Portenta H7: nā mea āpau āu e ʻike ai e pili ana i kēia anuu

Mana H7

Ma ka Consumer Electronics Show ma Las Vegas, ua hōʻike ʻia nā hana ʻenehana nui. Ua lawe ʻo Arduino i ka manawa kūpono e hōʻike i kekahi o kāna mau mea huna huna e hoʻoili ʻia. A ʻaʻole ia i ʻike maka ʻole ʻia ma waena o nā kelepona, nā kīwī akamai, nā kaʻa uila, a me nā hāmeʻa home IoT home. Kāhea ʻia ka mea hou Mana H7 aʻo ia ke kikowaena o ka nānā no nā mea aloha i ka paepae hoʻomohala kaulana.

He ʻoiaʻiʻo ua kālele nui ʻo Arduino i ka mākeke aʻo a no nā mea hana a i ʻole he mau ipo DIY. ʻOiai ʻo kāna mau pā i kaha ʻia Pro hiki ke hoʻohana pū ʻia i kēia kaiapuni mea kūʻai no kekahi mau papahana. ʻOiai he ʻoiaʻiʻo aia kekahi mau papahana ʻoihana i hoʻohana iā Arduino ma ke ʻano he kumu ...

Akā i kēia manawa ua hele iki lākou me ka Portenta H7 a hoʻolālā lākou ia me nā poʻe loea i ka manaʻo. ʻO kēlā mau poʻe a i ʻole nā ​​hui e makemake e hoʻomohala wikiwiki i nā papahana lako nā noi hana.

He aha ka Portenta H7?

Papa hoʻomohala Mana H7 hoʻolaha ʻia kona inoa a hoʻohui i kekahi o nā lako pono ikaika. Me nā pono uila ʻole i kūkulu ʻia (kūkulu ʻia i loko), nā hiki ke holo i nā script i kākau ʻia ma Python a me JavaScript, a hoʻouka ʻia me nā kumuwaiwai. No ke kumu kūʻai o 89.90 €. ʻOiai he mea hou loa hiki iā ʻoe ke ʻoka iā ia, ʻoiai aia ia ma ke kaʻina mua ma ka pūnaewele official Arduino.

ʻOiai he kumu kūʻai i hiki ke uku ʻia no nā mea hana a me ka ʻāpana aʻo, ʻaʻole i kāpae ʻia kēia mai kāna hoʻohana ʻana. He aha hou aʻe, aia kekahi papa hoʻomohala a me SBC i loaʻa nā kumukūʻai like a ʻoi paha ke kiʻekiʻe.

Ae, aia. nā ʻano mai Portenta H7 e hana i kēia papa i kahi mamao loa mai nā Arduinos kuʻuna. A ʻo ia ka ʻāpana i kuhikuhi ʻia iā ia e koi iā ia, ʻoiai ʻaʻole lawa nā ʻāpana MCU 8-bit, ʻaʻole hoʻi i kekahi mau palena o nā papa ʻē aʻe o ka ʻohana. Pono kahi microcontrollers ʻoi aku ka mana i ka ʻoihana.

ʻO kekahi hiʻohiʻona e hoihoi loa i ka hoihoi ʻana ʻaʻole hiki ke hoʻolālā ʻia me nā ʻōlelo kiʻekiʻe e like me nā mea i ʻōlelo ʻia ma luna a me nā hana manawa maoli, kākoʻo pū ia AI (ʻike naʻau) me TensorFlow, ʻoiai e mālama ana i ka operency latency haʻahaʻa haʻahaʻa i kāna lako pono i hoʻonui ʻia. ʻO kahi laʻana, hiki ke holo i ke code i hōʻuluʻulu ʻia no Arduino ma kahi o MicroPython a mālama i nā kernels i ke kamaʻilio pū ʻana me kekahi.

E hoʻohana i kahi mana o ka Papa lawe hānai Portenta e hoʻololi i ka H7 i a eNUC, ʻo ia hoʻi, kahi minicomputer ikaika i hiki ke hana i nā mea āpau āu e hana ai i kēia manawa me Arduino a me nā mea hou aku, e like me ka hoʻohana ʻana i nā algorithms ʻike kamepiula no kahi ʻano lele lele, ʻoiai e mālama ana i ka kaohi haʻahaʻa o ka motika, nā huila, a pēlā aku.

