Enye yezinto ezimangalisayo nge-USB-C amandla ayo ejubane eliphezulu. I-pinout ikunikeza amapheya amane ahlukile esivinini esikhulu kanye namapheya ambalwa ahlukile anesivinini esiphansi, okukuvumela ukuthi udlulise amanani amakhulu edatha ngezixhumi ngaphansi kwe-dime. Akuwona wonke amadivayisi asebenzisa lesi sici, futhi akufanele - i-USB-C yakhelwe ukuthi ifinyeleleke kuwo wonke amadivayisi aphathekayo. Kodwa-ke, uma idivayisi yakho idinga isivinini esiphezulu nge-USB-C, uzothola ukuthi i-USB-C ingakunikeza leso sivinini esikhulu nokuthi isebenza kahle kangakanani.
Amandla okuthola isixhumi esibonakalayo esinesivinini esikhulu ku-USB-C ibizwa ngokuthi Imodi Ehlukile, noma Imodi Ehlukile ngamafuphi. Ezinye izindlela ezintathu ongase uhlangane nazo namuhla i-USB3, i-DisplayPort, ne-Thunderbolt, ezinye sezivele zifiphala, njenge-HDMI ne-VirtualLink, kanti ezinye ziyakhuphuka, njenge-USB4. Ezinye izindlela eziningi zidinga ukuxhumana kwedijithali kwe-USB-C kusetshenziswa uhlobo oluthile lwemiyalezo yesixhumanisi se-PD. Nokho, akuwona wonke ama-USB3 alula kakhulu. Ake sibone ukuthi esinye isifanekiso senzani.
Uma uke wabona i-pinout, ubone izikhonkwane zejubane eliphezulu. Namuhla ngifuna ukukukhombisa ukuthi yiziphi izixhumanisi ezitholakala kulawa maphini namuhla. Lolu akulona uhlu oluphelele noma olubanzi – ngeke ngikhulume ngezinto ezifana ne-USB4, ngokwesibonelo, ngokwengxenye ngoba angazi ngokwanele ngayo noma nginolwazi ngayo; kuphephile ukucabanga ukuthi sizothola amadivayisi amaningi ane-USB esikhathini esizayo -C samadivayisi anesivinini esikhulu. Futhi, i-USB-C ivumelana nezimo ngokwanele ukuthi izigebengu zingadalula i-Ethernet noma i-SATA ngendlela ehambisana ne-USB-C - uma kuyilokho okufunayo, mhlawumbe lesi sibuyekezo singakusiza ukuthole.
I-USB3 ilula kakhulu - i-TX embalwa kanye ne-RX embalwa, nakuba izinga lokudlulisa liphakeme kakhulu kune-USB2, liyalawuleka kubaduni. Uma usebenzisa i-PCB enezingqimba eziningi enokulawula kokuthinteleka kwesignali ye-USB3 kanye nokuhlonipha amapheya ahlukile, uxhumano lwakho lwe-USB3 ngokuvamile luzosebenza kahle.
Akukho okuningi okushintshile ku-USB3 phezu kwe-USB-C - uzoba ne-multiplexer yokusingatha ukuzungezisa, kodwa lokho mayelana nakho. Ama-multiplexer e-USB3 agcwele, ngakho-ke uma ungeza imbobo ye-USB-C enikwe amandla i-USB3 ebhodini lakho lomama, mancane amathuba okuba ube nezinkinga. Kukhona futhi i-Dual Channel USB3, esebenzisa iziteshi ezimbili ezifanayo ze-USB3 ukukhulisa umkhawulokudonsa, kodwa abaduni abavamisile ukungena noma bakudingi lokhu, futhi iThunderbolt ivamise ukuvala le ndawo kangcono. Ingabe ufuna ukuguqula idivayisi ye-USB3 ibe idivayisi ye-USB-C? Okudingayo ngempela i-multiplexer. Uma ucabanga ukufaka isixhumi se-MicroUSB 3.0 ebhodini lakho lomama kumadivayisi akho anesivinini esikhulu, ngakho-ke ngikucela ngesizotha kodwa ngokuqinile ukuthi ushintshe umqondo wakho futhi ufake isixhumi se-USB-C ne-VL160 kuso.
