Zvaunoda
Kugadzira zvikumbiro zveESP32-C3-WROOM-02U module yaunoda:

• 1 x ESP32-C3-WROOM-02U module
• 1 x Espressif RF yekuongorora bhodhi
• 1 x USB-ku-Serial bhodhi
• 1 x Micro-USB tambo
• 1 x PC inoshandisa Linux
  Mugwaro iri remushandisi, tinotora Linux inoshanda sisitimu seye example. Kuti uwane rumwe ruzivo nezve kumisikidzwa paWindows uye macOS, ndapota tarisa ESP-IDF Programming Guide.

Hardware Connection

1. Solder iyo ESP32-C3-WROOM-02U module kune iyo RF yekuyedza bhodhi sezvakaratidzwa mumufananidzo 2.
   
2. Batanidza iyo RF yekuyedza bhodhi kune USB-ku-Serial bhodhi kuburikidza neTXD, RXD, uye GND.
3. Batanidza USB-ku-Serial board kuPC.
4. Batanidza RF yekuyedza bhodhi kuPC kana dhiraivha yemagetsi kugonesa 5 V magetsi, kuburikidza neMicro-USB tambo.
5. Panguva yekurodha, batanidza IO9 kuGND kuburikidza nejumper, uye dhonza kumusoro IO2 neIO8. Wobva wabatidza "BATIA" bhodhi rekuyedza.
6. Dhawunirodha firmware muflash. Kuti uwane rumwe ruzivo, ona zvikamu pazasi.
7. Mushure mekudhawunirodha, bvisa jumper paIO0 neGND, uye jumper waya yekukwevera kumusoro IO8.
8. Simba kumusoro kweRF yekuongorora bhodhi zvakare. ESP32-C3-WROOM-02U ichachinja kune kushanda mode. Iyo chip ichaverenga zvirongwa kubva kuflash pakutanga.

Cherechedza:
IO9 ndeyemukati logic yakakwira. Kana IO9 yakadhonzwa pasi, uye IO2 neIO8 yakadhonzwa kumusoro, iyo Boot mode inosarudzwa. Mune zvimwe zviitiko, iyo Download mode inosarudzwa. Kuti uwane rumwe ruzivo nezve ESP32-C3-WROOM-02U, ndapota tarisa kuESP32-C3-WROOM-02 & ESP32-C3-WROOM-02U Datasheet.

Gadzira Development Environment
Iyo Espressif IoT Development Framework (ESP-IDF kwenguva pfupi) igadziriro yekugadzira zvikumbiro zvichibva pamachipisi eEspressif. Vashandisi vanogona kugadzira maapplication neESP machipi muWindows/Linux/macOS zvichibva paESP-IDF. Pano isu tinotora Linux inoshanda sisitimu seye example.

Isai Zvokutanga
Kuti uunganidze neESP-IDF unofanirwa kuwana mapakeji anotevera:

• CentOS 7:
  1 sudo yum kuisa git wget flex bison gperf python cmake ninja-kuvaka ccache dfuutil
  Ubuntu uye Debian (murairo mumwe unotsemuka kuita mitsetse miviri):
  1 sudo apt-tora kuisa git wget flex bison gperf python python-pip python kuseta maturusi
• cmake
  2 ninja-kuvaka ccache libffi-dev libssl-dev dfu-util Arch:
  1 sudo pacman -S -inoda gcc git ita flex bison gperf python-pip cmake ninja ccache dfu-util

Cherechedza

• Gwaro iri rinoshandisa dhairekitori ~/esp paLinux senge yekuisa folda yeESP-IDF.
• Ramba uchifunga kuti ESP-IDF haitsigire nzvimbo munzira.

 Tora ESPDF
Kuvaka zvikumbiro zveESP32-C3-WROOM-02U module, unoda maraibhurari esoftware anopihwa neEspressif muESP-IDF repository.
Kuti uwane ESP-IDF, gadzira dhairekitori rekuisa (~/esp) kurodha ESP-IDF kune uye kutevedzera repository ne 'git clone':

1. mkdir -p ~/esp
2. cd ~/esp
3. git clone -inodzokorora https://github.com/espressif/esp-idf.git

ESP-IDF ichatorwa mu ~/esp/esp-idf. Bvunza ESP-IDF Versions kuti uwane ruzivo rwekuti ndeipi ESP-IDF vhezheni yekushandisa mumamiriro akapihwa.

Gadzirisa Zvishandiso
Kunze kweESP-IDF, unofanirawo kuisa maturusi anoshandiswa neESP-IDF, senge compiler, debugger, Python packages, etc. ESP-IDF inopa chinyorwa chinonzi 'install.sh' kuti chibatsire kugadzirisa maturusi. mune imwe kuenda.

1. cd ~/esp/esp-idf
2. ./install.sh

Gadzirisa Environment Variables
Zvishandiso zvakaiswa hazvisati zvawedzerwa kune PATH nharaunda inosiyana. Kuita kuti maturusi ashandiswe kubva kumutsara wekuraira, mamwe mamiriro enzvimbo anofanirwa kusetwa. ESP-IDF inopa imwe script 'export.sh' inoita izvozvo. Mune iyo terminal yauchazoshandisa ESP-IDF, mhanya:

1. $HOME/esp/esp-idf/export.sh Iye zvino zvese zvagadzirira, unogona kuvaka chirongwa chako chekutanga paESP32-C3-WROOM-02U module.

