Qhov zoo ntawm kev siv 1st txoj kev, yog tias nws yoog raws ntau dua. Koj tuaj yeem xaiv lub cim kom pom ntawm koj cov zaub, suab thiab lwm yam. Kuv "kev tshwm sim" tau qhia ntawm daim duab saum toj no.

Tom ntej no, cia qhov program ESP module.

Kauj Ruam 12: Programming ESP8266-01 Module

Cia peb pib los ntawm nyem peb lub ESP8266 module. Feem ntau cov modules los nrog lub Hoobkas tsim khoom. nws tuaj yeem sib txuas lus nrog cov qauv los ntawm kev siv hu ua AT cov lus txib. Thiab qhov software no tsis pub siv cov qauv xws li cov tswj ib leeg. Txhawm rau siv lawv zoo li cov tswj ib leeg peb yuav tsum tau lwv lub Hoobkas firmware thiab teeb tsa ib qho tshiab.

Txhawm rau ua qhov no peb yuav siv esptool. Tshaj li qhov peb xav tau txuas peb cov qauv rau PC kom tshem tawm cov firmware. Txhawm rau ua qhov no koj xav tau TTL hloov pauv + ob peb yam ntxiv. Tab sis muaj txoj hauv kev yooj yim dua:). Tsuas yog yuav ntawm aliexpress lossis ebay USB rau ESP8266 ESP-01 Wi-Fi Adapter Module w/ CH340G Tsav Tsheb.

Txuas tus ESP8266 tus qauv rau hauv TTL hloov pauv raws li qhia hauv daim duab, thiab txuas nws mus rau USB chaw nres nkoj.

Yog tias koj muaj tus hloov pauv tib yam li kuv, tom qab ntawd los ntawm nws tus kheej koj yuav tsum hloov pauv mus rau "Prog" txoj haujlwm. Nrhiav qhov twg esptool tau teeb tsa (ib txwm nyob qhov twg zoo li C: / Program Files (x86) Python36-32 / Scripts.

Tau kawg xaiv qhov chaw nres nkoj raug. Hauv kuv qhov xwm txheej nws yog COM5. Koj tuaj yeem tshawb xyuas qhov chaw nres nkoj uas ESP tau teeb tsa los ntawm Tswj vaj huam sib luag - Txheej Txheem - Tus Thawj Tswj Ntaus Ntawv.

Nruab firmware (Kuv coj nws los ntawm no: https://micropython.org/download#esp8266) los ntawm kev ntaus ntawv:

nab hab sej esptool.exe --port COM5 --baud 460800 write_flash --flash_size = ntes 0 C: / path_to_firmware / esp8266-20180511-v1.9.4.bin

Ok, tam sim no peb tau npaj rau upload cov ntawv micropython rau ESP8266.

Kuv tab tom siv Adafruit MicroPython Tool (ampy) rau qhov no.

Tab sis niaj hnub no muaj lwm txoj hauv kev hu ua Esplorer. Nov yog app nrog cov neeg siv cuam tshuam, tso cai rub tawm cov ntaub ntawv rau ESP cov qauv.

Koj tuaj yeem pom cov lus qhia yuav ua li cas rau nruab ampy ntawm no. Yog li, muab qhov hloov pauv ntawm TTL hloov mus rau "UART" txoj haujlwm. Peb yuav tsum upload cov ntaub ntawv:

• wifimgr.py - tus tswj hwm wifi rau txuas rau wifi network
• main.py - peb tsab ntawv tseem ceeb

Hauv kab hais kom ua hom: ampy --port COM5 muab C: / path rau koj cov ntaub ntawv

Ntaus "enter". Tom qab ob peb feeb koj yuav tsum pom kab hais kom ua. Nws txhais tau hais tias cov ntaub ntawv tau muab rub tawm. Koj tuaj yeem tshawb xyuas cov npe ntawm cov ntaub ntawv ntawm ESP los ntawm ampy hais kom ua:

ampy --port COM5 ls

Los ntawm kuv qhov kev paub nws zoo dua los upload main.py tom qab koj tau rub tawm txhua cov ntaub ntawv tsim nyog. nws yog li ntawd, vim tias sai li sai tau koj yuav upload main.py - ESP8266 module yuav rov pib dua thiab pib ua haujlwm main.py cov ntaub ntawv. Yog li hauv qhov no yog tias koj sim xa lwm cov ntawv, qee zaum txheej txheem upload yuav ua tsis tiav. Tab sis nws tsis txhais tau tias txhua yam ploj:), tsuas yog sim zaum ob, thiab koj yuav ua tiav (dua, los ntawm kuv qhov kev paub dhau los).

Txhua cov ntaub ntawv rau txoj haujlwm no muaj nyob ntawm no:

Kauj Ruam 13: Txuas rau Koj Lub Network WiFi. Tau ceeb toom

yog tias txhua yam ua tau zoo, rov pib dua tus qauv, rov txuas lub TTL hloov mus rau USB chaw nres nkoj ntawm koj lub PC.

Tom qab ESP pib, nrhiav WiFi network tshiab hu ua "Wifimanager". Txuas rau nws nrog koj lub PC lossis xov tooj, tom qab ntawd mus rau IP chaw nyob 192.168.4.1.. Ntawm no koj tuaj yeem txuas koj li ESP mus rau WiFi network hauv zos. Xaiv WiFi network koj yuav siv, ntaus tus password, ntaus "Xa".

Yog tias txhua yam raug, koj yuav pom cov lus "ESP ua tiav txuas nrog XXXX network". Koj ESP tam sim no txuas nrog koj lub network WiFi thiab npaj tau. Thaum nws txuas nrog WiFi nws yuav txuas rau Domoticz server. Shorty koj yuav tsum tau txais ntawv ceeb toom ntawm koj lub xov tooj ntawm tes.

Koj tuaj yeem taug qab cov txheej txheem hauv "Teeb"/"Log".
