Arduino PORTENTA H7 ABX00042 guddiga horumarinta STM32H747 dual-core WIFI Bluetooth

Isku xirka sabuuradaha

Qalabka wireless-ka ee Portenta H7 wuxuu u oggolaanayaa maaraynta isku mar ee WiFi iyo isku xirka Bluetooth-ka, interface-ka WiFi waxaa lagu xiri karaa isla mar ahaantaana meel laga galo, goob shaqo ama qaab laba-gees ah, interface-ka WiFi waxaa loo shaqeyn karaa sidii goob marin, goob shaqo ama laba qaab isku mar AP / STA, waxayna xamili kartaa xadiga xawilaadaha ilaa 65MbPS. Isku xirka fiilooyinka kala duwan, sida UART, SPI, Ethernet ama 12C, ayaa sidoo kale lagu soo bandhigi karaa isku xirayaasha qaabka MKR ama isku xiraha cusub ee Arduino Industrial 80Pin

Bandhiga alaabta

Portenta H7 waxay waddaa kood horumarsan iyo hawlaha wakhtiga-dhabta ah. Naqshadeynta waxaa ku jira laba processor-ka kuwaas oo si isbar-bar socda u wadi kara hawlaha. Waxaad ku fulin kartaa koodka la soo aruuriyay ee Arduino oo wata Micro Python oo waxaad yeelan kartaa labada geesood inay wada xiriiraan midba midka kale. Shaqada Portenta waa laba laab, waxay u shaqayn kartaa sida boodhka kale ee microcontroller-ka ah, ama waxay u shaqayn kartaa sida processor-ka ugu wayn ee kombayuutarka ku xidhan. Isticmaal boorsada Portenta si aad H7 ugu beddesho kombayuutarka ENUC oo aad u muujiso dhammaan is-dhexgallada jirka ee H7. Portenta waxay fududaynaysaa socodsiinta hababka la abuuray iyadoo la adeegsanayo TensorFlow Lite, halkaas oo aad ku yeelan karto mid ka mid ah xudunta si firfircoon u xisaabiya algorithms-ka aragga kumbuyuutarka halka kan kalena uu qabto hawlo heer hoose ah, sida xakamaynta matoorada ama u dhaqma sidii is-dhexgal isticmaale. Isticmaal Portenta marka waxqabadku muhiim yahay. Xaaladaha kale waxaan ka fikiri karnaa: mishiinada warshadaha ee dhamaadka-dhamaadka ah, qalabka shaybaadhka, kontaroolayaasha macquulka ah ee barnaamijka lagu baran karo aragga kombuyuutarka, isdhexgalka adeegsadaha u diyaarsan warshadaha, kontaroolayaasha robotic, qalabka muhiimka ah ee hawlgalka, kombiyuutarada go'an, kombuyuutarada bilawga xawaaraha sare leh (millise seconds) .

Laba geesood oo isbarbar socda:

Processor-bixiyaha ugu weyn ee Portenta H7 waa dual-core STM32H747, oo ay ku jiraan CortexM7 oo ku socda 480 MHz iyo CortexM4 oo ku socda 240 MHz. Labada xudun waxay ku wada xidhiidhaan hab durugsan habka wicitaanka kaas oo u ogolaanaya wicitaanada aan kala go'a lahayn inay ku shaqeeyaan processor-ka kale. Labada hawl-wadeenadu waxay wadaagaan dhammaan qalabka-chip hardware-ka waxayna ku socon karaan: Arduino sketches ee sare ee ArmMbed OS, codsiyada MbedTM ee asalka ah, MicroPython/JavaScript iyada oo loo marayo turjumaanka, TensorFlowLite.

Dardariyaha garaafyada:

Portenta H7 waxa kale oo ay ku xidhi kartaa bandhigyada dibadda si aad u dhisto kombuyuutar kuu gaar ah oo ku xidhan interface-ka isticmaalaha. Tani waxay mahad iska leedahay GPU Chrom-ART Accelerator ee processor-ka STM32H747. Marka lagu daro GPU-ga, chip-ku waxa ku jira cod-bixiye JPEG ah oo go'an.

Heer cusub oo loogu talagalay meelaynta biinanka:

Taxanaha Portenta wuxuu ku darayaa laba isku xirayaasha cufnaanta sare ee 80-pin xagga hoose ee guddiga horumarinta. Si fudud u cusboonaysii guddiga Portenta una samee guddi horumarineed oo ku habboon baahiyahaaga si aad u hubiso cabbirka codsiyada kala duwan.

Isku xirka dushiisa:

Qaybaha bilaa-waayirka ah ee dusheeda waxay ogolaadaan maaraynta isku mar ee WiFi iyo isku xirka Bluetooth. Interface-ka WiFi waxa loo isticmaali karaa meel laga galo, goob shaqo, ama laba hab oo isku mar ah AP/STA, waxana uu xamili karaa xawaaladaha wareejinta ilaa 65 Mbps. Isku xirka Bluetooth wuxuu taageeraa Bluetooth Classic iyo BLE. Isku xirka fiilooyinka kala duwan ee kala duwan, sida UARTSPI, Ethernet ama 12C, ayaa sidoo kale lagu soo bandhigi karaa isku xirayaasha qaabka MKR, ama iyada oo loo marayo lammaanaha cusub ee Arduino Industrial 80-pin.
