe 2:
Uchishandisa marongero mamwe chete paAS5510, mutsara wegineti pamusoro pekufamba kwakafanana kwe ± 1mm ikozvino ± 20mT pachinzvimbo che ± 25mT nekuda kwepamusoro airgap kana kuti isina simba magineti. Muchiitiko ichocho kugadziriswa kwe displacement vs. output value yakaderera. Max. Kufamba Distance TDmax = ±1mm (Xmax = 1mm): Sensitivity isina kuchinjwa = ±25mT (Register 0Bh ← 01h): hazvina kuchinjwa
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;
Dynamic range ye OUTPUT pamusoro ±1mm: DELTA = 920 – 102 = 818 LSB
Resolution = TDmax / DELTA = 2mm / 818 = 2.44µm/LSB
Kuti uchengetedze yakanakisa kugadzirisa kweiyo sisitimu, zvinokurudzirwa kugadzirisa senitivity padyo seBmax yemagneti, neBmax <Sensitivity kudzivirira kuzara kweiyo kukosha kwekubuda.
Kana inobata magineti ikashandiswa, inofanirwa kugadzirwa neisiri-ferromagnetic zvinhu kuitira kuchengetedza iyo yakanyanya magineti simba uye mutsara mukuru. Zvishandiso sendarira, mhangura, aluminium, simbi isina tsvina ndiyo sarudzo dzakanakisa dzekuita chikamu ichi.

Kubatanidza iyo AS5510-AB

Waya mbiri (I²C) chete dzinodiwa pakutaurirana neanotambira MCU. Dhonza-up resistors inodiwa pane ese SCL uye SDA mutsetse. Kukosha kunoenderana nehurefu hwewaya, uye huwandu hwevaranda pane imwechete I²C mutsara.
Iyo magetsi inopa pakati pe2.7V ~ 3.6V yakabatana kune adapta bhodhi uye inodhonza-kumusoro resistors.
Yechipiri AS5510 adapterboard (inosarudza) inogona kubatanidzwa pamutsetse mumwe chete. Kana zvakadaro, iyo I²C kero inofanirwa kuchinjwa nekuvhara JP1 newaya.

Software example

Mushure mekusimbisa sisitimu, kunonoka kwe> 1.5ms kunofanirwa kuitwa pamberi pekutanga I²C
Verenga/Nyora kuraira neAS5510.
Iyo yekutanga mushure memagetsi kumusoro ndeyekusarudza. Zvinosanganisira:
-Sensitivity gadziriso (Register 0Bh)

Magnet polarity (Register 02h bit 1)

Inononoka kana Inokurumidza maitiro (Register 02h bit 3)
Power Down mode (Register 02h bit 0)

Kuverenga iyo magnetic field value yakananga mberi. Iyo inotevera sosi kodhi inoverenga iyo 10 -bit magineti kukosha, uye inoshandura kune iyo magineti simba mumT (millitesla).
Example: Sensitivity configured to + -50mT range (97.66mT/LSB); Polarity = 0; default setting:

D9..0 kukosha = 0 zvinoreva -50mT pane sensor horo.

D9..0 kukosha = 511 zvinoreva 0mT pane sensor horo (hapana magineti, kana pasina magineti).
D9..0 kukosha = 1023 zvinoreva +50mT pane sensor horo.
