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.
Kauj ruam 1: Yuav tsum kho vajtse
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
Kauj Ruam 3: Kev Kho Vajtse Txuas
FTDI Kev Sib Txuas …………………. ESP8266EX Kev Sib Txuas
- FTDI GND ………………………………………. ESP GND + ESP GPIO0
- FTDI RX ……………………………………………….. ESP TX
- FTDI TX ……………………………………………….. ESP RX
- 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
Kauj ruam 4: Tam sim no hais kom ua ntu ntu
- theej cov esptool rau (C:/) Cov npe
- Qhib koj qhov hais kom ua
- 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
