Khokahano ea li-interboard
Portenta H7 onboard wireless module e lumella taolo e ts'oanang ea likhokahano tsa WiFi le Bluetooth, sehokelo sa WiFi se ka hokahanngoa ka nako e le 'ngoe e le sebaka sa phihlello, sebaka sa mosebetsi kapa mokhoa o habeli, sebopeho sa WiFi se ka sebetsoa joalo ka sebaka sa phihlello, seteishene sa mosebetsi kapa mekhoa e 'meli ka nako e le ngoe AP/ STA, 'me e khona ho sebetsana le litefiso tsa phetisetso ho fihla ho 65MbPS. Mefuta e fapaneng ea likhokahano tse nang le lithapo, joalo ka UART, SPI, Ethernet kapa 12C, le eona e ka pepesoa ka lihokelo tse ling tsa setaele sa MKR kapa sehokelo se secha sa Arduino Industrial 80Pin.
Pontšo ea lihlahisoa
Portenta H7 e sebetsa ka bobeli khoutu e tsoetseng pele le mesebetsi ea nako ea nnete. Moralo o kenyelletsa li-processor tse peli tse ka tsamaisang mesebetsi ka ho lekana. U ka sebelisa khoutu e hlophisitsoeng ea Arduino ka Micro Python 'me u etse hore li-cores tse peli li buisane. Ts'ebetso ea Portenta e habeli, e ka sebetsa joalo ka boto efe kapa efe e kentsoeng ea microcontroller, kapa e ka sebetsa joalo ka processor ea mantlha ea komporo e kentsoeng. Sebelisa boto ea Portenta ho fetolela H7 ho komporo ea ENUC le ho pepesa likhokahano tsohle tsa 'mele tsa H7. Portenta e etsa hore ho be bonolo ho tsamaisa lits'ebetso tse entsoeng ka TensorFlow Lite, moo o ka bang le e 'ngoe ea li-algorithms tsa pono ea khomphutha ha e 'ngoe e etsa ts'ebetso ea maemo a tlase, joalo ka ho laola li-motor kapa ho sebetsa joalo ka sebopeho sa mosebelisi. Sebelisa Portenta ha ts'ebetso e le bohlokoa. Maemong a mang re ka nahana ka: mechine e phahameng ea liindasteri, lisebelisoa tsa laboratori, li-computer vision programmable logic controllers, li-interfaces tse lokiselitsoeng ke indasteri, balaoli ba liroboto, lisebelisoa tsa bohlokoa tsa mosebetsi, lik'homphieutha tse tsitsitseng tse tsitsitseng, k'homphieutha ea ho qala ka lebelo le phahameng (milliseconds) .
Li-cores tse peli tse tšoanang:
Mochine o ka sehloohong oa Portenta H7 ke "dual-core STM32H747", ho kenyelletsa le CortexM7 e sebetsang ho 480 MHz le CortexM4 e sebetsang ho 240 MHz. Li-cores tse peli li buisana ka mochini oa mohala o hole o lumellang mehala e se nang moeli ho sebetsa ho processor e 'ngoe. Li-processor ka bobeli li arolelana lisebelisoa tsohle tsa on-chip mme li ka tsamaisa: Lits'oants'o tsa Arduino ka holim'a ArmMbed OS, lits'ebetso tsa matsoalloa tsa MbedTM, MicroPython/JavaScript ka mofetoleli, TensorFlowLite.
Graphics Accelerator:
Portenta H7 e ka boela ea hokela lits'oants'o tsa kantle ho iketsetsa komporo ea hau e kentsoeng ka sebopeho sa mosebelisi. Sena se leboha GPU Chrom-ART Accelerator ho processor ea STM32H747. Ntle le GPU, chip e kenyelletsa encoder ea JPEG e inehetseng le decoder.
Tekanyetso e ncha ea mosebetsi oa phini:
Letoto la Portenta le eketsa lihokelo tse peli tsa 80-pin tse phahameng ka tlase ho boto ea nts'etsopele. Ak'u ntlafatse boto ea Portenta ho boto ea nts'etsopele e lumellanang le litlhoko tsa hau ho netefatsa scalability bakeng sa mefuta e mengata ea likopo.
Khokahano ea kahare:
Li-module tsa waelese tsa onboard li lumella taolo e le 'ngoe ea likhokahano tsa WiFi le Bluetooth. Sehokelo sa WiFi se ka sebelisoa e le sebaka sa phihlello, seteishene sa mosebetsi, kapa mokhoa oa habeli ka nako e le 'ngoe AP/STA,' me se khona ho sebetsana le litefiso tsa phetisetso ho fihla ho 65 Mbps. Sehokelo sa Bluetooth se tšehetsa Bluetooth Classic le BLE. Mefuta e mengata e fapaneng ea likhokahano tse nang le lithapo, joalo ka UARTSPI, Ethernet kapa 12C, le eona e ka pepesoa ka lihokelo tse ling tsa setaele sa MKR, kapa ka sehokelo se secha sa Arduino Industrial 80-pin.
