- Izinketho zehadiwe njenge-ESP32 Dev Kit C noma i-Grove Base ukuze kugwenywe ukusetshenziswa kwe-soldering.
- Ukuqaliswa kwezinhlelo ezingenayo ikhodi kanye nezinhlelo ezinamakhodi aphansi kusetshenziswa iTasmota kanye ne-ESPHome ukuze kusheshiswe intuthuko.
- Izinhlobo ezahlukene zezicelo ezisebenzayo kusukela ekuzenzekeleni kwasekhaya kanye nezinzwa zesimo sezulu kuya kuma-consoles akudala.
Uma uthanda izinto zikagesi kodwa wesaba ukusebenzisa insimbi yokunamathisela ezingxenyeni, noma ungenalo ikhono lokunamathisela izingxenye ezincane kangaka, ungakhathazeki. Kulezi zinsuku, kunezindlela eziningi zokwakha amasekethe nge- ESP32 kanye nezici zayo ngaphandle kokuncibilikisa i-solder, okuvumela noma ubani, kusukela kwabaqalayo ngokuphelele kuya kochwepheshe abafuna isivinini, ukuthi alethe imibono yakhe empilweni ngesikhathi esinqunyiwe.
Isihluthulelo sisekusebenziseni amabhodi okuthuthukisa ahlanganiswe ngaphambilini kanye nezinhlelo zemvelo ezixhuma ngokushesha. Lokhu kusenza sikwazi ukusuka ekusebenziseni i-chip engenalutho, okungaba yiphupho elibi ukuyiphatha, siye ekusebenziseni amamojula asevele eza nezikhonkwane ezilungele ukuxhumeka ebhodini lokufaka isinkwa noma ngezintambo ze-JST, okwenza kube lula kakhulu ukwenza ama-prototyping okusheshayo nokuqinile.
Ihadiwe efanelekile yokugwema ukushiswa nge-solder
Kulabo abafuna ubulula obuphelele, kunezinketho ezifana ne- ESP-32 Dev Kit C , okuyi-module ye-NodeMCU ene-port ye-USB-C. Lawa mabhodi ahambisana ne-Arduino futhi akuvumela ukuthi uhlele idivayisi ngqo, ugweme izinkinga zikagesi ngoba ahlanganisa i-USB-to-serial converter kanye nokulawulwa kwamandla ebhodini elifanayo.
Uma udinga into encane kakhulu, njenge-Seeed XIAO ESP32, kunezesekeli ezithile ezifana ne- Grove Base ye-XIAO . Leli bhodi lesisekelo likuvumela ukuthi uxhume amabhethri nezinzwa ngezixhumi ze-JST ezingamaphini angu-4, okusho ukuthi unganika amandla iphrojekthi yakho futhi wengeze izinto ezihambisanayo ngaphandle kokufaka i-solder ngisho nengxenye eyodwa - ilungele labo abangathandi kangako ubuchwepheshe.
Kulabo abafuna into encane kakhulu, efana ne-ESP-01 kodwa ngamandla e-ESP32, ukusesha kungaba nzima kakhulu, njengoba amabhodi amaningi amancane ngokuvamile adinga ukunamathiselwa kwamaphini. Kodwa-ke, ukukhetha amamojula anezipini ezifakwe kusengaphambili kuyindlela ehlakaniphile yokugcina iphrojekthi ihlanzekile futhi isebenza ngaphandle kwezinkinga.
Ukuthuthukiswa Kwekhodi Ephansi Nokungabi Nayo Ikhodi: Ukuhlela ngaphandle kokuhlupheka
Akukhona nje kuphela ngehadiwe; isofthiwe ingenziwa lula. Amapulatifomu angenayo ikhodi noma amakhodi aphansi akuvumela ukuthi udale izinhlelo zokusebenza ngokubhala ikhodi encane kakhulu, noma ngisho nokungabhali nhlobo, okunciphisa kakhulu isikhathi esithathayo ukuqala ukusebenza kwedivayisi. Lokhu kuwusizo ikakhulukazi uma kuhlanganiswa nesistimu yokulinganisa okusheshayo.
