Inkcazelo ye-TCA9548A
Isixhobo se-TCA9548A sineenguqu ezisibhozo zokuguqulela ezimbini ezinokulawulwa nge-I.2C ibhasi.I-SCL / SDA isibini esinyukayo sabalandeli ukuya kwizibini ezisibhozo ezisezantsi, okanye iziteshi.Naliphi na itshaneli ye-SCn/SDn okanye indibaniselwano yamajelo anokuthi axutywe, agqitywe yimixholo yerejista yolawulo enokucwangciswa.La majelo asezantsi angasetyenziselwa ukusombulula i-I2Iingxabano zentetho yamakhoboka.Umzekelo, ukuba i-sensor yedijithali efanayo iyafuneka kwisicelo, enye inzwa inokudityaniswa kwitshaneli nganye: 0-7.
Inkosi yesistim inokusetha kwakhona i-TCA9548A xa kwenzeka ixesha okanye enye into engafanelekanga ngokuqinisekisa igalelo eliphantsi kwi-RESET.Ngokufanayo, ukusetwa kwakhona kwamandla kuyeka ukukhetha onke amajelo kwaye kuqalise i-I2C/SMBus statemachine.Ukuqinisekisa ukuba iRESET ibangela ukusetha ngokutsha okufanayo kunye nokuqaliswa ukuba kwenzeke ngaphandle kokunciphisa indawo.Oku kuvumela recovery kufuneka omnye we downstreamI2Iibhasi ze-C zixinga kwimeko ephantsi.
Amasango okudlula okutshintsha akhiwe ukwenzela ukuba i-pin ye-VCC ingasetyenziselwa ukunciphisa umbane ophezulu ophezulu, ogqithiswa yi-TCA9548A.Ukunciphisa awona mandla ombane aphezulu aphezulu kuvumela ukusetyenziswa kwamandla ombane ebhasi ahlukeneyo kwisibini ngasinye, ukuze i-1.8-V, 2.5-V okanye i-3.3-V iinxalenye zikwazi ukunxibelelana neenxalenye ze-5-V, ngaphandle kokhuseleko olongezelelweyo.Izichasi zokutsala zangaphandle zitsala ibhasi ukuya kwinqanaba lombane elifunekayo kwitshaneli nganye.Zonke izikhonkwane ze-I/O zinonyamezelo lwe-5-V.
1. Ngoobani abasebenzi kwisebe lakho le-R & D?Ziziphi iziqinisekiso zakho?
-R & D UMlawuli: yenza isicwangciso sexesha elide seR & D senkampani kwaye ubambe isikhokelo sophando kunye nophuhliso;Ukukhokela kunye nokulawula isebe le-r&d ukuphumeza isicwangciso se-r&d yenkampani kunye nesicwangciso sonyaka se-R&D;Lawula inkqubela phambili yophuhliso lwemveliso kwaye uhlengahlengise isicwangciso;Misela uphando lwemveliso egqwesileyo kunye neqela lophuhliso, uphicotho kunye noqeqesho olunxulumene nabasebenzi bobugcisa.
Umphathi we-R & D: yenza imveliso entsha ye-R & D isicwangciso kwaye ubonise ukwenzeka kwesicwangciso;Ukongamela kwaye ulawule inkqubela kunye nomgangatho womsebenzi we-r&d;Phanda ngophuhliso lwemveliso entsha kwaye ucebise izisombululo ezisebenzayo ngokweemfuno zabathengi kwiinkalo ezahlukeneyo
Abasebenzi be-R&d: ukuqokelela kunye nokusombulula iinkcukacha eziphambili;inkqubo yeKhompyutha;Ukuqhuba iimvavanyo, iimvavanyo kunye nohlalutyo;Lungisa izixhobo kunye nezixhobo zovavanyo, iimvavanyo kunye nohlalutyo;Ukurekhoda idatha yokulinganisa, yenza izibalo kwaye ulungiselele iitshathi;Yenza uphando lwamanani
2. Yintoni uphando lwakho lwemveliso kunye nombono wophuhliso?
-Umbono wemveliso kunye nokukhethwa kwemveliso kunye novavanyo lwenkcazo yemveliso kunye noyilo lwesicwangciso seprojekthi kunye novavanyo lwemveliso kunye nokuqinisekiswa kokuqaliswa kwintengiso
