Uma ukhumbula, sesivele sethule ifayela le- I-chip ye-ESP8266, i-IC esebenzayo yokuxhuma i-WiFi ongayisebenzisa kumaphrojekthi wakho nge-Arduino. Manje sekuyisikhathi sakho phendukela ku-Wemos D1, Ibhodi elifaka le chip efanayo futhi elisebenzisekayo ngobuningi bamaphrojekthi we-DIY. Uma ufisa, ungathola imibhalo yaleli bhodi kuwebhusayithi esemthethweni yeWemos, lapho ungakhona ukufinyelela kusuka lapha.
Te Ngincoma ukubona indatshana yethu ku-ESP8266 engikubeke kusixhumanisi esedlule, ngoba kungenjalo, lapho uqala nge-Wemos D1 uzolahleka ngandlela thile uma ungenaso isisekelo. Kufanele futhi ubone omunye umhlahlandlela wethu ku- I-NodeMCU, enokuthintana kakhulu ne-ESP8266 kanye nalesi sakhi esibhekene naso namuhla. Kulezi zihloko ezimbili uzothola nezibonelo zekhodi ukuze ukwazi ukuhlela i-ESP8266, imitapo yolwazi edingekayo ye-Arduino IDE, njll.
Abesifazane
Kuyinto a Umkhiqizo waseChina owukhiqizayo lolu hlobo lwamabhodi wokuthuthukiswa kwe-elekthronikhi nezihlangu zawo ezivela kuwo iwebhusayithi esemthethweni. Phakathi kwemikhiqizo yayo efakiwe, ungathola ibhodi le-Wemos D1.
I-Wemos D1
Kunamapuleti amabili athakazelisa kakhulu ahlinzekwa yiWemos, elinye lamaWemos D1 kanti elinye udadewabo omncane I-Wemos D1 Mini, encane, noma ezinye izinhlobo ezibiza kakhulu njengePro (ene-16M flash esikhundleni se-4M), njll. Kwabaningi, lingenye yamabhodi wabo wokuthuthuka abawathandayo we-chip ye-ESP8266, noma ngaphezulu kwe-NodeMCU, noma amanye amamojula ane-ESP8266, kwezinye izinhlelo zokusebenza.
Ku-athikili yeNodeMCU ne-ESP8266 engiyicaphune, ungafunda ukuthi i-chip ye-ESP8266 ingahlanganiswa kumamojula ahlukahlukene anjenge-ESP12, ESP12E, njll. Uma kwenzeka kuba iWemos D1 Mini, Kukhulu ngosayizi omncane kunokusebenzisa i-ESP12 ngqo, ngobukhulu be-34.2 × 25.6mm kanye no-3 gram wesisindo.
Kepha uma usebenzisa i-ESP12 engenalutho, uzoba nokushiyeka okuningi. Nge-Wemos D1 Mini unezinzuzo nokungeziwe okufana ne- imbobo ye-microUSB kanye ne-serial converter ngokuxhumeka kwakho. Kubandakanya nesilawuli sevolthi ukuyondla ngqo ngesokhethi se-Arduino's 5V, futhi izifunda zangaphakathi zizonakekela ukudlulisa lawo ma-volts kumandla we-module adingeka ngempela.
Enye inzuzo ye- Imikhiqizo yama-Wemos ngukuthi bayakuvumela landisa ukusebenza kwayo ngezihlangu, akhona ngobuningi ukulawula izinjini (abashayeli), imojuli yokudlulisa, izikrini ze-OLED, izinzwa zokushisa nomswakama, i-PIR, inkinobho, njll. Okusho ukuthi, ikunikeza izindawo eziningi zokusebenzisa lezi zingxenye ngokulawula okuvela kwi-Intanethi noma kunethiwekhi ye-WAN.
Noma kunjalo akuyona yonke into enenzuzoNgokuphambene nalokho, inezinombolo ezimbalwa zezikhonkwane ezitholakalayo, ezinama-GPIO ayi-11 ngokuqhathaniswa nangu-17 onawo kwamanye amamojula anjenge-ESP12 noma i-NodeMCU. Kodwa-ke, lokhu akufanele kube yinkinga enkulu, ngoba amaphrojekthi amaningi awadingi okungaphezu kwalezi zikhonkwane eziyi-11, noma ngabe konke kuzoncika kulokho okudingeka umsebenzisi ngamunye ...
Izici, i-pinout, namanani
Ukusekelwa ku ESP12E, yabelana ngeziciNgakho-ke, ngizokunikeza isifinyezo lapha:
- Isebenza ngejubane le-80 kuye ku-160Mhz.
- Imemori engu-4 MB
- Ukunikezwa kwamandla ka-3.3v, yize kunesiguquli sokukwazi ukuyondla nge-5V ye-Arduino uma ufuna.
- 11 GPIO, konke kune-PWM ngaphandle kwe-D0.
- Iziphazamiso
- I2C ibhasi
- Okokufaka kwe-Analog 1 (3.2v max)
- Isixhumi seMicroUSB
El intengo kusuka cishe ku- € 2 nokuphakama, kuze kufike ku- € 20, kuya ngemodeli. Ungayithola ezitolo eziningi ezikhethekile naku-inthanethi. Ngakho-ke ungaba ne-Wemos D1 Mini eshibhile kakhulu, engaphezu kwe-NodeMCU nangaphezudlwana nje kwentengo yemodyuli ye-ESP12E ngaphandle kokunye okungeziwe ...
para thenga le mikhiqizo nezihlangu zawo, Wemos inikeza isigaba se Isitolo se-Inthanethi, kepha ikuqondisa kabusha ku- I-AliExpress, ngakho-ke yindawo lapho isatshalaliswa khona ngokusemthethweni.
El ukukhipha webhodi eliyisisekelo le-Wemos D1 Mini yile:

- I-5V: yokunikezwa kwamandla.
- 3V3: 3.3v ugesi.
- I-RST: ixhunywe ku-RST, okungukuthi, ukusetha kabusha.
para thola i-datasheetUsuyazi vele ukuthi ungathola imibhalo kuwebhusayithi esemthethweni yeWemos engiyishiye ekuqaleni kwendatshana. Futhi bane-Wiki ephelele lokho ngiyakutusa, ngoba ungathola usizo oluningi ... Baze babe nalo izifundo.
