Isingeniso
I-ASR6601 iyichip ye-LoRa soc.
Ingaphakathi lisetshenziswa wumongo we-Cortex M4 ngomongo wesofthiwe we-Semtech's LoRa transceiver SX1262. Imojula ingafinyelela ku-868(ye-EU)/915Mhz ukuxhumana kwebhendi yefrikhwensi. Imojula isebenzisa idivayisi ye-LoRa enephrothokholi ye-CLASS A,B,C, i-DTU namaphrothokholi ahlukahlukene ayimfihlo. Iphrothokholi yekilasi A, B,C iyiphrothokholi ye-Lorawan engajwayelekile futhi ifanele isango lethu kuphela. I-MCU engaphakathi kwemojuli inamandla, ine-48Mhz master frequency kanye ne-16kbytes Sram, 128k flash, okwenza igxathu elikhulu ekusebenzeni kusukela ku-ASR6505 yangaphambilini. Ukuze kwehliswe izindleko zehadiwe, uhlelo lwe-Open MCU lungasetshenziswa ngokuqondile ngaphakathi ngumsebenzisi ngaphandle kokunwetshwa kwe-MCU.
Ukuzwela okukhulu kokwamukela kwemojula kufika ku- – 140dBm, amandla okudlulisa aphezulu afika ku-14dBm@868MHz(ye-EU) Band / 94dBuV/m@3m@915MHz Ibhendi.
Isici esiyinhloko:

Idizayini yesithenjwa
Ipharamitha yomsebenzi.
- Sekela ukudluliswa okungenantambo
- Isilinganiso sembobo se-serial esishintshayo kanye nebhithi yokuhlola
- Ukusekelwa kokubethelwa kwedatha yokudlulisa kanye nokuqanjwa kwekhodi
- Ukusekela imvamisa nokusetha isilinganiso
- Sekela ukulondolozwa okukhethiwe kwamapharamitha wokusetha. I-MCU yokulawula imojula ayidingi ukulondolozwa, futhi isetshenziswa ngokuhlukana njengemojula yokudlulisela
- Sekela ukusetshenziswa kwamamojula okulawula we-MCU angaphandle namamojula azimele
- Izinga lembobo ye-serial, isilinganiso se-Lora, imvamisa ye-Lora, nokhiye oyimfihlo phakathi kwenhlanganisela yokudlulisela efanayo kumele kuhambisane, futhi ukungahambisani kuzoholela ekudidekeni.
- I-LED lamp (GPIO33) flash ku-2S frequency
- Donsela i-GPIO32 phansi lapho uthumela idatha, ithunyelwe futhi ithule
- Khipha okuthi “AT + START\r\n”, kuze kube yilapho ithola lo myalelo wokucushwa kweSiqondiso kanye nokudluliswa kwedatha
- Izinga lembobo ye-serial yokutholwa okuzenzakalelayo ngu-38400, awukho umsebenzi wokuqinisekisa
Ukuhlukaniswa kwesifunda kwe-FLASH
I-Flash Yangaphakathi inesamba esingu-128kbytes, ikhasi elinosayizi ongu-4k.

Ukusetshenziswa kwe-module
Ukusetshenziswa kwemojula kungalawulwa yi-MCU yangaphandle futhi njengamamojula azimele asebenzisa amabili, nenhlanganisela engahleliwe yesilinganiso sembobo kanye nesilinganiso, ukudluliswa kobude bephakethe kusekela umkhawulo wedatha ye-byte engu-1K (1023Byte).
- Ukulawula kwe-MCU kwangaphandle
I-GPIO32 ezenzakalelayo yamandla iphezulu, i-GPIO32 idonselwa phansi ngesikhathi senqubo yokudlulisa idatha, futhi i-GPIO32 iphakeme, enganqunywa lapha ukuthi imodyuli ephukile ifile, isikhathi sokuvala kufanele sibe sikhulu kune-5.26S (ithumela i-1 K amabhayithi ngesilinganiso se-baud esingu-SF9,2400). - Uma idatha yokudlulisela ingaphezu kwe-1K, idatha ye-1K ithunyelwa kuqala ukuze iqhubeke nokuthumela idatha esele lapho i-GPIO32 ibuyiselwa phezulu, ukuze ukuthunyelwa kwendingilizi kuthunyelwe.
