Tsanangudzo yeTCA9555
Iyi 16-bit I/O expander ye mitsara miviri bidirectional bhazi(I2C) yakagadzirirwa 1.65-V kusvika 5.5-V VCCoperation.Inopa zvakajairika-chinangwa kure I / O kuwedzera kune mazhinji microcontroller mhuri kuburikidza neI2C interface.
Iyo TCA9555 ine maviri 8-bit Configuration (yekuisa kana yekubuda sarudzo), Input Port,Output Port, uye Polarity Inversion (inoshanda yakakwirira kana inoshanda yakaderera mashandiro) marejista.Pasimba pa, iyo I/Os inogadziriswa seyekupinza.Iyo sisitimu tenzi inogona kugonesa iyo I / Os senge yekupinza kana maoutputs nekunyorera kune I/O mabhiti ekumisikidza.Iyo data yekuisa yega yega kana kubuda inochengetwa mune inoenderana Input kana Output register.Iyo polarity yeInput Port register inogona kutenderedzwa nePolarity Inversion register.
Iyo TCA9555 yakafanana neTCA9535, kunze kwekuisirwa mukatiI/O yekudhonza-up resistor, iyo inokwevera iyo I/O kune yakasarudzika yakakwira kana yakagadziridzwa seyekupinza uye isina kudhindwa.
Matatu mapini ehardware (A0, A1, uye A2) anoshandiswa kuronga iyoI2C kero, iyo inobvumira anosvika masere eTCA9555 zvishandiso kugovera imwecheteI2C bhazi kana SMBus.Iyo yakatarwa I2C kero yeTCA9555 yakafanana nePCF8575, PCF8575C, uyePCF8574, ichibvumira anosvika masere emidziyo iyi mune chero musanganiswa kugovera imwechete I2C bhazi kana SMBus.
1. Ndivanaani vashandi mudhipatimendi rako reR & D?Ndezvipi zvidzidzo zvako?
-R & D Mutungamiriri: gadzira chirongwa chekambani chenguva refu R & D uye ubate gwara rekutsvaga nekusimudzira;Tungamira uye tarisa r&d dhipatimendi kuti iite kambani r&d zano uye yegore R&D chirongwa;Dzora kufambira mberi kwekugadzirwa kwechigadzirwa uye gadzirisa chirongwa;Gadzira yakanakisa chigadzirwa chekutsvagisa uye timu yekusimudzira, yekuongorora uye yekudzidziswa ine chekuita nehunyanzvi vashandi.
R & D Maneja: gadzira chigadzirwa chitsva R & D kuronga uye kuratidza kugona kwechirongwa;Tarisa uye gadzirisa kufambira mberi uye kunaka kwer&d basa;Tsvagurudza kugadzirwa kwechigadzirwa chitsva uye kurudzira mhinduro dzinoshanda zvinoenderana nezvinodiwa nevatengi munzvimbo dzakasiyana
Vashandi veR&d: unganidza uye gadzirisa data rakakosha;Computer programming;Kuita zviedzo, bvunzo uye ongororo;Gadzirira zvinhu uye zvishandiso zvekuyedza, bvunzo uye ongororo;Rekodha data yekuyera, ita kuverenga uye gadzira machati;Ita ongororo dzenhamba
2. Ndeipi yako chigadzirwa tsvakurudzo uye budiriro pfungwa?
-Kufunga kwechigadzirwa uye sarudzo yechigadzirwa pfungwa uye yekuongorora tsanangudzo yechigadzirwa uye dhizaini dhizaini uye kusimudzira chigadzirwa kuyedzwa uye kusimbiswa kwekutanga kumusika.