Uma uklama idivayisi ye-USB3 enepulaki, awudingi ngisho ne-multiplexer ukuze ubambe ukuzungezisa - empeleni, awudingi ukutholwa kokuzungezisa. I-resistor eyodwa engu-5.1kΩ engalawuleki yanele ukudala i-USB3 flash drive exhuma ngqo embobeni ye-USB-C, noma ukudala i-adaptha ye-USB-C yowesilisa kuya kowesifazane we-USB-A 3.0. Ngokuya lapho amasokhethi ahamba khona, ungagwema ukusebenzisa i-multiplexer uma unokuxhuma kwamahhala kwe-USB3 ukuze unikele, okuyinto engekho yonke leyo. Angazi okwanele mayelana neziteshi ezimbili ze-USB3 ukuze ngiqiniseke ukuthi uma ishaneli ekabili i-USB3 isekela ukuxhumana okunjalo, kodwa ngicabanga ukuthi impendulo ethi “cha” ingase ibe ngaphezu kuka “yebo”!
I-DisplayPort (DP) iyisixhumi esibonakalayo esihle kakhulu sokuxhuma izibonisi ezinokulungiswa okuphezulu - idlule i-HDMI kumadeskithophu, ibusa indawo yokubonisa eyakhelwe ngaphakathi ngendlela ye-eDP, futhi iletha ukulungiswa okuphezulu ngekhebula elilodwa, ngokuvamile elingcono kune-HDMI. Ingaguqulelwa ku-DVI noma i-HDMI kusetshenziswa i-adaptha eshibhile esebenzisa indinganiso ye-DP++ futhi ayinanzuzo njenge-HDMI. Kunengqondo ukuthi umfelandawonye we-VESA usebenzisane neqembu le-USB ukusebenzisa ukwesekwa kwe-DisplayPort, ikakhulukazi njengoba ama-DisplayPort transmitters kuma-SoCs ethandwa kakhulu.
Uma usebenzisa idokhi ekhipha i-HDMI noma i-VGA, isebenzisa Enye Imodi ye-DisplayPort ngemuva kwezigcawu. Abaqaphi baya ngokuya beza nokokufaka kwe-DisplayPort nge-USB-C, futhi ngenxa yesici esibizwa nge-MST, ungakwazi ukuxhumanisa iziqaphi, zikunike ukucushwa kokuqapha okuningi ngekhebula elilodwa - ngaphandle uma usebenzisa iMacbook, njengoba i-Apple isilahlile. macOS. I-MST isekelwa ku-.
Futhi, iqiniso elithokozisayo - I-DP Alternate Mode ingenye Yezinye Izindlela ezimbalwa ezisebenzisa izikhonkwane ze-SBU eziphinde zenziwe kabusha ku-DisplayPort AUX ipheya. Ukuntuleka okuvamile kwamaphini we-USB-C kusho nokuthi izikhonkwane zokumisa ze-DP kufanele zikhishwe, ngaphandle kwemodi ehambisanayo ye-DP++ HDMI/DVI, ngakho wonke ama-adaptha e-USB-C DP-HDMI asebenza ngempumelelo e-DP-HDMI. Ukufihla ubuso - Ngokungafani ne-DP++, i-DP++ ikuvumela ukuthi usebenzise ukushintsha kwezinga ukuze uthole ukwesekwa kwe-HDMI.
Uma ufuna ukushintsha i-DisplayPort, cishe uzodinga i-multiplexer enikwe amandla i-DP, kodwa okubaluleke kakhulu, kufanele ukwazi ukuthumela imilayezo ye-PD yangokwezifiso. Okokuqala, yonke ingxenye “yesibonelelo/yesicelo enye imodi ye-DP” yenziwa nge-PD – azikho izinqamuleli ezanele. Awekho futhi izikhonkwane zamahhala ze-HPD, okuwuphawu olubalulekile ku-DisplayPort, ngakho-ke imicimbi ye-hotplug neyokukhipha isisu ithunyelwa njengemilayezo ngesixhumanisi se-PD. Sekushiwo lokho, akunzima kakhulu ukukusebenzisa, futhi ngicabanga ngokuqaliswa okusebenziseka kalula kwe-hacker - kuze kube yileso sikhathi, uma udinga ukusebenzisa i-DP Alternate Mode ukukhipha i-DP noma i-HDMI phezu kwembobo ye-USB-C, kukhona ama-chips afana I-CYPD3120 ekuvumela ukuthi ubhale i-firmware yalokhu.
