Vim li cas? backup ntawm thawj firmware yog qhov tseem ceeb.

simplest ans yog = thawj yog thawj

Hauv qhov kev qhia no kuv yuav qhia koj yuav ua li cas backup thawj firmware ntawm esp8266ex.

ESP8266EX yog tus nqi qis Wi-nkaus microchip nrog tag nrho TCP/IP pawg thiab microcontroller muaj peev xwm tsim los ntawm cov khw Espressif Systems hauv Shanghai, Suav.

Kho vajtse

1. ESP8266EX lossis ESP8266-01

2. FTDI Module uas txhawb 3.3 v Cov Lus Tso Tawm

3. Cov qhob cij

4. thiab qee tus Poj Niam rau Poj Niam jumper hlau

Kuv tsis tawm tswv yim rau Arduino. nws ua rau muaj teeb meem ntau

Kauj ruam 2: Yuav tsum tau Software

1. Python 2 lossis Python 3 nws nyob ntawm koj

Thiab tsis txhob hnov qab teeb tsa (Python Serial Library) kom paub ntau ntxiv thiab txheej txheem teeb tsa

2.esptool

3. thaum kawg koj yuav xav tau cov lus txib lossis lub davhlau ya nyob twg

thiab Software ib feem tau ua tiav

FTDI Kev Sib Txuas …………………. ESP8266EX Kev Sib Txuas

  1. FTDI GND ………………………………………. ESP GND + ESP GPIO0
  2. FTDI RX ……………………………………………….. ESP TX
  3. FTDI TX ……………………………………………….. ESP RX
  4. FTDI VCC ……………………………………….. ESP CH-PD + ESP VCC

Ib feem ntawm kev sib txuas tau ua tiav tam sim no nws yog lub sijhawm rau thaub qab

  1. theej cov esptool rau (C:/) Cov npe
  2. Qhib koj qhov hais kom ua
  3. tam sim no ua raws cov lus txib

cd / cov

cd esptool

Kev teeb tsa Esptool

setup.py nruab

TSEEM CEEB kom raug teeb tsa qhov loj me thiab flash hom qhov tseem ceeb raws li koj lub cuab yeej

esptool.py --port COMx flash_id

Firmware thaub qab

esptool.py --port COMx read_flash 0x00000 0x400000 image.bin

Qee cov lus txib ntxiv:

Lwv firmware

esptool.py --port COMx lwv_flash

Rub tawm firmware

esptool.py --port COMx write_flash -fs 4MB -fm dio 0x0 image.binHloov tus nqi x rau koj qhov chaw nres nkoj COM x = Chaw Naj Npawb…. Piv txwv: COM15, COM12
