Ibhodi le-Luatos ESP32-C3 MCU

Ulwazi Lomkhiqizo

I-ESP32-C3 iyibhodi ye-microcontroller enenkumbulo engu-16MB. Ine-interface ye-UART engu-2, i-UART0 ne-UART1, ne-UART0 esebenza njengendawo yokulanda. Ibhodi liphinde lifake i-5-channel 12-bit ADC enobuningi obungu-sampisilinganiso esingu-100KSPS. Ukwengeza, ine-interface ye-SPI enesivinini esiphansi kumodi eyinhloko kanye nesilawuli se-IIC. Kukhona izindawo ezi-4 ze-PWM ezingasebenzisa noma iyiphi i-GPIO, kanye nezikhonkwane ze-GPIO zangaphandle eziyi-15 ezingaphindwaphindwa. Ibhodi lifakwe izinkomba ezimbili ze-SMD LED, inkinobho yokusetha kabusha, inkinobho ethi BOOT, kanye nembobo yokususa iphutha ye-USB eya ku-TTL.

Imiyalo yokusetshenziswa komkhiqizo

1. Ngaphambi kokunika amandla i-ESP32, qiniseka ukuthi iphinikhodi ye-BOOT (IO09) ayidonselwa phansi ukuze ugweme ukungena kumodi yokulanda.
2. Ngesikhathi senqubo yokuklama, akunconyiwe ukudicilela phansi iphinikhodi ye-IO08 ngaphandle, njengoba kungase kuvimbele ukulanda ngembobo ye-serial uma iphinikhodi iphansi phakathi nenqubo yokulanda nokuyishisa.
3. Kumodi ye-QIO, i-IO12 (GPIO12) ne-IO13 (GPIO13) ziphindaphindeka kumasiginali we-SPI i-SPIHD ne-SPIWP.
4. Bheka kuhlelo ukuze uthole ireferensi eyengeziwe ku-pinout. Chofoza lapha ukufinyelela uhlelo.
5. Qinisekisa ukuthi noma yiziphi izinguqulo zangaphambilini zephakheji ye-ESP32 ziyakhishwa ngaphambi kokusebenzisa iphakheji yokufaka.
6. Ukufaka uhlelo kanye nephakheji ye-arduino-esp32, landela lezi zinyathelo:
   1. Vula ukulanda kwesofthiwe okusemthethweni webbese ukhetha isistimu ehambisanayo namabhithi esistimu ozowalanda.
   2. Qalisa uhlelo olulandiwe futhi ulufake usebenzisa izilungiselelo ezizenzakalelayo.
   3. Thola indawo yokugcina ye-espressif/arduino-esp32 ku-GitHub bese uchofoza kusixhumanisi sokufaka.
   4. Kopisha i URL okuthiwa isixhumanisi sokukhishwa kwentuthuko.
   5. Ku-Arduino IDE, chofoza File > Izintandokazi > Imenenja yamabhodi engeziwe URLs bese wengeza i URL ikopishwe esinyathelweni sangaphambilini.
   6. Iya kokuthi Umphathi Webhodi ku-Arduino IDE bese ufaka iphakheji ye-ESP32.
   7. Khetha Amathuluzi > Ibhodi bese ukhetha i-ESP32C3 Dev Module ohlwini.
   8. Shintsha i-flash mode ibe yi-DIO ngokuya kokuthi Amathuluzi > I-Flash Mode bese ushintsha i-USB CDC ku-Boot ukuze uvule.
7. Ukusethwa kwakho kwe-ESP32 manje sekukulungele ukusebenza! Ungayihlola ngokusebenzisa uhlelo lokubonisa ukuze uqinisekise ukuthi yonke into isebenza kahle.

PHELILEVIEW

Ibhodi lokuthuthukisa le-ESP32 lakhiwe ngokususelwe ku-chip ye-ESP32-C3 evela ku-Espressif Systems.
Inesici esincane sefomu kanye ne-stamp ukwakhiwa kwembobo, okwenza kube lula ukuthi abathuthukisi basebenzise.Ibhodi lisekela izixhumanisi zokusebenzelana eziningi, okuhlanganisa i-UART, GPIO, SPI, I2C, ADC, ne-PWM, futhi ilungele amadivaysi eselula, ama-electronics agqokekayo, kanye nezinhlelo zokusebenza ze-IoT ezinamandla aphansi ukusebenza.

Ingasebenza njengesistimu ezimele noma idivayisi yocingo ku-MCU eyinhloko, inikeza imisebenzi ye-Wi-Fi ne-Bluetooth ngokusebenzisa i-SPI/SDIO noma i-I2C/UART.

