Mhedziso Yekuchinja mu USB Interface

Pakati pazvo, yazvino USB4 chiyero (senge USB4 Cable, USBC4 Ku USB C) parizvino inotsigira Type-C mapindiro. Zvichakadaro, USB4 inowirirana neakawanda mainterface/protocol anosanganisira Thunderbolt 3 (40Gbps Data), USB, Display Port, uye PCIe. Zvimiro zvayo zvekutsigira 5A 100W USB C Cable magetsi uye USB C 10Gbps (kana USB 3.1 Gen 2) kutapurirana kwedata kunoisa hwaro hwekuzivikanwa kukuru.

Muchidimbu nezve Type-A/Type-B, Mini-A/Mini-B, uye Micro-A/Micro-B

1) Mamiriro eMagetsi eType-A uye Type-B
Iyo pinout inosanganisira VBUS (5V), D-, D+, uye GND. Nekuda kwekushandiswa kwekusiyanisa chiratidzo chekufambisa, iyo yekusangana dhizaini ye USB 3.0 A Male uye USB 3.1 Type A inotungamira kubatana kwesimba (VBUS/GND kureba), ichiteverwa nemitsara yedata (D-/D + ipfupi).
2) Magetsi Maitiro eMini-A/Mini-B uye Micro-A/Micro-B
Mini USB uye Micro USB (senge USB3.1 Micro B TO A) ine mashanu ekubatika: VCC (5V), D-, D+, ID, uye GND. Kuenzaniswa ne USB 2.0, imwe ID mutsara inowedzerwa kutsigira USB OTG mashandiro.
3) USB OTG Interface (Inogona kuita seHOST kana DEVICE)
USB yakakamurwa kuita HOST (host) uye DEVICE (kana muranda). Mimwe michina ingangoda kuita seHOST dzimwe nguva uye seDEVICE pane dzimwe nguva. Kuve nemadoko maviri e USB kunogona kuita izvi, asi kutambisa zviwanikwa. Kana imwe USB chiteshi ichigona kuita senge HOST uye DEVICE, zvingave zviri nyore. Saka, USB OTG yakagadzirwa.
Zvino mubvunzo unomuka: Ko USB OTG interface inoziva sei kana ichifanira kushanda se HOST kana DEVICE? Mutsetse wekuona ID unoshandiswa pakuita kweOTG (iyo yakakwira kana yakaderera nhanho yemutsara weID inoratidza kuti USB port iri kushanda muHOST kana DEVICE mode).
ID = 1: Iyo OTG mudziyo unoshanda munhapwa modhi.
ID = 0: Chishandiso cheOTG chinoshanda mune yekugamuchira mode.
Kazhinji, ma USB anodzora akasanganiswa mumachipi anotsigira OTG mashandiro uye anopa USB OTG interface (yakabatana kune USB controller) yeMini USB kana Micro USB uye mamwe mainterface ane ID mutsara kuti uiswe uye ushandiswe.

Kana paine chete Mini USB interface (kana Micro USB interface), uye kana iwe uchida kushandisa iyo OTG host modhi, ipapo iwe unozoda OTG tambo. Semuenzaniso, iyo OTG tambo yeMini USB inoratidzwa pazasi mumufananidzo: Sezvauri kuona, iyo Mini USB OTG tambo ine imwe magumo se USB A socket uye imwe magumo seMini USB plug. Isa iyo Mini USB plug muMini USB OTG interface yemuchina, uye yakabatana USB mudziyo unofanirwa kubatirwa mu USB A socket kune imwe magumo. Somuenzaniso, USB flash drive. Iyo USB OTG tambo inodzikisa iyo ID mutsara, saka muchina unoziva kuti unofanirwa kuita semuenzi kuti ubatanidze kune yekunze muranda mudziyo (senge USB flash drive).
