CP2102 USB e kopantsoeng ho serial port chip bakeng sa ho khoasolla habonolo le ho lokisa litaba tsa khatiso.
E na le moralo o motle oa potoloho ea RF le moralo o tlase oa tšebeliso ea matla.
Boholo ba Sehlahisoa
Litaelo tsa ho Sebelisa
Morero ona o entsoe ka botlalo ho tsoa morerong oa ESP32. Motheong ona, re fetotse litaba tsa "mefuta e fapaneng" foldareng le "boards.txt" (e kenyellelitse tlhaloso le tlhahisoleseding ea boto ea nts'etsopele), e leng se nolofalletsang basebelisi (haholo-holo ba qalang) ho sebelisa liboto tsa nts'etsopele ea lihlopha tsa ESP32 tse hlahisoang ke k'hamphani ea rona.
1. Tokiso ea Hardware
- ESP32: Enoa ke molaoli ea ka sehloohong, ea ikarabellang bakeng sa ho hokahanya mosebetsi oa likarolo tse ling kaofela.
- SX1262: Mojule oa LoRa bakeng sa puisano e telele e se nang mohala.
- Pontšo ea OLED: e sebelisetsoa ho bonts'a boemo ba node kapa data.
- Mojule oa Wi-Fi: ESP32 e hahelletsoeng kapa mojule oa tlatsetso oa Wi-Fi bakeng sa ho hokela Marang-rang.
2. Khokahano ea Hardware
- Hokela mojule oa SX1262 LoRa ho lithakhisa tse boletsoeng tsa ESP32 ho latela database.
- Pontšo ea OLED e hokahane le ESP32, hangata e sebelisa sebopeho sa SPI kapa I2C.
- Haeba ESP32 ka boeona e se na ts'ebetso ea Wi-Fi, o hloka ho hokela mojule oa tlatsetso oa Wi-Fi.
3. Sebopeho sa Software • Ho Ngola Firmware
- Sebelisa IDE e tšehetsang ESP32 bakeng sa lenaneo.
- Hlophisa liparamente tsa mojule oa LoRa, joalo ka khafetsa, bandwidth ea matšoao, sekhahla sa likhoutu, joalo-joalo.
- Ngola khoutu ho bala lintlha tsa sensor le ho li romella ka LoRa.
- Beha ponts'o ea OLED ho hlahisa litaba, joalo ka data ea sensor, matla a lets'oao la LoRa, jj.
- Lokisa khokahano ea Wi-Fi, ho kenyeletsoa SSID le password, le khoutu ea khokahano ea maru e ka bang teng.
4. Kopanya le ho kenya
- Kopanya khoutu 'me u netefatse hore ha ho na liphoso tsa syntax.
- Kenya khoutu ho ESP32.
5. Ho etsa liteko le ho lokisa liphoso
- Lekola hore na mojule oa LoRa o ka romela le ho amohela data ka katleho.
- Etsa bonnete ba hore ponts'o ea OLED e bonts'a tlhahisoleseling ka nepo.
- Netefatsa hore khokahanyo ea Wi-Fi le phetiso ea data ea Marang-rang li sebetsa hantle.
6. Phaliso le Tlhokomelo
- Kenya li-node maemong a sebele a ts'ebeliso.
- Lekola boemo ba ho sebetsa le phetiso ea data ea li-node.
Mehato ya tlhokomelo
- Etsa bonnete ba hore likarolo tsohle lia lumellana 'me li hokahane hantle.
- Ha u ngola khoutu, hlahloba 'me u latele database ea karolo ka 'ngoe le litataiso tsa tšebeliso ea laebrari.
- Bakeng sa phetisetso ea sebaka se selelele, ho ka 'na ha hlokahala hore u lokise litekanyo tsa module ea LoRa ho ntlafatsa tshebetso.
- Haeba e sebelisoa ka tlung, khokahanyo ea Wi-Fi e ka hloka tlhophiso e eketsehileng kapa ntlafatso. Ka kopo hopola hore mehato e ka holimo ke tataiso e akaretsang 'me lintlha tse tobileng li ka fapana, haholo-holo ha ho tluoa tabeng ea lilaebrari tse itseng tsa hardware le software. Etsa bonnete ba ho review le ho latela litokomane tsohle tse amehang le litataiso tsa polokeho. Haeba u kopana le mathata leha e le afe nakong ea ts'ebetso kapa tšebeliso, kamehla ho molemo ho sheba litokomane tsa molao kapa ho ikopanya le tšehetso ea theknoloji ea moetsi.
