Tsanangudzo yeCC2520
Iyo CC2520 ichizvarwa chechipiri cheTI ZigBee®/ IEEE 802.15.4 RF transceiver ye2.4 GHz isina rezenisi ISM bhendi.Iyi chip inogonesa maindasitiri egiredhi application nekupa mamiriro-e-the-art selectivity/co-existivity, yakanakisa link bhajeti, kushanda kusvika ku125 ° C uye yakaderera voltage kushanda.
Uye zvakare, iyo CC2520 inopa yakawedzera tsigiro yehardware yekubata furemu, data buffering, kuputika kutumira, encryption yedata, kusimbiswa kwedata, kujekesa chiteshi chekuongorora, kubatanidza mhando yechiratidzo uye furemu ruzivo rwenguva.Aya maficha anoderedza mutoro pamubati wemugadziri.
Mune yakajairwa sisitimu, iyo CC2520 ichashandiswa pamwe chete neiyo microcontroller uye mashoma ekuwedzera passive zvikamu.
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.
