Hōʻike ka Digilent PmodCMPS i ka mea kaulana Honeywell HMC5883L 3-axis kikohoʻe panana a hiki ke hoʻohui i nā helu helu poʻomanaʻo i kēlā me kēia papa hoʻokipa Digilent me kahi interface I²C.
ʻO ka PmodCMPS.
Aia nā hiʻohiʻona:
- 3-axis kikohoʻe panana
- 2 milli-gauss Field Resolution ma ± 8 gauss mahina
- 160 Hz kiʻekiʻe loa kaʻikepili puka puka
- Nā pale huki huki koho no nā pine SCL a me SDA
- ʻO ka nui PCB liʻiliʻi no nā hoʻolālā maʻalahi 0.8" × 0.8" (2.0 cm × 2.0 cm)
- 2×4-pin konohiki me I2C interface
- Hahai ʻO Digilent Pmod Interface Specification
- Hale waihona puke a me example code loaʻa ma kumu waiwai
Ka wehewehe hana
Hoʻohana ka PmodCMPS i ka HMC5883L o Honeywell me ka ʻenehana Anisotropic Magnetoresistive (AMR). Ma ka ʻōlelo Pelekania maʻalahi, ʻo ia ke ʻano o nā mea ʻike ʻekolu (hoʻokahi no kēlā me kēia kuhikuhi hoʻonohonoho) ʻaʻole liʻiliʻi loa i kekahi i kekahi i hiki ke kiʻi ʻia ka ʻikepili pololei mai ka Pmod.
Hoʻopili me ka Pmod
Kūkākūkā ka Pmod CMPS me ka papa hoʻokipa ma o ka protocol I²C. Hāʻawi nā Jumpers JP1 a me JP2 i nā mea huki huki 2.2kΩ koho e hoʻohana no nā laina Serial Data a me Serial Clock. ʻO ka helu helu 7-bit no kēia puʻupuʻu ma ka papa he 0x1E, e hana ana i ka helu 8-bit no kahi kauoha heluhelu 0x3D a me 0x3C no kahi kauoha kākau.
ʻO ka mea paʻamau, hoʻomaka ka PmodCMPS ma ke ʻano Ana Hoʻokahi i hiki i ke panana ke ana hoʻokahi, hoʻonoho i ka pine Ready Data kiʻekiʻe, a laila hoʻokomo iā ia iho i ka Idle Mode. ʻOiai i ka Idle Mode, ʻaʻole i kāhāhā nā kumu nui o ka hoʻohana ʻana i ka mana, e like me ka ADC kūloko e hōʻiliʻili i ka vol.tage ana ana. Eia nō naʻe, hiki iā ʻoe ke komo i nā papa inoa a pau me kā lākou waiwai ʻikepili hou loa ma o ka pahi I²C. No ka hoʻololi ʻana i ka PmodCMPS mai ke ʻano idle e hoʻi i loko o ke Ana Hoʻokahi a i ʻole ke Ana Hoʻomau, pono ka mea hoʻohana e kākau i ka Mode Register (0x02).
I ka heluhelu ʻana i ka ʻikepili mai ka Pmod CMPS, pono e heluhelu ʻia nā papa inoa ʻeono a pau, e pili ana i nā bytes luna a me lalo o kēlā me kēia kuhikuhi Cartesian coordinate. Ma muli o ka hoʻonui ʻana o ka helu helu helu helu kūloko ma hope o ka heluhelu ʻana i kahi papa inoa, hiki ke heluhelu ʻia mai nā papa inoa ʻeono me hoʻokahi kauoha. He exampʻO ke ʻano o ke ʻano o kēia mea i hāʻawi ʻia ma lalo nei:
Papa 1. Ke kauoha a me ka helu ʻana i nā bytes.
| Kauoha byte | Byte helu wahi | ||||||||||||||||
| 0 | 0 | 1 | 1 | 1 | 1 | 0 | 1 | (ACK) | 0 | 0 | 0 | 0 | 0 | 0 | 1 | 1 | (ACK) |

Nānā: Kū ʻo SX no kahi hoʻonui hōʻailona o ka bit sign (sb).
Papa wehewehe Pinout
Papa 1. Mea Hoʻohui J1: Nā wehewehe pine e like me ka lepili ma ka Pmod.
| Poʻomanaʻo J1 | ||
| Nā pine | hōʻailona | wehewehe |
| 1 & 5 | SCL | Uaki Serial |
| 2 & 6 | SDA | ʻIkepili Serial |
| 3 & 7 | GND | Ka Papa Mana Mana |
| 4 & 8 | VCC | Mea Mana Mana (3.3V) |
| Poʻomanaʻo J2 | ||
| Pin | hōʻailona | wehewehe |
| 1 | MALUHIA | Mākaukau ʻIkepili |
| 2 | GND | Ka Papa Mana Mana |
| ʻO Jumper JP1 | ||
| Mokuʻāina Hoʻouka | Hoʻohana ka laina SDA i kahi pale huki huki 2.2kΩ | |
| ʻO Jumper JP2 | ||
| Mokuʻāina Hoʻouka | Hoʻohana ka laina SCL i kahi pale huki huki 2.2kΩ | |
ʻO ka Pmod CMPS hāʻawi pū i kahi ʻano hoʻāʻo ponoʻī e kōkua i ka calibrate i nā ʻikepili i loaʻa mai ka module.
Pono nā mana waho i hoʻohana ʻia i ka PmodCMPS i loko o 2.16V a me 3.6V; no laila, i ka hoʻohana ʻana i nā poʻomanaʻo Pmod ma nā papa ʻōnaehana Digilent, ʻo ka lako voltage pono ma 3.3V.
Ana Kino
Hoʻokaʻawale ʻia nā pine ma ke poʻo pine i 100 mil kaawale. He 0.8 iniha ka lōʻihi o ka PCB ma nā ʻaoʻao e like me nā pine ma ke poʻo pine a he 0.8 ʻīniha ka lōʻihi ma nā ʻaoʻao e kū pono ana i ke poʻo pine.
Kuleana kope Digilent, Inc.
ʻO nā huahana ʻē aʻe a me nā inoa ʻoihana i ʻōlelo ʻia he mau hōʻailona paha o ko lākou mau mea nona.
