Microprocessor: ESP32-S3FN8 (Xtensa® 32-bit LX7 dual-core processor, mashanu-stage pombi rack chimiro, frequency kusvika 240 MHz).
SX1262 LoRa node chip.
Type-C USB interface, ine matanho ekudzivirira akazara senge voltage regulator, ESD dziviriro, pfupi dunhu kudzivirira, uye RF kudzivirira. Pabhodhi SH1.25-2 bhatiri interface, yakabatanidzwa lithium bhatiri management system (charge uye discharge management, overcharge kuchengetedzwa, bhatiri kuona simba, USB / bhatiri simba otomatiki switching).
Iyo onboard 0.96-inch 128 * 64 dot matrix OLED kuratidza inogona kushandiswa kuratidza debugging ruzivo, simba rebhatiri uye rumwe ruzivo.
Yakabatanidzwa WiFi, LoRa, uye Bluetooth katatu-network yekubatanidza, paboard Wi-Fi, Bluetooth-yakananga 2.4GHz simbi chitubu antenna, uye yakachengeterwa IPEX (U.FL) interface yekushandisa LoRa.
Yakabatanidzwa CP2102 USB kune serial port chip kuitira nyore kurodha chirongwa uye kugadzirisa ruzivo kudhinda.
Iyo ine yakanaka RF yedunhu dhizaini uye yakaderera simba rekushandisa dhizaini.
Kukura Kwechigadzirwa
Mirayiridzo Yekushandisa
Iyi purojekiti yakanyatsogadzirwa kubva kuESP32 chirongwa. Nechikonzero ichi, takagadzirisa zviri mukati me "variants" folda uye "boards.txt" (yakawedzera tsananguro uye ruzivo rwebhodhi rekuvandudza), izvo zvinoita kuti zvive nyore kune vashandisi (kunyanya vanotanga) kushandisa ESP32 series mabhodhi ekuvandudza anogadzirwa nekambani yedu.
1. Hardware Kugadzirira
- ESP32: Uyu ndiye mutongi mukuru, ane basa rekubatanidza basa rezvimwe zvikamu zvese.
- SX1262: LoRa module yekureba isina waya yekutaurirana.
- OLED kuratidzwa: inoshandiswa kuratidza node mamiriro kana data.
- Wi-Fi module: Yakavakwa-mukati ESP32 kana yekuwedzera Wi-Fi module yekubatanidza kuInternet.
2. Hardware Kubatanidza
- Batanidza iyo SX1262 LoRa module kune akatsanangurwa mapini eESP32 zvinoenderana nedhetabheti.
- Iyo OLED kuratidzwa yakabatana neESP32, kazhinji ichishandisa SPI kana I2C interface.
- Kana ESP32 pachayo isina Wi-Fi basa, unofanirwa kubatanidza imwe Wi-Fi module.
3. Kugadziriswa kweSoftware • Firmware Kunyora
- Shandisa IDE inotsigira ESP32 yekuronga.
- Rongedza LoRa module paramita, senge frequency, chiratidzo bandwidth, coding rate, nezvimwe.
- Nyora kodhi kuverenga sensor data uye kuitumira kuburikidza neLoRa.
- Seta iyo OLED kuratidzwa kuratidza zvirimo, senge sensor data, LoRa chiratidzo chesimba, nezvimwe.
- Gadzirisa iyo yeWi-Fi yekubatanidza, kusanganisira SSID nepassword, uye inokwanisika kodhi yekubatanidza yegore.
4. Gadzira uye uise
- Nyora kodhi uye ita shuwa kuti hapana zvikanganiso zve syntax.
- Isa iyo kodhi kuESP32.
5. Kuedza uye kugadzirisa
- Edza kana iyo LoRa module inogona kutumira uye kugamuchira data zvakabudirira.
- Ita shuwa kuti OLED kuratidza inoratidza ruzivo nenzira kwayo.
- Tarisa kuti Wi-Fi yekubatanidza uye kuendesa data paInternet zviri kushanda nemazvo.
6. Deployment and Monitoring
- Isa node kune chaiwo maapplication mamiriro.
- Tarisa mamiriro ekumhanya uye kuendesa data kwemanodhi.
Zvekungwaririra
- Ita shuwa kuti zvikamu zvese zvinoenderana uye zvakanyatsobatanidzwa.
- Paunenge uchinyora kodhi, tarisa uye uteedzere chikamu chega chega dhetabheti uye raibhurari nhungamiro yekushandisa.
- Nekufambisa kureba, zvingave zvakakosha kugadzirisa ma parameter eLoRa module kuti uwedzere kushanda.
- Kana ikashandiswa mukati, iyo Wi-Fi yekubatanidza ingangoda imwe gadziriso kana kusimudzira. Ndokumbira ugare uchifunga kuti nhanho dziri pamusoro igwara rakazara uye iwo chaiwo ruzivo runogona kusiyana, kunyanya kana zvasvika kune chaiyo hardware uye software maraibhurari. Iva nechokwadi chekudzoreraview uye uteedzere zvese zvine chekuita nemagwaro uye mirairo yekuchengetedza. Kana iwe ukasangana nechero matambudziko panguva yekumisikidza kana kushandiswa, zvinogara zvakanaka kubvunza zviri pamutemo zvinyorwa kana kubata tekinoroji yemugadziri.
