Isaziso Somshwana Wokuzikhipha Emthwalweni Esisemthethweni
IDATHA YOBUCHWEPHESHE NEYETHEMBEKA YEMIKHIQIZO YE-RASPBERRY PI (KUHLANGANISA IMINININGWANE) NJENGOBA ILUNGISWA NGESIKHATHI NGESIKHATHI (“IZINSIZA”) Ihlinzekwa YI-RASPBERRY PI LTD (“RPL”) “NJENGOBA IKHO” KANYE NOMA YILUPHI OKUSHIWO NOMA OKUSHIYELWE, OKUNGEZESIFUNDAZWE, UNGAHLANGANISIWE, UNGAHLANGANISIWE. IZIQINISEKISO ZOKUTHENGISA NOKULUNGA KWENHLOSO ETHILE ZIYISIKHISHIWE. NGESIKHATHI ESESIPHEZULU ESIVUNYWA UMTHETHO OSEBENZAYO AKUKHO MCIMBI ONGAWUKHONJWA I-RPL NGANOMA YILUPHI OKUQONDILE, OKUQONDILE, OKWENZAKALELAYO, OKUKHETHEKILE, OKUYISIBONELO, NOMA OKULANDELAYO (KUHLANGANISA, KODWA AKUNIKEZWE, OKUNYE OKUNIKEZELWA INDLELA YOKUTHENGA; UKUSETSHENZISWA, IDATHA, NOMA IZIMALI; NOMA UKUPHAMEZEKA KWEBHIZINISI) NOMA KUBANGELWE KANYE NAKUNOMA YIMUPHI UMBONO WESIBOPHO, KUNGAKHATHALISEKILE, NGESIBOPHO ESIQINISEKILE, NOMA UKUHLUPHEKA (KUHLANGANISA NEBUDEBEPHO NOMA OKUNYE) KUVELA NGANOMA YILUPHI INDLELA YOKUSETSHENZISWA KOKUSETSHENZISWA KOKUSETSHENZISWA KONKE, OKUNGEZESIFUNDAZWE. LOMONAMANDLA ONJE. I-RPL igodle ilungelo lokwenza noma yiziphi izithuthukisi, intuthuko, izilungiso nanoma yiziphi ezinye izinguquko ku-RESOURCES nanoma yimiphi imikhiqizo echazwe kuyo nganoma yisiphi isikhathi ngaphandle kwesaziso esengeziwe. I-RESOURCES ihloselwe abasebenzisi abanamakhono abanamazinga afanelekile olwazi lokuklama. Abasebenzisi banomthwalo wemfanelo kuphela ekukhetheni kwabo nasekusebenziseni IZINTO EZINGAKUMBI kanye nanoma yikuphi ukusetshenziswa kwemikhiqizo echazwe kuyo. Umsebenzisi uyavuma ukunxephezela futhi abambe i-RPL ingenabungozi kuzo zonke izikweletu, izindleko, umonakalo noma okunye ukulahlekelwa okuvela ngenxa yokusebenzisa kwabo IZINSIZA. I-RPL inikeza abasebenzisi imvume yokusebenzisa i-RESOURCES kuphela ngokuhlangana nemikhiqizo ye-Raspberry Pi. Konke okunye ukusetshenziswa kwe-The RESOURCES akuvunyelwe. Ayikho ilayisensi enikezwa noma iyiphi enye i-RPL noma elinye ilungelo lempahla yengqondo lesithathu. IMISEBENZI YENGOZI EPHEZULU. Imikhiqizo ye-Raspberry Pi ayiklanyelwe, ikhiqizwa noma ihloselwe ukusetshenziswa ezindaweni eziyingozi ezidinga ukwehluleka ukusebenza okuphephile, njengalapho kusebenza khona izakhiwo zenuzi, ukuzulazula kwezindiza noma amasistimu okuxhumana, ukulawulwa kwethrafikhi yomoya, izinhlelo zezikhali noma izinhlelo zokusebenza ezibalulekile zokuphepha (okuhlanganisa izinhlelo ezisekela ukuphila nezinye izisetshenziswa zezokwelapha), lapho ukwehluleka kwemikhiqizo kungaholela ekufeni, ukulimala komuntu siqu noma ukulimala okukhulu ngokomzimba noma kwemvelo ("). I-RPL iyazilahla ngokuqondile noma isiphi isiqinisekiso sokufaneleka esicacile noma esisikiselwayo sokufaneleka Kwemisebenzi Yengcuphe Ephakeme futhi ayamukeli icala lokusetshenziswa noma ukufakwa kwemikhiqizo ye-Raspberry Pi Emisebenzini Enengozi Ephezulu. Imikhiqizo ye-Raspberry Pi inikezwa ngaphansi kweMigomo Ejwayelekile ye-RPL. Ukunikezwa kwe-RPL KWEZINSIZA akukhulisi noma kwenze ngenye indlela Imigomo Ejwayelekile ye-RPL, okuhlanganisa kodwa kungagcini nje ngokuziqhathulula neziqinisekiso ezivezwe kuyo.

Isingeniso
Amadivayisi we-Raspberry Pi 4/5 kanye ne-Raspberry Pi Compute Module 4 asebenzisa i-Power Management Integrated Circuit (PMIC) ukuhlinzeka ngevolumu ehlukahlukene.tagedingwa yizingxenye ezahlukahlukene ze-PCB. Futhi zilandelanisa amandla-ups ukuqinisekisa ukuthi amadivayisi aqalwe ngendlela efanele. Phakathi nesikhathi sokukhiqizwa kwalawa mamodeli, kuye kwasetshenziswa inani lamadivayisi e-PMIC ahlukene. Wonke ama-PMICS ahlinzeke ngokusebenza okwengeziwe ngaphezu kwalokho kwevolumutagUkunikezwa:
- Iziteshi ezimbili ze-ADC ezingasetshenziswa ku-CM4.
