DIGILENT PmodCMPS Input Pmods Sensors Ewner's Manual
Zathaview
The Digilent PmodCMPS imakhala ndi zodziwika bwino Honeywell HMC5883L Kampasi ya digito ya 3-axis ndipo imatha kuwonjezera kuwerengera kwa mutu wa kampasi ku bolodi iliyonse ya Digilent yokhala ndi mawonekedwe a I²C.
Zithunzi za PmodCMPS.
Zina mwazo ndi:
- Kampasi ya digito ya 3-axis
- 2 milli-gauss Field Resolution mu ± 8 gauss minda
- 160 Hz pazipita zotulutsa deta
- Zodzikongoletsera zokoka za SCL ndi zikhomo za SDA
- Kukula kwa PCB yaying'ono pamapangidwe osinthika 0.8" × 0.8" (2.0 cm × 2.0 cm)
- 2 × 4-pini cholumikizira chokhala ndi mawonekedwe a I2C
- Amatsatira Kufotokozera kwa Digilent Pmod Interface
- Library ndi exampkodi ikupezeka mu malo othandizira
Kufotokozera Kwantchito
PmodCMPS imagwiritsa ntchito ukadaulo wa Honeywell's HMC5883L ndiukadaulo wa Anisotropic Magnetoresistive (AMR). M'Chingerezi chomveka bwino, izi zikutanthauza kuti masensa atatu (imodzi pa njira iliyonse yogwirizanitsa) ali ndi zosokoneza pang'ono kuti apeze deta yolondola kuchokera ku Pmod.
Kulumikizana ndi Pmod
Pmod CMPS imalumikizana ndi board board kudzera pa protocol ya I²C. Jumpers JP1 ndi JP2 amapereka zotsutsa zokoka za 2.2kΩ kuti zigwiritse ntchito pa mizere ya Serial Data ndi Serial Clock. Adilesi ya 7-bit ya chip-board iyi ndi 0x1E, kupanga adilesi ya 8-bit ya lamulo lowerengera 0x3D ndi 0x3C kuti mulembe lamulo.
Mwachikhazikitso, PmodCMPS imayambira mu Single Measurement mode kuti kampasi itenge muyeso umodzi, ikhazikitse pini ya Data Ready pamwamba, ndiyeno imadziyika yokha mu Idle Mode. Ndili mu Idle Mode, magwero akuluakulu ogwiritsira ntchito mphamvu ndi (zosadabwitsa) olemala, monga ADC yamkati yomwe imasonkhanitsa vol.tagndi miyeso. Komabe, mutha kupezabe zolembetsa zonse ndi mtengo wawo waposachedwa kwambiri kudzera pa basi ya I²C. Kuti musinthe PmodCMPS kuchokera kumayendedwe osagwira ntchito kubwereranso muyeso Imodzi kapena Njira Yoyezera Yopitilira, wogwiritsa ntchito ayenera kulembera ku Registry ya Mode (0x02).
Powerenga deta kuchokera ku Pmod CMPS, zolembera zonse zisanu ndi chimodzi, zogwirizana ndi ma byte apamwamba ndi apansi a njira iliyonse ya Cartesian coordinate, iyenera kuwerengedwa. Popeza cholozera cha adilesi yamkati chimangowonjezera kaundula ikawerengedwa bwino, ndizotheka kuwerenga kuchokera m'marejista onse asanu ndi limodzi ndi lamulo limodzi. Exampmomwe izi zingawonekere apa apa:

The Pmod Mtengo wa CMPS imaperekanso njira yodziyesera yokha kuti ithandizire kuwongolera deta iliyonse yomwe ikulandiridwa kuchokera mugawoli.
Mphamvu iliyonse yakunja yogwiritsidwa ntchito ku PmodCMPS iyenera kukhala mkati mwa 2.16V ndi 3.6V; Chifukwa chake, mukamagwiritsa ntchito mitu ya Pmod pama board a Digilent system, voltagayenera kukhala pa 3.3V.
Miyeso Yathupi
Mapini pamutu wa pini amatalikirana ndi 100 mil. PCB ndi mainchesi 0.8 m'mbali mwake molingana ndi zikhomo pamutu wa pini ndi mainchesi 0.8 m'mbali mwake molingana ndi mutu wa pini.
