Zithunzi za TMS320LF2407A
Zida za TMS320LF240xA ndi TMS320LC240xA, mamembala atsopano a TMS320C24x™;kupanga owongolera ma digito a digito (DSP), ndi gawo la TMS320C2000™;nsanja ya fixed-point DSPs.Zida za 240xA zimapereka TMS320™ yowongoleredwa;Mapangidwe a DSP a C2xx core CPU otsika mtengo, otsika mphamvu, komanso ochita bwino kwambiri pokonza.Zotumphukira zingapo zapamwamba, zokometsedwa pamagetsi a digito ndi ntchito zowongolera zoyenda, zaphatikizidwa kuti zipereke chowongolera chenicheni cha single-chip DSP.Pomwe khodi-yogwirizana ndi C24x™ yomwe ilipo;Zipangizo zowongolera za DSP, 240xA imapereka magwiridwe antchito ochulukira (40 MIP) komanso mulingo wapamwamba wophatikizira zotumphukira.Onani gawo la Chidule cha Chipangizo cha TMS320x240xA kuti mudziwe zambiri za chipangizocho.
M'badwo wa 240xA umapereka kukula kwa kukumbukira ndi zotumphukira zosiyanasiyana zomwe zimapangidwira kuti zikwaniritse mtengo / magwiridwe antchito omwe amafunidwa ndi mapulogalamu osiyanasiyana.Zipangizo zong'anima za mawu ofikira 32K zimapereka njira yotsika mtengo yosinthira kupanga voliyumu.Zipangizo za 240xA zimakhala ndi mawu achinsinsi a "code security" zomwe zimakhala zothandiza popewa kubwereza mosaloledwa kwa ma code eni eni omwe amasungidwa pa-chip Flash/ROM.Dziwani kuti zida za Flash-based zili ndi 256-mawu oyambira ROM kuti athandizire kukonza mapulogalamu.Banja la 240xA limaphatikizanso zida za ROM zomwe zimagwirizana kwathunthu ndi anzawo a Flash.
Zida zonse za 240xA zimapereka gawo limodzi loyang'anira zochitika zomwe zakonzedwa kuti ziwongolere magalimoto a digito ndikugwiritsa ntchito kusintha mphamvu.Kuthekera kwa gawoli kumaphatikizapo m'badwo wa PWM wapakati- ndi/kapena m'mphepete, bandeji yosinthika kuti mupewe zolakwika, komanso kutembenuka kwa analogi kupita ku digito.Zipangizo zomwe zimakhala ndi oyang'anira zochitika zapawiri zimathandizira ma mota angapo ndi/kapena zosinthira ndi chowongolera chimodzi cha 240xA DSP.Sankhani ma EV mapini aperekedwa ndi "input-qualifier" yozungulira, yomwe imachepetsa kuyambika kwa mapini mosadziwa ndi glitches.
Kutembenuza kwapamwamba kwambiri, 10-bit analog-to-digital converter (ADC) ili ndi nthawi yochepa yotembenuza 375 ns ndipo imapereka mpaka 16 njira za analogi.Kuthekera kwa autosequencing kwa ADC kumalola kutembenuka kwakukulu kwa 16 kuti kuchitike mu gawo limodzi losinthika popanda mutu uliwonse wa CPU.
Ma serial communications interface (SCI) amaphatikizidwa pazida zonse kuti apereke kulumikizana kwa asynchronous ku zida zina mudongosolo.Pamakina omwe amafunikira njira zowonjezera zolumikizirana, 2407A, 2406A, 2404A, ndi 2403A imapereka mawonekedwe a 16-bit synchronous serial peripheral interface (SPI).2407A, 2406A, ndi 2403A imapereka module yolumikizirana ya controller area (CAN) yomwe imakwaniritsa 2.0B.Kuti muwonjezere kusinthasintha kwa chipangizocho, zikhomo zogwirira ntchito zimathanso kusinthidwa ngati zolowetsa/zotulutsa (GPIOs).
Kuti muchepetse nthawi yachitukuko, kutsanzira kogwirizana ndi JTAG kwaphatikizidwa muzipangizo zonse.Izi zimapereka mphamvu zenizeni zenizeni zomwe siziyenera kusokoneza machitidwe owongolera digito.Zida zonse zopangira ma code kuchokera kwa opanga C kupita ku Code Composer Studio™;debugger imathandizira banja ili.Madivelopa ambiri a chipani chachitatu samangopereka zida zachitukuko za chipangizocho, komanso mawonekedwe adongosolo ndi chithandizo chachitukuko.
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