Enye yezinto eyenza i-DP Alternate Mode igqame ukuthi inemizila emine yesivinini esiphezulu ku-USB-C, ekuvumela ukuthi uhlanganise uxhumano lwe-USB3 ohlangothini olulodwa lwembobo ye-USB-C kanye noxhumano olukabili lwe-DisplayPort ku-USB-C. okunye. Lena yindlela wonke amadokhu e-“USB3, ama-Peripherals, kanye ne-HDMI Out” asebenza ngayo. Uma ukulungiswa kwemizila emibili kuwumkhawulo kuwe, ungakwazi futhi ukuthenga i-adaptha ye-quad-lane - ngenxa yokuntuleka kwe-USB3, ngeke kube khona ukudluliswa kwedatha, kodwa ungathola ukulungiswa okuphezulu noma amanani ozimele ngemizila emibili ye-DisplayPort eyengeziwe.
Ngithola i-DisplayPort Alternate Mode ingenye yezinto ezihamba phambili nge-USB-C, kanti nakuba amafoni aphathekayo ashibhile (noma amashwa) angayisekeli, kuhle ukuba nedivayisi ekhona. Yiqiniso, ngezinye izikhathi inkampani enkulu ithola leyo njabulo ngokuqondile, njengoba kwenza i-Google.
Ikakhulukazi, nge-USB-C ungathola i-Thunderbolt 3, futhi maduze i-Thunderbolt 4, kodwa kuze kube manje yinhle kakhulu. I-Thunderbolt 3 ekuqaleni yayiwukucaciswa kokuphathelene okwagcina kuvuliwe kwatholakala yi-Intel. Ngokusobala awavuleki ngokwanele noma anenye i-caveat, futhi njengoba amadivayisi we-Thunderbolt 3 endle asakhiwa ngokukhethekile ngama-Intel chips, ngicabanga ukuthi ukuntuleka kokuncintisana kuyisizathu esenza amanani ahlale ezinzile. insimu yedijithali. Kungani ufuna amadivayisi we-Thunderbolt kwasekuqaleni? Ngaphezu kwesivinini esiphezulu, kunesinye isici sokubulala.
Uthola umkhawulokudonsa we-PCIe phezu kweThunderbolt kanye nokufika ku-4x komkhawulokudonsa! Lesi kube yisihloko esishisayo kulabo abadinga ukwesekwa kwe-eGPU noma isitoreji sangaphandle esisheshayo ngendlela yamadrayivu e-NVMe asetshenziswa abanye abaduni kuma-FPGA anamathiselwe kwi-PCIe. Uma unamakhompiyutha amabili anikwe amandla i-Thunderbolt (isibonelo, ama-laptops amabili), ungakwazi futhi ukuwaxhuma usebenzisa ikhebula elinikwe amandla i-Thunderbolt - lokhu kudala uxhumano lwenethiwekhi yesivinini esikhulu phakathi kwabo ngaphandle kwezingxenye ezengeziwe. Yebo, kunjalo, iThunderbolt ingadonsa kalula i-DisplayPort ne-USB3 ngaphakathi. Ubuchwepheshe be-Thunderbolt bunamandla kakhulu futhi bumnandi kubasebenzisi abathuthukile.
Kodwa-ke, konke lokhu kuphola kufinyelelwa nge-proprietary and complex technology stack. I-Thunderbolt akuyona into engadalwa kalula yi-hacker, nakuba othile kufanele ayizame ngolunye usuku. Futhi naphezu kwezici eziningi zedokhi ye-Thunderbolt, uhlangothi lwesofthiwe luvame ukudala izinkinga, ikakhulukazi uma kuziwa ezintweni ezifana nokuzama ukulala ukuze usebenze kukhompuyutha ephathekayo ngaphandle kokuphahlazeka umgogodla we-eGPU. Uma kungakabonakali okwamanje, ngibheke ngabomvu ukuthi i-Intel ikuhlanganise.
Ngilokhu ngithi “multiplexer”. Kuyini lokhu? Ngamafuphi, le ngxenye isiza ukuphatha ukuxhawula izandla ngesivinini esikhulu ngokuya ngokuzungezisa kwe-USB-C.
