Incamake yimpinduka muri USB Imigaragarire

Muri byo, USB4 igezweho (nka USB4 Cable, USBC4 Kuri USB C) kuri ubu ishyigikira gusa Type-C. Hagati aho, USB4 ihujwe ninteruro nyinshi / protocole harimo Thunderbolt 3 (Data 40Gbps Data), USB, Port Port, na PCIe. Ibiranga gushyigikira 5A 100W USB C Umugozi wamashanyarazi hamwe na USB C 10Gbps (cyangwa USB 3.1 Gen 2) kohereza amakuru byashizeho urufatiro rwo kumenyekanisha kwinshi.

Incamake yubwoko-A / Ubwoko-B, Mini-A / Mini-B, na Micro-A / Micro-B

1) Ibiranga amashanyarazi Ubwoko-A na Ubwoko-B
Pinout irimo VBUS (5V), D-, D +, na GND. Bitewe no gukoresha ibimenyetso bitandukanye byohereza, igishushanyo mbonera cya USB 3.0 Umugabo na USB 3.1 Ubwoko A bushyira imbere guhuza imbaraga (VBUS / GND ni ndende), hagakurikiraho imirongo yamakuru (D- / D + ni ngufi).
2) Ibiranga amashanyarazi Mini-A / Mini-B na Micro-A / Micro-B
Mini USB na Micro USB (nka USB3.1 Micro B TO A) bafite imibonano itanu: VCC (5V), D-, D +, ID, na GND. Ugereranije na USB 2.0, umurongo winyongera wongeyeho kugirango ushyigikire imikorere ya USB OTG.
3) Interineti ya USB OTG (Irashobora gukora nka HOST cyangwa DEVICE)
USB igabanijwemo HOST (host) na DEVICE (cyangwa imbata). Ibikoresho bimwe birashobora gukenera gukora nka HOST mugihe kimwe na DEVICE mubindi bihe. Kugira ibyambu bibiri bya USB birashobora kubigeraho, ariko ni uguta umutungo. Niba icyambu kimwe USB gishobora gukora nka HOST na DEVICE, byaba byiza cyane. Gutyo, USB OTG yaratejwe imbere.
Noneho ikibazo kivutse: Nigute interineti ya USB OTG yamenya niba igomba gukora nka HOST cyangwa DEVICE? Umurongo wo kumenya indangamuntu ukoreshwa mubikorwa bya OTG (urwego rwo hejuru cyangwa ruto rwo kumurongo w indangamuntu yerekana niba icyambu cya USB gikora muburyo bwa HOST cyangwa DEVICE).
ID = 1: Igikoresho cya OTG gikora muburyo bwabacakara.
ID = 0: Igikoresho cya OTG gikora muburyo bwakiriwe.
Mubisanzwe, USB igenzura yinjijwe muri chips ishyigikira imikorere ya OTG kandi igatanga USB ya OTG (ihujwe na USB mugenzuzi) kuri Mini USB cyangwa Micro USB hamwe nandi masura hamwe numurongo w'indangamuntu ugomba kwinjizwamo no gukoreshwa.

Niba hari Mini USB imwe gusa (cyangwa Micro USB interineti), kandi niba ushaka gukoresha uburyo bwa OTG bwakiriye, noneho uzakenera umugozi wa OTG. Kurugero, umugozi wa OTG kuri Mini USB urerekanwa hepfo mumashusho: Nkuko mubibona, umugozi wa Mini USB OTG ufite impera imwe nka USB A sock naho indi ikarangira nka Mini USB icomeka. Shyiramo Mini USB icomeka muri Mini USB OTG ya mashini, hanyuma igikoresho cya USB gihujwe kigomba gucomeka muri USB A sock kurundi ruhande. Kurugero, USB flash ya USB. Umugozi wa USB OTG uzagabanya umurongo w'indangamuntu, imashini rero izi ko igomba gukora nka host kugirango ihuze ibikoresho byabacakara bo hanze (nka USB flash ya USB).
