Fa'atuina So'oga Fa'asologa ma ESP32-S2-MINI-1 & ESP32-S2-MINI-1U

O lenei vaega o loʻo tuʻuina atu ai le taʻiala ile faʻavaeina o fesoʻotaʻiga i le va o le ESP32-S2MINI-1 ma le ESP32-S2-MINI-1U ma le PC.

4.1. Faʻafesoʻotaʻi le ESP32-S2-MINI-1 ma le ESP32-S2-MINI-1U ile PC

Faʻafesoʻotaʻi le laupapa ESP32 i le PC e faʻaaoga ai le USB cable. Afai e le faʻapipiʻi le avetaavale masini
otometi, fa'ailoa le USB i le va'aiga fa'aliliu fa'asologa i luga o lau laupapa ESP32 (po'o le dongle liliu mai fafo), su'e ta'avale i luga o le initaneti, ma fa'apipi'i.
Lalo o fesoʻotaʻiga i avetaavale mo ESP32-S2-MINI-1 ma ESP32-S2-MINI-1U laupapa na gaosia e Espressif:
CP210x USB i UART Bridge VCP Avetaavale
FTDI Virtual COM Port Avetaavale
O avetaavale o loʻo i luga e masani lava mo faʻamatalaga. I lalo o tulaga masani, e tatau ona faʻapipiʻi avetaʻavale ma se faiga faʻaogaina ma faʻapipiʻi faʻapipiʻi pe a faʻafesoʻotaʻi se tasi o laupapa lisi i le PC.

4.2. Siaki le Taulaga ile Windows
Siaki le lisi o pusa COM faʻamaonia i le Windows Device Manager. Aveese le fesoʻotaʻiga ESP32S2 ma faʻafesoʻotaʻi i tua, e faʻamaonia po o le fea uafu e mou atu mai le lisi ona toe faʻaalia lea.

Ata 4-1. USB i UART alalaupapa o le ESP32-S2 Board i Windows Device Manager

Ata 4-2. Lua USB Serial Ports o le ESP32-S2 Board i Windows Device Manager

4.3. Siaki Port i Linux ma macOS
Ina ia siaki le igoa o le masini mo le laina telefoni o lau laupapa ESP32-S2 (poʻo le dongle liliu mai fafo), faʻatino lenei poloaiga faʻalua, muamua ma le laupapa / dongle ua tatala, ona faʻapipiʻi lea i totonu. e te manaʻomia: Linux

MacOS
ls /dev/cu.*

4.4. Faʻaopoopo le tagata faʻaoga e faʻafesoʻotaʻi i luga o Linux
O le tagata o lo'o fa'aoga i le taimi nei e tatau ona faitau ma tusitusi le avanoa i le laina telefoni i luga ole USB. I luga o le tele o faʻasalalauga Linux, e faia lenei mea e ala i le faʻaopoopoina o le tagata faʻaoga i le faʻasalalauga vaega ma le faʻatonuga lea: sudo usermod -a -G dialout $USER i Arch Linux e faia lea i le faʻaopoopoina o le tagata faʻaoga i le uucp vaega ma le poloaiga lenei: sudo usermod - a -G uucp $USER
Ia mautinoa e te toe saini ina ia mafai ai ona faitau ma tusi faatagaga mo le laina telefoni.

4.5. Fa'amaonia So'oga Fa'asologa
Ia fa'amaonia nei o lo'o fa'agaioi le so'oga fa'asologa. E mafai ona e faia lenei mea e ala i le fa'aogaina o se polokalame fa'asologa fa'asologa. I lenei exampmatou te fa'aogaina le PuTTY SSH Client o lo'o avanoa mo Windows ma Linux. E mafai ona e fa'aogaina isi polokalame fa'asologa ma fa'atulaga laina feso'ota'iga pei o lalo.
Fa'ato'a fa'auma, seti fa'ailoga uafu fa'asologa, pa'u fua = 115200, fa'amaumauga fa'amaumauga = 8, taofi pa = 1, ma parity = N. O lo'o i lalo o fa'amatalaga.ampo ata mata o le setiina o le taulaga ma ia fa'asalalauga fa'asalalau (i se faapuupuuga fa'amatalaina o le 115200-8-1-N) i luga o Windows ma Linux. Manatua e filifili tonu le laina laina tutusa na e faʻaalia i laasaga i luga.

Ata 4-3. Fa'atulagaina Feso'ota'iga Fa'asologa i PuTTY i luga ole Windows

Ata 4-4. Faʻatulagaina Fesoʻotaʻiga Faʻasalalau ile PuTTY ile Linux

Ona tatala lea o le port serial i le terminal ma siaki, pe a e vaʻai i soʻo se ogalaau lolomi e ESP32-S2.
O mea o lo'o i totonu ole a fa'alagolago ile talosaga e uta ile ESP32-S2.

Fa'amatalaga:

• Mo nisi o feso'ota'iga uaea tau telefoni, o pine RTS & DTR e mana'omia ona fa'agata i le polokalame fa'amau a'o le'i fa'a'ave'a le ESP32-S2 ma fa'atupuina fa'asologa. E fa'alagolago lea i meafaigaluega lava ia, o le tele o laupapa atina'e (e aofia uma ai laupapa Espressif) e leai se fa'afitauli. O lo'o iai le fa'afitauli pe a fa'apipi'i sa'o le RTS & DTR i pine EN & GPIO0. Va'ai le esptool pepa mo nisi fa'amatalaga.
• Tapuni laina laina pe a uma ona faʻamaonia o loʻo galue fesoʻotaʻiga. I le isi laasaga o le a matou faʻaogaina se isi talosaga e faʻapipiʻi ai se masini fou i le ESP32-S2. O lenei talosaga o le a le mafai ona maua le laina telefoni a'o tatala i le laina telefoni.

Fa'atonu

Ulufale hello_world directory ma ta'e le menuconfig.
Linux ma MacOS
cd ~/esp/hello_world
idf.py -DIDF_TARGET=esp32s2beta menuconfig
Atonu e te manaʻomia le taʻavale python2 idf.py ile Python 3.0.
Pupuni
cd %userprofile%\esp\hello_world
idf.py -DIDF_TARGET=esp32s2beta menuconfig
O le Python 2.7 installer o le a taumafai e faʻapipiʻi Windows e faʻafesoʻotaʻi se faila .py ma
Python 2. Afai o isi polokalame (e pei o Visual Studio Python meafaigaluega) sa feso'ota'i ma isi fa'aliliuga o le Python, idf.py atonu e le lelei le galue (o le a tatala le faila ile Visual Studio). I lenei tulaga, e mafai ona e filifili e tamoe C:\Python27\python idf.py i taimi uma, pe suia le Windows .py fa'apipi'i faila.

Fausia ma Flash

Ole taimi nei e mafai ona e fausia ma fa'aola le talosaga. tamoe:
idf.py fausia
O lenei mea o le a tuʻufaʻatasia le talosaga ma vaega uma o le ESP-IDF, faʻatupuina le bootloader,
laulau vaeluaga, ma fa'aoga fa'ameamea, ma fa'aola nei ta'i i lau laupapa ESP32-S2.