I-High-Speed Lane ingxenye ye-USB-C ethinteka kakhulu ngokuzungezisa imbobo. Uma imbobo yakho ye-USB-C isebenzisa i-High Speed Lane, uzodinga i-chip ye-multiplexer (multiplexer) ukuze ulawule ukujika okubili okungaba khona kwe-USB-C - ukuqondanisa umumo wezimbobo nezintambo kuzo zombili iziphetho nezamukeli zangempela zangaphakathi zesivinini esikhulu. . nama-transmitter afaniswa nedivayisi exhunyiwe. Kwesinye isikhathi, uma i-chip yesivinini esikhulu idizayinelwe i-USB-C, lawa ma-multiplexers angaphakathi kwe-chip yesivinini esikhulu, kodwa ngokuvamile angama-chip ahlukene. Ingabe ufuna ukwengeza usekelo lwe-Hi-Speed USB-C kudivayisi engasekeli i-Hi-Speed USB-C? Ama-Multiplexers azosekela imisebenzi yezokuxhumana enesivinini esikhulu.
Uma idivayisi yakho inesixhumi se-USB-C esine-High Speed Lane, uzodinga i-multiplexer - izintambo ezingaguquki namadivayisi anezixhumi awayidingi. Ngokuvamile, uma usebenzisa ikhebula ukuxhuma amadivayisi amabili anesivinini esiphezulu anezikhala ze-USB-C, zombili zizodinga i-multiplexer—ukulawula ukuzungezisa kwekhebula kuwumthwalo wedivayisi ngayinye. Kuzo zombili izinhlangothi, i-multiplexer (noma isilawuli se-PD esixhunywe ku-multiplexer) sizolawula isiqondiso sephinikhodi ye-CC futhi senze ngokufanele. Futhi, eziningi zalezi ziphindaphinda zisetshenziselwa izinhloso ezehlukene, kuya ngokuthi yini oyifunayo ethekwini.
Uzobona ama-multiplexer e-USB3 kumakhompyutha aphathekayo ashibhile asebenzisa kuphela i-USB 3.0 embotsheni yohlobo C, futhi uma isekela i-DisplayPort, uzoba ne-multiplexer enokufaka okwengeziwe ukuze uxube lawa masignali wedivayisi. Ku-Thunderbolt, i-multiplexer izokwakhiwa ku-Thunderbolt chip. Kubaduni abasebenza nge-USB-C kodwa abangenakho ukufinyelela ku-Thunderbolt noma abangadingi i-Thunderbolt, i-TI ne-VLI zinikeza inani lokuphindaphinda okuhle ngezinjongo ezihlukahlukene. Isibonelo, bengisebenzisa i-DisplayPort phezu kwe-USB-C muva nje, futhi i-VL170 (ibonakala iyingcweti engu-1:1 ye-TI's HD3SS460) ibukeka njenge-chip enhle yokusebenzisa i-DisplayPort + USB3 combo.
Ama-multiplexers e-USB-C asekela i-DisplayPort (njenge-HD3SS460) awakwenzi ngokwemvelo ukulawula iphinikhodi ye-CC futhi aphendule ukutholwa, kodwa lokho kuwumkhawulo ozwakalayo - i-DisplayPort idinga isixhumanisi se-PD esiqondene nohlelo lokusebenza, esibaluleke kakhulu. amakhono amaningi. Ingabe ujabulile nge-USB3 engadingi uxhumano lwe-PD? I-VL161 iyi-USB3 multiplexer IC elula enokufakwa kwe-polarity, ukuze ukwazi ukuchaza i-polarity ngokwakho.
Uma futhi ungadingi ukutholwa kwe-polarity - ingabe i-5v kuphela i-analog PD yanele izidingo zakho ze-USB3? Sebenzisa into efana ne-VL160 - ihlanganisa izamukeli ze-analog PD nemithombo, amandla okucubungula kanye nethrekhi enesivinini esiphezulu ehlangana konke endaweni eyodwa. Icwecwe langempela “Ngifuna i-USB3 phezu kwe-USB-C, ngifuna ukuthi yonke into ingiphathele yona”; isibonelo, amakhadi wokuthwebula we-HDMI yomthombo ovulekile wakamuva asebenzisa i-VL160 ezimbobeni zawo ze-USB-C. Ukuze ngikhulume iqiniso, asikho isidingo sokuthi ngikhiphe i-VL160 - kunenqwaba yama-microcircuits anjalo; “I-USB3 mux ye-USB-C, kwenze konke” cishe iwuhlobo oludume kakhulu lwe-chip ehlobene ne-USB-C.