EBHODENI USIZO

• Leli bhodi lokuthuthukisa line-flash ye-SPI eyodwa enamandla okugcina angu-4MB, anganwetshwa aze afike ku-16MB.
• Ine-interface ye-UART engu-2, i-UART0 ne-UART1, ne-UART0 esebenza njengendawo yokulanda.
• Kukhona i-5-channel 12-bit ADC kuleli bhodi, enobukhulu obungu-sampisilinganiso esingu-100KSPS.
• I-interface ye-SPI enesivinini esiphansi nayo ifakiwe kumodi eyinhloko.
• Kukhona isilawuli se-IIC kuleli bhodi.
• Inokuxhumana okungu-4 kwe-PWM okungasebenzisa noma iyiphi i-GPIO.
• Kukhona izikhonkwane ze-GPIO zangaphandle eziyi-15 ezingaphindwaphindwa.
• Ukwengeza, ihlanganisa izinkomba ezimbili ze-SMD LED, inkinobho yokusetha kabusha, inkinobho ye-BOOT, kanye nembobo yokususa iphutha ye-USB eya ku-TTL.

AMANOTHI ASEBENZISA

• Ukuze ugweme i-ESP32 ukuthi ingangeni kumodi yokulanda, iphinikhodi ye-BOOT (IO09) akufanele idonswe phansi ngaphambi kokunika amandla.
• Akunconywa ukudicilela phansi iphinikhodi ye-IO08 ngaphandle uma uklama, njengoba lokhu kungase kuvimbele ukulanda ngembobo ye-serial uma iphinikhodi iphansi phakathi nenqubo yokulanda nokuyishisa.
• Kumodi ye-QIO, i-IO12 (GPIO12) ne-IO13 (GPIO13) ziphindaphindeka kumasiginali we-SPI i-SPIHD ne-SPIWP, kodwa ngokunyuka kokutholakala kwe-GPIO, ibhodi lokuthuthukisa lisebenzisa i-2-wire SPI kumodi ye-DIO, futhi ngenxa yalokho, i-IO12 ne-IO13 azixhunyiwe. ukukhanyisa. Uma usebenzisa isofthiwe ezihlanganiselwe yona, i-flash kufanele ilungiselelwe kumodi ye-DIO ngokufanele.
• Njengoba i-VDD yeflashi ye-SPI yangaphandle isivele ixhunywe ohlelweni lokuphakela amandla angu-3.3V, asikho isidingo sokucushwa okwengeziwe kokuphakelwa kwamandla, futhi ingafinyelelwa kusetshenziswa indinganiso.
  2- Imodi yokuxhumana ye-SPI yocingo.
• Ngokuzenzakalelayo, i-GPIO11 isebenza njengephinikhodi ye-VDD ye-SPI flash, futhi ngaleyo ndlela idinga ukucushwa ngaphambi kokuthi isetshenziswe njenge-GPIO.

UKULUNGISWA KWENDAWO YOKUTHUTHUKISA

Qaphela: Isistimu yokuthuthukisa elandelayo yi-Windows ngokuzenzakalelayo.

QAPHELA: Sicela uqinisekise ukuthi ukhiphe noma yiziphi izinguqulo zangaphambilini zephakheji ye-ESP32 ngaphambi kokusebenzisa le phakheji yokufaka.
Ungakwenza lokhu ngokuzulazulela kufolda ethi “%LOCALAPPDATA%/Arduino15/packages” kufolda file umphathi, futhi isusa ifolda ebizwa ngokuthi "esp32".

1. Vula ukulanda kwesofthiwe okusemthethweni webikhasi, bese ukhetha isistimu ehambisanayo namabhithi esistimu ozowalanda.
2. Ungakhetha okuthi “Vele Ulande”, noma “Nikela futhi Ulande”.
3. Gijimani ukuze ufake uhlelo futhi ulufake lonke ngokuzenzakalelayo.
4. Faka i-arduino-esp32
   • Bheka a URL okuqanjwe isixhumanisi sokukhishwa kokuthuthukiswa futhi kwakopishwa.
   • Ku-Arduino IDE, chofoza File > Izintandokazi > Imenenja yamabhodi engeziwe URLs bese wengeza i URL okutholile esinyathelweni sesi-2.
   • Manje, buyela kuMphathi Webhodi bese ufake iphakheji ye-“ESP32”.
   • Ngemva kokufaka, khetha Amathuluzi > Ibhodi bese ukhetha “ESP32C3 Dev Module” ohlwini.
   • Ekugcineni, shintsha i-flash mode ibe yi-DIO ngokuya kokuthi Amathuluzi > I-Flash Mode, futhi ushintshe i-USB CDC kokuthi I-Boot ukuze Usebenze.

Ukusethwa kwakho kwe-ESP32 manje sekukulungele ukusebenza! Ukuze uyihlole, ungaqalisa uhlelo lokubonisa ukuze uqinisekise ukuthi yonke into isebenza kahle.
