I-M5Stick CORE2 iyibhodi le-ESP32 elisekelwe ku-chip ye-ESP32-D0WDQ6-V3, equkethwe

Ukwakhiwa kwe-Hardware
Izingxenyekazi zekhompiyutha ze-CORE2: I-chip ye-ESP32-D0WDQ6-V3, isikrini se-TFT, i-LED Ekuhlaza, Inkinobho, isixhumi esibonakalayo se-GROVE, isixhumi esibonakalayo se-TypeC-to-USB, i-chip Management Power nebhethri.
I-ESP32-D0WDQ6-V3 I-ESP32 iyisistimu ekabili-core enama-CPU amabili e-Harvard Architecture Xtensa LX6. Yonke inkumbulo eshumekiwe, inkumbulo yangaphandle kanye nama-peripherals atholakala ebhasini ledatha kanye/noma ebhasini leziyalezo lalawa ma-CPU. Ngaphandle kokunye okuhlukile okuncane (bheka ngezansi), ukuklanywa kwekheli lama-CPU amabili kuyahambisana, okusho ukuthi basebenzisa amakheli afanayo ukuze bafinyelele. inkumbulo efanayo. Ama-peripheral amaningi ohlelweni angafinyelela inkumbulo eshumekiwe nge-DMA.

Isikrini se-TFT iyisikrini esinemibala engama-intshi angu-2 intshi eshayelwa i-ILI9342C nesixazululo esingu-320 x 240. I-Operating voltagUbubanzi be-e bungu-2.6~3.3V, izinga lokushisa elisebenzayo lingu-25~55°C.
I-chip yokuphatha amandla i-X-Powers's AXP192. Umthamo wokusebenzatagUbubanzi be-e bungu-2.9V~6.3V kanti amandla okushaja angu-1.4A.
I-CORE2 ihlomisa i-ESP32 ngakho konke okudingekayo ekuhleleni, yonke into edingekayo ekusebenzeni nasekuthuthukisweni

INCAZELO YOMSEBENZI

Lesi sahluko sichaza amamojula nemisebenzi ehlukahlukene ye-ESP32-D0WDQ6-V3.

CPU NEMEMORY 

I-Xtensa®single-/dual-core32-bitLX6microprocessor(s), upto600MIPS (200MIPSforESP32-S0WD/ESP32-U4WDH, 400 MIPS ye-ESP32-D2WD):

• 448 KB ROM
• 520 KB SRAM
• 16 KB SRAM ku-RTC
• I-QSPI isekela ama-flash/SRAM chips amaningi

INCAZELO YESITOREKO

I-Flash yangaphandle kanye ne-SRAM
I-ESP32 isekela i-flash ye-QSPI eminingi yangaphandle kanye nenkumbulo yokufinyelela engahleliwe (i-SRAM), enokubethela kwe-AES okusekelwe ku-hardware ukuvikela izinhlelo zomsebenzisi nedatha.

• I-ESP32 ifinyelela i-QSPI Flash yangaphandle kanye ne-SRAM ngokulondoloza isikhashana. Isikhala sekhodi ye-Flash yangaphandle esingafika ku-16 MB sifakwe kumephu ku-CPU, sisekela ukufinyelela okungu-8-bit, 16-bit no-32-bit, futhi singasebenzisa ikhodi.
• I-Flash yangaphandle efinyelela ku-8 MB kanye ne-SRAM efakwe kumephu yesikhala sedatha ye-CPU, isekela lokufinyelela kwe-8-bit, 16-bit kanye no-32-bit. I-Flash isekela ukusebenza kokufunda kuphela, i-SRAM isekela ukufunda nokubhala imisebenzi.

I-Crystal

I-crystal oscillator engu-2 MHz~60 MHz (40 MHz kuphela ekusebenzeni kwe-Wi-Fi/BT)

UKUPHATHWA KWE-RTC NOKUSETSHENZISWA KWAMANDLA ANGAPHANSI 

I-ESP32 isebenzisa amasu okuphatha amandla athuthukile ingase ishintshwe phakathi kwezindlela ezihlukene zokonga amandla. (Bheka iThebula 5).