Isibonelo esicacile ukudalwa kwe-thermometer ye-WiFi. Ukusebenzisa i-ESP32 D1 Mini, inzwa ye-DS18B20, kanye nesibonisi se-I2C, idivayisi yobungcweti ingahlanganiswa endaweni ebiyelwe engangenisi isimo sezulu. Izinketho ezimbili ezivelele zokuphatha i-firmware: i-Tasmota kanye ne-ESPHome.
- I-Tasmota: Isekelwe ku-firmware ehlanganiswe kusengaphambili efakwe ngesiphequluli sewebhu. Ukwenza ngokwezifiso kwenziwa ngokusebenzisa amathempulethi nemithethoukugwema ukuthinta ikhodi yomthombo.
- Ikhaya le-ESP: Isebenza ngokusebenzisa amafayela okucushwa kwe-YAML. Kodwa-ke, idinga ukufakwa kwe- Umsizi Wekhaya ku-Raspberry Pi, kuvumela i- isilawuli esiphelele nesiqondene nawe kwezinzwa.
Inqubo yokuhlanganisa kulezi zimo iwumshini kuphela: ukubeka amakhadi erekhini, ukuxhuma izintambo ngama- terminals esikulufo , nokubopha inhlangano ekhasejini layo. Uma lokhu sekuqediwe, izibuyekezo zenziwa ngaphandle kwentambo kusetshenziswa ubuchwepheshe be-OTA (Over-The-Air).
Imibono yephrojekthi yokudala nge-ESP32
I-ecosystem yale microcontroller inkulu kakhulu kangangokuthi amathuba awapheli. Kusukela kumadivayisi asekhaya awusizo kuya ezintweni zobuchwepheshe ezimangalisayo, i-ESP32 iyisici esiyinhloko sezinto eziningi ezisunguliwe ngenxa yokuxhumeka kwayo okuhlanganisiwe kwe-WiFi ne-Bluetooth.
Emkhakheni womculo nokudlala imidlalo, izidlali zomculo eziphathwayo ezisekelwe ku-ESP32-S3 zingakhiwa, noma ngisho nama-consoles emidlalo aphrintiwe nge-3D. Kwabathandi be-retro, kungenzeka ukusebenzisa umdlalo odumile i-DOOM ku-Arduino Nano ESP32 , inselele yobuchwepheshe ejabulisayo ekhombisa amandla e-chip.
Uma ukhetha into egxile kakhulu ekukhiqizeni noma ekusetshenzisweni ekhaya, ungase ucabangele:
- Amakhibhodi ahlakaniphile: Kusukela kumakhibhodi angu-8-bit kuya kumadivayisi asebenzisa I-AI ekhiqizayo ukulingisa indlela yakho yokubhala.
- Izinhlelo zesimo sezulu: Izibonisi ze-E-Paper ezibonisa isimo sezulu ngesikhathi sangempela zisebenzisa amabhodi afana ne-FireBeetle 2.
- Ukunakekelwa kwezitshalo: Amamitha omswakama alula kakhulu, yize ayenzelwe i-ESP8266 ekuqaleni, asebenza kahle kakhulu nawo i-ESP32.
- Amawashi ahlakaniphile: Kusukela kumaphrojekthi omthombo ovulekile ngokugcwele kanye nokwenziwa ngezifiso kuya ezinhlotsheni ezihlekisayo ezenzelwe ukuba yi- iwashi elihlakaniphile elibi kakhulu kunawo wonke.
Kulabo abafuna ukuzama izinhlelo zokusebenza eziyinkimbinkimbi kakhulu, kungenzeka ukwakha ikhompyutha encane ye-Linux usebenzisa i-Arduino Nano ESP32 kanye ne-Arduino UNO R4 WiFi, besebenzisa ibhodi lokufaka isinkwa ukuze bagweme ukunamathela.
Ikhono lokudala noma yini kusukela ku-sensor yokushisa kuya ku-game console ephathwayo ngaphandle kokunamathisela i-soldering lishintsha umdlalo. Ngenxa yokuhlanganiswa kwamabhodi okuthuthukiswa kwesimanje , izixhumi ezisheshayo, kanye nesofthiwe elula, noma ubani angasuka embonweni ongaqondakali aye kudivayisi esebenza ngokugcwele emahoreni ambalwa nje.
