• Baud tus nqi 115200
• Flash loj 4MB lossis 32mbit (nyob ntawm koj tus qauv)
• Flash hom QIO (lossis DIO, nyob ntawm koj tus qauv)
• 0x0000 rboot.bin ua
• 0x1000 blank_config.bin
• 0x2000 ledstrip.bin
• 40 MHz

Mac OS

Rau MacOS koj tuaj yeem siv cov cuab yeej flasher no

Chaw:

• Lwv flash - yog
• Baud tus nqi 115200
• Flash loj 4MB lossis 32mbit (nyob ntawm koj tus qauv)
• Flash hom QIO (lossis DIO, nyob ntawm koj tus qauv)
• Cov ntaub ntawv: ledstrip.bin
• 40 MHz

Manually nyem

Peb yuav tsum teeb tsa esptool.py ntawm peb Mac txhawm rau txhawm rau tuaj yeem nyem peb lub ESP module. Txhawm rau ua haujlwm nrog esptool.py, koj yuav xav tau Python 2.7, Python 3.4 lossis txhim kho Python tshiab ntawm koj lub system. Peb pom zoo kom siv Python version tshiab, yog li mus rau Python lub vev xaib thiab teeb tsa nws hauv koj lub computer.

Nrog Python teeb tsa, qhib Terminal qhov rai thiab teeb tsa qhov tseeb ruaj khov esptool.py tso nrog pip:

pip nruab esptool

Nco tseg: nrog qee qhov Python kev teeb tsa uas hais kom ua yuav tsis ua haujlwm thiab koj yuav tau txais qhov yuam kev. Yog tias qhov xwm txheej no, sim nruab esptool.py nrog:

pip3 nruab esptool sej -m pip nruab esptool pip2 nruab esptool

Tom qab teeb tsa, koj yuav muaj esptool.py teeb tsa rau hauv lub hauv paus Python executables directory thiab koj yuav tsum muaj peev xwm khiav nws nrog cov lus txib esptool.py. Hauv koj lub qhov rais Terminal, khiav cov lus txib hauv qab no:

esptool.py

Nrog esptool.py teeb tsa hauv koj lub khoos phis tawj, koj tuaj yeem yooj yim nyem koj li ESP8266 lub rooj tsavxwm nrog lub khoos phis tawj.

Thaum xub thawj koj yuav tsum rub peb daim ntawv rau hauv: rboot.bin thiab blank_config.bin thiab tso tawm zaum kawg. Lub rboot.bin muaj lub bootloader rau ESP8266 thiab blank_config.bin tsuas yog cov ntaub ntawv teeb tsa dawb thiab ledstrip.bin muaj cov firmware. Tam sim no txuas koj lub cuab yeej rau koj li FTDI adapter hauv hom nyem.

Daim iav txuas:

rboot.binblank_config.binledstrip.bin

Muab Ntaus rau Hauv Hom Flash

Kom pab tau ESP8266 firmware flashing GPIO0 tus pin yuav tsum rub qis thaum lub zog ntaus ntawv. Nrog kuv qhov kev cai PCB muaj lub pob, nodeMCU tseem muaj lub khawm nyem thiab Wemos nws puas siv tau USB. Hloov pauv, rau lub khau raj ib txwm, GPIO0 yuav tsum rub siab lossis ntab. Pib hauv FLASH MODE

Mus rau phau ntawv teev npe uas koj tau ua qhov twg koj tso rau yav dhau los rub tawm rboot.bin blank_config.bin cov ntaub ntawv (piv txwv li rub tawm)

Qhib Terminal app. Nyem rau Finder icon hauv koj cov khoom. Nyem mus. Nyem Utilities. Ob-nias Terminal. Hloov mus rau phau ntawv teev npe rub tawm.

Koj yuav xav tau USB TTL adapter txuas rau ESP8266. Yog tias koj siv Wemos D1 Mini tsuas yog xav tau yog microUSB cable, Wemos muaj TTL adapter ua-hauv.

cd cov downloads

Nco tseg: Yog tias koj siv lwm lub tsev qiv ntawv khaws cia peb lub.bin cov ntaub ntawv, mus rau hauv lub tsev qiv ntawv ntawd siv 'cd` hais kom ua:

Siv esptool.py los nyem koj lub cuab yeej. Ua ntej peb yuav tsum lwv lub flash:

esptool.py -p / dev / erase_flash

Feem ntau, koj li ESPPort yuav yog ib yam zoo li /dev /cu.usbserial-`xxxxxx`. Tom qab ntawd, teeb tsa koj lub cuab yeej hauv hom nyem dua, thiab nyem qhov firmware tshiab:

esptool.py -p /dev/cu.wchusbserial1420 --baud 115200 write_flash -fs 32m -fm dio -ff 40m 0x0 rboot.bin 0x1000 blank_config.bin 0x2000 ledstrip.bin

Kauj ruam 2: Wi-nkaus thiab HomeKit Teeb

Teeb Wi-nkaus

Koj yuav tsum teeb tsa wifi network ua ntej ntxiv cov khoom siv rau HomeKit. Txhawm rau teeb tsa Wi-Fi chaw, lub cuab yeej tsim nws tus kheej Wi-nkaus hauv AP hom. Koj yuav tsum txuas rau nws txhawm rau teeb tsa koj li Wi-nkaus network. Cias coj koj lub cuab yeej iOS, mus rau Chaw-> Wi-nkaus, thiab tshawb rau SSID hu ua HomeKid- ua raws los ntawm tus qauv MAC chaw nyob thiab txuas rau nws. Rau qhov laj thawj nyab xeeb AP yog tus tiv thaiv tus password! Default AP password: 12345678

Tos ob peb feeb kom txog thaum lub vev xaib tshwm los qhia koj txhua Wi-nkaus tes hauj lwm uas lub cuab yeej tau pom. Xaiv koj li, thiab sau tus password! Tom qab ntawd koj tuaj yeem ntxiv tus lej pes tsawg ntawm LEDs hauv koj daim kab xev LED! Sau tus lej ntawm 1 txog 500! Tom qab ntawv nyem khawm Koom! Tus qauv yuav sim txuas lub Wi-nkaus network uas tau xaiv, qhov no yuav siv ob peb feeb.
