Ibisobanuro kuri CC2520
CC2520 nigisekuru cya kabiri cya TI ZigBee® / IEEE 802.15.4 RF transceiver ya 2.4 GHz idafite ISM idafite uruhushya.Iyi chip ituma urwego rwinganda rushyirwaho mugutanga uburyo bugezweho bwo guhitamo / kubana, ingengo yimishinga ihuza, gukora kugeza kuri 125 ° C hamwe na voltage ikora.
Mubyongeyeho, CC2520 itanga infashanyo nini yibikoresho byo gutunganya ikadiri, kubika amakuru, guturika guturika, kubika amakuru, kwemeza amakuru, gusuzuma neza imiyoboro, guhuza ubuziranenge no kwerekana amakuru yigihe.Ibiranga kugabanya umutwaro kuri host hostler.
Muri sisitemu isanzwe, CC2520 izakoreshwa hamwe na microcontroller hamwe nibindi bikoresho byiyongera.
1. Ni bande bakozi mu ishami rya R & D?Ni ubuhe bushobozi bwawe?
-R & D Umuyobozi: gutegura gahunda yigihe kirekire yikigo no gusobanukirwa icyerekezo cyubushakashatsi niterambere;Kuyobora no kugenzura ishami rishyira mubikorwa ingamba za sosiyete na gahunda ya R&D yumwaka;Kugenzura iterambere ryibicuruzwa no guhindura gahunda;Shiraho ibicuruzwa byiza byubushakashatsi niterambere, kugenzura no guhugura abakozi ba tekiniki bijyanye.
Umuyobozi wa R & D: kora ibicuruzwa bishya R & D hanyuma werekane ko bishoboka gahunda;Kugenzura no gucunga iterambere nubuziranenge bwakazi;Kora ubushakashatsi ku bicuruzwa bishya kandi utange ibisubizo bifatika ukurikije ibyo umukiriya asabwa mubice bitandukanye
Abakozi & gukusanya: gukusanya no gutondekanya amakuru yingenzi;Porogaramu ya mudasobwa;Gukora ubushakashatsi, ibizamini nisesengura;Tegura ibikoresho nibikoresho byo kugerageza, kugerageza no gusesengura;Andika amakuru yo gupima, gukora ibarwa no gutegura imbonerahamwe;Kora ubushakashatsi bwibarurishamibare
2. Niki gitekerezo cyawe cyo gukora ubushakashatsi nibitekerezo byiterambere?
- Igitekerezo cyibicuruzwa no guhitamo ibicuruzwa nibisobanuro byerekana ibicuruzwa nibishushanyo mbonera byumushinga no kugerageza ibicuruzwa bitezimbere no kwemeza isoko
