Ibisobanuro kuri TCA9548A
Igikoresho cya TCA9548A gifite umunani uhinduranya ibyerekezo byombi bishobora kugenzurwa na I.2Bus.Abafana ba SCL / SDA hejuru yimbere kugeza umunani, cyangwa imiyoboro.Umuyoboro uwo ariwo wose wa SCn / SDn cyangwa guhuza imiyoboro irashobora guhitamo, bigenwa nibiri mubitabo byabigenewe.Izi nzira zo hasi zirashobora gukoreshwa mugukemura I.2C gukemura amakimbirane.Urugero, niba ibyuma umunani byerekana ubushyuhe bukenewe mubisabwa, sensor imwe ihuza kuri buri muyoboro: 0-7.
Sisitemu shobuja arashobora gusubiramo TCA9548A mugihe habaye igihe cyashize cyangwa ibindi bidakwiye mukwemeza hasi mubisubizo bya RESET.Muri ubwo buryo, imbaraga-onreset ihitamo inzira zose kandi itangiza I.2C / SMBus statemachine.Kwemeza GUSUBIZA bitera gusubiramo kimwe no gutangira kubaho bitabaye ngombwa kumanura igice.Ibi bituma gukira bigomba kuba bimwe mumanukaI2Bisi zihagarara mumwanya muto.
Irembo ryambukiranya ryubatswe ryubatswe kuburyo pin ya VCC ishobora gukoreshwa kugirango igabanye ingufu nini cyane, inyuzwa na TCA9548A.Kugabanya umuvuduko mwinshi wa voltage yemerera gukoresha ingufu za bisi zitandukanye kuri buri jambo, kugirango 1.8-V, 2.5-V cyangwa 3.3-V ibice bishobora kuvugana nibice 5-V, nta burinzi bwongeyeho.Kurwanya gukurura hanze bikurura bisi hejuru yumubyigano wa voltage kuri buri muyoboro.Amapine yose I / O yihanganira 5-V.
1. Ni bande bakozi mu ishami rya R & D?Ni ubuhe bushobozi bwawe?
-R & D Umuyobozi: gutegura gahunda yigihe kirekire yikigo no gusobanukirwa icyerekezo cyubushakashatsi niterambere;Kuyobora no kugenzura ishami rishyira mubikorwa ingamba za sosiyete na gahunda ya R&D yumwaka;Kugenzura iterambere ryibicuruzwa no guhindura gahunda;Shiraho ibicuruzwa byiza byubushakashatsi niterambere, kugenzura no guhugura abakozi ba tekiniki bijyanye.
Umuyobozi wa R & D: kora ibicuruzwa bishya R & D hanyuma werekane ko bishoboka gahunda;Kugenzura no gucunga iterambere nubuziranenge bwakazi;Kora ubushakashatsi ku bicuruzwa bishya kandi utange ibisubizo bifatika ukurikije ibyo umukiriya asabwa mubice bitandukanye
Abakozi & gukusanya: gukusanya no gutondekanya amakuru yingenzi;Porogaramu ya mudasobwa;Gukora ubushakashatsi, ibizamini nisesengura;Tegura ibikoresho nibikoresho byo kugerageza, kugerageza no gusesengura;Andika amakuru yo gupima, gukora ibarwa no gutegura imbonerahamwe;Kora ubushakashatsi bwibarurishamibare
2. Niki gitekerezo cyawe cyo gukora ubushakashatsi nibitekerezo byiterambere?
- Igitekerezo cyibicuruzwa no guhitamo ibicuruzwa nibisobanuro byerekana ibicuruzwa nibishushanyo mbonera byumushinga no kugerageza ibicuruzwa bitezimbere no kwemeza isoko
