Installation thiab teeb
Yog hais tias koj yog ib tug beginner, xa mus rau lub file "Tau Pib Nrog Arduino" txhawm rau txhim kho ESP32 txhim kho pawg tsav tsheb thiab Arduino IDE, nrog rau ESP32 kev txhim kho ib puag ncig.
Uploading Test Code
Rub tawm cov lej xeem tau muab rau ESP32 pawg thawj coj txhim kho. Cov cai yuav tso cai rau ESP32 luam theej duab rau WIFI network nyob ze thiab luam tawm lawv cov npe thiab teeb liab zog ntawm qhov chaw nres nkoj serial txhua 5 vib nas this.
#include WiFi.h void setup() { Serial.begin(115200); // Teem WiFi rau hom chaw nres tsheb thiab txiav tawm ntawm AP yog tias nws tau txuas yav dhau los WiFi.mode(WIFI_STA); WiFi.disconnect(); ncua (100); Serial.println("Kev teeb tsa tiav"); } void loop() { Serial.println("Scan start"); // WiFi.scanNetworks yuav rov qab cov xov tooj ntawm tes pom int n = WiFi.scanNetworks(); Serial.println("Scan ua tiav"); yog (n == 0) { Serial.println("No networks found"); } else { Serial.print(n); Serial.println("networks found"); rau (int i = 0; i < n; ++i) { // Sau SSID thiab RSSI rau txhua lub network pom Serial.print(i + 1); Serial.print(": "); Serial.print(WiFi.SSID(i)); Serial.print("("); Serial.print(WiFi.RSSI(i)); Serial.print(")"); Serial.println((WiFi.encryptionType(i) == WIFI_AUTH_OPEN) ? ":*" : ""); ncua (10); } } Serial.println(); // Tos me ntsis ua ntej luam theej dua ncua (5000); }
Viewntawm Test Results
Tom qab uploading cov cai, qhib lub serial chaw nres nkoj rau view WIFI networks pom los ntawm ESP32.
Cov lus nug nquag nug (FAQ)
Q: Kuv yuav ua li cas yog tias kuv ntsib kev cuam tshuam thaum siv ESP32 Development Board?
A: Xyuas kom meej tias lub cuab yeej ua haujlwm nrog qhov tsawg kawg nkaus ntawm 20cm ntawm lub tshuab hluav taws xob thiab koj lub cev kom ua raws li FCC cov kev txwv hluav taws xob.
Kev piav qhia
- Qhov no yog universal WIFI ntxiv rau Bluetooth txhim kho pawg thawj coj saib raws li ESP32, kev koom ua ke nrog ESP32-WOROOM-32 module thiab sib xws nrog Arduino.
- Nws muaj lub tsev sensor, kev kub ceev SDIO / SPI, UART, I2S thiab I2C. Tsis tas li ntawd, nruab nrog RTOS kev ua haujlwm pub dawb, uas yog qhov tsim nyog rau Internet ntawm cov khoom thiab cov tsev ntse.

Yog hais tias koj yog ib tug beginner, thov mus saib lub file Pib nrog Arduino rau nruab ESP32 txhim kho pawg tsav tsheb thiab Arduino IDE nrog rau ESP32 kev txhim kho ib puag ncig.
Xeem Code
Tom qab uploading tus lej, ESP32 yuav pom nyob ze WIFI thiab luam lub npe thiab teeb liab lub zog ntawm qhov chaw nres nkoj serial txhua 5s.
Kev Xeem
Tom qab uploading cov cai, qhib qhov chaw nres nkoj thiab peb tuaj yeem pom wifi pom los ntawm ESP32.
FCC Lus Ceeb Toom
Cov cuab yeej no tau raug sim thiab pom tias ua raws li cov kev txwv rau Class B cov cuab yeej digital, raws li Tshooj 15 ntawm FCC Cov Cai. Cov kev txwv no yog tsim los muab kev tiv thaiv tsim nyog tiv thaiv kev cuam tshuam tsis zoo hauv kev teeb tsa hauv tsev. Cov cuab yeej no tsim, siv thiab tuaj yeem tawg lub zog ntawm xov tooj cua thiab, yog tias tsis tau nruab thiab siv raws li cov lus qhia, yuav ua rau muaj kev cuam tshuam rau kev sib txuas lus hauv xov tooj cua. Txawm li cas los xij, tsis muaj kev lees paub tias kev cuam tshuam yuav tsis tshwm sim hauv ib qho kev teeb tsa tshwj xeeb. Yog tias cov cuab yeej no ua rau muaj kev cuam tshuam tsis zoo rau lub xov tooj cua lossis TV txais tos, uas tuaj yeem txiav txim siab los ntawm kev tig cov cuab yeej tawm thiab qhib, tus neeg siv tau raug txhawb kom sim kho qhov cuam tshuam los ntawm ib lossis ntau qhov kev ntsuas hauv qab no:
- Reorient los yog tshem tawm cov kav hlau txais xov.
- Ua kom muaj kev sib cais ntawm cov khoom siv thiab lub receiver.
- Txuas cov cuab yeej mus rau lub qhov hluav taws xob ntawm ib lub voj voog sib txawv ntawm qhov uas lub receiver txuas nrog.
- Nrog rau tus neeg muag khoom lossis tus kws tshaj lij xov tooj cua / TV rau kev pab.
Ceev faj:
Ib qho kev hloov pauv lossis hloov kho rau lub cuab yeej no tsis pom zoo los ntawm cov chaw tsim khoom tuaj yeem ua rau koj txoj cai ua haujlwm cov cuab yeej no tsis muaj tseeb.
Cov cuab yeej no ua raws li Tshooj 15 ntawm FCC Cov Cai. Kev ua haujlwm yog ua raws li ob yam hauv qab no:
- Cov cuab yeej no yuav tsis ua teeb meem cuam tshuam, thiab
- Cov cuab yeej no yuav tsum lees txais ib qho kev cuam tshuam tau txais, suav nrog kev cuam tshuam uas yuav ua rau kev ua haujlwm tsis xav tau.
Cov cuab yeej tau raug soj ntsuam kom ua tau raws li qhov yuav tsum tau muaj kev cuam tshuam RF dav dav Cov cuab yeej no ua raws li FCC cov kev txwv tsis pub muaj hluav taws xob tau teeb tsa rau qhov chaw tsis muaj kev tswj hwm. Cov cuab yeej no yuav tsum tau nruab thiab ua haujlwm nrog qhov tsawg kawg nkaus ntawm 20cm ntawm lub tshuab hluav taws xob thiab koj lub cev.