Kukhona ezinye izindlela ze-USB-C zefa ezimbalwa. Eyokuqala, engingeke ngakhala ngayo, i-HDMI Enye Imodi; ivele ibeke izikhonkwane zesixhumi se-HDMI phezu kwezikhonkwane zesixhumi se-USB-C. Ingakunika i-HDMI phezu kwe-USB-C, futhi ibonakala itholakala kuma-smartphone isikhathi esifushane. Kodwa-ke, kufanele iqhudelane kalula nokuguqulela ku-HDMI DisplayPort Alternate Mode, kuyilapho ukuguqulwa kwe-HDMI-DP kuvame ukubiza futhi akukwazi ukusetshenziswa ngokuhambisana ne-USB 3.0 ngoba i-HDMI idinga amapheya amane ahlukene kanye nemithwalo yelayisense ye-HDMI, ngokusho kubonakala sengathi ukugqugquzela ukuthuthukiswa kwe-HDMI Alt Mode emhlabathini. Ngikholelwa ngempela ukuthi kufanele ihlale lapho ngoba angikholelwa ukuthi umhlaba wethu ungathuthukiswa ngokungeza i-HDMI eyengeziwe.
Kodwa-ke, enye iyathakazelisa impela - ibizwa ngeVirtualLink. Ezinye izinkampani ezinkulu zobuchwepheshe zisebenza ngamakhono e-USB-C ku-VR – phela kuhle kakhulu lapho ihedisethi yakho ye-VR idinga kuphela ikhebula elilodwa kuyo yonke into. Kodwa-ke, izibuko ze-VR zidinga ukubonisa okukabili kokucaca okuphezulu, ukuxhumana kwevidiyo enezinga eliphezulu, kanye noxhumo lwedatha olunesivinini esikhulu kumakhamera engeziwe nezinzwa, kanye nenhlanganisela evamile “ye-dual-link DisplayPort + USB3″ ayikwazi ukunikeza izici ezinjalo. ngaleso sikhathi. Futhi wenzani-ke
Ithimba le-VirtualLink lithi kulula: ungaxhuma amapheya amabili e-USB2 angasasebenzi kusixhumi se-USB-C futhi usebenzise izikhonkwane ezine ukuze uxhume i-USB3. Khumbula i-chip yokuguqula ye-USB2 iye ku-USB3 engikhulume ngayo esihlokweni esifushane engxenyeni yonyaka edlule? Yebo, inhloso yayo yasekuqaleni bekunguVirtualLink. Impela, lokhu kusetha kudinga ikhebuli yangokwezifiso ebiza kakhulu kanye namapheya amabili avikelekile angeziwe, futhi kudinga amandla afinyelela kwangu-27W kusuka ku-PC, okungukuthi ukuphuma kwe-9V, okungavamile ukubonakala kumashaja odonga e-USB-C noma kumadivayisi eselula. amandla. Umehluko phakathi kwe-USB2 ne-USB3 uyakhungathekisa kwabanye, kodwa ku-VR VirtualLink ibonakala iwusizo kakhulu.
Amanye ama-GPU eza nokusekelwa kwe-VirtualLink, kodwa lokho akwanele ngokuhamba kwesikhathi, namakhompyutha aphathekayo adume kabi ngokuvamise ukuntula izimbobo ze-USB-C nawo awakwenzi lokho. Lokhu kubangele i-Valve, umdlali oyinhloko esivumelwaneni, ukuba ahlehle ekungezeni ukuhlanganiswa kwe-VirtualLink ku-Valve Index, futhi yonke into yehla ukusuka lapho. Ngeshwa, i-VirtualLink ayizange idume. Kungaba enye indlela ethokozisayo - ikhebula elilodwa lingaba yinketho enhle kubasebenzisi be-VR, futhi ukudinga amandla kagesi aphezulu phezu kwe-USB-C nakho kuzosinika okungaphezu kuka-5V ngokusebenza kwe-PD. Amachweba - Awekho ama-laptops noma ama-PC anikeza lezi zici kulezi zinsuku. Yebo, isikhumbuzi nje - uma unembobo ye-USB-C kudeskithophu yakho noma kukhompuyutha ephathekayo, izokunikeza i-5V, kodwa ngeke uthole lutho oluphakeme.
