Isingeniso
ESP32-JCI-R
I-ESP32-JCI-R iyimojula enamandla, ejwayelekile ye-Wi-Fi+BT+BLE MCU eqondise inhlobonhlobo yezinhlelo zokusebenza, kusukela kumanethiwekhi ezinzwa ezinamandla aphansi kuya emisebenzini edingeka kakhulu, njengombhalo wekhodi wezwi, ukusakaza umculo kanye nokuqopha i-MP3. . Umnyombo wale mojula yi-chip ye-ESP32-D0WD-V3. I-chip eshumekiwe yakhelwe ukuthi ikhule futhi ihambisane nezimo. Kukhona ama-CPU cores amabili angalawulwa ngawodwana, futhi imvamisa yewashi le-CPU iyalungiseka ukusuka ku-80 MHz ukuya ku-240 MHz. Umsebenzisi angase futhi acime i-CPU futhi asebenzise i-co-processor yamandla aphansi ukuze ahlale eqapha ama-peripherals ngezinguquko noma ukweqa ama-threshold. I-ESP32 ihlanganisa isethi ecebile yama-peripherals, kusukela kuzinzwa zokuthinta ezinamakhono, izinzwa zehholo, isixhumi esibonakalayo sekhadi le-SD, i-Ethernet, i-SPI yesivinini esikhulu, i-UART, i-I2S ne-I2C. Ukuhlanganiswa kwe-Bluetooth, i-Bluetooth LE kanye ne-Wi-Fi kuqinisekisa ukuthi izinhlelo zokusebenza eziningi zingaqondiswa nokuthi imojuli inobufakazi besikhathi esizayo: ukusebenzisa i-Wi-Fi kuvumela ububanzi obukhulu bomzimba kanye nokuxhumeka okuqondile ku-inthanethi nge-Wi-Fi. irutha ngenkathi isebenzisa i-Bluetooth ivumela umsebenzisi ukuthi axhumeke kalula kufoni noma asakaze amabhakhoni wamandla aphansi ukuze ibonwe. Isikhathi sokulala se-chip ye-ESP32 singaphansi kuka-5 μA, okuyenza ifanelekele izinhlelo zokusebenza zikagesi ezisebenza ngamandla ebhethri nezigqokekayo. I-ESP32 isekela isilinganiso sedatha esingafika ku-150 Mbps, namandla okukhipha angu-20 dBm othini ukuze kuqinisekiswe ububanzi bomzimba obubanzi kakhulu. Ngakho-ke i-chip ihlinzeka ngemininingwane ehamba phambili embonini kanye nokusebenza okungcono kakhulu kokuhlanganiswa kwe-elekthronikhi, ububanzi, ukusetshenziswa kwamandla, nokuxhumana. Isistimu yokusebenza ekhethelwe i-ESP32 imahhalaRTOS ene-LwIP; I-TLS 1.2 ene-Hardware acceleration yakhelwe ngaphakathi. Ukuthuthukiswa okuvikelekile (okubethelwe) emoyeni (i-OTA) nakho kuyasekelwa ukuze onjiniyela bakwazi ukuqhubeka nokuthuthukisa imikhiqizo yabo ngisho nangemva kokukhululwa kwayo.
I-ESP-IDF
I-Espressif IoT Development Framework (i-ESP-IDF ngamafuphi) iwuhlaka lokuthuthukisa izinhlelo zokusebenza ezisekelwe ku-Espressif ESP32. Abasebenzisi bangathuthukisa izinhlelo zokusebenza ku-Windows/Linux/MacOS ngokusekelwe ku-ESP-IDF.

Ukuze uyithole, vula i-terminal, uye kunkomba ofuna ukuyibeka i-ESP-IDF, bese uyihlanganisa usebenzisa umyalo we-git clone:
- cd ~/esp
- i-git clone - i-recursive https://github.com/espressif/esp-idf.git
I-ESP-IDF izolandwa ku-~/esp/esp-idf.
Qaphela:
Ungaphuthelwa -inketho yokuphindaphinda. Uma usuvele uhlanganise i-ESP-IDF ngaphandle kwale nketho, sebenzisa omunye umyalo ukuze uthole wonke ama-submodule:
- cd ~/esp/esp-idf
- git submodule update -init
Setha Indlela eya ku-ESP-IDF
Izinhlelo ze-toolchain zifinyelela ku-ESP-IDF zisebenzisa i-IDF_PATH eguquguqukayo yemvelo. Lokhu okuguquguqukayo kufanele kumiswe ku-PC yakho, ngaphandle kwalokho, amaphrojekthi ngeke akhe. Ukusetha kungenziwa mathupha, isikhathi ngasinye lapho i-PC iqalwa kabusha. Enye inketho ukuyisetha unaphakade ngokuchaza i-IDF_PATH kuphrofayela yomsebenzisi. Ukuze wenze njalo, landela imiyalelo kokuthi Engeza i-IDF_PATH kuphrofayela yomsebenzisi.
Qala iphrojekthi
Manje usukulungele ukulungiselela isicelo sakho se-ESP32. Ukuze siqale ngokushesha, sizosebenzisa iphrojekthi ye-hello_world yakudalaamples directory ku-IDF.
Kopisha ukuqalisa/hello_world ku-~/esp lwemibhalo:
- cd ~/esp
- cp -r $IDF_PATH/examples/get-start/hello_world .
Ungathola futhi uhla lwama-exampamaphrojekthi ngaphansi kwe-exampuhla lwemibhalo ku-ESP-IDF. Lezi example mibhalo yephrojekthi ingakopishwa ngendlela efanayo neyethulwe ngenhla, ukuze uqale awakho amaphrojekthi.
Qaphela:
Isistimu yokwakha ye-ESP-IDF ayisekeli izikhala ezindleleni eziya ku-ESP-IDF noma amaphrojekthi.
Xhuma
Cishe usufikile. Ukuze ukwazi ukuqhubeka phambili, xhuma ibhodi le-ESP32 ku-PC, hlola ngaphansi kwasiphi imbobo se-serial ibhodi elibonakalayo bese uqinisekisa ukuthi ukuxhumana kwe-serial kusebenza yini. Uma ungenaso isiqiniseko sokuthi kwenziwa kanjani, hlola imiyalelo kokuthi Sungula Uxhumano Lwe-Serial nge-ESP32. Qaphela inombolo yembobo, njengoba izodingeka esinyathelweni esilandelayo.
Lungiselela
Njengoba usewindini letheminali, hamba kumkhombandlela wohlelo lokusebenza lwe-hello_world ngokuthayipha okuthi cd ~/esp/hello_world. Bese uqala i-menuconfig yokucushwa kwephrojekthi:
- cd ~/esp/hello_world yenza i-menuconfig
Uma izinyathelo zangaphambilini zenziwe ngendlela efanele, imenyu elandelayo izoboniswa: 
Kumenyu, zulazulela ku-Serial flasher config > Imbobo ye-serial ezenzakalelayo ukuze ulungise imbobo ye-serial, lapho iphrojekthi izolayishwa khona. Qinisekisa ukukhetha ngokucindezela u-enter, gcina
ukumisa ngokukhetha , bese uphuma kuhlelo lokusebenza ngokukhetha .
