Isaziso soMlandu wokuzilandula ngokwasemthethweni
IDATHA YOBUCHWEPHESHE NEENKONZO YEEMVELISO ZERASPBERRY PI (KUQUKA IIDETASHEETS) NJENGOKO ZILUNGISWE NGAMAXESHA NGEXESHA (“IZIBONELELO”) ZINIKEZELWA YI-RASPBERRY PI LTD (“RPL”) “NJENGOKO ZINJALO” KUNYE NAYIPHI NA INKCAZELO OKANYE OKUNGABANDELEKILEYO, UNGAHLANGANISIWE, UNGAHLANGANISIWE. IZIQINISEKISO ZOKURhweba NOKULUNGELA NGENJONGO ETHILE ZIXINWE. NGENXA EYENZAYO EVUNYIWE NGOMTHETHO OSEBENZAYO KUKHO AKUKHO SIGANEKO I-RPL AYIYI KUTHWALAPHA NALUPHI NA INDLELA ETHILE, ENGACHASANGA, ESENZAYO, ESESITHENI, ESIKHETHEKILEYO, OMZEKELO, OKANYE OKUPHUMELELEYO (KUBANDAKANYEKA, KODWA AKUNIKEZELWA INGXELO YOLUNTU; UKUSETYENZISWA, IINKCUKACHA OKANYE IINZUZO OKANYE UKUPHAZAMISEKA KWESHISHINI) NANGONA KUBANGELEKILEYO KUNYE NAKUYAYIPHI NA ITHIYORI YOBUXHOXO, ENOBA KUKWISIVUMELWANO, UXANDUVA OLUQINISEKILEYO, OKANYE UKUBANDAKANYA KUNGAkhathali OKANYE NGENXA ENYE) EVELA NGAYO NAYIPHI NA IINDLELA ZOKUSEBENZA, NGAPHANDLE KWENCEBISO. UMONAKALO OLULO. I-RPL inelungelo lokwenza naluphi na uphuculo, uphuculo, izilungiso okanye naluphi na olunye uhlengahlengiso kwi-RESOURCES okanye naziphi na iimveliso ezichazwe kuzo nangaliphi na ixesha kwaye ngaphandle kwesaziso esongezelelweyo. I-RESOURCES yenzelwe abasebenzisi abanezakhono abanamanqanaba afanelekileyo olwazi loyilo. Abasebenzisi banoxanduva kuphela lokukhetha kunye nokusetyenziswa kwe-RESOURCES kunye naluphi na usetyenziso lweemveliso ezichazwe kuzo. Umsebenzisi uyavuma ukuhlawula kunye nokubamba i-RPL ingenabungozi kuwo onke amatyala, iindleko, umonakalo okanye enye ilahleko evela kusetyenziso lwabo lwe-RESOURCES. I-RPL inika abasebenzisi imvume yokusebenzisa i-RESOURCES kuphela ngokudibana neemveliso zeRaspberry Pi. Konke okunye ukusetyenziswa kwe-RESOURCES akuvumelekanga. Akukho layisenisi inikwa nayiphi na enye i-RPL okanye elinye ilungelo lepropathi enomgangatho ophezulu wokuqonda. IMISEBENZI YOMNGCIPHEKO OMKHULU. Iimveliso zeRaspberry Pi aziyilwanga, zenziwe okanye zenzelwe ukusetyenziswa kwiindawo ezinobungozi ezifuna ukungaphumeleli kokusebenza okukhuselekileyo, njengokusebenza kwezixhobo zenyukliya, ukuhamba ngenqwelomoya okanye iinkqubo zonxibelelwano, ulawulo lwezithuthi zomoya, izixhobo zezixhobo okanye izicelo ezibalulekileyo zokhuseleko (kubandakanywa neenkqubo zokuxhasa ubomi kunye nezinye izixhobo zonyango), apho ukusilela kweemveliso kunokukhokelela ekufeni ngokuthe ngqo, ukwenzakala okanye ukonakala okukhulu ngokwasemzimbeni okanye umngcipheko wokusingqongileyo (“). I-RPL ayibangi ngokungqalileyo nayiphi na iwaranti ecacileyo okanye echaziweyo yokufaneleka kweMisebenzi yoMngcipheko oMkhulu kwaye ayamkeli xanduva lokusebenzisa okanye ukubandakanywa kweemveliso zeRaspberry Pi kwiMisebenzi yoMngcipheko oMkhulu. Iimveliso zeRaspberry Pi zinikezelwa ngokuxhomekeke kwiMigaqo eMiselweyo yeRPL. Ubonelelo lwe-RPL YEZIBONELELO alwandisi okanye luyiguquli ngenye indlela iMigaqo eMigangatho ye-RPL, kuquka kodwa kungaphelelanga kwizithintelo kunye neziqinisekiso ezichazwe kuzo.

