Luatos ESP32-C3 MCU Ibhodi

Ulwazi lweMveliso

I-ESP32-C3 yibhodi ye-microcontroller ene-16MB yememori. Ibonisa ujongano lwe-UART emi-2, i-UART0 kunye ne-UART1, kunye ne-UART0 esebenza njengendawo yokukhuphela. Ibhodi ikwabandakanya i-5-channel 12-bit ADC kunye nobuninzi sampizinga le-100KSPS. Ukongezelela, ine-interface ye-SPI enesantya esisezantsi kwimodi yenkosi kunye nomlawuli we-IIC. Kukho ii-interfaces ze-PWM ezi-4 ezinokusebenzisa nayiphi na i-GPIO, kunye ne-15 yangaphandle ye-GPIO izikhonkwane ezinokuthi ziphindaphindwe. Ibhodi ixhotyiswe ngezibonakaliso ezimbini ze-SMD ze-LED, iqhosha lokusetha kwakhona, iqhosha le-BOOT, kunye ne-USB kwi-TTL yokukhuphela i-port debug port.

Imiyalelo yokusetyenziswa kwemveliso

1. Phambi kokunika amandla i-ESP32, qinisekisa ukuba iqhosha le-BOOT (IO09) alitsalwanga ezantsi ukunqanda ukungena kwindlela yokukhuphela.
2. Ngexesha lenkqubo yoyilo, akukhuthazwa ukuba ukhuphe ngaphandle kwe-IO08 pin, njengoko inokuthintela ukukhuphela nge-serial port xa i-pin iphantsi ngexesha lokukhuphela kunye nokutshisa inkqubo.
3. Kwimo ye-QIO, i-IO12 (GPIO12) kunye ne-IO13 (GPIO13) i-multiplexed kwiimpawu ze-SPI ze-SPIHD kunye ne-SPIWP.
4. Jonga kwiskim ngereferensi eyongezelelweyo kwipinout. Cofa Apha ukufikelela kwisicwangciso.
5. Qinisekisa ukuba naziphi na iinguqulelo zangaphambili zephakheji ye-ESP32 azikhutshiwe phambi kokusebenzisa ipakethe yokufakela.
6. Ukufakela inkqubo kunye nephakheji ye-arduino-esp32, landela la manyathelo:
   1. Vula ukhuphelo lwesoftware esemthethweni webiphepha kwaye ukhethe inkqubo ehambelanayo kunye namasuntswana endlela yokukhuphela.
   2. Qalisa inkqubo ekhutshelweyo kwaye uyifake usebenzisa useto olungagqibekanga.
   3. Fumana indawo yokugcina ye-espressif/arduino-esp32 kwi-GitHub kwaye ucofe kwikhonkco lokuFakela.
   4. Khuphela i URL ikhonkco lophuhliso elinikwe igama.
   5. Kwi-Arduino IDE, cofa apha File > Ezikhethwayo > Umphathi weebhodi ezongezelelweyo URLs kwaye wongeze i URL ikhutshelwe kwinyathelo langaphambili.
   6. Yiya kuMphathi weeBhodi kwi-Arduino IDE kwaye ufake iphakheji ye-ESP32.
   7. Khetha Izixhobo > Ibhodi kwaye ukhethe ESP32C3 Dev Imodyuli kuluhlu.
   8. Guqula imowudi ye-flash kwi-DIO ngokuya kwiZixhobo> Imo yeFlash kwaye utshintshe i-CDC ye-USB kwi-Boot ukuze uvule.
7. Useto lwakho lwe-ESP32 ngoku lulungele ukuhamba! Ungayivavanya ngokuqhuba inkqubo yokubonisa ukuqinisekisa ukuba yonke into isebenza ngokuchanekileyo.

PHEZULUVIEW

Ibhodi yophuhliso ye-ESP32 yenzelwe ngokusekelwe kwi-chip ye-ESP32-C3 esuka kwi-Espressif Systems.
Inomlinganiselo omncinci wefom kunye ne-stamp uyilo lomngxuma, okwenza kube lula ukuba abaphuhlisi basebenzise.Ibhodi isekela i-interfaces ezininzi, kuquka i-UART, i-GPIO, i-SPI, i-I2C, i-ADC, kunye ne-PWM, kwaye ifanelekile kwizixhobo eziphathwayo, i-electronics wearable, kunye nezicelo ze-IoT kunye nokusebenza kwamandla aphantsi.

Iyakwazi ukusebenza njengenkqubo ezimeleyo okanye isixhobo se-peripheral kwi-MCU engundoqo, ukubonelela nge-Wi-Fi kunye nemisebenzi yeBluetooth ngokusebenzisa i-SPI / SDIO okanye i-I2C / UART interfaces.

NGEBHODI IZIXHOBO

• Le bhodi yophuhliso ine-flash ye-SPI ene-4MB yokugcina umthamo, enokwandiswa ukuya kwi-16MB.
• Ibonisa ujongano lwe-UART emi-2, i-UART0 kunye ne-UART1, kunye ne-UART0 esebenza njengendawo yokukhuphela.
• Kukho i-5-channel 12-bit ADC kule bhodi, kunye nobuninzi be-sampumgangatho we-100KSPS.
• I-interface ye-SPI enesantya esisezantsi nayo ibandakanyiwe kwimowudi enkulu.
• Kukho umlawuli we-IIC kule bhodi.
• Inonxibelelwano lwe-PWM ye-4 enokusebenzisa nayiphi na i-GPIO.
• Kukho izikhonkwane ze-GPIO zangaphandle ezili-15 ezinokuphinda ziphindwe.
• Ukongeza, ibandakanya izikhombisi ezimbini ze-SMD ze-LED, iqhosha lokusetha kwakhona, iqhosha le-BOOT, kunye ne-USB kwi-TTL yokukhuphela i-debug port.

AMANQAKU ASETYENZISWAYO

• Ukunqanda i-ESP32 ekungeneni kwimowudi yokukhuphela, isikhonkwane seBOOT (IO09) akufuneki sitsalwe ezantsi phambi kokunyusa amandla.
• Akukhuthazwa ukuba ukhuphe ngaphandle i-IO08 pin xa uyilwa, njengoko oku kunokuthintela ukukhuphela nge-serial port xa i-pin iphantsi ngexesha lokukhuphela kunye nokutshisa inkqubo.
• Kwimodi ye-QIO, i-IO12 (GPIO12) kunye ne-IO13 (GPIO13) i-multiplexed kwiimpawu ze-SPI ze-SPIHD kunye ne-SPIWP, kodwa ngokunyuka kokufumaneka kwe-GPIO, ibhodi yophuhliso isebenzisa i-2-wire SPI kwimodi ye-DIO, kwaye ngokunjalo, i-IO12 kunye ne-IO13 ayixhunyiwe. ukudanyaza. Xa usebenzisa isoftwe eziqulunqiweyo, iflash kufuneka imiselwe kwimo yeDIO ngokufanelekileyo.
• Ekubeni i-VDD ye-flash ye-SPI yangaphandle sele iqhagamshelwe kwinkqubo yonikezelo lwamandla e-3.3V, akukho mfuneko yolungiselelo lonikezelo lwamandla olongezelelweyo, kwaye inokufumaneka ngokusebenzisa umgangatho.
  I-2-imowudi yonxibelelwano ye-SPI yocingo.
• Ngokungagqibekanga, i-GPIO11 isebenza njengeqhosha le-VDD lombane we-SPI, kwaye ngoko ifuna uqwalaselo phambi kokuba isetyenziswe njenge-GPIO.