- Ezibuyekezweni zakamuva ze-Raspberry Pi 4 ne-Raspberry Pi 400, kanye nawo wonke amamodeli e-Raspberry Pi 5, ama-ADC axhunywe kwintambo yamandla e-USB-C ku-CC1 naku-CC2.
- Inzwa ye-on-chip engasetshenziswa ukuqapha izinga lokushisa le-PMIC, etholakala ku-Raspberry Pi 4 no-5, kanye ne-CM4.
Lo mbhalo uchaza ukuthi ungazifinyelela kanjani lezi zici kusofthiwe.
ISEXWAYISO
Asikho isiqinisekiso sokuthi lokhu kusebenza kuzogcinwa ezinguqulweni ezizayo ze-PMIC, ngakho-ke kufanele kusetshenziswe ngokuqapha.
Ungase ufise ukubheka la madokhumenti alandelayo:
- Idatha ye-Raspberry Pi CM4: https://datasheets.raspberrypi.com/cm4/cm4-datasheet.pdf
- I-Raspberry Pi 4 encishisiwe i-schematics: https://datasheets.raspberrypi.com/rpi4/raspberry-pi-4-reduced-schematics.pdf
Leli phepha elimhlophe lithatha ukuthi i-Raspberry Pi isebenzisa i-Raspberry Pi OS, futhi isesikhathini samanje ne-firmware yakamuva nama-kernels.
Ukusebenzisa izici
Ekuqaleni lezi zici bezitholakala kuphela ngokufunda ngokuqondile amarejista ku-PMIC uqobo. Kodwa-ke, amakheli erejista ayahluka kuye nge-PMIC esetshenzisiwe (ngakho-ke nasesibukezweni sebhodi), ngakho i-Raspberry Pi Ltd inikeze indlela yokubuyekeza-agnostic yokuthola lolu lwazi. Lokhu kuhlanganisa ukusebenzisa ithuluzi lomugqa womyalo i-vcgencmd, okuwuhlelo oluvumela izinhlelo zokusebenza zesikhala somsebenzisi ukuthi zifinyelele ulwazi olugcinwe ngaphakathi noma olufinyelelwe ku-firmware yedivayisi ye-Raspberry Pi Ltd.
Imiyalo etholakalayo ye-vcgencmd imi kanje:
| Umyalo | Incazelo |
| vcgencmd measure_volts usb_pd | Ikala ivolumutage ephinikhodi ebhalwe ukuthi usb_pd (Bona uhlelo lwe-CM4 IO). I-CM4 kuphela. |
| vcgencmd measure_volts ain1 | Ikala ivolumutagephinikhodi ebhalwe ukuthi ain1 (Bona uhlelo lwe-CM 4 IO). I-CM4 kuphela. |
| vcgencmd measure_temp pmic | Ikala izinga lokushisa lokufa kwe-PMIC. I-CM4 ne-Raspberry Pi 4 kanye ne-5. |
Yonke le miyalo iqhutshwa kumugqa womyalo we-Linux.
Ukusebenzisa izici zekhodi yohlelo
Kungenzeka ukusebenzisa le miyalo ye-vcgencmd ngokohlelo uma udinga ulwazi ngaphakathi kohlelo lokusebenza. Kuzo zombili i-Python ne-C, ikholi ye-OS ingasetshenziswa ukuqhuba umyalo futhi ibuyisele umphumela njengeyunithi yezinhlamvu. Nawa ama-example Python code engasetshenziswa ukubiza umyalo we-vcgencmd:
Le khodi isebenzisa imojuli ye-Python subprocess ukuze ishayele umyalo we-vcgencmd futhi idlule umyalo we- measure_temp oqondise ku-pmic, ozokala izinga lokushisa lokufa kwe-PMIC. Ukukhishwa komyalo kuzophrintwa kukhonsoli.
Nali i-ex efanayoample ku C:
Ikhodi C isebenzisa i-popen (kunokuba isistimu(), nayo engaba inketho), futhi cishe ine-verbose kancane kunalokho okudingeka ibe yikho ngoba ingakwazi ukuphatha imiphumela yemigqa eminingi ocingweni, kuyilapho i-vcgencmd ibuyisela umugqa owodwa kuphela wombhalo.
QAPHELA
Lezi zingcaphuno zekhodi zinikezwa kuphela njenge-examples, futhi ungase udinge ukuwashintsha kuye ngezidingo zakho ezithile. Okwesiboneloample, ungase ufune ukuncozulula okukhiphayo komyalo we-vcgencmd ukuze ukhiphe inani lokushisa ukuze usetshenziswe kamuva.
imibuzo ejwayelekile ukubuzwa
- Q: Ngingakwazi ukusebenzisa lezi zici kuwo wonke amamodeli we-Raspberry Pi?
- A: Cha, lezi zici zitholakala ngokukhethekile kumadivayisi we-Raspberry Pi 4, i-Raspberry Pi 5, kanye ne-Compute Module 4.
- Q: Ingabe kuphephile ukuthembela kulezi zici ukuze zisetshenziswe esikhathini esizayo?
- IMP: Asikho isiqinisekiso sokuthi lokhu kusebenza kuzogcinwa ezinguqulweni ze-PMIC ezizayo, ngakho-ke kuxwayiswa uma usebenzisa lezi zici.
