Imojula ye-RF MUART0-B Imojuli Yokudluliswa kwe-UART engenantambo
I-MUART0-B Wireless UART Transmission Module iyimojula esebenziseka kalula ethuthukisa ngokushesha nangokungenabuhlungu i-UART enezintambo ekudluliselweni kwe-UART okungenantambo, ngaphezu kokuba isethi yamaphini angu-1/0 akuvumela ukuthi uqede isidingo sokufaka amakhodi okwengeziwe kanye i-hardware futhi ibe nama-switch ayi-10 angalawulwa ukude omunye nomunye ukuze asetshenziswe.
Ukubukeka kwemojuli nobukhulu
Imojula ye-MUARTO-B-1-N iqukethe ucezu olulodwa lwe-Root Terminal (inombolo BO) kanye namadivayisi afinyelela kwamane (inombolo B 1 - B4). zombili ezibukeka zifana, Nokho, Umsuka noma Idivayisi ingabonakala ngelebula engemuva (esithombeni ngezansi).
Izici zemojuli
- I-vol esebenzayotage: 3.3-5.5V
- Imvamisa ye-RF: 2400MHz-2480MHz
- Ukusetshenziswa kwamandla: Idlulisa cishe u-24 mA@ +5dBm futhi ithola cishe u-23mA.
- Amandla okudlulisa: +5dBm
- Izinga lokudlulisela: I-250Kbps
- Ibanga lokudlulisela: endaweni eyi-80 kuya ku-100m endaweni evulekile
- Izinga le-Baud: 9,600bps
- Isekela ukudluliswa kwe-1-to-1 noma 1-to-multiple (kufika kokune).
Phina incazelo
Kwesobunxele kuya kwesokudla, phezulu kuya phansi
- GND Ground
- +5V5V ivolumutage input
- I-TX> ihambisana ne-RX yebhodi lokuthuthukisa i-UART
- I-RX> ihambisana ne-TX yebhodi lokuthuthukisa i-UART
- I-CEB I-PIN ye-CEB kufanele ixhunywe phansi (i-GNDI bese imojuli izosebenza manje. Le nin ingasetshenziswa njengesilawuli semodi yokonga amandla.
- PHUMA Iphinikhodi yokukhipha ye-l0 Port
- IN Iphinikhodi yokufaka ye-10 Port
- ID1, ID09ikhetha ukuthi iyiphi idivayisi ozoxhuma kuyo ngenhlanganisela OKUPHEZULU/PHANSI kwalawa maphini amabili.
Isetshenziswa kanjani
Zonke izinhlobo zamabhodi okuthuthukisa kanye nama-MC Us asekela isixhumi esibonakalayo sokuxhumana se-UART angasebenzisa le moduli ngokuqondile, futhi asikho isidingo sokufaka abashayeli abengeziwe noma izinhlelo ze-API.
Khetha inombolo yedivayisi ofuna ukuxhuma kuyo
I-TTL enezintambo evamile isakazwa ngendlela engu-1 ukuya ku-1, futhi i-MUART0-B yokudlulisa i-UART engenantambo Imojula isekela futhi imodi yoku-1 ukuya kwabaningi, kanye netheminali ye-Root ezenzakalelayo (PO] ivulwe ngeDivaysi(B1) uxhumano, uma unenye Idivayisi enenombolo 1B2-B4], Izinhlanganisela ezihlukile OKUPHEZULU/KUPHANSI zingathunyelwa ohlangothini lwe-Root lwe-ID0, iphinikhodi ye-ID1 ukuze ukhethe inombolo yedivayisi ofuna ukuxhuma kuyo, i-ID0 yohlangothi lwempande Sicela ubhekisele ku ithebula elingezansi lezinhlanganisela zokukhetha izinombolo ze-ID1.
I-ID0, iphinikhodi ye-ID1 ishintsha ngokuzenzakalelayo ithi HIGH, noma LOW uma i-GND yamukelwe
Ungabhekisela kuthebula elihambisanayo elingenhla ukuze uxhume mathupha ulayini we-GND ku-ID0 noma i-ID1 futhi uvumele itheminali ye-Root ilungiswe futhi Amadivayisi acacisiwe nawo angaxhunywa kuhlelo ngephinikhodi yebhodi yokuthuthukisa ukuze uthumele Izignali EZINGAPHANSI/PHEZULU ku-dynamically. cacisa Idivayisi ozoxhuma kuyo. Okwesiboneloampfuthi, esithombeni esingezansi, i-Arduino Nano ikhetha Idivayisi ukuze ixhumeke ngezikhonkwane ze-D4 ne-D5.
