Nqe lus piav qhia:

Cov Qauv no yog USB adapter /programmer rau ESP8266 cov qauv ntawm hom ESP-01 lossis ESP-01S. Nws tau yooj yim haum nrog 2x4P 2.54mm poj niam lub taub hau los ntsaws ESP01. Tsis tas li nws tawg tawm txhua tus pin ntawm ESP-01 ntawm 2x4P 2.54mm txiv neej lub taub hau, yog li nws yooj yim heev rau cov neeg siv los daws qhov ESP8266.

Tus qauv yog ua raws USB-UART CP2104 uas yog sib xws nrog txhua lub platform. Onboard nrog ESP8266 tsis siv neeg rub tawm Circuit. Nws yog qhov yooj yim heev rau cov neeg siv rub tawm ESP-01/01S program, hloov kho firmware, txuas debugging thiab lwm yam. Nws txhawb nqa ntau yam software xws li Arduino IDE, ESP8266 Flasher thiab Lexin FLASH_DOWNLOAD_TOOLS.

Kev qhia tshwj xeeb:

• USB hom A interface.
• Ib 2x4P 2.54mm poj niam lub taub hau
• Ib 2x4P 2.54mm txiv neej lub taub hau
• Ua haujlwm Volatge: 3.3V

Kauj Ruam 1: Cov Npe Khoom

Cov duab txuas nrog qhia pom cov khoom siv xav tau Hauv qhov kev qhia no:

1. ESP8266 Flasher thiab Programmer
2. ESP8266 Wifi Serial Transceiver Module
3. Jumper hlau.

Kauj Ruam 2: Kev Kho Vajtse

Daim duab saum toj no qhia txog kev sib txuas ntawm ESP8266 Flasher thiab Programmer thiab ESP8266 Wifi Serial Transceiver Module los ntawm kev siv jumper xaim.

Kauj Ruam 3: Rub Cov Ntawv

Rub tus tsav tsheb rau ESP8266 Flasher thiab Programmer

Rub tawm firmware hauv ESP8266 Flash Tool nplaub tshev.

Thiab nruab tus tsav tsheb.

Kauj Ruam 4: Txhim Kho Firmware

Qhov rai (AT Firmware)

1. Tom qab rub tawm Firmware Flasher file. Extract nws. Nkag mus rau daim nplaub tshev, mus rau install_firmware> window.
2. Qhib ESP_DOWNLOAD_TOOL_V2.4.exe.
3. Xaiv qhov chaw nres nkoj COM ESP8266 Flasher thiab Programmer + ESP8266 Wifi Serial Transceiver module txuas rau. Teem BAUDRATE rau 115200.
4. Nco ntsoov ESP8266 Wifi Serial Transceiver module nyob hauv FLASH hom (Xa mus rau Kauj Ruam 2 thawj daim duab rau kho vajtse teeb tsa)
5. Nyem START txhawm rau teeb tsa lub firmware.

• bin / boot_v1.2.bin 0x00000
• bin / user1.4096.new.4.bin 0x01000
• bin / blank.bin 0x7e000
• bin / user2.4096.new.4.bin 0x81000
• bin / esp_init_data_default.bin 0x3fc000
• bin / blank.bin 0x3fe000

Kauj ruam 5: AT Hais kom ua hauv Arduino

1. Txuas lub xov hlau txuas los ntawm ESP8266 Flasher thiab Programmer (Xa mus rau kauj ruam 2 daim duab thib ob)
2. Qhib koj Arduino ces nyem qhov saib ua ntej.
3. Nias lub pob pib dua kom paub tseeb tias esp8266 txuas nrog ntawm tus saib xyuas.
4. Thov ua raws qhov kev teeb tsa saib xyuas qhov tseeb (Xa daim duab saum toj no)
5. Tom qab ntawv sau AT thiab xa nws, nws yuav teb tias yog
6. Yog xav paub ntau ntxiv txog AT Command, nyem qhov txuas no kom paub ntau ntxiv txog AT Command

Txhawm rau hloov baudrate siv AT Command:

AT+ UART_DEF = 19200, 8, 1, 0, 0

Piv txwv li 9600 baudrate / 8 cov ntaub ntawv khoom / 1 nres cov khoom thiab tsis muaj qhov sib npaug thiab tswj kev ntws AT+UART_DEF = 9600, 8, 1, 0, 0

qhov hais kom ua AT+CIOBAUD = 9600 nws yuav hloov pauv baudrate ib ntus
