Sezvaunoziva, kune akawanda akasiyana ezvekubatanidza pane mamacomputer mamaboard yekubatanidza eripheral uye zvakamisikidzwa zvikamu. Pakati pezviteshi zvese zviri USB 2.0 uye USB 3.0, iyo inoshandira chiratidzo uye simba kubva kune yakavakirwa-mukubatana. Aya maviri shanduro zvakasiyana kwete kwete chete nehunyanzvi hunhu, asi zvakare maonero ezvinyorwa pane amaibhodhi. Munyaya yanhasi, tinoda kuvasangana navo zvakadzama.
Onawo: Chii chinoita kuti amai
Kufunga kweUSB 2.0 uye USB 3.0 connectors pane amaibhodhi
Nehurombo, hapana kana imwe dhizaini yemakumbo ese uye mafambisirwo evanobatanidza, sezvo tekinoroji yekugadzira kwavo haina kugadzirwa. Nekuda kweizvozvo, iyo chiyero chingave chakasiyana pane imwe neimwe muenzaniso wembambo. Mumufananidzo uri pazasi, unoona schematic pluut ye USB plug ine color dhizaini yekuonana kwega kwega. Izvo zvinobva pane izvi zviratidzo zvechiromarara kuti isu tichadzoserwa pamwe nekuwedzera kuongororwa kwevanobatanidza pane amaibhodhi.
USB 2.0
Ngatitangei neyakajairika USB 2.0. Haasi ese ekisheni anogadzira isa New USB 3.0 kana 3.1 inobatanidza kumabhodhi avo, asi zvakati wandei zvekare shanduro yekare 2.0 inofanira kuwanikwa muchikepe. Iyo Pinout inotaridzika yakapusa, nekuti chinhu chinongova chegumi chero kana makumbo esimbi. Teerera kumufananidzo uri pazasi. Iko kune mamiriro ezvinhu emamiriro ezvinhu ese aya mafambisirwo.
Zvino ngatitorei tendeuka pamwe chete nemumwe wavo kuti vashandisi vepacheki havanzwisisi vanonzwisisa mazita:
- 1 uye 2. Zvitsvuku uye zvine 5V, VCC kana Mazita emagetsi. Ane mhosva yekupa simba;
- 3 uye 4. Yakagoverwa nechena uye inenge kwese kwese inoratidzwa se- - mafambisirwo e data kutamiswa neyakagadzirirwa.
- 5 ne 6. Green color, Synfananidzira zita D + - Bata Contain neakapomerwa mhosva yakanaka;
- 7, 8 uye 10. Kazhinji, pasi rinosiyaniswa mune dema, uye zita rekubata rinoenderana neGND.
Iwe unogona kuona kusavapo kwekusangana kwepfumbamwe. Izvo hazvisizvo, sezvo nzvimbo ino ichishanda seiyi kiyi kune iyo pfungwa yekubatanidza zvakanyatsobatanidza waya kune contictor.
Mushure mekunyadziswa nekuteerera kwevose vanobvunzana, iwe unogona chete kubatanidza waya kwavari, kupihwa zvese zvekutaura zvakaratidzwa. Panguva imwecheteyo, porlarity inofanira kucherechedzwa, nekuti haisi pasina, yakaratidzwawo mu schematic dhizaini.
USB 3.0.
Rudzi rweUSB 3.0 runobatana nemazuva ano, uye zvakawanda uye zvisingasviki matsva mauto ane makumbo akati wandei akadai, izvo zvakabatana kuburikidza nemafambisirwo akagoverwa zvakananga izvi. Chimiro chechiteshi ichi chinonyanya kuomarara, nekuti vhezheni 3.0 ine yakawanda yehunyanzvi hunyanzvi uye inotsigira tekinoroji matsva.
Pamusoro apa iwe wakaona schematic pinout yeChinongedze 3.0, inosara chete kuti isurasitasina ese maonerwo mune mavara vhezheni:
- 2. Iyo nyowani yekubata ine chekuita nekuzivikanwa inowanzo kuratidzwa negrey uye ine zita rekufananidzira id;
- 1 uye 4. Inta_p2_d + uye intta_p1_d +, zvichiteerana. Yatojaira pini yekufambisa yedata kuendesa nemhosva yakanaka;
- 3 ne 6. Inta_p2_d- uye IntA_P1_D-. Yakarongedzwa waya yekufambisa yaayoya nemhosva isina kunaka;
- 5 neUsfupasi, seyakajairwa, yakanyorwa ne grey uye yakanyorwa gnd;
- 7 uye 10. Kumwe kusangana neyekuwedzera chiratidzo chekutapurirana kwedata kuburikidza neTX. 7 Inonzi IntA_P2_SstX +, uye Nhamba 10 - Inta_p1 +;
- 9 uye 12. Zvakafanana, asi ne "minus" chiratidzo uye nhungamiro yeInta_p2_sstx- uye Inta_p1_Sstx-;
- 11 uye 14. Nyika;
- 13 uye 16. Kuwana RX data neyekupa mhosva uye zita reInta_p2_srx + uye inta_p1 +;
- 15 Uye 18. RX CE ISINA Sign. Mazita - inta_p2_srx uye inta_p1_srx-;
- 17 uye 20. Makataridzwa mutsvuku uye ane basa rekupa simba. Iva neyekufananidzira vbus.
Sezvineiwo mune yakapfuura connector, imwe yekuonana isipo, uye nzvimbo iyi isina chinhu inoita seiyi kiyi. Mune iyi sarudzo, hapana kamuri ine gumi nemapfumbamwe. Mukuwedzera, iwe unogona kuona kuwedzera kweNew Contacts kuendesa RX uye TX data. Iyi steam inoshandiswa kana ichiratidza uye kupinda ruzivo pane serial interface uye yava mwero mune zvimwe zvakafanana zvirongwa.
Adapta ne USB 2.0 kusvika 3.0
Pamusoro iwe wanga uchiziva iyo pinout yezvinhu zvese uye kurondedzerwa kwakadzama kweumwe neumwe wavo. Iye zvino tinoda kuburitsa mufananidzo mudiki wechiSchematic weVashandisi vanofarira kubatanidza kana kugadzira adapta ne USB 2.0 kusvika 3.0 kusvika 3.0 kusvika 3.0. Hatisi kuzotonga zvakadzama nheyo yekugadzira cheni yakadaro, seiyi inyaya yechinyorwa chakapararira
Sechikamu chechinyorwa ichi, isu takarangarira kuendesa kweUSB connector pane amaibhodhi. Kana iwe uchifarira kuongororwa kwakafanana kwezvimwe zvinhu zvemakombiyuta, tinokupa zano kuti uverenge zvinyorwa zvemunhu pane zvinotevera zvinongedzo.
