Chithunzi cha TCA9548A
Chipangizo cha TCA9548A chili ndi masiwichi asanu ndi atatu omasulira omwe amatha kuwongoleredwa kudzera mu I.2C basi.The SCL/SDA kumtunda mafani awiri mpaka asanu ndi atatu kutsika mawiri awiri, kapena mayendedwe.Njira iliyonse ya SCn/SDn kapena kuphatikiza kwa tchanelo kumatha kutsekedwa, kutengera zomwe zili mu kaundula wowongolera.Njira zotsika izi zitha kugwiritsidwa ntchito kuthetsa I2C akapolo athane ndi mikangano.Mwachitsanzo, ngati masensa asanu ndi atatu ofanana a kutentha kwa digito akufunika pakugwiritsa ntchito, sensor imodzi imatha kulumikizidwa panjira iliyonse: 0-7.
Dongosolo la master litha kukonzanso TCA9548A pakatha nthawi kapena kusachita bwino kwina potsimikizira kutsika kwa RESET.Momwemonso, kuyimitsanso mphamvu kumachotsa mayendedwe onse ndikuyambitsa I2Makina amtundu wa C/SMBus.Kutsimikizira kuti RESET kumapangitsa kukonzanso komweku ndikuyambitsanso kuchitika popanda kutsitsa gawolo.Izi zimathandiza kuchira ngati mmodzi wa downstreamI2Mabasi a C amakhala otsika kwambiri.
Zipata zodutsa zosinthira zimamangidwa kuti pini ya VCC igwiritsidwe ntchito kuchepetsa voteji yapamwamba kwambiri, yomwe imadutsa TCA9548A.Kuchepetsa pazipita voteji kumalola kugwiritsa ntchito ma voltages osiyanasiyana mabasi pa gulu lililonse, kotero kuti 1.8-V, 2.5-V kapena 3.3-V mbali akhoza kulankhula ndi 5-V mbali, popanda chitetezo zina.Zopinga zakunja zimakokera basi mpaka mulingo womwe ukufunidwa panjira iliyonse.Pini zonse za I/O ndizololera 5-V.
1. Kodi ogwira ntchito m'dipatimenti yanu ya R & D ndi ndani?Kodi ziyeneretso zanu ndi zotani?
-R & D Mtsogoleri: pangani dongosolo la nthawi yayitali la R & D ndikumvetsetsa momwe kafukufuku ndi chitukuko;Kuwongolera ndi kuyang'anira dipatimenti ya r&d kuti ikwaniritse njira zamakampani ndi mapulani apachaka a R&D;Kuwongolera kupita patsogolo kwa chitukuko cha mankhwala ndikusintha dongosolo;Khazikitsani gulu labwino kwambiri la kafukufuku wazinthu ndi chitukuko, kufufuza ndi kuphunzitsa ogwira ntchito zaukadaulo.
Woyang'anira R & D: pangani mankhwala atsopano a R & D ndikuwonetsa kuthekera kwa dongosolo;Kuyang'anira ndi kuyang'anira momwe ntchito ya R&d ikuyendera;Fufuzani zachitukuko chazinthu zatsopano ndikupereka mayankho ogwira mtima malinga ndi zomwe makasitomala amafuna m'magawo osiyanasiyana
Ogwira ntchito ndi R&d: sonkhanitsani ndikusankha zofunikira;Mapulogalamu apakompyuta;Kuyesa, kuyesa ndi kusanthula;Konzani zida ndi zida zoyeserera, zoyeserera ndi kusanthula;Lembani deta yoyezera, pangani mawerengedwe ndikukonzekera ma chart;Chitani kafukufuku wamawerengero
2. Kodi lingaliro lanu la kafukufuku ndi chitukuko ndi chiyani?
- Lingaliro lazinthu ndi kusankha kwazinthu ndikuwunika tanthauzo lazinthu ndi kapangidwe ka pulani ya projekiti ndi kuyezetsa kwachitukuko ndikutsimikizira kukhazikitsidwa kwa msika
