Wemos: kunye neebhodi zakho zophuhliso nge-ESP8266

Ukuba uyakhumbula, sele singenisile I-chip ye-ESP8266, i-IC ebonakalayo yokunxibelelana kwe-WiFi ukuyisebenzisa kwiiprojekthi zakho kunye neArduino. Ngoku lithuba lakho ukujika kwi-Wemos D1, Ibhodi ebandakanya le chip inye kwaye ikwasebenza ngokusebenzayo kwinkitha yeeprojekthi ze-DIY. Ukuba unqwenela, ungafumana amaxwebhu ale bhodi kwiwebhusayithi esemthethweni yeWemos, apho unokufumana khona ukufikelela apha.

Te Ndincoma ukubona inqaku lethu kwi-ESP8266 endibeke kwikhonkco elidlulileyo, kuba kungenjalo, xa uqala ngeWemos D1 uya kulahleka ngakumbi ukuba awunasiseko. Kuya kufuneka ubone esinye isikhokelo kwi Indlela yeNodeMCU, enento yokwenza ne-ESP8266 kunye neli candelo sijongana nalo namhlanje. Kula manqaku mabini uya kufumana imizekelo yekhowudi ukuze ube nakho ukwenza inkqubo ye-ESP8266, iilayibrari eziyimfuneko zeArduino IDE, njl.

Abafazi

Yiyo Uphawu lwaseTshayina oluvelisa olu hlobo lweebhodi zophuhliso lwe-elektroniki kunye namakhaka abo kubo iwebhusayithi esemthethweni. Phakathi kweemveliso zayo ezibonakalayo, unokufumana ibhodi yeWemos D1.

Abafazi D1

Zimbini iipleyiti ezinomdla kakhulu ezinikezwe yiWemos, enye yeWemos D1 kwaye enye ingudade wayo omncinci I-Wemos D1 Mini, encinci, okanye ezinye iinguqulelo ezibiza kakhulu njengePro (nge-16M flash endaweni ye-4M), njl. Kwabaninzi, yenye yeebhodi zophuhliso abazithandayo ze-chip ye-ESP8266, nokuba ngaphezulu kweNodeMCU, okanye ezinye iimodyuli ezine-ESP8266, kwizicelo ezithile.

Kwinqaku le-NodeMCU kunye ne-ESP8266 endilicatshulileyo, ungafunda ukuba i-chip ye-ESP8266 inokudityaniswa kwiimodyuli ezahlukeneyo ezinjenge-ESP12, ESP12E, njl. Kwindaba ye I-Wemos D1 Mini, Inkulu kancinci ngobukhulu kunokusebenzisa nje i-ESP12 ngokuthe ngqo, ngobukhulu be-34.2 × 25.6mm kunye ne-3 gram yobunzima.

Kodwa ukuba usebenzisa i-ESP12 engenanto, uya kuba neentsilelo ezininzi. Nge-Wemos D1 Mini unezibonelelo kunye nezongezo ezinje nge Izibuko le-microUSB kunye ne-serial converter ngonxibelelwano lwakho. Ikwabandakanya umlawuli wevolthi yokuyondla ngokuthe ngqo ngesokethi ye-Arduino's 5V, kwaye isekethe yangaphakathi iya kukukhathalela ukuhambisa ezo volts kumandla ombane afunwa yimodyuli.

Olunye uncedo lwe Iimveliso zeWemos kukuba bayavumela Yandisa ukusebenza kwayo ngamakhaka, ezikhoyo ngobuninzi bokulawula ii-motors (abaqhubi), imodyuli yokudlulisa, izikrini ze-OLED, iqondo lobushushu kunye neenzwa zokufuma, i-PIR, iqhosha, njl. Oko kukuthi, ikunika uninzi lwezixhobo zokusebenzisa ezi zinto ngolawulo kwi-Intanethi okanye kwinethiwekhi yeWAN.

Nangona kunjalo ayizizo zonke izinto eziluncedoNgokuchasene noko, inenani elincinci lezikhonkwane ezikhoyo, linee-GPIO ezili-11 xa kuthelekiswa ne-17 onazo kwezinye iimodyuli ezinje nge-ESP12 okanye iNodeMCU. Nangona kunjalo, oku akufuneki ukuba yingxaki enkulu, kuba iiprojekthi ezininzi azidingi ngaphezu kwezi zikhonkwane zili-11, nangona yonke into izakuxhomekeka kwinto efunwa ngumsebenzisi ngamnye ...

Iimpawu, i-pinout, kunye namaxabiso

Ukusekwa kwi- ESP12E, yabelana ngeempawuKe ngoko, ndiza kukunika isishwankathelo apha:

• Imemori ye-4 MB
• Ukunikezelwa kwamandla kwe-3.3v, nangona inesiguquli ukuze ikwazi ukuyondla ngeArduino 5V ukuba uyafuna
• 11 GPIO, zonke zine-PWM ngaphandle kwe-D0.
• Ukuphazamiseka
• I2C ibhasi
• Igalelo le-Analog 1 (3.2v max)
• Isinxibelelanisi seMicroUSB

• I-TX: iqhagamshelwe kwi-TXD ye-ESP8266, ye-TXD.
• I-RX: iqhagamshelwe kwi-RXD ye-ESP8266, yeRXD.
• A0: idityaniswe kwipini enegama elifanayo njengegalelo le-analog.
• I-D0: yi-GPIO16 yemodyuli, kwaye isetyenziswa njenge-I / O.
• I-D1: imodyuli ye-GPIO5, efana ne-I / O, i-PWM, ukuphazamiseka, i-I2C, kunye ne-SCL.
• I-D2: ukuya kwi-GPIO4, ye-I / O, i-PWM, ukuphazamiseka, i-I2C, i-SDA.

• G: yi-GND (umhlaba), unxibelelwano lomhlaba.
• I-5V: yokubonelela ngombane.
• I-3V3: 3.3v unikezelo lwamandla.
• RST: iqhagamshelwe kwi-RST, Oko kukuthi, ukuseta kwakhona.

ukuba fumana iphepha ledathaSele uyazi ukuba ungafumana amaxwebhu kwiwebhusayithi esemthethweni yeWemos endiyishiye ekuqaleni kwenqaku. Kwakhona bane-Wiki epheleleyo Ndikucebisa, kuba unokufumana uncedo oluninzi ... Bade babe nabo abaqeqeshiweyo.