I ka pōkole, kahi papa i hoʻolālā ʻia no ka ʻoihana a i ʻole he mea hana keʻena hoʻokolohua, ka hiki ke hoʻohana hihio kamepiula, PLCs, mākaukau ʻoihana hoʻohana mea hoʻohana, ka lopako kaohi, nā polokalamu noi loiloi, wikiwiki wikiwiki kiʻekiʻe (ms).

Nā ʻāpana 2 i ka like

Pāʻālua Portenta H7

ʻO ke kikowaena kikowaena o ka Potenta H7 kahi kumu nui STM32H747 mai STMicroelectronics. Nā ʻāpana i hoʻolālā ʻia e Palani mai ka ʻohana STM-32 i pūʻolo i nā microcontrollers ma muli o 32-bit ARM ma loko o ka make. I kēia hihia, ʻo nā ʻoka hana i koho ʻia ʻo Cortex M7 e holo nei ma 480Mhz a me Cortex M4 e holo nei ma 240Mhz.

ʻO kēia mau ʻelua ʻelua hoʻokuʻi ma o kahi ʻano hana i kapa ʻia ʻo Ke Kaʻina Hana Kumu Mamao e hiki ai ke kāhea i nā hana seamless i ka mea hana ʻē aʻe. Māhele nā ​​mea hana ʻelua i nā peripherals a hiki ke holo:

  • Nā sketch o Arduino IDE e like me kahi papa Arduino ʻē aʻe. E hana ia ma ARM Mbed OS. ʻO kēia kahi ʻōnaehana i hoʻokomo ʻia no kēia anuu i hoʻohana ʻia i nā hāmeʻa IoT me Cortex-M.
  • Hiki iā ʻoe ke holo pū kekahi polokalamu maoli no Mbed.
  • Kuleana MicroPython a me JavaScript ma o ka mea unuhi'ōlelo o kēia mau ʻōlelo i unuhi ʻia.
  • Y LensorFlow Lite.

Hoʻoikaika kiʻi

ʻO kekahi o nā hiʻohiʻona i komo pū ʻia ma Portenta H7, a ʻo kekahi o nā mea pūʻiwa pū kekahi, ʻo ia ka hiki hoʻohui i ka papa me kahi nānā waho, me he mea lā he kamepiula ia. I kēia ala, ʻae ʻo ia iā ʻoe e hana i kāu kamepiula i hoʻolaʻa ʻia ponoʻī me kāna pono hoʻohana ponoʻī.

A no ka mea hiki ke hiki a GPU ma-ʻāpana loko o ka STM32H747. I kēia hihia he Chrom-ART Accelertor ia, me nā encoders ponoʻī a me nā decoder no JPEG.

ʻO Portenta H7 pinout

Loaʻa iā ia kahi helu nui o nā pine i kou makemake e polokalamu a hoʻohana no kāu mau papahana. ʻO Portenta H7 kahi 80 pines pilina paʻa loa ma ka papa. Hāʻawi kēlā i ka papa i ka scalability maikaʻi a me ka loli nui i ka ʻōlelo o nā noi a me nā hōʻano hou e pono ai. E kūlike lākou me nā mea he nui o mau mea uila ʻike ʻia ma kēia blog a me nā mea hou aʻe.

ʻO Conectividad

Hoʻokomo pū ka motherboard ʻo Portenta H7 i ka pilina WiFi a me Bluetooth, hiki ke hoʻohui iā ia i nā pūnaewele e launa pū me nā mea ʻē aʻe. No laila, ʻaʻole pono ʻoe i nā modula hou e like me nā papa Arduino ʻē aʻe. ʻOiaʻiʻo, kākoʻo nō ia i nā ʻaoʻao ʻē aʻe e like me UART, SPI, Ethernet, I2C, hoʻohui multipurpose ma o ka USB-C (Hōʻike Port no ka monitor, ka lawe mana no nā polokalamu OTG, ...), etc.

Nā kikoʻī lako paʻa hou aku

Portenta H7 (ʻike pū ʻia e ka inoa inoa H7-15EUNWAD) hele mai me kēia:

Nā pepa palapala a me nā palapala hou

Inā makemake ʻoe i nā kikoʻī e pili ana i ka Portenta H7 a me kāna mau ʻāpana, hiki iā ʻoe ke hoʻoiho i kēia palapala a palapala paha hāʻawi


Hoʻopili ka ʻike o ka ʻatikala i kā mākou kumumanaʻo o ka hoʻoponopono hoʻoponopono. E hōʻike i kahi kaomi hemahema ʻaneʻi.
