Ntuziaka maka ojiji
A na-emechi ọrụ a kpamkpam site na ọrụ ESP32. Na ndabere a, anyị gbanwere ọdịnaya nke folda "variants" na "boards.txt" (gbakwunyere nkọwa na ozi nke ụlọ ọrụ mmepe), nke na-eme ka ọ dịkwuo mfe maka ndị ọrụ (karịsịa ndị mbido) iji ESP32 usoro mmepe nke ụlọ ọrụ anyị mepụtara.
1. Nkwadebe ngwaike
- ESP32: Nke a bụ isi njikwa, na-ahụ maka ịhazi ọrụ nke akụrụngwa ndị ọzọ niile.
- SX1262: LoRa modul maka nkwurịta okwu ikuku dị anya.
- Ngosipụta OLED: ejiri gosipụta ọkwa ọnụ ma ọ bụ data.
- Modul Wi-Fi: ESP32 arụnyere ma ọ bụ Wi-Fi modul agbakwunyere maka ijikọ na ịntanetị.
2. Njikọ ngwaike
- Jikọọ modul SX1262 LoRa na ntụtụ akọwapụtara nke ESP32 dịka akwụkwọ data siri dị.
- A na-ejikọta ihe ngosi OLED na ESP32, na-ejikarị SPI ma ọ bụ I2C interface.
- Ọ bụrụ na ESP32 n'onwe ya enweghị ọrụ Wi-Fi, ịkwesịrị ijikọ modul Wi-Fi ọzọ.
3. Nhazi ngwanrọ • Ide firmware
- Jiri IDE na-akwado ESP32 maka mmemme.
- Hazie parampat modul LoRa, dị ka ugboro, bandwit mgbama, ọnụọgụ koodu, wdg.
- Dee koodu iji gụọ data sensọ wee ziga ya site na LoRa.
- Tọọ ihe ngosi OLED ka ọ gosipụta ọdịnaya, dị ka data sensọ, ike mgbama LoRa, wdg.
- Hazie njikọ Wi-Fi, gụnyere SSID na paswọọdụ, yana koodu njikọ igwe ojii enwere ike.
4. Chịkọta na bulite
- Chịkọta koodu ahụ wee hụ na enweghị mperi syntax.
- Bulite koodu ahụ na ESP32.
5. Nnwale na debugging
- Nwalee ma modul LoRa nwere ike izipu ma nata data nke ọma.
- Gbaa mbọ hụ na ngosipụta OLED gosipụtara ozi nke ọma.
- Nyochaa na njikọ Wi-Fi na ịnyefe data ịntanetị na-arụ ọrụ nke ọma.
6. Ntinye na nlekota oru
- Nyefee ọnụ ọnụ na ọnọdụ ngwa n'ezie.
- Nyochaa ọnọdụ ọsọ na nnyefe data nke ọnụ.
Mkpachapụ anya
- Gbaa mbọ hụ na akụrụngwa niile dakọtara yana jikọọ nke ọma.
- Mgbe ị na-ede koodu, lelee ma soro mpempe akwụkwọ data akụrụngwa nke ọ bụla yana ntuziaka ojiji ọbá akwụkwọ.
- Maka nnyefe dị anya, ọ nwere ike ịdị mkpa ịhazigharị parampat nke modul LoRa iji kwalite arụmọrụ.
- Ọ bụrụ na ejiri ya n'ime ụlọ, njikọ Wi-Fi nwere ike ịchọ nhazi ọzọ ma ọ bụ nkwalite. Biko buru n'uche na usoro ndị a dị n'elu bụ ntuziaka izugbe na nkọwa zuru oke nwere ike ịdịgasị iche, ọkachasị ma a bịa na ọba akwụkwọ ngwaike na ngwanrọ. Jide n'aka review ma soro akwụkwọ niile dị mkpa na ntuziaka nchekwa. Ọ bụrụ na ị na-ezute nsogbu ọ bụla n'oge nhazi ma ọ bụ ojiji, ọ kacha mma mgbe niile ịkpọtụrụ akwụkwọ gọọmentị ma ọ bụ kpọtụrụ nkwado teknụzụ nke onye nrụpụta.
