Qala ka EK057
Seo U se Hlokang
Ho nts'etsapele lits'ebetso tsa mojule oa EK057 o hloka:
- 1 x EK057 likarolo
- 1 x Boto ea tlhahlobo ea Espressif RF
- 1 x USB-to-Serial board
- 1 x Thapo ea Micro-USB
- 1 x PC e sebelisang Linux
Tataisong ena ea basebelisi, re nka sistimi ea ts'ebetso ea Linux joalo ka example. Bakeng sa tlhaiso-leseling e batsi mabapi le tlhophiso ea Windows le macOS, ka kopo sheba Tataiso ea Lenaneo la ESP-IDF.
Khokahano ea Hardware
- Solder EK057 module ho boto ea tlhahlobo ea RF joalo ka ha ho bonts'itsoe ho Setšoantšo sa 1.
- Hokela boto ea tlhahlobo ea RF ho boto ea USB-to-Serial ka TXD, RXD, le GND.
- Hokela boto ea USB-to-Serial ho PC.
- Hokela boto ea tlhahlobo ea RF ho PC kapa adaptara ea matla ho nolofalletsa phepelo ea matla a 5 V, ka thapo ea Micro-USB.
- Nakong ea ho jarolla, hokela IO0 ho GND ka jumper. Ebe, bula "ON" boto ea tlhahlobo.
- Khoasolla firmware ho Flash. Ho fumana lintlha, sheba likarolo tse ka tlase.
- Kamora ho jarolla, tlosa jumper ho IO0 le GND.
- Matlafatsa boto ea tlhahlobo ea RF hape. EK057 e tla fetohela ho mokhoa oa ho sebetsa. Chip e tla bala mananeo ho tloha ho flash ha e qala.
Hlokomela:
IO0 e phahame ka hare ho naha. Haeba IO0 e setetsoe ho hula, ho khethoa mokhoa oa Boot. Haeba phini ena e hula fatše kapa e tlohetsoe e phaphametse, ho tla khethoa mokhoa oa ho jarolla. Bakeng sa tlhaiso-leseling e batsi ka EK057, ka kopo sheba ho EK057 Datasheet.
Theha Tikoloho ea Ntlafatso
Espressif IoT Development Framework (ESP-IDF ka bokhutšoane) ke moralo oa ho ntlafatsa lits'ebetso tse thehiloeng ho Espressif ESP32. Basebelisi ba ka etsa lits'ebetso ka ESP32 ho Windows/Linux/macOS ho latela ESP-IDF. Mona re nka sistimi ea ts'ebetso ea Linux joalo ka example.
Kenya lintho tse hlokahalang
Ho kopanya le ESP-IDF o hloka ho fumana liphutheloana tse latelang:
- CentOS 7:
sudo yum kenya git wget flex bison gperf python cmake ninja−build ccache dfu-util - Ubuntu le Debian (taelo e le 'ngoe e aroloa ka mela e' meli):
sudo apt-get install git wget flex bison gperf python python−pip python−setuptools cmake ninja -build ccache libffi -dev libssl -dev dfu−util - Arch:
sudo pacman −S −−e hlokehang gcc git etsa flex bison gperf python−pip cmake ninja ccache dfu−util - Hlokomela:
- Tataiso ena e sebelisa directory ~/esp ho Linux joalo ka foldara ea ho kenya ESP-IDF.
- Hopola hore ESP-IDF ha e tšehetse libaka litseleng.
Fumana ESP-IDF
Ho aha lits'ebetso tsa mojule oa EK057, o hloka lilaebrari tsa software tse fanoeng ke Espressif sebakeng sa polokelo ea ESP-IDF.
Ho fumana ESP-IDF, theha bukana ea ho kenya (~/esp) ho khoasolla ESP-IDF le ho kopanya polokelo ka 'git clone':
- mkdir −p ~/esp
- cd ~/esp
- git clone −−recursive https://github.com/espressif/esp−idf. git
ESP-IDF e tla khoasolloa ho ~/esp/esp-idf. Sheba Liphetolelo tsa ESP-IDF bakeng sa tlhahisoleseding mabapi le hore na ke mofuta ofe oa ESP-IDF o ka sebelisoang boemong bo itseng.