Intshayelelo
I-Raspberry Pi 4/5 kunye neRaspberry Pi Compute Module 4 izixhobo zisebenzisa i-Power Management Integrated Circuit (PMIC) ukubonelela ngeevolthi ezahlukeneyo.tagezifunwa ngamacandelo ahlukeneyo kwi-PCB. Bakwalandelelanisa amandla-phezulu ukuqinisekisa ukuba izixhobo ziqalwa ngolandelelwano oluchanekileyo. Ngethuba lokuveliswa kwezi modeli, inani lezixhobo ze-PMIC ezahlukeneyo zisetyenzisiwe. Zonke ii-PMICS zibonelele ngokusebenza okongeziweyo ngaphezulu nangaphezulu kwaleyo yomqulutagUkubonelela:
- Imijelo emibini ye-ADC enokusetyenziswa kwi-CM4.
- Kuhlaziyo lwamva lweRaspberry Pi 4 kunye neRaspberry Pi 400, kunye nayo yonke imifuziselo yeRaspberry Pi 5, ii-ADCs zitsalwa ngeengcingo ukuya kwi-USB-C isinxibelelanisi samandla kwiCC1 kunye neCC2.
- Inzwa ye-on-chip enokusetyenziswa ukujonga ubushushu be-PMIC, ekhoyo kwi-Raspberry Pi 4 kunye ne-5, kunye ne-CM4.
Olu xwebhu luchaza indlela yokufikelela kwezi mpawu kwisoftware.
ISILUMKISO
Akukho siqinisekiso sokuba oku kusebenza kuya kugcinwa kwiinguqulelo zexesha elizayo ze-PMIC, ngoko ke kufuneka kusetyenziswe ngononophelo.
Usenokunqwenela ukubhekisa kula maxwebhu alandelayo:
- IRaspberry Pi CM4 yedatha https://datasheets.raspberrypi.com/cm4/cm4-datasheet.pdf
- I-Raspberry Pi 4 encitshisiweyo ye-schematics: https://datasheets.raspberrypi.com/rpi4/raspberry-pi-4-reduced-schematics.pdf
Eli phepha limhlophe lithatha ukuba iRaspberry Pi iqhuba iRaspberry Pi OS, kwaye ihlaziyiwe ngokupheleleyo kunye ne-firmware yamva nje kunye neekernel.
Ukusebenzisa iimpawu
Ekuqaleni ezi mpawu bezifumaneka kuphela ngokufunda ngokuthe ngqo iirejista kwi-PMIC ngokwayo. Nangona kunjalo, iidilesi zerejista ziyahluka ngokuxhomekeke kwi-PMIC esetyenzisiweyo (kwaye ke ngoko kuhlaziyo lwebhodi), ngoko ke iRaspberry Pi Ltd ibonelele ngohlaziyo lwe-agnostic yokufumana olu lwazi. Oku kubandakanya ukusebenzisa isixhobo somgca womyalelo vcgencmd, eyinkqubo evumela usetyenziso lwesithuba somsebenzisi ukufikelela kulwazi olugcinwe okanye olufunyenwe kwisixhobo se-firmware seRaspberry Pi Ltd.
Imiyalelo ekhoyo ye-vcgencmd yile ilandelayo:
| Umyalelo | Inkcazo |
| vcgencmd measure_volts usb_pd | Ilinganisa umthamotage kwiphini eliphawulwe usb_pd (Jonga iCM4 IO schematic). CM4 kuphela. |
| vcgencmd measure_volts ain1 | Ilinganisa umthamotage kwiphini eliphawulwe ain1 (Jonga i-CM 4 IO schematic). CM4 kuphela. |
| vcgencmd measure_temp pmic | Ilinganisa ubushushu be-PMIC bafa. I-CM4 kunye neRaspberry Pi 4 kunye ne-5. |
Yonke le miyalelo iqhutywa ukusuka kumgca womyalelo weLinux.
Ukusebenzisa iimpawu ezivela kwikhowudi yeprogram
Kuyenzeka ukusebenzisa le miyalelo ye vcgencmd ngokwenkqubo ukuba ufuna ulwazi ngaphakathi kwesicelo. Kuzo zombini i-Python kunye ne-C, ifowuni ye-OS ingasetyenziselwa ukuqhuba umyalelo kunye nokubuyisela umphumo njengomtya. Nazi ezinye example Python ikhowudi enokusetyenziswa ukubiza vcgencmd umyalelo:
Le khowudi isebenzisa imodyuli ye-Python subprocess ukubiza umyalelo we-vcgencmd kwaye udlule kumyalelo we- measure_temp ojolise kwi-pmic, oya kulinganisa ubushushu be-PMIC bafe. Isiphumo somyalelo siya kuprintwa kwi-console.
Nantsi i-ex efanayoampkwi C:
Ikhowudi ye-C isebenzisa i-popen (kunokuba i-system (), nayo enokuba lukhetho), kwaye mhlawumbi i-verbose kancinane kunokuba ifuneka kuba inokusingatha iziphumo zelayini ezininzi ukusuka kumnxeba, ngelixa i-vcgencmd ibuyisela kuphela umgca omnye wokubhaliweyo.
PHAWULA
Ezi zicatshulwa zekhowudi zinikezelwa kuphela njenge-exampLes, kwaye unokufuna ukuziguqula ngokuxhomekeke kwiimfuno zakho ezithile. UmzekeloampLe, ungafuna ukwahlula imveliso yomyalelo we vcgencmd ukukhupha ixabiso lobushushu bokusetyenziswa mva.
Imibuzo ebuzwa qho
