ULAWULO lwe-RTC kunye nokuSetyenziswa kwamandla aphantsi
I-ESP32 isebenzisa ubuchule obuphambili bolawulo lwamandla anokutshintshwa phakathi kweendlela ezahlukeneyo zokugcina amandla. (Jonga kwiThebhile 5).
- Imowudi yokugcina amandla
- Imo esebenzayo: Itshiphu yeRF iyasebenza. Itshiphu inokufumana kwaye idlulise isignali yesandi.
- Imodem-yokulala: I-CPU inokusebenza, kwaye iwotshi inokumiselwa. Wi-Fi / Bluetooth baseband kunye RF
- Imowudi yokulala: I-CPU inqunyanyisiwe. I-RTC kunye nememori kunye neeperipherals ULP coprocessor operation. Nasiphi na isiganeko sokuvuka (i-MAC, inginginya, isibali-xesha se-RTC okanye isiphazamiso sangaphandle) siya kuvusa itshiphu.
- Imowudi yobuthongo obunzulu: kuphela imemori ye-RTC kunye neeperipherals ezikwimo esebenzayo. Idatha ye-WiFi kunye neBluetooth yoqhagamshelwano igcinwe kwi-RTC. ULP coprocessor inokusebenza.
- Imo yokuHibernation: I-oscillator ye-8 MHz kunye ne-coprocessor ULP eyakhelwe-ngaphakathi ivaliwe. Imemori ye-RTC yokubuyisela unikezelo lwamandla icinyiwe. Sinye kuphela isibali-xesha se-RTC esikwiwotshi ecothayo kunye ne-RTC GPIO emsebenzini. Iwotshi ye-RTC ye-RTC okanye isibali-xesha sinokuvuka kwimowudi yokuHibernation yeGPIO.
- Imowudi yobuthongo obunzulu
- imo yokulala enxulumeneyo: amandla agcina imowudi yokutshintsha phakathi kwe-Iyasebenza, iModem-ubuthongo, kunye nemowudi yokuKhanya-yobuthongo. I-CPU, i-Wi-Fi, iBluetooth, kunye nexesha lokuseta kanomathotholo ukuze kuvuswe, ukuqinisekisa uqhagamshelo lwe-Wi-Fi / Bluetooth.
- Iindlela zokujonga isivamvo samandla asezantsi kakhulu: eyona nkqubo ingundoqo yimowudi yokulala obunzulu, i-ULP coprocessor ivulwa ngamaxesha athile okanye ivalwe ukulinganisa idatha yoluvo. I-sensor yokulinganisa idatha, i-ULP coprocessor ithatha isigqibo sokuba ivuse inkqubo engundoqo.
Imisebenzi kwiindlela ezahlukeneyo zokusetyenziswa kwamandla: ITHEYIBHILE 5
IIMPAWU ZOMbane
UMDA IIPARAMETHA
Uluhlu 8: Ukunciphisa amaxabiso

- Esi sifundo sisebenza kwi-M5StickC kunye ne-M5StickC PLUS
Isixhobo esivuthayo
Nceda ucofe iqhosha elingezantsi ukukhuphela isixhobo esivuthayo se-M5Burner firmware ngokwenkqubo yakho yokusebenza. Vula unzip kwaye uvule usetyenziso.
Phawula: Emva kofakelo lwabasebenzisi beMacOS, nceda ufake isicelo kwifolda yeSicelo, njengoko kubonisiwe kumfanekiso ongezantsi.
Ukutshisa i-Firmware
- Cofa kabini ukuvula isixhobo sokutshisa iSitshisi, khetha uhlobo lwesixhobo esihambelanayo kwimenyu yasekhohlo, khetha uhlobo lwefirmware oyifunayo, kwaye ucofe iqhosha lokukhuphela ukukhuphela.
- Emva koko uqhagamshele isixhobo se-M5 kwikhompyuter ngentambo yoHlobo lwe-C, kwaye ukhethe i-port ye-COM ehambelanayo, izinga le-baud lingasebenzisa uqwalaselo olungagqibekanga kwi-M5Burner, ukongeza, ungazalisa kwakhona i-WIFI ukuba isixhobo siya kudityaniswa nayo. ngexesha firmware evuthayo stage ulwazi. Emva koqwalaselo, cofa u-"Tshisa" ukuqalisa ukutshisa
- Xa i-log evuthayo ikhuthaza ukutshisa ngempumelelo, kuthetha ukuba i-firmware itshisiwe.
