I-Arduino PORTENTA H7 ABX00042 ibhodi lokuthuthukisa i-STM32H747 i-dual-core WIFI Bluetooth

Ukuxhumana kwe-Interboard

I-Portenta H7 onboard wireless module ivumela ukuphathwa kanyekanye kokuxhumana kwe-WiFi ne-Bluetooth, i-interface ye-WiFi ingaxhunywa kanye njengendawo yokungena, indawo yokusebenza noma imodi ekabili, isixhumi esibonakalayo se-WiFi singasetshenzwa njengendawo yokungena, indawo yokusebenza noma imodi ekabili kanyekanye AP/ I-STA, futhi ingakwazi ukuphatha amanani okudlulisa afika ku-65MbPS.Uhlu lwezindawo zokusebenzelana ezinezintambo ezihlukene, njenge-UART, SPI, Ethernet noma 12C, nazo zingadalulwa ngezixhumi ezithile zesitayela se-MKR noma isixhumi esisha se-Arduino Industrial 80Pin.

Isibonisi somkhiqizo

I-Portenta H7 isebenzisa kokubili ikhodi ethuthukisiwe nemisebenzi yesikhathi sangempela.Idizayini ihlanganisa amaphrosesa amabili angakwazi ukwenza imisebenzi ngokuhambisana.Ungenza ikhodi ehlanganiswe ne-Arduino nge-Micro Python futhi wenze ama-cores amabili axhumane.Ukusebenza kwe-Portenta kukabili, ingasebenza njenganoma iyiphi enye ibhodi ye-microcontroller eshumekiwe, noma ingasebenza njengephrosesa eyinhloko yekhompyutha eshumekiwe.Sebenzisa ibhodi le-Portenta ukuze uguqule i-H7 ibe ikhompuyutha ye-ENUC futhi uveze zonke izixhumanisi ezibonakalayo ze-H7.I-Portenta ikwenza kube lula ukusebenzisa izinqubo ezidalwe kusetshenziswa i-TensorFlow Lite, lapho ungaba neyodwa yama-cores ehlanganisa ngokuguqukayo ama-algorithms okubona kwekhompyutha kuyilapho enye yenza imisebenzi yezinga eliphansi, njengokulawula amamotho noma ukusebenza njengesixhumi esibonakalayo somsebenzisi.Sebenzisa i-Portenta uma ukusebenza kubalulekile.Kwezinye izimo esingacabanga ngazo: imishini yezimboni esezingeni eliphezulu, okokusebenza kwelabhorethri, izilawuli ezinengqondo ezihlelekayo zekhompiyutha, izixhumanisi zomsebenzisi ezilungele imboni, izilawuli zamarobhothi, okokusebenza okubalulekile okubalulekile, amakhompuyutha akhethekile azinikele, ikhompyutha yokuqalisa ngesivinini esikhulu (ama-milliseconds) .

Ama-cores amabili afanayo:

Iprosesa eyinhloko ye-Portenta H7 yi-dual-core STM32H747, kuhlanganise ne-CortexM7 egijima ku-480 MHz kanye ne-CortexM4 egijima ku-240 MHz.Ama-cores amabili axhumana ngomshini wokushaya ucingo ovumela izingcingo ezingenamthungo ukuthi zisebenze kwenye iphrosesa.Womabili amaphrosesa abelana ngawo wonke ama-hardware aku-chip futhi angasebenzisa: Imidwebo ye-Arduino phezu kwe-ArmMbed OS, izinhlelo zokusebenza zomdabu ze-MbedTM, i-MicroPython/JavaScript ngokusebenzisa umhumushi, i-TensorFlowLite.

I-Graphics Accelerator:

I-Portenta H7 ingaphinda ixhume kuzibonisi zangaphandle ukuze wakhe ikhompyutha yakho eshunyekiwe ezinikele ngokusebenzisa isixhumi esibonakalayo somsebenzisi.Lokhu kungenxa ye-GPU Chrom-ART Accelerator kuphrosesa ye-STM32H747.Ngokungeziwe ku-GPU, i-chip ihlanganisa isifaki khodi esizinikele se-JPEG kanye nesikhiphi khodi.

Izinga elisha lomsebenzi wephinikhodi:

Uchungechunge lwe-Portenta lungeza izixhumi ezimbili ezingu-80-high-density phansi ebhodini lokuthuthukisa.Vele uthuthukise ibhodi le-Portenta libe ibhodi lokuthuthukisa elifanelana nezidingo zakho ukuze uqinisekise ukulinganisa kwezinhlelo zokusebenza eziningi.

Uxhumano lwangaphakathi:

Amamojula angenantambo angaphakathi avumela ukuphathwa kanyekanye kokuxhumana kwe-WiFi ne-Bluetooth.I-interface ye-WiFi ingasetshenziswa njengendawo yokufinyelela, indawo yokusebenza, noma imodi ekabili kanye kanye i-AP/STA, futhi ingaphatha amazinga okudlulisa afika ku-65 Mbps.I-interface ye-Bluetooth isekela i-Bluetooth Classic ne-BLE.Uhlu lwezindawo zokusebenzelana ezinezintambo ezihlukene, njenge-UARTSPI, Ethernet noma 12C, zingadalulwa ngezinye izixhumi zesitayela se-MKR, noma ngesixhumi esisha se-Arduino Industrial 80-pin.