Dlulisa umlayezo
Uma usunqume ukuthi iyiphi into yedivayisi ongaxhuma kuyo, ungaqala ukudlulisa imilayezo. Okulandelayo izindlela ezintathu zokudokha ngqo i-Android kanye ne-Raspberry Pi njengesiboneloampkancane:
Ukusebenza ne-Arduino
Ngaphezu kokusebenzisa izimbobo zehadiwe ze-Arduino ze-TX/RX ngokuqondile, le mojula futhi isekela uchungechunge lwesofthiwe, ngakho-ke ingasebenzisa isofthiwe elingisa i-UART ukuze igweme ukuthatha isixhumi esibonakalayo se-UART. Okwesiboneloample, i example ngezansi ukwenza i-Arduino Nano's 2, kanye nezikhonkwane ezi-3 ukulingisa i-serial port yesofthiwe njengoba i-UART RX ne-TX idlulisela futhi yamukele imilayezo komunye nomunye, nezinye izinhlobo zamabhodi e-Arduino nazo zixhunywe ngendlela efanayo Uma ufuna ukuxhuma. idivayisi ecacisiwe ngohlelo, ungasebenzisa imiyalelo ye-Arduino ethi digitalWrite ukuze ukhiphe LOW noma HIGH to IDO, ID1 ukuze uxhume kudivayisi eshiwo.
Uhlelo lwe-root-side transporter example:
Uhlelo lomamukeli we-RX example:
khipha
Ukusebenza ne-Raspberry Pi
Ukusebenzisa le mod ku-Raspberry Pi nakho kulula! Xhuma iphinikhodi ngayinye yale mojula ye-RF kuphinikhodi ehambisanayo ye-RX/TX ku-Raspberry Pi, futhi ungakwazi ukufunda nokubhalela ngokuqondile iphinikhodi ye-RX/TX. Isetshenziswa ngendlela efanayo ne-UART yendabuko. Isibalo esilandelayo sibonisa indlela yokuxhumana phakathi kwe-Raspberry Pi kanye nemojula ye-MUARTO-B Root, uhlangothi lwedivayisi lucishe lufane kodwa ukuxhumana kwe-ID0 ne-ID1 akudingekile.
Example yohlelo:
Itholakalela izinhlangothi zombili zokudlulisa nokwamukela
Xhuma inzwa
Uma inzwa yakho isekela isixhumi esibonakalayo se-UART futhi izinga le-Baud lingu-9,600, ungakwazi ukuxhuma ngokuqondile kule mojula ngokushesha futhi ngokungenabuhlungu uthuthukise inzwa yokusebenza engenantambo. Izinzwa ezilandelayo ezingu-63 PM2.5 zithathwa njenge-example, bheka indlela yokuxhuma elandelayo
Singasebenzisa ibhodi eliyinhloko kungaba i-Arduino noma i-Raspberry Pi) futhi ungasebenzisa njengemodi evamile ye-UART enezintambo ukuze ufunde idatha ye-PM2.5 evela ku-G3. Siyakuhalalisela! I-G3 ithuthukisiwe ukuze ibe namandla okudlulisa okungenantambo i-PM2.5 sensing module.
Sebenzisa amachweba ayi-10
Imojula ye-MUARTO-B inikeza isethi yamachweba angu-l0 avumela ukuthi udlulise imiyalo yokuvula/ukuvala ngaphandle kwentambo, futhi lokhu kusetha ama-Ports akukhawulelwe ekudluliselweni noma ekutholeni ukuphela kwemojula, futhi zombili iziphetho zingakwazi ukulawulana. Inqobo nje uma ushintsha ivolumutage yephinikhodi engu-IN kunoma yisiphi isiphetho, uzoshintsha ivolumu yokuphumayotage yephinikhodi yokuphuma ngakolunye uhlangothi ngokuhambisana. Sicela ubheke ukusetshenziswa okulandelayoample ukuchaza indlela yokusebenzisa i-10 Port ukulawula ukude inkinobho ye-LED ye-switch.
