I-NodeMCU: ipulatifomu yomthombo ovulekile we-IoT

INodeMCU iyisimo sokuqalisa ipulatifomu ye-IoT (I-Intanethi Yezinto), noma i-Intanethi yezinto, umthombo ovulekile. Sebenzisa i-firmware esebenza i-ESP8266 SoC evela ku-Espressif Systems esivele siyihlaziye kule bhulogi, kanye nehardware esekwe kumodyuli ye-ESP-12, enokuxhumeka okungu-11 kwe-GPIO, enye yazo eyi-10-bit analog (1024 amanani wedijithali), njengoba ungafunda kuleyo athikili engibhekisa kuyo .

Leli gama INodeMCU isho i-firmware hhayi ama-dev kits, yize muva nje isetshenziswa njengegama elifanayo lesikhulumi esigcwele. Futhi, kufanele wazi ukuthi lawa ma-module asebenzise uLua njengolimi, ekuqaleni, kepha njengoba uzobona ukuthi sekuguqukile. Eqinisweni, babakha kuphrojekthi ye-eLua kanye ne-Espressif's SDK engasebenzi ye-ESP8266, futhi besebenzisa amaphrojekthi womthombo ovulekile ukubhala izingcezu ezingekho njenge-lua-cjson, spiffs, njll. Uma kwenzeka ungazi, uLua wulimi lohlelo olubalulekile futhi oluhlelekile olulula ngokwanele ukuthi lungasetshenziswa njengolimi oluhunyushiwe olunama-semantics anwebekayo.

I-NodeMCU

Sekuthandwa kakhulu Le module ingenye yalabo abasebenzisa i-ESP8266, ngoba isetshenziswa kakhulu kumaphrojekthi we-IoT, imfashini namuhla. Ngemuva kokukhangisa nge-ESP8266 kwa-Espressif Systems ngo-2013, ngemuva konyaka, ngo-Okthoba 2014, amafayili we-firmware wokuqala we-NodeMCU aqala ukuhanjiswa ku-GitHub. Ezinyangeni ezimbili kamuva, ekupheleni kwalowo nyaka, iphrojekthi yaqala ukukhula yafaka neplatifomu evulekile yezingxenyekazi zekhompyutha.

Kancane kancane wakhula futhi wanezela imitapo yolwazi eyengeziwe yephrojekthi, njengeMQTT kaContiki ukuze ipulatifomu isekele umthetho olandelwayo we-IoT MQTT, kusetshenziswa iLua ukufinyelela. Esinye isibuyekezo esikhulu sizofika ngo-2015, lapho i-Devsaurus ifaka umtapo wezincwadi we-u8glib weNodeMCU, ngaleyo ndlela ikuvumela ukuthi ulawule kalula izibonisi ze-LCD, OLED ne-VGA. Kancane kancane bonke abathuthukisi bokuqala bayishiya iphrojekthi ehlobo lika-2015 futhi bathatha isikhundla sabahlanganyeli abazimele. Ngo-2016, i-NodeMCU isivele ifake ngaphezu kwamamojula ahlukile angama-40 ...

Kuzofaka phakathi i- I-ESP8266 Core ye-Arduino IDE, ukusebenza ngeplatifomu namabhodi wokuthuthukisa we-Arduino, avumela abasebenzisi nabenzi abaningi ukuthi bakhe amaphrojekthi abo besebenzisa le nkundla.

Ukuphina

Ngokuqondene ne-Pinout, bekuvele kuxoxwe kokunye okuthunyelwe kwebhulogi mayelana ne-ESP8266, kepha izikhonkwane ezivelele kakhulu yilezi:

• Phina 0 *: GPIO 16 ye-GPIO funda / bhala kuphela.
• Phina 1: GPIO 5
• Phina 2: GPIO 4
• Ipenti 3: GPIO 0
• Phina 4: GPIO 2
• Phina 5: GPIO 14
• Phina 6: GPIO 12
• Phina 7: GPIO 13
• Phina 8: GPIO 15
• Phina 9: GPIO 3
• Phina 10: GPIO 1
• Phina 11: GPIO 9
• Phina 12: GPIO 10
• Ezinye zigodliwe, noma zisebenzela ukunikezwa kwamandla (GND, Vcc), kanye namanye amasiginali.

Izikhonkwane ziyatholakala zingahluka ngokuya ngohlobo noma imodeli, kepha lokho kujwayelekile.

Ezinye izici zeNodeMCU

El I-NodeMCU kunentengo efanayo ne-ESP-201, nge- € 7 approx. ku-amazon, nakho konke okudingayo kufakwe kuyo, ngakho-ke ukusetshenziswa bekungeke kube lula. Amanye amamojula adlula u- € 10, kepha afaka ezinye izinto ezingeziwe, njengamaphaneli e-LCD, njll.

Ungakwazi landa i-firmware okulawula kusuka IGitHub mahhala nezilimi ezinjenge-C ++, i-Python, i-BASIC, iJavaScript, nezinye ezinjengeLua uqobo zingasetshenziswa. Khumbula ukuthi ingumthombo ovulekile, ngakho-ke, ikuvumela ukuthi ufunde kule phrojekthi noma uyiguqule ngokukhululeka uma udinga ukwengeza izici noma ukushintsha noma iyiphi ipharamitha.

