Chithunzi cha CC2520
CC2520 ndi m'badwo wachiwiri wa TI ZigBee®/ IEEE 802.15.4 RF transceiver ya 2.4 GHz yopanda chilolezo ya ISM band.Chip ichi chimathandizira ntchito zamagawo a mafakitale popereka kusankha kwanthawi zonse / kukhalapo, bajeti yabwino yolumikizirana, kugwira ntchito mpaka 125 ° C ndi kutsika kwamagetsi.
Kuphatikiza apo, CC2520 imapereka chithandizo chokulirapo cha Hardware pakugwiritsa ntchito chimango, kusungitsa deta, kutumiza mwachangu, kusungitsa deta, kutsimikizika kwa data, kuwunika komveka bwino kwa njira, chizindikiritso chaubwino wamalumikizidwe ndi chidziwitso chanthawi yake.Zinthu izi zimachepetsa katundu pa woyang'anira alendo.
M'dongosolo lanthawi zonse, CC2520 idzagwiritsidwa ntchito limodzi ndi microcontroller ndi zina zowonjezera zochepa.
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
