ESP32 LoRa 32 kwamitin ci gaban WIFI babban kwamitin ci gaban IoT ne. Tun lokacin da aka ƙaddamar da shi, masu haɓakawa da masana'antun ke son shi. Sabuwar nau'in V3 da aka ƙaddamar yana riƙe ayyuka kamar Wi-Fi, BLE, LoRa, nunin OLED, da sauransu. Yana da wadatattun musaya na gefe, ƙirar kewayen RF mai kyau da ƙirar ƙarancin wutar lantarki, kuma yana da nau'ikan hanyoyin tsaro na hardware na musamman. Cikakken tsarin tsaro yana ba guntu damar saduwa da tsauraran buƙatun tsaro. Shi ne mafi kyawun zaɓi don birni mai wayo, gonaki, gida, sarrafa masana'antu, tsaron gida, karatun mita mara waya da masu haɓaka IoT.

Umarnin don Amfani
An rufe wannan aikin gaba ɗaya daga aikin ESP32. A kan wannan, mun gyara abubuwan da ke cikin babban fayil na "bambance-bambancen" da "boards.txt" (ƙara ma'anar da bayanin hukumar ci gaba), wanda ya sa ya fi sauƙi ga masu amfani (musamman masu farawa) don amfani da allon ci gaba na ESP32 da kamfaninmu ya samar.
1. Shirye-shiryen Hardware
- ESP32: Wannan shine babban mai sarrafawa, alhakin daidaita aikin duk sauran abubuwan haɗin gwiwa.
- SX1262: LoRa module don sadarwa mara igiyar nesa mai nisa.
- Nunin OLED: ana amfani dashi don nuna matsayin kumburi ko bayanai.
- Tsarin Wi-Fi: ESP32 da aka gina a ciki ko ƙarin tsarin Wi-Fi don haɗawa da Intanet.
2. Hadin kayan masarufi
- Haɗa ƙirar SX1262 LoRa zuwa ƙayyadadden fil na ESP32 bisa ga takaddar bayanan.
- An haɗa nunin OLED zuwa ESP32, gabaɗaya ta amfani da SPI ko I2C dubawa.
- Idan ESP32 kanta ba ta da aikin Wi-Fi, kuna buƙatar haɗa ƙarin tsarin Wi-Fi.
3. Kanfigareshan Software • Rubutun Firmware
- Yi amfani da IDE mai goyan bayan ESP32 don shirye-shirye.
- Sanya sigogi na LoRa, kamar mitar, bandwidth na sigina, ƙimar coding, da sauransu.
- Rubuta lamba don karanta bayanan firikwensin kuma aika ta LoRa.
- Saita nunin OLED don nuna abun ciki, kamar bayanan firikwensin, ƙarfin siginar LoRa, da sauransu.
- Sanya haɗin Wi-Fi, gami da SSID da kalmar wucewa, da yiwuwar haɗin haɗin gajimare.
4. Tara da upload
- Haɗa lambar kuma tabbatar da cewa babu kurakurai.
- Loda lambar zuwa ESP32.
5. Gwaji da gyara kuskure
- Gwada ko tsarin LoRa zai iya aikawa da karɓar bayanai cikin nasara.
- Tabbatar cewa nunin OLED yana nuna bayanai daidai.
- Tabbatar cewa haɗin Wi-Fi da canja wurin bayanan Intanet suna aiki yadda ya kamata.
6. Aiwatar da Kulawa
- Sanya nodes zuwa ainihin yanayin aikace-aikacen.
- Kula da yanayin gudana da watsa bayanai na nodes.
Matakan kariya
- Tabbatar cewa duk abubuwan haɗin gwiwa sun dace kuma an haɗa su da kyau.
- Lokacin rubuta lamba, bincika kuma bi bayanan bayanan kowane bangare da jagororin amfani da ɗakin karatu.
- Don watsa nisa mai nisa, yana iya zama dole a daidaita ma'auni na ƙirar LoRa don haɓaka aiki.
- Idan ana amfani da shi a cikin gida, haɗin Wi-Fi na iya buƙatar ƙarin tsari ko haɓakawa. Da fatan za a tuna cewa matakan da ke sama jagora ne na gabaɗaya kuma ainihin cikakkun bayanai na iya bambanta, musamman idan ya zo ga takamaiman ɗakunan karatu na hardware da software. Tabbatar sakeview kuma bi duk takaddun da suka dace da jagororin aminci. Idan kun haɗu da kowace matsala yayin daidaitawa ko amfani, yana da kyau koyaushe ku tuntuɓi takaddun hukuma ko tuntuɓi goyan bayan fasaha na masana'anta.