- Xa kuqala ukutshisa okanye inkqubo ye-firmware iqhuba ngokungaqhelekanga, ungacofa u-“Cima” ukucima inkumbulo edanyazayo. Kuhlaziyo lwe-firmware olulandelayo, akukho mfuneko yokucima kwakhona, ngaphandle koko ulwazi olugciniweyo lwe-Wi-Fi luya kususwa kwaye i-API Key iya kuhlaziywa.
Qwalasela i-WIFI
I-UIFlow ibonelela ngaphandle kweintanethi kunye web iinguqulelo zomdwelisi wenkqubo. Xa usebenzisa i web version, kufuneka siqwalasele uqhagamshelo WiFi isixhobo. Oku kulandelayo kuchaza iindlela ezimbini zokuqwalasela uqhagamshelo lwe-WiFi kwisixhobo (Ubumbeko lweBurn kunye noqwalaselo lwe-AP hotspot).
Tshisa uqwalaselo lwe-WiFi (iyacetyiswa)
I-UIFlow-1.5.4 kunye neenguqulelo ezingentla zingabhala ulwazi lwe-WiFi ngqo nge-M5Burner.
AP hotspot uqwalaselo WiFi
- Cinezela kwaye ubambe iqhosha lamandla ekhohlo ukuze uvule umatshini. Ukuba i-WiFi ayiqwalaselwanga, inkqubo iya kungena ngokuzenzekelayo kwimowudi yoqwalaselo lwenethiwekhi xa ivulwa okokuqala. Masithi ufuna ukuphinda ungenise imowudi yothungelwano emva kokuqhuba ezinye iinkqubo, ungabhekisa kumsebenzi ongezantsi. Emva kokuba i-UIFlow Logo ibonakala ekuqaleni, nqakraza ngokukhawuleza iqhosha laseKhaya (iqhosha le-M5 embindini) ukufaka iphepha loqwalaselo. Cinezela iqhosha kwicala lasekunene le-fuselage ukutshintshela ukhetho kuSeto, kwaye ucinezele iqhosha laseKhaya ukuze uqinisekise. Cinezela iqhosha lasekunene ukutshintshela ukhetho kwi-WiFi Setting, cofa iqhosha laseKhaya ukuze uqinisekise, kwaye uqale uqwalaselo.
- Emva kokudibanisa ngempumelelo kwi-hotspot ngefowuni yakho ephathwayo, vula isikhangeli sefowuni ephathwayo ukuskena ikhowudi ye-QR kwiscreen okanye ukufikelela ngokuthe ngqo kwi-192.168.4.1, faka iphepha ukuze ugcwalise ulwazi lwakho lwe-WIFI, kwaye ucofe uLungiselelo ukurekhoda ulwazi lwakho lwe-WiFi. . Isixhobo siya kuqalisa ngokuzenzekelayo emva kokuqwalasela ngempumelelo kwaye ufake imo yenkqubo.
Phawula: Iimpawu ezikhethekileyo ezifana "nendawo" azivumelekanga kwiinkcukacha ze-WiFi ezimiselweyo.
Imowudi yeNkqubo yeNethiwekhi kunye ne-API KEY
Ngenisa imowudi yenkqubo yenethiwekhi
Imowudi yenkqubo yenethiwekhi yimowudi yokudokha phakathi kwesixhobo seM5 kunye ne-UIFlow web iqonga lokucwangcisa. Isikrini siza kubonisa imeko yangoku yoqhagamshelo lwenethiwekhi yesixhobo. Xa isalathisi siluhlaza, oko kuthetha ukuba ungafumana inkqubo yokutyhala nangaliphi na ixesha. Ngaphantsi kwemeko engagqibekanga, emva koqwalaselo lokuqala oluphumeleleyo lwenethiwekhi yeWiFi, isixhobo siya kuqalisa ngokuzenzekelayo kwaye singenise imowudi yenkqubo yenethiwekhi. Ukuba awuyazi indlela yokungenisa kwakhona imo yenkqubo emva kokwenza ezinye izicelo, ungabhekisa kule misebenzi ilandelayo. ukuqalisa kwakhona, cofa iqhosha A kujongano oluphambili lwemenyu ukukhetha imowudi yenkqubo kwaye ulinde de isalathisi esilungileyo sesalathisi sothungelwano sijike luhlaza kwiphepha lemowudi yenkqubo.
