Misela iNdawo yoPhuhliso
Isakhelo soPhuhliso lwe-Espressif IoT (i-ESP-IDF emfutshane) sisikhokelo sokuphuhlisa izicelo ezisekelwe kwii-chips ze-Espressif. Abasebenzisi banokuphuhlisa usetyenziso ngeetshiphusi ze-ESP kwiWindows/Linux/macOS esekwe kwi-ESP-IDF. Apha sithatha inkqubo yokusebenza yeLinux njenge example.
Faka i imfuneko
Ukuqokelela nge-ESP-IDF kufuneka ufumane ezi phakheji zilandelayo:
- I-CentOS 7 & 8:
sudo yum -y uhlaziyo && sudo yum faka igit wget flex inyathi gperf python3 python3-pip python3-setu - Ubuntu kunye neDebian:
sudo apt-fumana ukufaka igit wget flex bison gperf python3 python3-pip python3-setuptools cmake ninja- - IArch:
sudo pacman -S -ifuneka i-gcc git yenza i-flex bison gperf python-pip cmake ninja ccache dfu-util libuNote: - Esi sikhokelo sisebenzisa uvimba weefayili ~/esp kwi Linux njengoluhlu lofakelo lwe ESP-IDF.
- Gcina ukhumbula ukuba i-ESP-IDF ayizixhasi izithuba kwiindlela.
Fumana i-ESPIDF
Ukwakha izicelo zemodyuli ye-ESP8685-WROOM-04, udinga iilayibrari zesoftware ezibonelelwa nguEspressif Uvimba we-ESP-IDF.
Ukufumana i-ESP-IDF, yenza isilawuli sofakelo (~/esp) ukukhuphela i-ESP-IDF ukuya kunye nokudibanisa indawo yokugcina nge 'git clone': mkdir -p ~/esp cd ~/esp git clone –recursive https://github.com/espressif/esp-idf.git
I-ESP-IDF iza kukhutshelwa kwi ~/esp/esp-idf. Qhagamshelana neeNguqulelo ze-ESP-IDF ngolwazi malunga nenguqulelo ye-ESP-IDF enokusetyenziswa kwimeko ethile.
Misela izixhobo
Ngaphandle kwe-ESP-IDF, kufuneka ufake kwakhona izixhobo ezisetyenziswa yi-ESP-IDF, ezifana nomqokeleli, i-debugger, iipakethe zePython, njl njl. ekuhambeni kunye.
cd ~/esp/esp-idf./install.sh
Cwangcisa iiGuquguquko zeNdalo
Izixhobo ezifakiweyo azikafakwa kutshintsho lwemo engqongileyo PATH. Ukwenza izixhobo zisebenziseke kumgca womyalelo, ezinye iinguqu zemekobume kufuneka zisetwe. I-ESP-IDF ibonelela ngesinye iskripthi 'export.sh' esenza oko. Kwi-terminal apho uza kusebenzisa i-ESP-IDF, sebenzisa: $HOME/esp/esp-idf/export.sh Ngoku yonke into ilungile, unokwakha iprojekthi yakho yokuqala kwimodyuli ye-ESP8685-WROOM-04.
Yenza iProjekthi yakho yokuqala
Qala iProjekthi
Ngoku ukulungele ukulungiselela isicelo sakho semodyuli ye-ESP8685-WROOM-04. Ungaqala ngeprojekthi yokuqalisa/hello_world ukusuka kumxampLes directory kwi ESP-IDF.
Khuphela uqalise/hello_world ukuya ~/esp ulawulo: cd ~/esp cp -r $IDF_PATH/exampnceda/qalisa/hello_world. Kukho uluhlu lwe-example iiprojekthi kwi exampLes directory kwi ESP-IDF. Unako ukukopa nayiphi na iprojekthi ngendlela efanayo njengoko iboniswe ngasentla kwaye uyiqhube. Kwakhona kunokwenzeka ukwakha exampLes in-place, ngaphandle kokuzikopa kuqala.
Qhagamshela isixhobo sakho
Ngoku qhagamshela imodyuli yakho ye-ESP8685-WROOM-04 kwikhompyutheni kwaye ukhangele phantsi kweyiphi i-serial port imodyuli ebonakalayo. Uthotho lwezibuko kwi Linux luqala nge '/dev/tty' kumagama abo. Sebenzisa lo myalelo ungezantsi izihlandlo ezibini, kuqala ngebhodi ekhutshiweyo, emva koko iplagwe. Izibuko elivela okwesibini lelona ulidingayo: ls /dev/tty*
Phawula:
Gcina igama lezibuko likufutshane njengoko uza kulidinga kumanyathelo alandelayo.
Qwalasela
Yiya kulawulo lwakho 'hello_world' ukusuka kwiNyathelo
Qala iProjekthi, seta i-ESP8685 njengento ekujoliswe kuyo kwaye uqhube umsebenzi woqwalaselo lweprojekthi 'menuconfig'. cd ~/esp/hello_world idf.py set-target esp8685 idf.py menuconfig
Ukuseta ekujoliswe kuko nge 'idf.py set-target esp8685' kufuneka kwenziwe kube kanye, emva kokuvula iprojekthi entsha. Ukuba iprojekthi iqulethe ulwakhiwo olukhoyo kunye noqwalaselo, ziya kucocwa kwaye ziqaliswe. Ithagethi inokugcinwa kwimeko eguquguqukayo ukutsiba eli nyathelo kwaphela. Jonga Ukukhetha Ekujoliswe kuko ngolwazi olongezelelweyo.
