Kuv pom qhov no pib ua haujlwm ib nrab xyoo dhau los. Kuv tsis paub tseeb vim li cas kuv tsis tau xa qhov no tab sis yuav sim ua tam sim no.

Yog li lwm xyoo no Lazy Old Geek (L. O. G.) pom qhov no Qhia:

www.instructables.com/id/ESP8266-WiFi-Anal…

Kuv xav tias tus sau tau ua txoj haujlwm zoo yog li kuv txiav txim siab ua kuv tus kheej.

Nws siv NodeMCU ESP8266. Kuv tsis muaj ib qho tab sis kuv xav tias lawv nyob ntawm ESP-12. Zoo ESP-07 zoo ib yam li ESP-12 yog li kuv tau xaj ob peb ntawm lawv. Kuv kuj tseem yuav qee tus 2mm txiv neej lub taub hau thiab qee tus poj niam lub taub hau yog li kuv tau teeb tsa txiv neej lub taub hau rau ESP-07 thiab coj poj niam lub taub hau taub hau thiab tso qee lub xov hlau rau lawv kom lawv haum hauv daim ntawv qhia zaub mov. (Saib daim duab)

Hloov chaw ntawm Nodemcu, Kuv siv ESP-07.

Kuv cov zaub yog 2.8 ILI9341 zaub tej zaum yuav ntawm ebay. Qhov no yog me ntsis loj dua li ib qho hauv thawj.

Okay, Kuv tsim PCB nrog 3.3V cov khoom siv, 2.2mm header pins rau ESP-07 thiab txuas rau cov zaub.

Txuas nrog yog Eagle Cadsoft cov ntaub ntawv kuv siv los ua PCB thiab cov phiaj xwm.

CEEB TOOM: Cov txheej txheem hauv daim duab tsis pom zoo nrog Eagle cov ntaub ntawv. Kuv poob Eagle cov ntaub ntawv siv AMS1117 3.3V tus tswj hwm qhia hauv daim duab no.

Cov ntaub ntawv Eagle txuas tau siv 1N5817 diode los tso 5v rau 4.4 (?) V rau ESP-07. Rau kuv teeb tsa, nws zoo li ua haujlwm tau zoo tab sis kuv paub tias nws tawm ntawm qhov tshwj xeeb. Kuv tsis pom zoo siv lub diode (thiab kuv tsis paub tseeb vim li cas kuv thiaj ua nws).

Yog tias koj tau tshwm sim xav siv cov ntaub ntawv Eagle, tom qab ntawv koj yuav muaj peev xwm hloov pauv tau. Thov hloov cov txheej txheem thiab pawg thawj coj los siv tus tswj hwm 3.3v.

PCB no tseem xav tau USB-Serial adapter nrog RTS thiab DTR raws li tau piav qhia hauv Cov Lus Qhia no:

Kauj ruam 3: Arduino Sketch

Nov yog cov tsev qiv ntawv kuv siv rau 2.8 zaub:

Cov tsev qiv ntawv: Rub tawm cov ntawv zip:

github.com/adafruit/Adafruit_ILI9341

github.com/adafruit/Adafruit-GFX-Library

Pib Arduino:

Nyem rau

Nrhiav cov ntawv zip saum toj no, qhib thiab rub tawm

Tam sim no kuv tab tom siv Arduino version1.8.12.

Txoj hauv kev yooj yim tshaj plaws rau kuv los teeb tsa ESP8266 yog siv Tus Thawj Saib Xyuas Haujlwm siv txoj hauv kev no:

github.com/esp8266/Arduino#installing-with…

Thaum kuv tau ua qee qhov kev sim nrog ESP-07 Kuv xaiv "Generic ESP8266 module".

www.instructables.com/id/ESP-07-Test-PCB/

Txawm li cas los xij, qhov no tsis ua haujlwm rau Sketch no, yog li rau Boards, hauv qab nqe ESP8266 (2.6.3), xaiv NodeMCU 0.9 (ESP-12 Module lossis NodeMCU 1.0 (ESP-12 Module)

Pawg Thawj Coj teeb tsa lub hauv paus zoo li ua haujlwm tau zoo.

Yog, Kuv paub tias qhov no tsis yog ESP-12 tab sis kuv twv lawv nyob ze txaus kom nws ua haujlwm.

Kuv xav tias kuv rov sau dua thawj WiFiAnalyzer code tab sis tsis paub tias kuv hloov dab tsi. Nws yuav yog rau kuv cov zaub lossis qhov sib txawv ntawm ESP-07 thiab NodeMCU. Nyob rau hauv txhua rooj plaub, nws ua haujlwm tab sis cov credit mus rau tus pib.

Kuv tus lej yog txuas nrog: MTSWiFi.ino.

Kuv pom qee yam txog ESP-07 ntawm pawg thawj coj no. Cov kav hlau txais xov ceramic tau raug tshem tawm thiab muaj ib txoj hlua txuas rau lub kav hlau txais xov sab nraud. Cov kav hlau txais xov ceramic raug tshem tawm kom tsis muaj lub teeb liab tsis sib xws yog ob lub kav hlau txuas txuas tib lub sijhawm. Qhov jogged qee qhov kev nco. Kuv txoj kev npaj yuav muab lub kav hlau txais xov qhia rau nws kom kuv pom tau tias txhua lub teeb liab tau los qhov twg los.

Kuv tau nws txuas nrog lub kav hlau txais xov taw qhia, saib cov duab tom ntej.

Kuv xav tias tej zaum kuv tau muaj lub kav hlau txais xov txuas ntawm lub tswg.

Kuv tsis nco qab qhov tshwm sim. Kuv xav tias lawv yeej tsis tseem ceeb yog li kuv yuav cia li poob lub tswv yim.

Yog li kuv tau kawm qee yam hnub no. Kuv tau coj tus qauv los ntawm kuv LOG Wifi Analyzer (saib txuas nrog) thiab lwm qhov los ntawm kuv Lub Xov Tooj WiFi Ruaj Ntseg (saib txuas nrog)

Qhov sib txawv tseem ceeb yog NVR9ca3a93 ntawm Channel 14.

Tom qab pw ntawm no, Kuv muaj Eureka lub sijhawm, tau ua qee qhov kev tshawb fawb:

en.wikipedia.org/wiki/List_of_WLAN_channel…

Raws li cov lus qhia, North America tsis tso cai rau 12-14. Yog li ntawd piav qhia yog vim li cas kuv lub Smartphone tsis qhia nws thiab pom tseeb LOG WiFi tus kws tshuaj ntsuam ua.

Dab tsi nws tsis piav qhia yog dab tsi yog WiFi cov cuab yeej nrog SSID ntawm NVR9ca3a93?

Zoo, Kuv yuav ua qhov kev xav tias qhov no yog ESP-07 SSID hauv kuv LOG WiFi Analyzer.

TSWV YIM: Ib yam uas kuv paub yog ESP-03s uas kuv muaj AI_Thinker SSID. Raws li qhia hauv cov duab, qhov no yog ib qho ntawm kuv tus IP-Clock. Yog li kuv kwv yees tias ESP-07s muaj NVR ?? SSID.

Xaus: Txawm hais tias txhua qhov tsis paub thiab ua xyem xyav Qhov Kev Tshawb Fawb WiFi no ua haujlwm.
