Ua umaview
O le Digilent PmodCMPS faʻaalia le lauiloa Honeywell HMC5883L tapasa numera 3-axis ma e mafai ona fa'aopoopo tusi fa'aulutala tapasa i so'o se Digilent host board e iai le I²C interface.
Le PmodCMPS.
O mea e aofia ai:
- 3-axis numera tapasa
- 2 mili-gauss Field Resolution i ±8 gauss fanua
- 160 Hz le maualuga o fa'amaumauga o fa'amaumauga
- Fa'atosina toso i luga mo pine SCL ma SDA
- Laititi PCB mo mamanu fetuutuunai 0.8" × 0.8" (2.0 cm × 2.0 cm)
- 2x4-pine feso'ota'iga ma le I2C fa'aoga
- Mulimuli Digilent Pmod Interface Fa'amatalaga
- Faletusi ma example code avanoa i totonu nofoaga autu o punaoa
Fa'amatalaga Fa'atino
E fa'aogaina e le PmodCMPS le HMC5883L a Honeywell fa'atasi ai ma le tekonolosi Anisotropic Magnetoresistive (AMR). I le Igilisi manino, o lona uiga o masini e tolu (tasi mo taʻiala faʻatasi taʻitasi) e itiiti lava le faʻalavelaveina o le tasi ma le isi ina ia mafai ai ona maua faʻamatalaga saʻo mai le Pmod.
Fesoʻotaʻiga ma le Pmod
O le Pmod CMPS e fesoʻotaʻi ma le komiti talimalo e ala i le I²C protocol. Jumpers JP1 ma le JP2 e tu'uina atu le 2.2kΩ fa'atosina toso i luga e fa'aoga mo le Fa'amaumauga Fa'asologa ma laina Fa'asologa Fa'asologa. O le tuatusi 7-bit mo lenei va'a i luga o le laupapa o le 0x1E, faia le tuatusi 8-bit mo se fa'atonuga faitau 0x3D ma le 0x3C mo se fa'atonuga tusitusi.
Ona o le faaletonu, o le PmodCMPS e amata i le tulaga o le Fuafuaga Tasi ina ia faia e le tapasa se fua e tasi, seti maualuga le pine o le Data Ready, ona tuu lea o ia lava i le Idle Mode. A'o i le Idle Mode, o fa'apogai tetele o le fa'aaogaina o le eletise e (e le o se mea e ofo ai) fa'aletonu, e pei o le ADC totonu lea e aoina le vol.tagu fua. Ae ui i lea, e mafai lava ona e mauaina uma resitara ma latou fa'amaumauga aupito lata mai e ala ile pasi I²C. Ina ia suia le PmodCMPS mai le idle mode i tua i le Fuafuaina Tasi poʻo le Fua Faʻaauau, e tatau i le tagata faʻaoga ona tusi i le Faʻailoga Faʻamau (0x02).
Pe a faitau faʻamatalaga mai le Pmod CMPS, e tatau ona faitau uma faʻamaumauga e ono, e fetaui ma le pito i luga ma lalo ifo o taʻiala taʻitasi Cartesian. Talu ai e otometi lava ona fa'atuputeleina le fa'ailoga o le tuatusi fa'alotoifale pe a mae'a ona faitau lelei le tusi resitala, e mafai ona faitau mai tusi resitala uma e ono ma se fa'atonuga e tasi. O se examppe faʻapefea ona foliga mai o loʻo tuʻuina atu i lalo:

| Fa'aoso JP2 | ||
| Atunuu uta | Ole laina ole SCL ole fa'aogaina ole 2.2kΩ toso i luga tete'e | |
O le Pmod CMPS e ofoina atu foi se faiga su'ega a le tagata lava ia e fesoasoani i le fa'avasegaina o so'o se fa'amaumauga o lo'o maua mai le module.
So'o se malosiaga mai fafo e fa'aoga i le PmodCMPS e tatau ona i totonu ole 2.16V ma le 3.6V; o le mea lea, pe a faʻaaogaina ulutala Pmod i luga ole Digilent system boards, o le sapalai voltage tatau ona i le 3.3V.
Fua Fa'aletino
O pine o le pine ulu o lo'o va i le 100 maila le va. O le PCB e 0.8 inisi le umi i itu e tutusa ma pine i luga o le pine ulu ma 0.8 inisi le umi i itu faʻasaga i le pine ulu.
