Kumboniso wezoMbane zabaThengi eLas Vegas, ubuchwephesha obukhulu bezinto zobugcisa zanikezelwa. IArduino ikwasebenzisile ukubonisa ezinye zezixhobo zayo ezifihliweyo eziza kuzisebenzisa. Kwaye ayizange iqondwe phakathi kwee-smartphones, iiTV ezikrelekrele, izithuthi zombane, kunye nezixhobo zasekhaya ze-IoT. Ubutsha babizwa IPortenta H7 kwaye yayiliziko lokuqwalaselwa kwabathandi beqonga lophuhliso elidumileyo.
Kuyinyani ukuba iArduino ijolise ukuza kuthi ga ngoku Iimarike zemfundo kunye nabenzi okanye abathandi be-DIY. Nkqu iipleyiti zayo eziphawulwe iPro zingasetyenziselwa kule meko yabathengi kwiiprojekthi ezithile. Nangona kuyinyani ukuba kukho iiprojekthi zobuchwephesha ezisebenzise iArduino njengesiseko ...
Kodwa ngoku baya phambili ngakumbi ngePortenta H7 kwaye bayile ngokukodwa ngabaqeqeshiweyo engqondweni. Abo bantu okanye iinkampani ezifuna ukuphuhlisa iiprojekthi zehardware ngokukhawuleza nangokuqinileyo izicelo mveliso.
Yintoni iPortenta H7?
Ibhodi yophuhliso IPortenta H7 ibonakalisa igama layo kwaye idibanisa ezinye izixhobo ezinamandla. Ngamandla akhelwe ngaphandle kwamacingo (sele eyakhiwe ngaphakathi), amandla okuqhuba izikripthi ezibhalwe kwiPython nakwiJavaScript, kwaye zilayishwe ngezixhobo. Zonke ngexabiso le- 89.90 €. Ukuba mtsha kakhulu sele u-odola, kuba kulungelelaniswe kwangaphambili kwiwebhusayithi esemthethweni yeArduino.
Nangona lixabiso elinokubiza ixabiso elithile kubenzi nakwicandelo lezemfundo, oku akubekelwa ecaleni ekusebenziseni kwayo. Ngaphezu, kukho ezinye iibhodi zophuhliso nee-SBCs ezinamaxabiso afanayo okanye nangaphezulu.
Ewe, iimpawu ukusuka kwiPortenta H7 yenza ukuba le bhodi ikude lee kwiiArduino zemveli. Kwaye kukuba icandelo elijolise kulo liyayidinga, kuba iichips ze-8-bit ze-MCU azinakwanela, kwaye kungabikho mida kwezinye iibhodi zosapho. Ukulawulwa kwezinto ezincinci ezinamandla ngakumbi ziyafuneka kumzi mveliso.
Elinye inqaku elenza libe nomdla ngakumbi kukuba ayizukucwangciswa kuphela ngeelwimi ezikumgangatho ophezulu ezinje ngezo zikhankanywe apha ngasentla kunye nemisebenzi yexesha lokwenyani, ikwaxhasa I-AI (ubukrelekrele bokufakelwa) kunye neTensorFlow, Ngelixa kugcinwa ukusebenza kwe-latency ephantsi ngenxa yesixhobo sayo esenziwe kakuhle. Umzekelo, kunokwenzeka ukuba usebenzise ikhowudi edityanelwe iArduino ecaleni kweMicroPython kwaye ugcine iinkozo zinxibelelana nabanye.
Sebenzisa ifomathi yeBhodi yePortenta yokuguqula i-H7 ibe yi eNUCOko kukuthi, ikhompyutha encinci enamandla angenza yonke into oyenzayo ngoku ngeArduino kunye nokunye, njengokusebenzisa ii-algorithms zombono zekhompyuter zendlela yokubaleka ngokuzenzekelayo, ngelixa ugcina inqanaba elisezantsi lolawulo lwemoto, iiruders, njl.
Ngamafutshane, ipleyiti eyenzelwe ngokukodwa ishishini okanye njengelabhoratri, amandla okusebenzisa umbono wekhompyuter, Ii-PLCs, indawo ekulungeleyo ukujongana nomsebenzisi, ulawulo lweerobhothi, izixhobo zesicelo esibalulekileyo, isantya sokuqala (ms).
I-2 cores ngokudibeneyo
Iprosesa esembindini yePotenta H7 sisiseko esingumbini I-STM32H747 ukusuka kwi-STMicroelectronics. Iitshipsi eziyilelwe ngesiFrentshi ezivela kusapho lwe-STM-32 ezibopha i-32-bit ARM-based microcontroller ngaphakathi ekufeni. Kule meko, ii-cores ezikhethiweyo zokwenza i-Cortex M7 isebenza kwi-480Mhz kunye neCortex M4 ebaleka kwi-240Mhz.
Ezi cores zimbini zi ukukhutshwa ngokusebenzisa isixhobo esibizwa ngokuba yiNkqubo yokuFowunelwa kude ekuvumela ukuba umsebenzi ongafakwanga ufowunele kwenye iprosesa. Zombini iiprosesa zabelana ngemida kwaye zinokuqhuba:
- Imizobo yeArduino IDE kanye njengenye ibhodi yeArduino. Iya kuyenza kwi-ARM Mbed OS. Le yinkqubo yokusebenza efakwe kweli qonga elisetyenziswa kwizixhobo ze-IoT ezineCortex-M.
- Ungaqhuba ii -apps zemveli yeMbed.
- Ikhowudi MicroPython kunye neJavaScript kusetyenziswa itoliki yezi lwimi zitolikwe.
- Y I-TensorFlow Lite.
Isantya sokuzoba
Enye yeempawu ezibandakanyiweyo kwiPortenta H7, kwaye enye yezona zinto zimangalisa kakhulu, yinto enokwenzeka qhagamshela ibhodi kunye nokujonga kwangaphandle, ngokungathi yikhompyuter. Ngale ndlela, ikuvumela ukuba wenze ikhompyuter yakho ezinikezelweyo ebethelelwe kunye nomsebenzisi wayo.
Kwaye loo nto inokwenzeka I-GPU kwi-chip ngaphakathi kwe-STM32H747. Kule meko yiChrom-ART Accelertor, ineekhowudi zayo kunye neekhowudi zokwenza iJPEG.
Phina
Inenani elikhulu lezikhonkwane onokuzisebenzisa kwinkqubo kunye nokusetyenziselwa iiprojekthi zakho. IPortenta H7 inayo Iiplini ze80 uxinizelelo oluphezulu ebhodini. Oko kunika ibhodi imeko elungileyo kunye nokuguquguquka okukhulu malunga nezicelo kunye nohlaziyo olunokwenzeka oludingayo. Ziya kuhambelana noninzi lweefayile ze- izinto zombane kubonwe kule bhlog nangaphezulu.
Conectividad
Ibhodi yomama yePortenta H7 ikwabandakanya unxibelelwano I-WiFi kunye neBluetooth, ukuze ukwazi ukudibanisa neenethiwekhi ukuze zisebenzisane nezinye izinto. Ke ngoko, awudingi iimodyuli ezongezelelweyo ezinje nge ezinye iibhodi zeArduino. Ewe kunjalo, ikwaxhasa ezinye izinto ezinje nge-UART, i-SPI, i-Ethernet, i-I2C, unxibelelwano oluninzi nge-USB-C (iZibuko lokuBonisa iliso, ukuhanjiswa kwamandla kwezixhobo ze-OTG, ...), njl.