Nokho, ake sibheke ohlangothini olukhanyayo. Uma uneyodwa yalawa ma-GPU anembobo ye-USB-C, izosekela kokubili i-USB3 ne-DisplayPort!
Into enhle nge-USB-C ukuthi abathengisi noma abaduni bangakwazi ukuchaza enye imodi yabo uma befuna, futhi ngenkathi i-adaptha izoba okobunikazi obulinganiselwe, empeleni kuseyimbobo ye-USB-C yokushaja nokudluliswa kwedatha. Ingabe ufuna i-Ethernet Alternate Mode noma i-Dual Port SATA? kwenzeni. Sezadlula izinsuku zokuzingela izixhumi ezingacacile kakhulu zamadivayisi akho njengoba idokhi ngayinye nesixhumi sokushaja sihlukile futhi singabiza ngaphezulu kuka-$10 sisinye uma kuvamile ngokwanele ukutholakala.
Akuzona zonke izimbobo ze-USB-C ezidinga ukusebenzisa zonke lezi zici, futhi eziningi azikwenzi lokho. Nokho, abantu abaningi bayakwenza, futhi njengoba isikhathi sihamba, sithola ukusebenza okwengeziwe okuvela ezimbobeni ezivamile ze-USB-C. Lokhu kuhlanganiswa nokumiswa kuzokhokha ngokuhamba kwesikhathi, futhi nakuba kuzoba nokuphambuka ngezikhathi ezithile, abakhiqizi bazofunda ukubhekana nakho ngobuchule.
Kodwa into eyodwa ebengihlale ngizibuza yona ukuthi kungani ukuzungezisa kwepulaki kungaphathwa ngokubeka izintambo ezithi + kanye – nezinhlangothi ezihlukene. Ngakho-ke, uma ipulaki ixhunywe ngendlela "engalungile", + izoxhunywa ku - futhi - izoxhunywa ku-+. Ngemva kokukhipha amakhodi kumamukeli, okumele ukwenze ukuhlehlisa izingcezu ukuze uthole idatha efanele.
Empeleni, inkinga ubuqotho besignali kanye ne-crosstalk. Cabanga, ake sithi, isixhumi samaphini angu-8, imigqa emibili kwezine, 1/2/3/4 kolunye uhlangothi no-5/6/7/8 kolunye, lapho u-1 ebhekene no-5. Ake sithi ufuna ipheya +/- thola /sakaza. Ungase uzame ukufaka i-Tx+ ku-pin 1, Tx- ku-pin 8, Rx+ ku-pin 4, kanye no-Rx- ku-pin 5. Ngokusobala, ukufaka ukubuyisela emuva kuphela ukushintshanisa okuthi +/-.
Kodwa isignali kagesi empeleni ayihambi ngaphesheya kwephinikhodi, ihamba phakathi kwesignali nokubuya kwayo endaweni kagesi. I-Tx-/Rx- kufanele kube “ukubuyisela” kwe-Tx+/Rx+ (futhi ngokusobala ngokuphambene nalokho). Lokhu kusho ukuthi amasiginali we-Tx ne-Rx ayaphambana.
“Ungazama” ukulungisa lokhu ngokwenza amasignali ahambisanayo angalingani - ngokuyisisekelo ubeke indiza yaphansi eqinile eduze kwesiginali ngayinye. Kodwa kulesi simo, ulahlekelwa ukungavikeleki komsindo wemodi ehlukile ehambisanayo, okusho ukuthi i-crosstalk elula esuka ku-Tx+/Rx- ebhekene nenye ayikhanseli.
Uma uqhathanisa lokhu nokubeka i-Tx+/Tx- kumaphini angu-1/2 no-7/8 kanye ne-Rx+/Rx- kumaphini angu-3/4 no-5/6 nge-multiplexer, manje amasiginali we-Tx/Rx awaweli futhi konke ukungqubuzana kubangelwa kothintana nabo i-Tx noma i-Rx, izoba yinto evamile kuwo womabili amapheya futhi inxeshezelwe kancane.
