Overview
Iyo Digilent PmodCMPS inoratidzira yakakurumbira Honeywell HMC5883L 3-axis digitaalinen kambasi uye inogona kuwedzera kambasi musoro kuverenga kune chero Digilent host board ine I²C interface.
Iyo PmodCMPS.
Zvimiro zvinosanganisira:
- 3-axis digital kambasi
- 2 milli-gauss Munda Resolution mu ±8 gauss minda
- 160 Hz yakanyanya kuburitsa data chiyero
- Optional kudhonza-up resistors ye SCL uye SDA pini
- Diki PCB saizi yemagadzirirwo anochinjika 0.8" × 0.8" (2.0 cm × 2.0 cm)
- 2 × 4-pini yekubatanidza ine I2C interface
- Inotevera Digilent Pmod Interface Kutsanangurwa
- Library uye example code inowanikwa mukati resource centre
Tsanangudzo Yekushanda
Iyo PmodCMPS inoshandisa Honeywell's HMC5883L ine Anisotropic Magnetoresistive (AMR) tekinoroji. MuchiRungu chakajeka, izvi zvinoreva kuti masensa matatu (imwe yeimwe neimwe nzira yekurongeka) ane zvishoma zvakanyanya kukanganisa kune mumwe nemumwe kuitira kuti data chaiyo itore kubva kuPmod.
Kudyidzana nePmod
Iyo Pmod CMPS inotaurirana neiyo host board kuburikidza neI²C protocol. Jumpers JP1 uye JP2 inopa sarudzo 2.2kΩ kudhonza-kumusoro zvidziviriro zvekushandisa kune Serial Data uye Serial Clock mitsetse. Iyo 7-bit kero yeiyi pa-board chip ndeye 0x1E, ichigadzira iyo 8-bit kero yekuverenga kuraira 0x3D uye 0x3C yekuraira kunyora.
Nekumisikidza, iyo PmodCMPS inotanga muIngle Measurement modhi kuitira kuti kambasi itore chiyero chimwe chete, inoseta iyo Data Ready pini kumusoro, uye yozozviisa muIdle Mode. Ndichiri muIdle Mode, masosi makuru ekushandisa simba (hazvishamise) akaremara, senge iyo yemukati ADC inounganidza vol.tage zviyero. Nekudaro, iwe uchiri kukwanisa kuwana ese marejista neavo azvino data kukosha kuburikidza neI²C bhazi. Kuti uchinje iyo PmodCMPS kubva kune isina basa modhi kudzokera kune Imwe Measurement kana Kuenderera Measurement modhi, mushandisi anofanira kunyorera kuModhi Rejista (0x02).
Paunenge uchiverenga data kubva kuPmod CMPS, ese matanhatu marejista edata, anoenderana nepamusoro uye akadzika mabheti ega ega Cartesian coordination direction, anofanira kuverengwa. Sezvo iyo yemukati rejista kero pointer inongowedzera kuwedzera mushure mekunge rejista yaverengwa zvinobudirira, zvinokwanisika kuverenga kubva kune ese matanhatu marejista nemurairo mumwe chete. An exampkuti izvi zvingaratidzika sei zvinopiwa pasi apa:

The Pmod CMPS inopawo yekuzviedza modhi yekubatsira kugadzirisa chero data riri kugamuchirwa kubva module.
Chero simba rekunze rinoshandiswa kuPmodCMPS rinofanira kunge riri mukati me2.16V uye 3.6V; saka, kana uchishandisa Pmod misoro paDigilent system mabhodhi, iyo yekugovera voltaginofanira kunge iri 3.3V.
Muviri Dimensions
Mapini ari pamusoro wepini akapatsanurwa 100 mil kure. Iyo PCB yakareba 0.8 inches pamativi anoenderana nemapini ari pamusoro wepini uye 0.8 inches kureba pamativi perpendicular kumusoro wepini.
