Kuphelileview
I-PmodGYRO iyimojula ye-peripheral equkethe inzwa yokunyakaza ye-STMicroelectronics® L3G4200D MEMS. I-L3G4200D ihlinzeka nge-gyroscope yedijithali ene-eksisi emithathu enenzwa yokushisa eyakhelwe ngaphakathi.
Izici zifaka:
- I-SPI ejwayelekile ne-I2C™ interface
- 250/500/2000dps Izixazululo Ezikhethekayo
- Izikhonkwane ezimbili eziphazamisayo ezenziwe ngezifiso
- Amandla phansi kanye nemodi yokulala
- Ukuhlunga isignali okulungisekayo komsebenzisi
Incazelo Esebenzayo
I-PmodGYRO isebenzisa uxhumano olujwayelekile lwamaphini angu-12 futhi ixhumana nge-SPI noma i-I²C, ngokuzenzakalelayo ukuxhumana kwe-I²C. I-resistor yokudonsela phezulu kulayini we-CS igcina idivayisi kumodi ye-I²C ngaphandle kwalapho ulayini we-CS ushayelwa phansi idivayisi eyinhloko.
Isixhumi esibonakalayo
Lapho kuxhunywana nedivayisi umphathi kufanele anikeze ikheli lerejista kanye nefulegi elicacisa ukuthi isenzo esilandelayo esokufunda noma ukubhala. Ukudluliswa kwangempela kwedatha kulandela lo myalo. Ngale ndlela, umsebenzisi angakwazi ukulungisa idivayisi ngokubhalela amarejista athile okulawula ngaphakathi kwedivayisi, noma afundele ukwaziswa okuvela kumarejista ahlukene okufunda kuphela.
Iziphazamiso ezimbili eziqondisa imephu kumaphini atholakala kumsebenzisi kusixhumi esingu-J1 se-PmodGYRO. Ukucushwa kwe-INT1, okukhona kuphinikhodi 7 ye-J1, kungenziwa ngokwezifiso ngokuphelele umsebenzisi. Ukusetshenziswa okuyinhloko kwe-INT1 kusuka ezenzakalweni eziphakeme neziphansi ezimbazweni ezintathu lapho i-gyroscope ikala isivinini se-angular. Ngokuzenzakalelayo, i-INT1 ikhutshaziwe. Ukuphazamiseka kwesibili, i-INT2, isetshenziselwa ngokuyinhloko ukuze idatha isilungile futhi i-FIFO iphazamise futhi amamephu aphine u-8 ku-J1.
Ukuze uthole ulwazi olwengeziwe mayelana namarejista okulawula, ukuqoqwa kwedatha, nezilungiselelo zokuphazamisa ezitholakalayo ukuze zicushwe umsebenzisi, bheka ishidi ledatha le-L3G4200D ku-STMicroelectronics®. webindawo.
Ukuxhumana kwe-SPI
I-interface ye-SPI isebenzisa imigqa yesignali emithathu noma emine yokuxhumana kuye ngokucushwa kwamanje kwedivayisi. Lezi i-Chip Select (CS), i-serial Data In (SDI) noma i-Serial Data (SDA) kumodi ye-SPI enezintambo ezi-3, i-Serial Data Out (SDO), kanye newashi le-serial (SCL). I-PmodGYRO izenzakalela ibe yimodi yokusebenza yezintambo ezi-4. Ukuze usebenzise imodi yezintambo ezi-3, irejista yokulawula kufanele ibhalelwe. Ukuze uthole imininingwane eyengeziwe yokuxhumana kwe-SPI, bheka ishidi ledatha yedivayisi.
I²C Ukuxhumana
Izinga le-I²C lisebenzisa imigqa yesignali emibili, idatha ye-I²C (SDA) kanye newashi lomkhiqizo (SCL). Idivayisi isekela kokubili amawashi ajwayelekile, angu-100 kHz, futhi ayashesha, angu-400 kHz, ama-serial. Ngokuvumelana nephrothokholi ye-I²C, i-L3G4200D inekheli ledivayisi eliqondile elingu-7-bit elisetshenziswa i-serial master ukuxhumana namadivayisi amaningi kubhasi ledatha. Idivayisi isebenzisa ikheli elithi 110100xb, lapho iphinikhodi 3 ku-J1 (SDO/SA0) ichaza ibhithi ebaluleke kakhulu (LSB). Ngokuzenzakalela, i-LSB yekheli kuyilapho ibe ‘1’ ngenxa yesici esiphikisayo sokudonsela phezulu ku-JP1 njengoba kuboniswa uhlaka olutholakala ku-Digilent. webindawo. Nakuba inani elizenzakalelayo lingu-‘1’, ngokumane uxhume iphinikhodi 3 ku-J1 esitimeleni esiphansi umsebenzisi angashintsha i-LSB ibe ngu-‘0’. Le bitana ekhethekayo umsebenzisi inika amandla ama-PmodGYRO amabili ukuthi asetshenziswe ebhasini elifanayo le-I²C. Ishidi ledatha le-L3G4200D liqukethe ulwazi oluthe xaxa lwedivayisi ye-I²C.
