IPortenta H7: konke odinga ukukwazi mayelana nale nkundla

IPortenta H7

Ku-Consumer Electronics Show eLas Vegas, kwethulwe ubuchwepheshe obukhulu bezobuchwepheshe. U-Arduino uphinde wasebenzisa leli thuba ukukhombisa ezinye zezikhali zakhe ezifihliwe azolisebenzisa. Futhi akuzange kungabonakali phakathi kwama-Smartphones, ama-TV ahlakaniphile, izimoto zikagesi, kanye namadivayisi we-IoT ezenzakalelayo. Intsha yabizwa IPortenta H7 futhi bekuyisikhungo sokunakwa kwabathandi bengxenyekazi edumile yentuthuko.

Kuyiqiniso ukuthi i-Arduino igxile kuze kube manje kwi imakethe yezemfundo nabenzi noma abathandi be-DIY. Ngisho namapuleti ayo amakwe i-Pro nawo angasetshenziswa kule ndawo yabathengi kumaphrojekthi athile. Yize kuliqiniso ukuthi kunamaphrojekthi athile obuchwepheshe asebenzise i-Arduino njengesisekelo ...

Kepha manje baqhubeka kancane nePortenta H7 futhi bayiklama ikakhulukazi nabasebenza ngengqondo. Labo bantu noma izinkampani ezifuna ukuthuthukisa amaphrojekthi wehardware ngokushesha nangokuqinile ukuze izicelo zezimboni.

Yini iPortenta H7?

Ibhodi Yezentuthuko IPortenta H7 ikhazimulisa igama layo futhi ihlanganise ezinye izinsimbi ezinamandla. Ngamandla angenawaya akhelwe ngaphakathi (asevele akhiwe ngaphakathi), amandla wokuqalisa imibhalo ebhalwe ngePython neJavaScript, futhi alayishwa ngezinsizakusebenza. Konke ngentengo ye- 89.90 €. Ukuba musha sha usungavele uyi-ode, ngoba i-oda langaphambilini kuwebhusayithi esemthethweni ye-Arduino.

Yize kuyintengo engabiza ngandlela thile kubenzi nomkhakha wezemfundo, lokhu akubekelwa eceleni ekusetshenzisweni kwayo. Ngaphezu, kukhona okunye okunye amabhodi entuthuko nama-SBC anezintengo ezifanayo noma eziphakeme kakhulu.

Yebo, izimfanelo kusuka ePortenta H7 yenza leli bhodi libe kude kakhulu nama-Arduino wendabuko. Futhi ukuthi umkhakha ebhekiswe kuwo uyayifuna, ngoba amanye ama-chips angama-8-bit MCU ebengeke anele, futhi nemikhawulo ethile yamanye amabhodi omndeni ayengeke enele. Kudingeka ama-microcontroller anamandla athe xaxa embonini.

Esinye isici esikwenza kuthakazelise kakhulu ukuthi kungagcini ngokuhlelwa ngezilimi ezisezingeni eliphakeme njengalezo ezibalulwe ngenhla nemisebenzi yesikhathi sangempela, futhi iyasekela I-AI (intelligence yokufakelwa) eneTensorFlow, ngenkathi igcina ukusebenza kwe-latency ephansi ngenxa yehadiwe hardware yayo. Isibonelo, kungenzeka ukusebenzisa ikhodi ehlanganiselwe i-Arduino eceleni kwe-MicroPython futhi ugcine izinhlamvu ekuxhumaneni zodwa.

Sebenzisa ifomethi yePortenta Carrier Board ukuguqula i-H7 ibe yi- eNUC, okusho ukuthi, i-minicomputer enamandla engenza konke okwenzayo manje nge-Arduino nokuningi, njengokusebenzisa ama-algorithms wokubuka kwamakhompiyutha we-othomathikhi wendiza, ngenkathi ugcina ukulawula kwezinga eliphansi lemoto, ama-rudders, njll.

Ngamafuphi, ipuleti eliklanyelwe imboni noma njengezinto zaselebhu, amandla okusebenzisa umbono wekhompyutha, Ama-PLC, izindawo ezilungele ukusetshenziswa zomkhakha, ukulawulwa kwamarobhothi, amadivayisi wohlelo olubucayi, isivinini sokuqala esikhulu (ms).

2 cores ngokufana

I-Portenta H7 chip

Iprosesa emaphakathi yePotenta H7 iyi-dual-core I-STM32H747 kusuka ku-STMicroelectronics. Amashipsi aklanywe yiFrance avela emndenini we-STM-32 ohlanganisa ama-microcontroller angama-32-bit asuselwa ku-ARM ngaphakathi kufile. Kulokhu, ama-cores wokucubungula akhethiwe yi-Cortex M7 esebenza ku-480Mhz kanye neCortex M4 egijima ku-240Mhz.

Lezi zinhlamvu ezimbili zikhona ukukhishwa ngomshini obizwa nge-Remote Procedure Call ovumela izingcingo zomsebenzi ezingenamthungo kwenye iprosesa. Bobabili abaprosesa babelana ngemingcele futhi bangaqalisa:

  • Imidwebo ye-Arduino IDE njengoba nje elinye ibhodi le-Arduino belingakwenza. Izokwenza ku-ARM Mbed OS. Lolu uhlelo lokusebenza olushumekiwe lwale nkundla olusetshenziswa kumadivayisi we-IoT aneCortex-M.
  • Ungagijima futhi izinhlelo zokusebenza zomdabu yeMbed.
  • Ikhodi I-MicroPython neJavaScript ngomtoliki walezi zilimi ezihumushiwe.
  • Y I-TensorFlow Lite.

I-accelerator yezithombe

Enye yezinto ezifakiwe ku-Portenta H7, futhi enye yezinto ezimangalisa kakhulu, kungenzeka xhuma ibhodi ngesiqapha sangaphandle, sengathi ikhompyutha. Ngale ndlela, ikuvumela ukuthi udale ikhompiyutha yakho eshumekiwe enikezelwe nge-interface yayo yomsebenzisi.

Futhi ukuze lokho kwenzeke a I-GPU on-chip ngaphakathi kwe-STM32H747. Kulokhu, yi-Chrom-ART Accelertor, enama-encoder ayo nama-decoder e-JPEG.

Ukuphina

Iphinikhodi ye-Portenta H7

Inenqwaba yamaphini onawo wokuhlela nokusebenzisela amaphrojekthi akho. IPortenta H7 inayo Amaphini we-80 ukuxhumana okuphezulu kakhulu ebhodini. Lokho kunikeza ibhodi ukonakala okuhle nokuguquguquka okukhulu ngokuya ngezinhlelo zokusebenza kanye nokuvuselelwa okungenzeka okudingayo. Zizohambisana neziningi ze- izakhi ze-elekthronikhi kubonwe kule bhulogi nokuningi.

Conectividad

IPortenta H7 motherboard ifaka nokuxhuma I-WiFi ne-Bluetooth, ukuze ikwazi ukuyixhuma kumanethiwekhi ukusebenzisana nezinye izinto. Ngakho-ke, ngeke udinge amanye amamojula anjenge amanye amabhodi e-Arduino. Vele, futhi isekela ezinye izixhumi zokuxhumana ezifana ne-UART, i-SPI, i-Ethernet, i-I2C, ukuxhumana okuningiliziwe nge-USB-C (i-Display Port yokuqapha, ukulethwa kwamandla kumadivayisi we-OTG, ...), njll.

Imininingwane eminingi yehadiwe
