ESP32 LoRa V3WIFI Bluetooth Development Board
Incazelo Yomkhiqizo
Ibhodi lokuthuthukisa i-ESP32 LoRa 32 WIFI iyibhodi yokuthuthukisa ye-IoT yakudala. Kusukela yethulwa, ibithandwa ngabathuthukisi nabakhiqizi. Inguqulo esanda kwethulwa ye-V3 igcina imisebenzi efana ne-Wi-Fi, i-BLE, i-LoRa, isibonisi se-OLED, njll. Inoxhumano olunothile lwama-peripheral, idizayini enhle ye-RF yesekethe kanye nedizayini yokusetshenziswa kwamandla okuphansi, futhi inezindlela ezihlukahlukene zokuphepha zehadiwe. Indlela yokuvikela ephelele yenza i-chip ihlangabezane nezidingo eziqinile zokuphepha. Kuyisinqumo esingcono kakhulu sedolobha elihlakaniphile, ipulazi, ikhaya, ukulawulwa kwezimboni, ukuphepha kwendlu, ukufundwa kwamamitha angenantambo kanye nabathuthukisi be-IoT.

I-Microprocessor: ESP32-S3FN8 (Xtensa® 32-bit LX7 dual-core processor, five-stage ipayipi yokubeka isakhiwo, imvamisa kufika ku-240 MHz).
I-SX1262 LoRa node chip.
Isixhumi esibonakalayo se-USB ye-Type-C, enezinyathelo zokuvikela eziphelele ezifana ne-voltagisilawuli se-e, ukuvikelwa kwe-ESD, ukuvikelwa kwesekethe emfushane, nokuvikela i-RF. Isixhumi esibonakalayo sebhethri le-SH1.25-2 elisebhodini, isistimu yokuphatha ibhethri ye-lithium ehlanganisiwe (ukuphathwa kokushaja nokukhipha, ukuvikela ukushajwa ngokweqile, ukutholwa kwamandla ebhethri, ukushintsha okuzenzakalelayo kwamandla e-USB/ibhethri).
Isibonisi se-OLED samachashazi angu-0.96-intshi angu-128*64 singasetshenziselwa ukubonisa ulwazi lokususa iphutha, amandla ebhethri nolunye ulwazi.
I-WiFi ehlanganisiwe, i-LoRa, noxhumo lwe-Bluetooth lwe-triple-network, i-Wi-Fi engaphakathi, i-Bluetooth-specific 2.4GHz metal spring antenna, nesixhumi esibonakalayo se-IPEX (U.FL) esibekelwe ukusetshenziswa kwe-LoRa.
I-CP2102 USB edidiyelwe ku-serial port chip ukuze kube lula ukulanda uhlelo nokulungisa iphutha lokuphrinta imininingwane.
Inomklamo omuhle wesekethe ye-RF kanye nomklamo wokusebenzisa amandla aphansi.
Usayizi Womkhiqizo
Imiyalo Yokusetshenziswa
Le phrojekthi yenziwe ngokuphelele kuphrojekthi ye-ESP32. Ngalesi sisekelo, silungise okuqukethwe kwefolda "ehlukile" kanye ne-"boards.txt" (kwengeza incazelo nolwazi lwebhodi lokuthuthukisa), okwenza kube lula kubasebenzisi (ikakhulukazi abaqalayo) ukusebenzisa amabhodi okuthuthukisa uchungechunge lwe-ESP32 akhiqizwa inkampani yethu.
1. Ukulungiselela Hardware
- I-ESP32: Lesi isilawuli esikhulu, esinomthwalo wemfanelo wokuxhumanisa umsebenzi wazo zonke ezinye izingxenye.
- I-SX1262: Imojula ye-LoRa yokuxhumana okungenazintambo okude.
- Isibonisi se-OLED: sisetshenziselwa ukubonisa isimo se-node noma idatha.
- Imojula ye-Wi-Fi: I-ESP32 eyakhelwe ngaphakathi noma imojuli ye-Wi-Fi eyengeziwe yokuxhuma ku-inthanethi.
2. Ukuxhumeka kwehadiwe
- Xhuma imojuli ye-SX1262 LoRa kumaphini ashiwo we-ESP32 ngokwemininingwane yedatha.
- Isibonisi se-OLED sixhunywe ku-ESP32, ngokuvamile sisebenzisa i-SPI noma i-I2C interface.
- Uma i-ESP32 ngokwayo ingenawo umsebenzi we-Wi-Fi, udinga ukuxhuma imojuli ye-Wi-Fi eyengeziwe.
3. Ukucushwa Kwesofthiwe • Ukubhala I-Firmware
- Sebenzisa i-IDE esekela i-ESP32 yokuhlela.
- Lungiselela amapharamitha wemojula ye-LoRa, njengefrikhwensi, umkhawulokudonsa wesiginali, izinga lokubhala ikhodi, njll.
- Bhala ikhodi ukuze ufunde idatha yenzwa futhi uyithumele nge-LoRa.
- Setha isibonisi se-OLED ukuze sibonise okuqukethwe, njengedatha yenzwa, amandla esignali ye-LoRa, njll.
- Lungiselela uxhumano lwe-Wi-Fi, okuhlanganisa i-SSID nephasiwedi, kanye nekhodi yokuxhumana yamafu engaba khona.
4. Hlanganisa futhi ulayishe
- Hlanganisa ikhodi futhi uqiniseke ukuthi awekho amaphutha e-syntax.
- Layisha ikhodi ku-ESP32.
5. Ukuhlola nokulungisa iphutha
- Hlola ukuthi imojuli ye-LoRa ingakwazi yini ukuthumela nokwamukela idatha ngempumelelo.
- Qiniseka ukuthi isibonisi se-OLED sibonisa ulwazi ngendlela efanele.
- Qinisekisa ukuthi uxhumano lwe-Wi-Fi nokudluliswa kwedatha ye-inthanethi kusebenza kahle.
6. Ukuthunyelwa kanye Nokuqapha
- Hambisa ama-node kuzimo zohlelo lokusebenza zangempela.
- Gada isimo esisebenzayo kanye nokudluliswa kwedatha kwamanodi.
Izinyathelo zokuzivikela
- Qiniseka ukuthi zonke izingxenye ziyahambelana futhi zixhumeke kahle.
- Lapho ubhala ikhodi, hlola futhi ulandele imininingwane yengxenye ngayinye nemihlahlandlela yokusebenzisa umtapo wolwazi.
- Ngokudluliswa kwebanga elide, kungase kudingeke ukuthi ulungise imingcele yemojuli ye-LoRa ukuze uthuthukise ukusebenza.
- Uma kusetshenziswa endlini, uxhumano lwe-Wi-Fi lungase ludinge ukulungiselelwa okwengeziwe noma ukuthuthukiswa. Sicela ukhumbule ukuthi lezi zinyathelo ezingenhla ziyigayidi evamile futhi imininingwane eqondile ingahluka, ikakhulukazi uma kuziwa kumalabhulali wehadiwe nesofthiwe. Qiniseka ukuthi uphindeview futhi ulandele zonke iziqondiso ezifanele zemibhalo nezokuphepha. Uma uhlangabezana nanoma yiziphi izinkinga ngesikhathi sokumisa noma ukusetshenziswa, kuhle ngaso sonke isikhathi ukuthi uthintane nemibhalo esemthethweni noma uxhumane nosekelo lobuchwepheshe lomkhiqizi.
