Overview
Iyo PmodACL2 ndeye 3-axis MEMS accelerometer inofambiswa neAnalog Devices ADXL362. Nekutaurirana nechip kuburikidza neSPI protocol, vashandisi vanogona kugashira anosvika gumi nemaviri mabheti ekugadzirisa kune yega axis yekumhanyisa. Pamusoro pezvo, modhi iyi inopa yekunze inokonzeresa inonzwa kuburikidza nekuona kamwe kana kaviri-tepi pamwe nekuchengetedza magetsi maficha kuburikidza nekusaita basa kwekutarisa.

Product Features

• 3-axis MEMS accelerometer
• Kusvikira ku12 bits ekugadzirisa pane axis
• Mushandisi-selectable resolution
• Chiitiko/kusaita chekutarisa
• Kuderera kwezvino kushandiswa

Mirayiridzo Yekushandiswa Kwechigadzirwa

1. Batanidza iyo PmodACL2 kune yako microcontroller kana bhodhi rekuvandudza uchishandisa SPI protocol.
2. Simba paPmodACL2 uye yako microcontroller/development board.
3. Kuti uverenge data yekumhanyisa, tumira mirairo yakakodzera kuPmodACL2 kuburikidza neSPI.
4. Iyo PmodACL2 inopa anosvika gumi nemaviri mabheti ekugadzirisa kune yega axis yekumhanyisa. Shandisa mushandisi-selectable resolution chimiro kugadzirisa yaunoda kugadzirisa.
5. Kuti uone zvinokonzeresa zvekunze, gonesa iyo imwechete kana kaviri-tap yekuona chimiro paPmodACL2.
6. Kuti uchengetedze simba, shandisa iyo kusaita yekutarisa chimiro chePmodACL2.
7. Tarisa kuPmodACL2 Reference Manual kuti uwane ruzivo rwakadzama pamusoro pemirairo yeSPI uye sarudzo dzekugadzirisa.

Tsanangudzo Yekushanda
Iyo PmodACL2 inoshandisa Analog Devices ADXL362 kupa MEMS kukurumidza data kubhodhi system. Nekudzika kwayo 512-sample FIFO buffer, vashandisi vanokwanisa view tambo refu yezviitiko isati yakonzeresa kukanganisa kana kungokwanisa kuve neiyo system board yekuwana yekuwedzera data kana mushandisi aiwana iri nyore.

Kudyidzana nePmod

Iyo PmodACL2 inotaurirana nebhodhi rekugamuchira kuburikidza neSPI protocol. Kuti uverenge kubva pane-bhodhi data marejista,
iyo Chip Sarudza mutsara inofanira kutanga yadhonzwa pasi uye yozotumira command byte kuverenga kubva kune data register (0x0B).
Iyo inodiwa kero byte inofanirwa kutumirwa inotevera, uyezve yaunoda byte inogamuchirwa neMSB kutanga painodonha wachi. Nekuti iyo kero pointer auto-increments kune inotevera kero byte, zvinokwanisika kuverenga akawanda byte zvakateerana nekuenderera mberi nekupuruzira iyo Serial Clock mutsara. An exampseti yemirairo yekuverenga kubva kune yaxis rejista inopiwa pazasi:

Kuti uverenge kubva kuFIFO buffer, command byte yekunyorera kurejista yedata (0x0A) inofanira kutanga yatumirwa kuitira kuti tigadzirise iyo FIFO Control rejista (kero 0x28) kuratidza kuti tinoda iyo FIFO buffer kuchengetedza data. Mushure mekunge iyo ADXL362 yakagadziridzwa kuti ishandise iyo FIFO buffer, yekuraira byte kuverenga kubva kuFIFO buffer (0x0D) inofanira kutanga yatumirwa, yozoteverwa nemapeya emabhayiti edata ane axis iri kuyerwa pamwe neiyo data yekumhanyisa.

Iyo PmodACL2 zvakare ine maviri programmable kukanganisa mapini aripo ekushandisa. Ose mapini aya anogona kusetwa kuti akonzere kukanganisa pane akawanda akasiyana zvinokonzeresa zvinosanganisira chiitiko/kusaita (kubatsira kudzikisa system simba), kana iyo FIFO buffer yazadzwa kusvika padanho rinodiwa, kana data yagadzirira kutorwa, uye zvimwe zvinokonzeresa.
Chero simba rekunze rinoshandiswa kuPmodACL2 rinofanira kunge riri mukati me1.6V uye 3.5V. Nekuda kweizvozvo, neDigilent system mabhodhi, iyi Pmod inofanirwa kumhanyiswa kubva panjanji ye3.3V.

Muviri Dimensions
Mapini ari pamusoro wepini akapatsanurwa 100 mil kure. Iyo PCB yakareba 0.95 inches pamativi anoenderana nemapini ari pamusoro wepini uye 0.8 inches kureba pamativi perpendicular kumusoro wepini.