Hlophisa Lisebelisoa
Ntle le ESP-IDF, u boetse u hloka ho kenya lisebelisoa tse sebelisoang ke ESP-IDF, tse kang compiler, debugger, Python packages, joalo-joalo ESP-IDF e fana ka mongolo o bitsoang 'install.sh' ho thusa ho theha lisebelisoa. ka nako e le 'ngoe.
cd ~/esp/esp-idf
Theha Liphetoho tsa Tikoloho
Lisebelisoa tse kentsoeng ha li e-so kenyellelitsoe ho phapano ea tikoloho ea PATH. Ho etsa hore lisebelisoa li sebelisoe ho tsoa moleng oa taelo, mefuta e meng ea tikoloho e tlameha ho hlophisoa. ESP-IDF e fana ka mongolo o mong oa 'export.sh' o etsang joalo. Ho theminale moo u tla sebelisa ESP-IDF, matha: kenya .sh. $HOME/esp/esp−idf/export.sh
Joale tsohle li se li lokile, o ka theha projeke ea hau ea pele mojuleng oa EK057.
Theha Morero oa Hao oa Pele
Qala Morero
Joale u se u loketse ho lokisa kopo ea hau ea mojule oa EK057. O ka qala ka morero oa ho qala/hello_world ho tsoa ho exampLes directory ho ESP-IDF.
Kopitsa ho qala/hello_world ho ~/esp directory:
cd ~/esp
cp −r $IDF_PATH/examples/get−start/hello_world .
Ho na le mefuta e mengata ea example merero ho exampLes directory ho ESP-IDF. O ka kopitsa morero ofe kapa ofe ka tsela e ts'oanang le e hlahisitsoeng ka holimo mme oa e tsamaisa. Hape hoa khoneha ho haha examps in-place, ntle le ho li kopitsa pele.
Kopanya Sesebelisoa sa Hau
Joale hokela mojule oa hau oa EK057 komporong 'me u hlahlobe hore na mojule oa hau o bonahala tlas'a boema-kepe bofe ba serial. Likou tsa Se-rial ho Linux li qala ka '/dev/tty' ka mabitso a tsona. Matha taelo e ka tlase ka makhetlo a mabeli, pele ka boto e sa kengoa, ebe e kenngoa. Boema-kepe bo hlahang lekhetlo la bobeli ke bona boo u bo hlokang:

Hlokomela:
Boloka lebitso la boema-kepe le le haufi kaha u tla le hloka mehatong e latelang.
Hlophisa
Tsamaea ho buka ea hau ea 'hello_world' ho tloha Mohato oa 2.4.1. Qala Morero, beha chip ea ESP32 joalo ka sepheo 'me u tsamaise sesebelisoa sa tlhophiso ea projeke 'menu config'.
- cd ~/esp/hello_world
- IDF .py set−target esp32
- IDF .py menuconfig
Ho beha sepheo ka 'idf.py set-target esp32' ho lokela ho etsoa hang, ka mor'a ho bula morero o mocha. Haeba projeke e na le meaho le litlhophiso tse seng li ntse li le teng, li tla hlakoloa le ho qalisoa. Sepheo se ka bolokoa ka ho feto-fetoha ha tikoloho ho tlola mohato ona ho hang. Sheba Ho Khetha Sepheo bakeng sa boitsebiso bo eketsehileng. Haeba mehato e fetileng e entsoe ka nepo, menu e latelang e tla hlaha:
Setšoantšo sa 2: Tlhophiso ea Morero - Fesetere ea Lehae
Mebala ea menu e ka fapana ho terminal ea hau. O ka fetola ponahalo ka khetho ea '--style'. Ka kopo, matha 'idf.py menuconfig --help'bakeng sa lintlha tse ling.
Haha Morero
Theha morero ka ho tsamaisa:
