Luatos ESP32-C3 MCU Board

Zambiri Zamalonda

ESP32-C3 ndi bolodi ya microcontroller yokhala ndi 16MB ya kukumbukira. Ili ndi mawonekedwe a 2 UART, UART0 ndi UART1, yokhala ndi UART0 yomwe imagwira ntchito ngati doko lotsitsa. Bungweli limaphatikizanso ndi 5-channel 12-bit ADC yokhala ndi ma sampMtengo wa 100KSPS. Kuphatikiza apo, ili ndi mawonekedwe otsika kwambiri a SPI mumachitidwe apamwamba komanso chowongolera cha IIC. Pali zolumikizira 4 za PWM zomwe zitha kugwiritsa ntchito GPIO iliyonse, ndi zikhomo 15 zakunja za GPIO zomwe zitha kuchulukitsidwa. Bolodi ili ndi zizindikiro ziwiri za SMD LED, batani lokhazikitsiranso, batani la BOOT, ndi USB kupita ku TTL kutsitsa debug port.

Malangizo Ogwiritsira Ntchito Zogulitsa

1. Musanayatse ESP32, onetsetsani kuti pini ya BOOT (IO09) sinagwetsedwe pansi kuti musalowe mumayendedwe otsitsa.
2. Pakukonza, sikovomerezeka kutsitsa pini ya IO08 kunja, chifukwa zingalepheretse kutsitsa kudzera pa doko la serial pomwe pini ili yotsika pakutsitsa ndikuwotcha.
3. Mu mawonekedwe a QIO, IO12 (GPIO12) ndi IO13 (GPIO13) amachulukitsa ma sign a SPI SPIHD ndi SPIWP.
4. Onaninso schema kuti muwonjezere pa pinout. Dinani Pano kuti mupeze schema.
5. Onetsetsani kuti matembenuzidwe aliwonse am'mbuyomu a phukusi la ESP32 achotsedwa musanagwiritse ntchito phukusili.
6. Kuti muyike pulogalamuyi ndi phukusi la arduino-esp32, tsatirani izi:
   1. Tsegulani pulogalamu yotsitsa yovomerezeka webtsamba ndikusankha njira yofananira ndi ma bits otsitsa kuti mutsitse.
   2. Kuthamanga pulogalamu dawunilodi ndi kukhazikitsa ntchito kusakhulupirika zoikamo.
   3. Pezani malo a espressif/arduino-esp32 pa GitHub ndipo dinani Kuyika ulalo.
   4. Koperani URL dzina lachitukuko chotulutsa ulalo.
   5. Mu Arduino IDE, dinani File > Zokonda > Woyang'anira matabwa owonjezera URLs ndi kuwonjezera URL anakopera mu sitepe yapita.
   6. Pitani ku Boards Manager mu Arduino IDE ndikuyika phukusi la ESP32.
   7. Sankhani Zida > Board ndikusankha ESP32C3 Dev Module pamndandanda.
   8. Sinthani mawonekedwe a Flash kukhala DIO popita ku Zida> Flash Mode ndikusintha USB CDC pa Boot kuti Yambitsani.
7. Kukonzekera kwanu kwa ESP32 tsopano kwakonzeka! Mukhoza kuyesa poyendetsa pulogalamu yowonetsera kuti muwonetsetse kuti zonse zikuyenda bwino.

ZATHAVIEW

Bungwe lachitukuko la ESP32 lidapangidwa kutengera chip ESP32-C3 kuchokera ku Espressif Systems.
Ili ndi mawonekedwe ang'onoang'ono ndi Stamp kupanga dzenje, zomwe zimapangitsa kuti zikhale zosavuta kuti omanga azigwiritsa ntchito.Bolodiyi imathandizira maulendo angapo, kuphatikizapo UART, GPIO, SPI, I2C, ADC, ndi PWM, ndipo ndi yabwino kwa zipangizo zam'manja, zamagetsi zamagetsi, ndi ntchito za IoT zokhala ndi mphamvu zochepa.

Itha kugwira ntchito ngati njira yoyimirira kapena chipangizo cholumikizira ku MCU yayikulu, yopereka ntchito za Wi-Fi ndi Bluetooth kudzera pa SPI/SDIO kapena I2C/UART.

ON BOARD RESOURCE

• Gulu lachitukukoli lili ndi kung'anima kwa SPI imodzi yokhala ndi 4MB yosungirako, yomwe imatha kukulitsidwa mpaka 16MB.
• Ili ndi mawonekedwe a 2 UART, UART0 ndi UART1, yokhala ndi UART0 yomwe imagwira ntchito ngati doko lotsitsa.
• Pali 5-channel 12-bit ADC pa bolodi ili, yokhala ndi ma s opambanaampMtengo wa 100KSPS.
• Mawonekedwe otsika kwambiri a SPI amaphatikizidwanso mu master mode.
• Pali wolamulira wa IIC pa bolodi ili.
• Ili ndi mawonekedwe a 4 PWM omwe amatha kugwiritsa ntchito GPIO iliyonse.
• Pali zikhomo 15 zakunja za GPIO zomwe zitha kuchulukitsidwa.
• Kuphatikiza apo, imaphatikizapo zizindikiro ziwiri za SMD LED, batani lokhazikitsiranso, batani la BOOT, ndi doko la USB kupita ku TTL lotsitsa debug.

DIMENSIONS (DINANI KUTI MUDZIWA)

ZOTHANDIZA ZOKHUDZA

• Kuti mupewe ESP32 kuti isalowe mumalowedwe otsitsa, pini ya BOOT (IO09) siyenera kugwetsedwa isanayambike.
• Sitikulimbikitsidwa kutsitsa pini ya IO08 panja popanga, chifukwa izi zitha kulepheretsa kutsitsa kudzera pa doko la serial pomwe pini ili yotsika pakutsitsa ndikuwotcha.
• Mu mawonekedwe a QIO, IO12 (GPIO12) ndi IO13 (GPIO13) amachulukitsidwa kwa ma sign a SPI SPIHD ndi SPIWP, koma pakuwonjezeka kwa GPIO kupezeka, gulu lachitukuko limagwiritsa ntchito 2-waya SPI mu DIO mode, ndipo motero, IO12 ndi IO13 sizilumikizidwa. ku flash. Mukamagwiritsa ntchito pulogalamu yodzipangira nokha, flash iyenera kusinthidwa kukhala DIO mode moyenerera.
• Popeza VDD yakunja kwa SPI flash yalumikizidwa kale kumagetsi a 3.3V, palibe chofunikira pakusintha kwamagetsi owonjezera, ndipo imatha kupezeka pogwiritsa ntchito muyezo.
  2- waya SPI kulumikizana mode.
• Mwachikhazikitso, GPIO11 imakhala ngati pini ya VDD ya SPI flash, motero imafuna kasinthidwe isanayambe kugwiritsidwa ntchito ngati GPIO.

KUSINTHA KWA ZINTHU ZOCHITIKA

Zindikirani: Dongosolo lachitukuko lotsatirali ndi Windows mwachisawawa.

ZINDIKIRANI: Chonde onetsetsani kuti mwachotsa mitundu ina yonse yam'mbuyomu ya phukusi la ESP32 musanagwiritse ntchito phukusili.
Mutha kuchita izi popita ku chikwatu "% LOCALAPPDATA%/Arduino15/packages" mu file manejala, ndikuchotsa chikwatu chotchedwa "esp32".

1. Tsegulani pulogalamu yotsitsa yovomerezeka webtsamba, ndikusankha njira yofananira ndi ma bits adongosolo kuti mutsitse.
2. Mutha kusankha "Ingotsitsani", kapena "Perekani & Tsitsani".
3. Thamangani kukhazikitsa pulogalamuyo ndikuyiyika zonse mwachisawawa.
4. Ikani arduino-esp32
   • Fufuzani a URL adatchulidwa ulalo wotulutsa ndikukopera.
   • Mu Arduino IDE, dinani File > Zokonda > Woyang'anira matabwa owonjezera URLs ndi kuwonjezera URL zomwe mwapeza mu sitepe 2.
   • Tsopano, bwererani ku Boards Manager ndikuyika phukusi la "ESP32".
   • Pambuyo kukhazikitsa, sankhani Zida> Board ndikusankha "ESP32C3 Dev Module" pamndandanda.
   • Pomaliza, sinthani mawonekedwe a Flash kukhala DIO popita ku Zida> Flash Mode, ndikusintha USB CDC pa Boot kuti Yambitsani.

Kukhazikitsa kwanu kwa ESP32 tsopano kwakonzeka! Kuti muyese, mutha kuyendetsa pulogalamu yowonetsera kuti muwonetsetse kuti zonse zikuyenda bwino.
