Ib tus phooj ywg ntawm kuv xav tau qee qhov wifi tswj lub zog hluav taws xob rau nws lub sam thiaj - koj paub, cov khoom ib txwm muaj: ywg dej cov nroj tsuag, nqa lub teeb thaum nws tsaus ntuj. Yog li tom qab qee qhov tshawb xyuas lub vev xaib, Kuv tuaj nrog MEROSS MSS620 - ob lub qhov hluav taws xob, wifi tswj.
Tau kawg kuv tsis tau nrhiav kom khaws thawj lub firmware - tej zaum kuv yog tsev kawm ntawv qub, tab sis kuv tsis nyiam tso siab rau qee lub tuam txhab suav nrog nrog kuv li WiFi password;) Txij li thaum kuv tsis tuaj yeem pom cov ntaub ntawv hais txog tus qauv tshwj xeeb, kuv xaiv mus nrog kuv lub siab: 2.4GHz Wifi, qee qhov app … txoj cai: suab zoo li ESP8266.
Kauj ruam 1: Qhib
Lub pob khoom tuaj txog, thiab nws yog: Qhov paub zoo pom MCU Module, RX, TX, GND thiab qee lub jumper sau tias "KEY". Nqa kuv lub ntsuas txuas mus ntxiv thiab lees paub: txhua cov cim qhia mus rau qhov twg kuv xav kom lawv mus rau ESP12 - qhov no yuav yooj yim … yog li kuv xav.
!!!! Ib lo lus ceeb toom ua ntej kuv mus: tsis txhob siv lub cuab yeej uas siv hluav taws xob qhib hluav taws xob! Mains voltage tuaj yeem ua mob hnyav rau koj, hauv qhov xwm txheej phem tshaj plaws tua koj! Yog tias koj tsis muaj Lub Tswv Yim yuav ua li cas txog lub zog hluav taws xob, nug ib tus neeg uas ua! Yog tias koj tsis paub leej twg, leej twg tuaj yeem pab koj - tsis txhob kov cov khoom ntawd !!
Txawm li cas los xij - tau txais USB Serial adapter thiab txuas nrog RX/TX/GND - ua haujlwm zoo li ntxim nyiam. Qhov tso tawm yog 9600 baud, MCU tau muab cov lus ntawm cov xwm txheej tsis meej, kos npe zoo ntawm lub neej. ESP8266's GPIO0 yuav tsum tau rub mus rau GND kom tau MCU rau hauv hom nyem - yog li jumper hla tus KEY pins, txhawb lub zog… vim li cas MCU tseem tham nrog kuv? Yog lawm: tsis muaj kev hloov pauv, yog tias KEY jumper raug kaw lossis qhib - qhov tsis yooj yim sua rau ESP12.
Kuv tau nkees nkees-ntsaws lub cuab yeej, yog li kuv tau siv lub zog txawm hais tias 3v3 ntawm kuv lub USB-Serial adapter thiab sim kho vajtse rov pib dua ntawm tus qauv-uas tsis tau ua dab tsi, ib yam nkaus. TWS ??
Ntsuas qee qhov kev tswj hwm tus lej ntau dua ntawm tus qauv tsis tau pab txhua: yuav tsum muaj qee qhov rub tawm, uas yuav tsum tau ntsuas nrog lub ntsuas yooj yim - lawv tsis yog.
Yog li kuv txiav txim siab mus txoj kev nyuaj: Kuv paub tias txhua tus xav tau tus pin nyob ntawm qhov chaw raug rau ESP12 tus qauv. Cia peb tau txais ib qho nyob ntawd!
Kauj Ruam 2: Qee Yam Paub
Me ntsis tawm ntawm cov cuab yeej raug rau txoj haujlwm kuv ua tiav desoldered MCU module thiab poob ESP12 tshiab hauv - bang, ua haujlwm tawm ntawm lub thawv.
Kauj Ruam 3: Koj Yog Leej Twg?
Tab sis kuv xav paub: dab tsi kuv nyuam qhuav tshem tawm? Tau tshem ntawm HF Shield piav qhia tus cwj pwm coj txawv txawv: qhov ntawd tsis yog ESP module txhua! Sab hauv kuv pom MediaTek MT7662 - me ntsis sib xyaw ntawm ESP8285 thiab ESP32, ib qho nti MCU, Wifi & BT. Ib qhov twg ntawm txoj kev lawv hloov MCU Modules.
Yog li - MSS620 yog hackable. Tab sis yuav tsum paub tias nws yuav siv qee qhov txuas thiab tshem tawm ntawm MCU tus qauv.
Yog tias koj txaus siab rau txoj haujlwm pin:
Relays / Raws: IO12 / IO4
LEDs: IO5 (ntsuab/qis dua)/IO13 (liab/saum)
Hloov: IO14 (Pulldown, yog li nyeem nws ntawm INPUT_PULLUP)
