Incazelo ye-TCA9555
Lesi sandisi se-16-bit I/O sebhasi elinemigqa emibili eqondiswa kabili(I2C) yakhelwe ukusebenza okungu-1.65-V kuya ku-5.5-V VCCoperation.Ihlinzeka ngokunwetshwa okukude kwenhloso evamile ye-I/O yemindeni eminingi yama-microcontroller ngokusebenzisa isixhumi esibonakalayo se-I2C.
I-TCA9555 iqukethe ukucushwa okungu-8-bit okubili (okukhetha okokufaka noma okukhiphayo), Imbobo yokufaka, Imbobo yokukhipha, kanye ne-Polarity Inversion (ukubhaliswa okusebenzayo okuphezulu noma okusebenzayo okuphansi).Uma ikhanya, ama-I/O alungiswa njengokungenayo.Umphathi wesistimu angakwazi ukunika amandla ama-I/O njengokufaka noma okokukhiphayo ngokubhalela izingcezu zokucushwa ze-I/O.Idatha yokokufaka ngakunye noma okukhiphayo igcinwa kurejista Yokokufaka noma Yokukhiphayo.I-polarity yerejista ye-Input Port ingaguqulwa ngerejista ye-Polarity Inversion.
I-TCA9555 iyafana ne-TCA9535, ngaphandle kokufakwa kwe-internalI/O pull-up resistor, edonsa i-I/O ibe phezulu ezenzakalelayo lapho icushwa njenge-input andundriven.
Izikhonkwane ezintathu zehadiwe (A0, A1, kanye ne-A2) zisetshenziselwa ukuhlela ikheli le-I2C, elivumela amadivayisi afinyelela kwayisishiyagalombili e-TCA9555 ukwabelana ngebhasi elifanayo le-I2C noma i-SMBus.Ikheli le-I2C elingaguquki le-TCA9555 liyafana ne-PCF8575, PCF8575C, ne-PCF8574, livumela kufikela kwayisishiyagalombili kulawa madivayisi kunoma iyiphi inhlanganisela ukwabelana ngebhasi elifanayo le-I2C noma i-SMBus.
1. Obani abasebenzi bomnyango wakho we-R & D?Yiziphi iziqu zakho?
-R & D Umqondisi: yenza uhlelo lwesikhathi eside lwe-R & D lwenkampani futhi babambe isiqondiso socwaningo nentuthuko;Qondisa futhi uqondise umnyango we-r&d ukuze usebenzise isu le-r&d lenkampani kanye nohlelo lonyaka lwe-R&D;Lawula inqubekelaphambili yokuthuthukiswa komkhiqizo futhi ulungise uhlelo;Misa ithimba locwaningo lomkhiqizo elihle kakhulu nelokuthuthukisa, abacwaningi mabhuku kanye nokuqeqeshwa okuhlobene nabasebenzi bezobuchwepheshe.
Umphathi we-R & D: yenza uhlelo olusha lwe-R & D futhi ubonise ukuthi kungenzeka uhlelo;Ukugada nokuphatha inqubekelaphambili kanye nekhwalithi yomsebenzi we-r&d;Cwaninga ukuthuthukiswa komkhiqizo omusha futhi uphakamise izixazululo ezisebenzayo ngokuvumelana nezidingo zamakhasimende emikhakheni ehlukene
Abasebenzi be-R&d: baqoqa futhi balungise idatha ebalulekile;Uhlelo lwekhompyutha;Ukwenza izivivinyo, izivivinyo kanye nokuhlaziya;Lungiselela izinto zokwakha kanye nezinto zokusebenza zokuhlola, izivivinyo nokuhlaziya;Rekhoda idatha yokulinganisa, yenza izibalo futhi ulungiselele amashadi;Yenza izinhlolovo zezibalo
2. Uthini umbono wakho wocwaningo nokuthuthukiswa komkhiqizo?
- Ukwakhiwa komkhiqizo kanye nomqondo wokukhethwa komkhiqizo kanye nokuhlolwa kwencazelo yomkhiqizo kanye nomklamo wepulani yephrojekthi kanye nokuthuthukiswa kokuhlolwa komkhiqizo kanye nokwethulwa kokuqinisekisa emakethe