 Gadzira Yako Yekutanga Project

Kutanga chirongwa
Iye zvino wagadzirira kugadzirira chikumbiro chako cheESP32-C3-WROOM-02U module. Unogona kutanga nekutanga/hello_world chirongwa kubva kune exampLes directory muESP-IDF.

Kopa kutanga/hello_world ku ~/esp dhairekitori:
1 cd ~/esp
2 cp -r $IDF_PATH/examples/get-start/hello_world .
Kune huwandu hwe example mapurojekiti mune exampLes directory muESP-IDF. Unogona kukopa chero purojekiti nenzira imwechete seyakaratidzwa pamusoro uye woimhanyisa. Zvinogoneka zvakare kugadzira examps in-place, pasina kutanga waakopa.

 Unganidza Mudziyo Wako
Zvino batanidza yako ESP32-C3-WROOM-02U module kune komputa uye tarisa pasi peiyo serial port iyo module inoonekwa. Serial ports muLinux anotanga ne '/ dev/tty' mumazita avo. Mhanya murairo uri pasi apa kaviri, kutanga nebhodhi risina kuvharwa, uye nekubatanidzwa. Chiteshi chinooneka kechipiri ndicho chaunoda:

Configure
Enda kune yako 'hello_world' dhairekitori kubva Danho 2.4.1. Tanga Project, isa ESP32-C3 sechinangwa uye mhanyisa purojekiti yekumisikidza utility 'menuconfig'.

1. cd ~/esp/hello_world
2. idf.py set-target esp32c3
3. idf.py menuconfig

Kuisa chinangwa ne 'idf.py set-target esp32c3' kunofanira kuitwa kamwe chete, mushure mekuvhura chirongwa chitsva. Kana iyo purojekiti iine zvimwe zviripo zvekuvaka uye zvigadziriso, zvinocheneswa uye kutanga. Icho chinangwa chinogona kuchengetwa mukusiyana kwezvakatipoteredza kuti usvetuke danho iri zvachose. Ona Kusarudza Chinangwa kuti uwane rumwe ruzivo.
Kana matanho apfuura akaitwa nemazvo, iyi inotevera menyu inobuda:

Ichi chishandiso chinoenderana neChikamu 15 cheFCC Mitemo. Kushanda kunoenderana nemamiriro maviri anotevera

• Ichi chishandiso chinogona kusakonzera kukanganisa kunokuvadza.
• Muchina uyu unofanirwa kugamuchira chero kukanganisa kwakagamuchirwa, kusanganisira kukanganisa kunogona kukonzera kushanda kusingade.
• Chero shanduko kana zvigadziriso zvisina kutenderwa nebato rine chekuita nekutevedzwa zvinogona kukanganisa mushandisi simba rekushandisa mudziyo.
• Mudziyo uyu unoenderana neFCC RF radiation exposure limits yakatemerwa nharaunda isingadzoreki. Ichi chishandiso uye antenna yacho haifanire kunge iri-pamwe kana kushanda pamwe chete nechero imwe antenna kana transmitter. Antennas anoshandiswa kune iyi transmitter anofanirwa kuisirwa kuti ape chinhambwe chekuparadzanisa chingangoita makumi maviri masendimita kubva kuvanhu vese uye haafanirwe kunge ari pamwe chete kana kushanda akabatana nechero imwe antenna kana transmitter.

OEM Kubatanidzwa Mirayiridzo
Ichi chishandiso chinoitirwa chete kune vanosanganisa OEM pasi pemamiriro anotevera:

• Iyo transmitter module inogona kunge isiri-inowanikwa nechero imwe transmitter kana antenna.
• Iyo module ichashandiswa chete neyekunze antenna (s) iyo yakatanga kuedzwa uye yakasimbiswa neiyi module.
• Chero bedzi mamiriro ari pamusoro asangana, imwe transmitter bvunzo haizodikanwa. Nekudaro, iyo yekubatanidza yeOEM ichiri nebasa rekuyedza yavo yekupedzisira-chigadzirwa kune chero yakawedzera kutevedza zvinodiwa zvinodiwa neiyi module yakaiswa (yeex.ample, dhijitari mudziyo kuburitsa, PC peripheral zvinodiwa, nezvimwewo).

Kutendeseka kwekushandisa iyo Module Certification
Muchiitiko chekuti aya mamiriro haagone kusangana (semuenzanisoampuye mamwe magadzirirwo elaptop kana kubatanidza nzvimbo neimwe transmitter), ipapo mvumo yeFCC yemodule iyi yakabatana nemidziyo yekutambira haichanzi ishande uye iyo FCC ID yemodule haigone kushandiswa pachigadzirwa chekupedzisira. Mumamiriro ezvinhu aya, musanganisi weOEM achaita basa rekuongororazve chigadzirwa chekupedzisira (kusanganisira chinotakurisa) uye kuwana mvumo yeFCC yakaparadzana.

End Product Labeling
Chigadzirwa chekupedzisira chinofanira kunyorwa munzvimbo inoonekwa neinotevera: "Ine Transmitter Module FCC ID: 2AC7Z-ESPC3WROOMU".