(Ngokusobala, isixhumi sangempela sizophinda sibe nezikhonkwane eziningi, angizange ngikhulume ngaso ngenxa yobufushane.)
> Ukuhlanganiswa kuletha ukuhambisana okunzima ukukusho, i-IMO lokho okulethwa yi-USB-C kuwumhlaba nje wokungahambelani okufihliwe okunzima ukukuqonda ku-tech-savvy njengoba imininingwane ingasho nokuthi yini engakwazi/engakwazi ukuyenza. futhi kuzoba kubi kakhulu njengoba ezinye izindlela zengezwa, futhi lawo makhebuli afanayo anezinkinga futhi…
Izixhumi eziningi zamandla angaphambi kwe-USB-C bekuyizixhumi zemiphongolo, ezishibhe kakhulu kune-USB-C. Nakuba izinhlobo eziningi zeziteshi zedokhi zingaba nezixhumi ezixakile eziyinkathazo, nazo zivame ukuba nokufinyelela okuqondile ku-PCI-E namanye amabhasi, futhi ngokuvamile zinenani elibalulekile lemizila - esheshayo kune-USB-C, okungenani uma kuqhathaniswa nesikhathi sakho. … I-USB-C bekungelona iphupho elibi kubageli ababefuna i-USB-2 kuphela, isixhumi esibizayo nje, nesixhumi sedokhu sasingalungile, kodwa lapho udinga izinto eziyinkimbinkimbi ngempela. Uma kukhulunywa ngamakhono esivinini esikhulu, i-USB-C iyiyisa kwelinye izinga lokusebenza.
Ngempela, lokho kwaba umbono wami futhi. Izinga livumela yonke into, kodwa akekho ozosebenzisa noma yini engenza kube nzima ukuthi noma imaphi amadivaysi amabili e-USB-C asebenze ndawonye. Sengidlule kukho; Nginikeze amandla ithebhulethi yami nge-adaptha yamandla ye-USB-A kanye nekhebula le-USB-A ukuya ku-USB-C iminyaka. Lokhu kungivumela ukuthi ngiphathe i-adaptha yethebhulethi nefoni yami. Ngithenge i-laptop entsha futhi i-adaptha endala ngeke iyikhokhise - ngemva kokufunda okuthunyelwe kwangaphambilini, ngabona ukuthi cishe idinga enye yama-voltage aphezulu i-adaptha ye-USB-A engakwazi ukukunikeza. Kodwa uma ungayazi imininingwane yalesi sikhombimsebenzisi esiyinkimbinkimbi kakhulu, ngakho-ke akucaci ukuthi kungani ikhebula elidala lingasebenzi.
Ngisho nomhlinzeki oyedwa akakwazi ukwenza lokhu. Sathola konke kuDell ehhovisi. I-laptop ye-Dell, i-Dell docking station (i-USB3), kanye ne-monitor ye-Dell.
Kungakhathaliseki ukuthi iyiphi idokhu engiyisebenzisayo, ngithola iphutha elithi “Bonisa umkhawulo wokuxhumeka”, iphutha “lomkhawulo wokushaja”, isikrini esisodwa kuphela kwezimbili esisebenzayo, noma ngeke sixhume kwanhlobo. Kuyisiphithiphithi.
Ukubuyekezwa kwe-Firmware kufanele kwenziwe ebhodini lomama, esiteshini sokumisa, futhi abashayeli kufanele babuyekezwe. Ekugcineni yenze into embi yasebenza. I-USB-C ihlezi ibuhlungu.
Ngisebenzisa iziteshi ze-non-Dell futhi yonke into ihambe kahle! =D Ukwenza idokhu ehloniphekile ye-USB-C akubonakali kunzima kangako - ngokuvamile kusebenza kahle kakhulu uze uhlangabezane nezinto ezingavamile ze-Thunderbolt, futhi nalapho kuba khona izinkinga endaweni “yepulaki, khipha, sebenza”. Ngeke ngiqambe amanga, okwamanje bengifuna ukubona isikimu sebhodi lomama lekhompuyutha ephathekayo yakwaDell enalezi ziteshi zokumisa.
U-Arya uqinisile. Zonke izinkinga zanyamalala lapho ngithenga isihlukanisi esisebenza nge-USB-C esishibhile esivela e-Amazon. Amakhibhodi, amakhamera ewebhu, ama-dongle e-USB angaxhunywa, imonitha ixhumeke embobeni ye-USB-C, HDMI, noma ye-DP kukhompuyutha ephathekayo, futhi isilungele ukuhamba. Ngatshelwa ukuthi ngenzeni umfana wakwa-IT owathi idokodo likaDell aliyifanele imali.
Cha, lezi izilima zikaDell - ngokusobala banqume ukwenza umkhiqizo ungahambisani ne-USB-C lapho besebenzisa isixhumi esifanayo.
Yebo, uma ungibuza, idivayisi efana nethebhulethi idinga ukucaciswa kabanzi mayelana nokuthi "kungani ingashajiwe ngokugcwele". Umlayezo we-pop-up “Okungenani ishaja engu-9V @ 3A ye-USB-C edingekayo” uzoxazulula izinkinga zabantu ezifana nalezi futhi wenze lokho kanye okulindelwe ngumkhiqizi wethebhulethi. Kodwa-ke, asikwazi nokukholwa ukuthi noma iyiphi kuzo izokhipha isibuyekezo esisodwa se-firmware ngemuva kokuthi idivayisi isidayiswe.
Hhayi kuphela eshibhile, kodwa futhi kunamandla. Zingaki izixhumi ze-USB eziphukile ozibonile kumadivayisi ahlukahlukene? Ngivame ukwenza lokhu - futhi ngokuvamile idivayisi enjalo ilahlwa, ngoba akunakwenzeka ngokomnotho ukuyilungisa ...
Izixhumi ze-USB, eziqala nge-Micro USB, bezintekenteke kakhulu, futhi kudingeke ukuthi zihlale zixhumeke futhi uzikhiphe, ngokuvamile abantu abangaziqondi kahle, basebenzise amandla amaningi, bezinyakazisa ngapha nangapha, kwenza izixhumi zibe zimbi kakhulu. Ukuze uthole idatha, lokhu kungase kubekezeleleke, kodwa uma kubhekwa ukuthi i-USB-C manje isisetshenziselwa ukunika amandla yonke into kusukela kumawashi ahlakaniphile kuye kuwo wonke amakhompyutha aphathekayo kanye nazo zonke izinhlobo zamagajethi e-elekthronikhi angasebenzisi nhlobo idatha, izixhumi ezilimele zizovama kakhulu. . Lapho isikhathaza kakhulu - futhi ngaphandle kwesizathu esihle.
Kulungile, ngibone isixhumi somphongolo esisodwa esiphukile futhi kulula ukusilungisa (ngaphandle kwenguqulo ye-Dell BS, isebenza kuphela kushaja yobunikazi engakwazi ukuxhumana nayo, okuyinto enhle kakhulu, ungayilimaza ngisho noma awukaze ugibele ibhayisikili..) Ngisho nomkhandi onolwazi, isixhumi se-USB-C sizoba yi-PITA, enendawo ye-PCB eyengeziwe, izikhonkwane ze-solder ezincane...
Izixhumi zemiphongolo ngokuvamile zilinganiselwe ingxenye yomjikelezo (noma ngaphansi) wezixhumi ezivamile ze-USB-C. Lokhu kungenxa yokuthi iphinikhodi emaphakathi iyagobeka isikhathi ngasinye lapho ifakwa, futhi nge-USB, ingalo yesigebezo iba mfushane. Ngibone ojeke abaningi bemiphongolo bonakele ngokusetshenziswa.
Esinye sezizathu ezenza i-USB-C ibonakale ingathembeki kangako izixhumi ezishibhile noma izintambo. Uma uthola umkhiqizo obukeka “usesitayeleni” noma “upholile” onemijovo yokubumba noma yini, cishe kuwubuwula. Itholakala kuphela kubakhiqizi abakhulu bezintambo ezinemininingwane nemidwebo.
Esinye isizathu ukuthi usebenzisa i-USB-C ngaphezu kwezixhumi ezimise okomgqomo. Amafoni axhuma futhi anqamule nsuku zonke, kwesinye isikhathi izikhathi ezimbalwa.
