Ibisobanuro kuri TCA9555
Iyi 16-bit ya I / O yagura ya bisi y'imirongo ibiri (I2C) yagenewe 1.65-V kugeza 5.5-V VCCoperation.Itanga rusange-intego ya kure ya I / O kwaguka kumiryango myinshi ya microcontroller viathe I2C.
TCA9555 igizwe na 8-bit Iboneza (ibyinjijwe cyangwa ibisohoka byatoranijwe), icyambu cyinjira, icyambu gisohoka, hamwe na Polarity Inversion (ikora cyane cyangwa ikora hasi).Ku mbaraga kuri, I / Os zashyizweho nkibisubizo.Sisitemu shobuja arashobora gukora I / Os nkibisubizo byinjiza byanditse kuri bits ya I / O.Ibyatanzwe kuri buri cyinjijwe cyangwa ibisohoka bibikwa mubisubizo byinjira cyangwa bisohoka.Ubuharike bwibicuruzwa byinjira byinjira birashobora guhindurwa hamwe na rejisitiri ya Polarity Inversion.
TCA9555 ihwanye na TCA9535, usibye gushyiramo imbere ya I / O gukurura-gukurura, gukurura I / O hejuru cyane iyo byashyizweho nkinjiza na andriveri.
Amapine atatu yibikoresho (A0, A1, na A2) bikoreshwa mugutegura aderesi ya I2C, itanga ibikoresho bigera ku munani bya TCA9555 gusangira bisi imwe ya I2C cyangwa SMBus.Aderesi I2C ihamye ya TCA9555 ni kimwe na PCF8575, PCF8575C, naPCF8574, yemerera abagera kuri umunani muri sisitemu zose hamwe kugirango basangire bisi imwe ya I2C cyangwa SMBus.
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