Ngabe ibhodi yentuthuko ifaka ini?

La Ibhodi lokuthuthukisa leNodeMCU livame ukufakwa kukhithi Inechweba layo le-microUSB lokuluhlela nokuyinika amandla, kanye nesiguquli se-serial-USB, ama-terminals engiwashilo esigabeni se-pinout, ama-LED nenkinobho yokusetha kabusha ehlanganiswe ebhodini. Vele, ngokufaka i-ESP8266 SoC yokuxhuma kwe-WiFi, i-antenna yenyoka nayo iphrintiwe esikrinini ku-PCB.

Noma kunjalo, ukuba ne- abakhiqizi abahlukahlukene, izinhlobo nezinhlobo, ngayinye yazo inefilosofi yayo futhi ingafaka okungeziwe kwayo noma ibe nenqubo ehlukile kuye ngenhloso ipuleti eyenzelwe ngayo. Isibonelo, njengoba uzobona ngokuhamba kwesikhathi, ungafaka indawo ye-ESP12 chip ye-ESP12E kwezinye izinhlobo, noma i-CH340G esikhundleni se-CP2102 yokuguqulwa kwe-serial, njll.

Imvamisa main Abakhiqizi bebhodi leNodeMCU Ziyi-Amica, FBlue, Lolin / Wemos, DOIT / SmartArduino, AZ-Delivery, njll. Ngokungeziwe kubahlinzeki abahlukahlukene, uzothola nezinguqulo eziningana:

• Isizukulwane sokuqalaI-devkit v0.9 yinguqulo yokuqala yeNodeMCU ene-ESP12 enefleshi engu-4MB ku-ESP8266, kodwa ngezikhonkwane ezimbalwa ze-GPIO kunenguqulo ye-ESP12E amamodeli amanje asuselwa kuyo. Manje ayisasebenzi futhi awukwazi ukuyithenga.
• Isizukulwane sesibili: yinguqulo v1.0 / v2.0, eyenziwe ngu-Amica, inkampani yaseJalimane uGerwin Janssen ukuthuthukisa i-v0.9 edlule. Bayithande kakhulu kangangoba yagcina isiyinguqulo esemthethweni yeNodeMCU. Kuqale ukusebenzisa i-ESP12E nangomugqa owengeziwe wezikhonkwane zokuxhuma. Abanye abakhiqizi bagcine bekopisha le nguqulo futhi, besebenzisa le modeli ye-hardware evulekile njengesisekelo.
• Isizukulwane sesibili- i-v1.0 / v3 yenzelwe uLolin / Wemos ngenkathi bethatha isinqumo sokwenza uhlobo oluthuthukisiwe ngezinguquko ezithile ezincane. Ushintsho olukhulu bekungukufaka isiguquli se-serial ye-CH340G esikhundleni se-CP2102, okwenza ichweba le-USB liqine ngokwengeziwe. Njengamanje iyimodeli ethengiswa kakhulu kunazo zonke.

Okwamanje, lezi yizona intuthuko ebaluleke kakhulu lokho kufanele ukwazi, yize ezinye sezivele ziphelelwe yisikhathi.

Yini engenziwa ngeNodeMCU?

Ongakwenza ngebhodi le-NodeMCU nge-IoT kungahluka kakhulu, futhi umkhawulo umcabango wakho. Kepha nakhu ke eminye imibono eyisampula ongayisebenzisa ngenxa yemisebenzi yokulawulwa okuvela kwi-Intanethi, ukuxhumana, njll.

• Dala eyakho Isiteshi Sezulu ngomswakama, izinzwa zokushisa, njll., futhi ukwazi ukuthola imiphumela yokulinganisa kusuka kunoma iyiphi indawo enoxhumano lwe-Intanethi. Vele ungasebenzisa noma yiluphi olunye uhlobo lwenzwa noma izinto ukwenza amaphrojekthi afanayo.
• Ukuzenzakalela okuxhunyiwe, kubangela ukuthi isenzo senziwe ngumfutho, njengokulawula amalambu e-LED, ukushintsha ukudlulisela, ukwenza noma yiluphi uhlobo lwe-actuator, njll.
• Dala a Iseva ye-NTP, nezinye izinhlobo zamasevisi zamadivayisi wakho axhunyiwe.
• Izinhlelo zokubeka okwangaphakathi kwamakhaya noma izakhiwo ezisebenzisa i-GPS.
• Amathoyizi azo zonke izinhlobo, ezishintshayo ekhaya yendlu, njll.

Imininingwane engaphezulu - Izifundo ze-Arduino

Manje uyazi izici ezibaluleke kakhulu zamabhodi we-NodeMCU kanye ne ungaqala ukusebenzisa kumaphrojekthi wakho we-IoT wesikhathi esizayo kanye namabhodi akho e-Arduino nokunye okunjalo ...
