Chithunzi cha TCA9555
Chowonjezera ichi cha 16-bit I/O cha basi ya mizere iwiri yolowera pawiri (I2C) chapangidwira 1.65-V mpaka 5.5-V VCCoperation.Imapereka kukulitsa kwakutali kwa I/O kwa mabanja ambiri okhala ndi ma microcontroller kudzera pa I2C.
TCA9555 ili ndi ma 8-bit Configuration (zolowetsa kapena zotuluka), Port Input Port, Output Port, and Polarity Inversion (yogwira ntchito yapamwamba kapena yotsika).Pamagetsi, ma I/O amapangidwa ngati zolowetsa.Katswiri wamakina amatha kupangitsa ma I/O kukhala ngati zolowetsa kapena zotuluka polemba ku ma I/O makonda.Zomwe zalowetsedwa kapena zotulutsa zilizonse zimasungidwa mu regista ya Zolowetsa kapena Zotulutsa.Polarity ya regista ya Input Port ikhoza kusinthidwa ndi regista ya Polarity Inversion.
TCA9555 ndi yofanana ndi TCA9535, kupatulapo kuphatikizika kwa internalI/O kukoka mmwamba resistor, yomwe imakoka I/O kuti ikhale yokwera kwambiri ikakonzedwa ngati cholowetsa komanso chosasunthika.
Zikhomo zitatu za hardware (A0, A1, ndi A2) zimagwiritsidwa ntchito popanga adilesi yaI2C, yomwe imalola zida zisanu ndi zitatu za TCA9555 kugawana basi yaI2C kapena SMBus.Adilesi yokhazikika ya I2C ya TCA9555 ndi yofanana ndi PCF8575, PCF8575C, ndiPCF8574, kulola zida zisanu ndi zitatu izi kuphatikiza kulikonse kugawana basi ya I2C kapena SMBus.
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