• Imodi yokonga amandla
  • Imodi esebenzayo: I-RF chip iyasebenza. I-chip ingathola futhi idlulise isignali yomsindo.
  • Imodi yokulala yemodemu: I-CPU ingasebenza, iwashi lingase lilungiswe. I-Wi-Fi / i-Bluetooth baseband ne-RF
  • Imodi yokulala kancane: I-CPU imisiwe. I-RTC nenkumbulo kanye nama-peripherals ULP coprocessor operation. Noma yimuphi umcimbi wokuvuka (i-MAC, umsingathi, isibali sikhathi se-RTC noma ukuphazamiseka kwangaphandle) uzovusa i-chip.
  • Imodi yokulala okujulile: inkumbulo ye-RTC kuphela nama-peripherals asesimweni sokusebenza. Idatha yokuxhumana ye-Wi-Fi ne-Bluetooth egcinwe ku-RTC. I-ULP coprocessor ingasebenza.
  • Imodi ye-Hibernation: 8 MHz oscillator kanye ne-coprocessor ULP eyakhelwe ngaphakathi kukhutshaziwe. Imemori ye-RTC yokubuyisela ukunikezwa kwamandla ivaliwe. Isibali sikhathi sewashi se-RTC esisodwa kuphela esitholakala ewashini elinensayo kanye ne-RTC GPIO ethile emsebenzini. Iwashi le-RTC RTC noma isibali sikhathi singavuka kumodi ye-GPIO Hibernation.
• Imodi yokulala okujulile
  • imodi yokulala ehlobene: Imodi yokonga amandla ishintsha phakathi kwe-Active, Modem- sleeping, Imodi yokulala elula. I-CPU, i-Wi-Fi, i-Bluetooth, nesikhawu sesikhathi sokusetha kabusha umsakazo ukuze kuvuswe, ukuqinisekisa uxhumano lwe-Wi-Fi / Bluetooth.
  • Izindlela zokuqapha inzwa yamandla aphansi kakhulu: isistimu eyinhloko Imodi yokulala Okujulile, i-coprocessor ye-ULP ivulwa noma ivalwe ngezikhathi ezithile ukuze kukale idatha yenzwa. Inzwa ikala idatha, i-ULP coprocessor inquma ukuthi iluvuse yini uhlelo oluyinhloko.

UIFlow Ukuqala Okusheshayo

Ithuluzi elivuthayo

Qaphela: Ngemva kokufaka abasebenzisi be-MacOS, sicela ufake uhlelo lokusebenza kufolda yohlelo, njengoba kukhonjisiwe esithombeni esingezansi.

Ukushiswa kwe-Firmware

1. Chofoza kabili ukuze uvule ithuluzi lokushiswa kwe-Burner, khetha uhlobo lwedivayisi oluhambisanayo kumenyu engakwesokunxele, khetha inguqulo ye-firmware oyidingayo, bese uchofoza inkinobho yokudawuniloda.
2. Bese uxhuma idivayisi ye-M5 kukhompyutha ngentambo yohlobo C, khetha imbobo ye-COM ehambisanayo, izinga le-baud lingasebenzisa ukucushwa okuzenzakalelayo ku-M5Burner, ngaphezu kwalokho, ungakwazi futhi ukugcwalisa i-WIFI idivayisi ezoxhunywa kuyo ngesikhathi. ukushiswa kwe-firmware stage ulwazi. Ngemva kokucushwa, chofoza okuthi “Shisa” ukuze uqale ukushisa.
3. Lapho ugodo oluvuthayo lukhuthaza Ukushiswa Ngempumelelo, kusho ukuthi i-firmware ishisiwe.

Uma kuqala ukushisa noma uhlelo lwe-firmware lusebenza ngendlela engavamile, ungachofoza u-"Sula" ukuze usule imemori ye-flash. Esibuyekezweni esilandelayo se-firmware, asikho isidingo sokusula futhi, ngaphandle kwalokho ulwazi olugciniwe lwe-Wi-Fi luzosuswa futhi Ukhiye we-API uzovuselelwa.

Lungiselela i-WIFI

I-UIFlow inikeza kokubili okungaxhunyiwe ku-inthanethi futhi web inguqulo yomhleli. Lapho usebenzisa i- web inguqulo, sidinga ukumisa uxhumano WiFi kudivayisi. Okulandelayo kuchaza izindlela ezimbili zokulungisa uxhumano lwe-WiFi kudivayisi (Burn Configuration kanye ne-AP hotspot Configuration).

Shisa i-WiFi yokumisa (kuyancomeka)

I-UIFlow-1.5.4 nezinguqulo ezingenhla zingabhala imininingwane ye-WiFi ngokuqondile nge-M5Burner.