Ukuba amanyathelo angaphambili enziwe ngokuchanekileyo, le menyu ilandelayo ivela:
Imibala yemenyu inokwahluka kwitheminali yakho. Ungayitshintsha inkangeleko ngokhetho '–isimbo'. Nceda sebenzisa 'idf.py menuconfig -help'ukufumana ulwazi oluthe vetshe.
Yakha iProjekthi
Yakha iprojekthi ngokuqhuba:
idf.py yakha
Lo myalelo uzakuqulunqa usetyenziso kunye nawo onke amalungu e-ESP-IDF, emva koko iyakuvelisa isilayidi sokuqala, itafile yolwahlulo, kunye nesicelo sokubini.
Ukuba akukho ziphoso, ukwakhiwa kuya kugqiba ngokuvelisa i-firmware binary .bin file.
Flash kwisixhobo
Dlulisa iibhinari osandula ukuzakhela kwimodyuli yakho ye-ESP8685-WROOM-04 ngokuqhuba:
idf.py -p PORT [-b BAUD] flash
Buyisela i-PORT ngegama lothotho lwemodyuli yakho ukusuka kwiNyathelo: Qhagamshela isiXhobo sakho. Unokutshintsha kwakhona ireyithi ye-flasher baud ngokufaka endaweni ye-BAUD ngesantya se-baud oyifunayo. Izinga le-baud elimiselweyo yi-460800. Ngolwazi oluthe vetshe kwiimpikiswano ze-idf.py, bona idf.py.
Phawula:
Inketho ethi 'flash' yakha ngokuzenzekelayo kwaye idanyaze iprojekthi, ngoko ke ukuqhuba 'idf.py build' akuyomfuneko
Ukuba yonke into ihamba kakuhle, isicelo esithi "hello_world" siqala ukusebenza emva kokuba ususe i-jumper kwi-IO0 kunye ne-GND,
kwaye uphinde unike amandla ibhodi yokuvavanya.
Ukubeka iliso
Ukujonga ukuba "hello_world" iyasebenza ngokwenene, chwetheza 'idf.py -p PORT monitor' (Ungalibali ukutshintsha iPORT ngeyakho
igama lezibuko lothotho).
Lo myalelo uzisa i-IDF Monitor isicelo:
Emva kokuqalisa kunye noxilongo lwelogi skrola phezulu, kuya kufuneka ubone "Molo hlabathi!" ishicilelwe sisicelo.
Ukuphuma esweni i-IDF sebenzisa indlela emfutshane Ctrl+].
Yiyo yonke into oyifunayo ukuze uqalise ngemodyuli ye-ESP8685-WROOM-04! Ngoku ukulungele ukuzama enye
exampLes kwi ESP-IDF, okanye uye ngasekunene ekuphuhliseni ezakho izicelo.

Isilumkiso:
Naluphi na utshintsho okanye uhlengahlengiso olungavunywanga ngokucacileyo liqela elinoxanduva lokuthotyelwa lunokuphelisa igunya lomsebenzisi lokusebenzisa isixhobo.
Esi sixhobo sithobela imiqathango yeFCC RF yokuvezwa kwemitha emiselwe indawo engalawulekiyo. Esi sixhobo kunye ne-eriyali akufuneki zibekwe kwindawo enye okanye zisebenze kunye nayo nayiphi na enye i-eriyali okanye isidluliseli. Ii-eriyali ezisetyenzisiweyo kwesi sidluliseli kufuneka zifakwe ukunika umgama wokwahlula ubuncinci be-20 cm ukusuka kubo bonke abantu kwaye akufuneki zibekwe kunye okanye zisebenze kunye nayo nayiphi na enye i-eriyali okanye isidluliseli.
Imiyalelo yokuHlanganisa ye-OEM
Esi sixhobo senzelwe kuphela abahlanganisi beOEM phantsi kwezi meko zilandelayo Imodyuli ingasetyenziselwa ukufakela kwenye umamkeli. I-eriyali kufuneka ifakwe ngendlela yokuba i-20 cm igcinwe phakathi kwe-eriyali kunye nabasebenzisi, kwaye imodyuli yokuhambisa imodyuli ayinakho ukudityaniswa nayo nayiphi na enye into yokuhambisa okanye i-eriyali. Imodyuli iya kusetyenziswa kuphela ngee-eriyali ezidityanisiweyo ezivavanywe kuqala zaza zaqinisekiswa ngale modyuli. Logama nje iimeko ezi-3 ezingentla zifezekisiwe, uvavanyo olongezelelweyo lothumelo aluyi kufunwa. Nangona kunjalo, umdibanisi we-OEM usenoxanduva lokuvavanya imveliso yabo yokugqibela kuyo nayiphi na imfuneko yokuthobela eyongezelelweyo nale modyuli efakiweyo (for ex.ample, ukukhutshwa kwesixhobo sedijithali, iimfuno zePC peripheral, njl.
Isaziso:
Kwimeko apho le miqathango ayinakufezekiswa (umzekeloampuqwalaselo oluthile lwelaptop okanye indawo edibeneyo kunye nenye isidluliseli), emva koko isigunyaziso seFCC sale modyuli ngokudityaniswa nesixhobo sokusingatha asisathathwa njengesemthethweni kwaye iID yeFCC yemodyuli ayinakusetyenziswa kwimveliso yokugqibela. Kwezi kunye neemeko, umdibanisi we-OEM uya kuba noxanduva lokuphonononga kwakhona. Imveliso yokugqibela (kubandakanywa umthumeli) kunye nokufumana isigunyaziso seFCC esahlukileyo.
Imveliso yokugqibela kufuneka ibhalwe kwindawo ebonakalayo ngoku kulandelayo: “Iqulethe i-ID yeModyuli yeFCC: 2AC7ZESP868504
