Ukuze ufunde amanani ngaphandle, sebenzisa okulandelayo ngaphansi kwemvelo ye-python3: SMBus.read_word_data(0x51, 0x28) SMBus.read_word_data(0x51, 0x2a) SMBus.read_word_data(0x51, 0x2c) SMBus.read_word_data(0x51e)
Amanani okubuya nawo angamagama angama-2-byte. Njengoba imiyalo iphatha igama le-2-byte ngokuqondile, abasebenzisi akudingeki bakhathazeke mayelana ne-indian byte oda lapha.

Bhala i-RDO (0x30~0x33)

Ukuqala inqubo yokuxoxisana yesicelo se-PDO, idatha ye-4-byte ibhalelwa irejista ye-RDO (Request Data Object) nge-oda elincane le-byte. Njengoba example, ukucela i-PDO3 nge-15V kanye ne-3A, 0x3004B12C izobhalelwa kurejista ye-RDO. Sebenzisa okulandelayo ngaphansi kwemvelo ye-python3:

SMBus.write_i2c_block_data(0x51, 0x30, [0x2c, 0xb1, 0x04, 0x30])
Sicela ubheke Ithebula 9 kanye neThebula 10 le-AP33772 Sink Controller EVB Umhlahlandlela Womsebenzisi ukuze uthole imininingwane enemininingwane yokuqukethwe kwe-RDO.
Umsebenzisi angakhipha ukusetha kabusha kanzima ngokubhala irejista ye-RDO enedatha ye-all-zero:
SMBus.write_i2c_block_data(0x51, 0x30, [0x00, 0x00, 0x00, 0x00])
I-AP33772 Sink Controller izosethwa kabusha ukuze ibe kusimo sayo sokuqala futhi okukhiphayo kuzovalwa.

ISAZISO ESIBALULEKILE

AMA-DIOD AHLANGANISIWE AWENZI ISIQINISEKISO SANOMA YILUPHI UHLOBO, OKUSHIWO NOMA OKUSHIWOYO, NGOKUPHATHELENE NALO MBHALO, KUHLANGANISA, KODWA AKUkhawulelwe, IZIQINISEKISO EZISHIWO ZOKUTHENGISWA NOKULUNGELA INDLELA ETHILE (FUNYE NOKUNGABIZWA KWAYO).
I-Diodes Incorporated nezinkampani ezingaphansi kwayo inelungelo lokwenza izinguquko, izithuthukisi, ukuthuthukiswa, ukulungisa, noma ezinye izinguquko ngaphandle kwesaziso esengeziwe kulo mbhalo nanoma yimuphi umkhiqizo ochazwe lapha. I-Diodes Incorporated ayithathi noma yisiphi isikweletu esivela ngenxa yesicelo noma ukusetshenziswa kwalo mbhalo nanoma yimuphi umkhiqizo ochazwe lapha; futhi i-Diodes Incorporated ayidluliseli noma yiliphi ilayisense ngaphansi kwelungelo layo lobunikazi noma amalungelo ophawu lokuhweba, noma amalungelo abanye. Noma yiliphi iKhasimende noma umsebenzisi walo mbhalo noma imikhiqizo echazwe lapha kulezo zinhlelo zokusebenza uzothatha zonke izingozi zokusebenzisa lokho futhi uzovuma ukubamba i-Diodes Incorporated kanye nazo zonke izinkampani imikhiqizo yazo emelwe ku-Diodes Incorporated. webindawo, ayinangozi kuwo wonke umonakalo.
I-Diodes Incorporated ayinikezi noma yamukele noma isiphi isikweletu maqondana nanoma yimiphi imikhiqizo ethengwe ngamashaneli okuthengisa angagunyaziwe.
Uma Amakhasimende athenga noma asebenzise imikhiqizo ye-Diodes Incorporated kunoma isiphi isicelo esingahlosiwe noma esingagunyaziwe, Amakhasimende azovikela futhi abambe ama-Diodes

Okuhlanganisiwe nabameleli bayo bebengenangozi kuzo zonke izimangalo, amademeshe, izindleko, nezimali zommeli ezivela, ngokuqondile noma ngokungaqondile, noma isiphi isimangalo sokulimala komuntu siqu noma ukufa okuhlobene nesicelo esinjalo esingahlosiwe noma esingagunyaziwe.
Imikhiqizo echazwe lapha ingakhandwa yi-United States eyodwa noma ngaphezulu, amalungelo obunikazi amazwe ngamazwe noma angaphandle alindile. Amagama omkhiqizo kanye nezimpawu eziphawulwe lapha zingase futhi zifakwe yi-United States eyodwa noma ngaphezulu, izimpawu zokuthengisa zamazwe ngamazwe noma zangaphandle.
Lo mbhalo ubhalwe ngesiNgisi kodwa ungahunyushelwa ezilimini eziningi ukuze usetshenziswe. Inguqulo yesiNgisi kuphela yale dokhumenti eyifomethi yokugcina nenqumayo ekhishwe yi-Diodes Incorporated.

UKUSEKELWA KWEMPILO

Imikhiqizo ye-Diodes Incorporated ayigunyaziwe ngokukhethekile ukuthi isetshenziswe njengezingxenye ezibalulekile kumadivayisi noma amasistimu okusekela ukuphila ngaphandle kwemvume ebhaliwe evela kuMphathi Omkhulu we-Diodes Incorporated. Njengoba kusetshenziswe lapha:
A. Amadivayisi noma amasistimu asekela impilo angamadivayisi noma amasistimu:

zihloselwe ukugxilisa emzimbeni, noma
ukusekela noma ukusekela ukuphila kanye nokwehluleka kwakho ukusebenza lapho kusetshenziswe kahle ngokuhambisana nemiyalelo yokusetshenziswa enikezwe kulebula kungalindelwa ngokuphusile ukuthi kubangele ukulimala okukhulu kumsebenzisi.
- B. Ingxenye ebalulekile yinoma iyiphi ingxenye kudivayisi noma uhlelo olusekela ukuphila ukwehluleka ukusebenza okungalindeleka ngokuphusile kubangele ukwehluleka kwedivayisi esekela ukuphila noma kuthinte ukuphepha noma ukusebenza kahle kwayo.
- Amakhasimende amele ukuthi anabo bonke ubungcweti obudingekayo ekuvikelekeni nasekulawuleni amathuluzi noma amasistimu awo okusekela ukuphila, futhi ayavuma futhi ayavuma ukuthi anesibopho sazo zonke izimfuneko ezingokomthetho, zokulawula, neziphathelene nokuphepha eziphathelene nemikhiqizo yawo nanoma yikuphi ukusetshenziswa kwe-Diodes. Imikhiqizo ehlanganisiwe kumathuluzi anjalo abalulekile okuphepha, asekela ukuphila noma amasistimu, ngaphandle kwanoma imaphi amadivaysi- noma ulwazi oluhlobene namasistimu noma usekelo olungase lunikezwe i-Diodes Incorporated.
- Ngaphezu kwalokho, Amakhasimende kufanele akhokhe ngokugcwele i-Diodes Incorporated kanye nabameleli bayo kunoma yimuphi umonakalo ovela ngenxa yokusebenzisa imikhiqizo ye-Diodes Incorporated kumadivayisi anjalo abalulekile okuphepha, asekela ukuphila noma amasistimu.