I-WiFi yokucushwa kwe-APhotspot

1. Cindezela futhi ubambe inkinobho yamandla kwesokunxele ukuze uvule umshini. Uma i-WiFi ingalungisiwe, isistimu izongena ngokuzenzakalelayo kumodi yokumisa inethiwekhi lapho ivulwa okokuqala. Ake sithi ufuna ukufaka kabusha imodi yokumisa inethiwekhi ngemva kokusebenzisa ezinye izinhlelo, ungabhekisela ekusebenzeni okungezansi. Ngemuva kokuthi Ilogo ye-UIFlow ivele ekuqaleni, chofoza ngokushesha inkinobho ethi Ikhaya (phakathi nendawo inkinobho ye-M5) ukuze ufake ikhasi lokumisa. Cindezela inkinobho kwesokudla se-fuselage ukuze ushintshele ku-Setting, bese ucindezela inkinobho ethi Ikhaya ukuze uqinisekise. Cindezela inkinobho engakwesokudla ukuze ushintshele kwi-WiFi Setting, cindezela inkinobho ethi Ikhaya ukuze uqinisekise, bese uqala ukumisa.
2. Ngemva kokuxhuma ngempumelelo kwi-hotspot ngeselula yakho, vula isiphequluli seselula ukuze uskene ikhodi ye-QR esikrinini noma finyelela ngokuqondile ku-192.168.4.1, faka ikhasi ukuze ugcwalise imininingwane yakho siqu ye-WIFI, bese uchofoza Lungiselela ukuze urekhode imininingwane yakho ye-WiFi. . Idivayisi izoqala kabusha ngokuzenzakalelayo ngemva kokulungisa ngempumelelo nokufaka imodi yokuhlela.

Qaphela: Izinhlamvu ezikhethekile "njengesikhala" azivunyelwe kulwazi olulungisiwe lwe-WiFi.

I-Network Programming Mode kanye ne-API KEY

Faka imodi yokuhlela yenethiwekhi

Imodi yokuhlela yenethiwekhi imodi yokudokha phakathi kwedivayisi ye-M5 ne-UIFlow web inkundla yokuhlela. Isikrini sizobonisa isimo samanje sokuxhumeka kwenethiwekhi kwedivayisi. Uma inkomba iluhlaza, kusho ukuthi ungathola ukusunduzwa kohlelo noma kunini. Ngaphansi kwesimo esimisiwe, ngemva kokulungiselelwa kokuqala okuyimpumelelo kwenethiwekhi ye-WiFi, idivayisi izoqala kabusha ngokuzenzakalelayo bese ifaka imodi yokuhlela yenethiwekhi. Uma ungazi ukuthi ungayifaka kanjani kabusha imodi yokuhlela ngemuva kokusebenzisa ezinye izinhlelo zokusebenza, ungabheka le misebenzi elandelayo.

iqala kabusha, cindezela inkinobho A kusixhumi esibonakalayo semenyu enkulu ukuze ukhethe imodi yokuhlela bese ulinda kuze kube yilapho inkomba elungile yenkomba yenethiwekhi ishintsha ibe luhlaza ekhasini lemodi yokuhlela. Finyelela ekhasini lokuhlela le-UIFlow ngokuvakashela i-flow.m5stack.com kusiphequluli sekhompyutha.

Ukumatanisa kwe-APKEY
I-API KEY iwubufakazi bokuxhumana bamadivayisi e-M5 uma usebenzisa i-UIFlow web ukuhlela. Ngokulungisa i-API KEY ehambisanayo ohlangothini lwe-UIFlow, uhlelo lungaphushelwa idivayisi ethile. Umsebenzisi udinga ukuvakashela i-flow.m5stack.com kukhompuyutha web isiphequluli sokufaka ikhasi lokuhlela le-UIFlow. Chofoza inkinobho yokusetha kubha yemenyu ekhoneni eliphezulu kwesokudla sekhasi, faka Ukhiye we-API kudivayisi ehambisanayo, khetha ihadiwe esetshenzisiwe, chofoza okuthi KULUNGILE ukuze ulondoloze futhi ulinde kuze kube yilapho icela ukuxhuma ngempumelelo.

 

I-HTTP

Qedela lezi zinyathelo ezingenhla, bese ungaqala ukuhlela nge-UIFlow. Okwesiboneloample:Finyelela i-Baidu nge-HTTP
