INCAZELO YOMSEBENZI

Lesi sahluko sichaza amamojula nemisebenzi ehlukahlukene ye-ESP32-PICO-D4.

3.1.CPU NEMEMORY

I-ESP32-PICO-D4 iqukethe amandla amabili aphansi i-Xtensa® 32-bit LX6 MCU. Imemori ye-on-chip ehlanganisa:

448-KB ye-ROM, futhi uhlelo luqala izingcingo zomsebenzi we-kernel
Ukuze uthole imiyalelo engu-520 KB ne-chip yokugcina idatha ye-SRAM (okuhlanganisa nememori ye-flash 8 KB RTC)

imodi, kanye nokugcina idatha efinyelelwe yi-CPU eyinhloko
Inkumbulo enensayo ye-RTC, engu-8 KB SRAM, ingafinyelelwa yi-coprocessor ngemodi ye-Deepsleep

Ku-1 kbit ye-eFuse, okuyi-256 bit system-specific (ikheli le-MAC nesethi ye-chip); ibhithi elingu-768 elisele libekelwe uhlelo lomsebenzisi, lolu hlelo lweFlash luhlanganisa ukubethela kanye ne-ID ye-chip

3.2.INCAZELO YESITORESHI

3.2.1.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-ESP32-PICO-D4 4 MB ye-SPI Flash ehlanganisiwe, ikhodi ingafakwa kumephu yesikhala se-CPU, isekele ukufinyelela okungu-8-bit, 16-bit kanye no-32-bit, futhi ingasebenzisa ikhodi. Phina i-GPIO6 ESP32 yokuthi, GPIO7, GPIO8, GPIO9, GPIO10 kanye ne-GPIO11 yokuxhuma imojuli ehlanganisiwe ye-SPI Flash, enganconyelwe eminye imisebenzi.

3.3.IKHRISTU

I-ESP32-PICO-D4 ihlanganisa i-crystal oscillator engu-40 MHz.

3.4.UKUPHATHWA KWE-RTC NOKUSETSHENZISWA KWAMANDLA OKUPHANSI

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

Imodi yokonga amandla
- Imodi esebenzayo: I-chip ye-RF iyasebenza. I-chip ingathola futhi idlulise isignali yomsindo.
- Imodi yokulala ye-Modem: I-CPU ingasebenza, iwashi lingase lilungiswe. I-Wi-Fi / i-Bluetooth baseband ne-RF
- Imodi yokulala elula: 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-WiFi ne-Bluetooth egcinwe ku-RTC. I-ULP coprocessor ingasebenza.
- Imodi ye-Hibernation: i-oscillator engu-8 MHz 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-Iyasebenza, Imodemu-ukulala, 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 we-Ultra: 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.

Imisebenzi ngezindlela ezihlukene zokusebenzisa amandla: ITABLE 5

IZIMPAWU ZIKAgesi

Ithebula 8: Amanani anomkhawulo

I-VIO kuphedi yokuphakela amandla, Bheka I-ESP32 I-Technical Specification Appendix IO_MUX, njenge-SD_CLK yokuphakelwa kwamandla kwe-VDD_SDIO.

Cindezela bese ubamba inkinobho yamandla eseceleni imizuzwana emibili ukuze uqale idivayisi.Cindezela bese ubamba imizuzwana engaphezu kwengu-6 ukuze uvale idivayisi. Shintshela kwimodi yesithombe ngesikrini Sasekhaya, futhi i-avatar engatholwa ngekhamera iboniswa esikrinini se-tft.Intambo ye-USB kufanele ixhunywe lapho isebenza, futhi ibhethri ye-lithium isetshenziselwa isitoreji sesikhashana ukuvimbela amandla. ukwehluleka.

Isitatimende se-FCC
Noma yiziphi Izinguquko noma ukuguqulwa okungagunyazwanga ngokucacile yinhlangano enesibopho sokuthobela imithetho kungasusa igunya lomsebenzisi lokusebenzisa okokusebenza.

Le divayisi ithobela ingxenye 15 yeMithetho ye-FCC. Ukusebenza kungaphansi kwemibandela emibili elandelayo:
(1) Lolu cingo lungase lungabangeli ukuphazamiseka okuyingozi, futhi
(2) Lolu cingo kufanele lwamukele noma yikuphi ukuphazamiseka okutholiwe, okuhlanganisa ukuphazamiseka okungase kubangele ukusebenza okungafuneki.

Qaphela:
Lesi sisetshenziswa sihloliwe futhi satholwa ukuthi sithobela imikhawulo yedivayisi yedijithali Yekilasi B, ngokuvumelana nengxenye 15 Yemithetho ye-FCC. Le mikhawulo iklanyelwe ukuhlinzeka ngokuvikeleka okufanele ekuphazanyisweni okuyingozi ekufakweni kwendawo yokuhlala. Lesi sixhobo sikhiqiza, sisebenzise futhi singakhipha amandla efrikhwensi yomsakazo futhi, uma singafakiwe futhi sisetshenziswa ngokuhambisana nemiyalelo, singadala ukuphazamiseka okuyingozi ezokuxhumana ngomsakazo. Nokho, asikho isiqinisekiso sokuthi ukuphazamiseka ngeke kwenzeke ekufakweni okuthile. Uma lesi sisetshenziswa sidala ukuphazamiseka okuyingozi emsakazweni noma kumabonakude, okunganqunywa ngokucisha nokuvula okokusebenza, umsebenzisi uyakhuthazwa ukuthi azame ukulungisa ukuphazamiseka ngesinyathelo esisodwa noma ngaphezulu kwezilandelayo:

-Hlehlisa noma hambisa uthi olwamukelayo.
-Khulisa ukuhlukana phakathi kwemishini nomamukeli.
-Xhuma okokusebenza endaweni yokuphuma kuyisekethe ehlukile kuleyo lapho umamukeli axhumeke khona.
— Xhumana nomthengisi noma uchwepheshe werediyo/TV onolwazi ukuze uthole usizo.

Isitatimende Sokuchayeka Kwemisebe ye-FCC:
Lesi sixhobo sithobelana nemikhawulo yokuchayeka emisebeni ye-FCC ebekwe endaweni engalawuleki .Lokhu okokusebenza kufanele kufakwe futhi kusetshenziswe ngebanga elincane elingu-20cm phakathi kwerediyetha nomzimba wakho.

ESP32TimerCam/TimerCameraF/TimerCameraX Ukuqala Ngokushesha

Nge-firmware elayishwe kuqala, i-ESP32TimerCam yakho,/i-TimerCameraF/I-TimerCameraX izosebenza ngemva nje kokuvula amandla.

Faka amandla kukhebula ku-ESP32TimerCam/TimerCameraF/TimerCameraX ngekhebula le-USB. Isilinganiso se-Baud 921600.
Ngemuva kokulinda imizuzwana embalwa, i-Wi-Fi iskena i-AP ebizwa ngokuthi “TimerCam” ngekhompyutha yakho(noma iselula), bese uyixhuma.
Vula isiphequluli kukhompuyutha(noma iselula), vakashela i URL http://192.168.4.1:81. Okwamanje, ungakwazi ukubona ukudluliswa kwevidiyo ngesikhathi sangempela nge-ESP32TimerCam/TimerCameraF/TimerCameraX esipheqululini.
