Lub onboard 0.96-nti 128 * 64 dot matrix OLED zaub tuaj yeem siv los tso saib cov ntaub ntawv debugging, roj teeb lub zog thiab lwm yam ntaub ntawv.
Integrated WiFi, LoRa, thiab Bluetooth triple-network sib txuas, onboard Wi-Fi, Bluetooth tshwj xeeb 2.4GHz hlau caij nplooj ntoos hlav kav hlau txais xov, thiab tshwj tseg IPEX (U.FL) interface rau LoRa siv.
Integrated CP2102 USB rau serial chaw nres nkoj nti rau kev yooj yim rub tawm thiab debugging cov ntaub ntawv luam tawm.
Nws muaj qhov zoo RF Circuit Court tsim thiab siv hluav taws xob tsawg tsim.
Khoom Loj
Cov lus qhia rau kev siv
Qhov project no yog cloned kiag li los ntawm ESP32 qhov project. Raws li qhov no, peb tau hloov kho cov ntsiab lus ntawm "variants" nplaub tshev thiab "boards.txt" (ntxiv cov ntsiab lus thiab cov ntaub ntawv ntawm pawg thawj coj loj hlob), uas ua rau nws yooj yim dua rau cov neeg siv (tshwj xeeb yog cov pib tshiab) siv ESP32 series txhim kho pawg thawj coj ua los ntawm peb lub tuam txhab.
1. Kev npaj kho vajtse
- ESP32: Qhov no yog tus tswj hwm lub luag haujlwm, lub luag haujlwm rau kev sib koom ua haujlwm ntawm tag nrho lwm cov khoom.
- SX1262: LoRa module rau kev sib txuas lus nyob deb deb.
- OLED zaub: siv los tso saib cov xwm txheej lossis cov ntaub ntawv.
- Wi-Fi module: Ua-nyob rau hauv ESP32 lossis ntxiv Wi-Fi module rau txuas rau Is Taws Nem.
2. Cov Khoom Txuas Ua Haujlwm
- Txuas SX1262 LoRa module rau cov pins teev ntawm ESP32 raws li cov ntaub ntawv.
- OLED zaub txuas nrog ESP32, feem ntau siv SPI lossis I2C interface.
- Yog tias ESP32 nws tus kheej tsis muaj Wi-Fi muaj nuj nqi, koj yuav tsum txuas ntxiv Wi-Fi module ntxiv.
3. Software Configuration • Firmware Sau
- Siv IDE uas txhawb ESP32 rau kev ua haujlwm.
- Configure LoRa module tsis, xws li zaus, teeb liab bandwidth, coding tus nqi, thiab lwm yam.
- Sau cov lej nyeem cov ntaub ntawv sensor thiab xa nws ntawm LoRa.
- Teem lub OLED zaub los tso saib cov ntsiab lus, xws li cov ntaub ntawv sensor, LoRa teeb liab lub zog, thiab lwm yam.
- Configure Wi-Fi kev twb kev txuas, suav nrog SSID thiab lo lus zais, thiab ua tau huab kev sib txuas code.
4. Sau thiab upload
- Sau cov cai thiab xyuas kom meej tias tsis muaj syntax yuam kev.
- Upload code rau ESP32.
5. Kev sim thiab kev debugging
- Ntsuam xyuas seb LoRa module puas tuaj yeem xa thiab txais cov ntaub ntawv tiav.
- Nco ntsoov tias OLED zaub qhia cov ntaub ntawv raug.
- Xyuas kom tseeb tias kev sib txuas ntawm Wi-Fi thiab kev hloov ntaub ntawv hauv Is Taws Nem ua haujlwm zoo.
6. Kev xa tawm thiab saib xyuas
- Deploy nodes rau tiag tiag app scenarios.
- Saib xyuas cov xwm txheej khiav thiab cov ntaub ntawv xa mus ntawm nodes.
Cov kev ceev faj
- Xyuas kom tseeb tias tag nrho cov khoom sib xyaw ua ke thiab txuas tau zoo.
- Thaum sau cov cai, xyuas thiab ua raws li txhua daim ntawv teev cov ntaub ntawv thiab cov lus qhia siv lub tsev qiv ntawv.
- Rau kev sib kis mus ntev, nws yuav tsim nyog los kho qhov tsis zoo ntawm LoRa module txhawm rau txhim kho kev ua tau zoo.
- Yog tias siv sab hauv tsev, kev sib txuas Wi-Fi yuav xav tau kev teeb tsa ntxiv lossis kev txhim kho. Thov nco ntsoov tias cov kauj ruam saum toj no yog cov lus qhia dav dav thiab cov ntsiab lus tseeb yuav txawv, tshwj xeeb tshaj yog thaum nws los txog rau cov tsev qiv ntawv kho vajtse thiab software tshwj xeeb. Nco ntsoov rovview thiab ua raws li tag nrho cov ntaub ntawv ntsig txog thiab cov lus qhia txog kev nyab xeeb. Yog tias koj ntsib teeb meem thaum lub sijhawm teeb tsa lossis siv, nws yog qhov zoo tshaj plaws los sab laj cov ntaub ntawv raug cai lossis hu rau cov chaw tsim khoom kev txhawb nqa.
