I-ARDUINO RFLINK-UART Wireless UART Transmission Module
Ulwazi Lomkhiqizo
I-RFLINK-UART Wireless UART Transmission Module iyimojuli ethuthukisa i-UART enezintambo iye ekudluliseni kwe-UART okungenantambo ngaphandle komzamo wokubhala ikhodi noma ihadiwe. Imojuli iqukethe isiphetho esisodwa sempande futhi idivayisi efika kwezine iphetha ngesethi yezimbobo ze-I/O. Umthamo wokusebenzatage isukela ku-3.3V iye ku-5.5V, kanti imvamisa ye-RF isukela ku-2400MHz ukuya ku-2480MHz. Ibanga lokudlulisela liphakathi kuka-80 kuya ku-100m endaweni evulekile, futhi izinga lokudlulisela lingama-250Kbps. Imojula isekela ukudluliswa kwe-1-to-1 noma 1-to-multiple (kufika kokune).

Setha Umsuka Namadivayisi
Zonke izinhlobo zamabhodi okuthuthukisa kanye nama-MCU asekela isixhumi esibonakalayo sokuxhumana se-UART angasebenzisa le moduli ngokuqondile, futhi asikho isidingo sokufaka abashayeli abengeziwe noma izinhlelo ze-API. Imojula yokudlulisa engenantambo ye-RFLINK-UART ye-UART isekela uhlobo olu-1 kuya kuningi, itheminali ye-Root ezenzakalelayo (#0) ngemva kokukhanyisa ngedivayisi (#1) ixhunyiwe uma unenye Idivayisi enenombolo (#2~#4). Ungakhetha izinhlangothi ezihlukene zedivayisi ofuna ukuxhuma kuzo usebenzisa i-ID0 namaphinikhodi we-ID1 ohlangothini lwempande.
Ngenhlanganisela ye-ID0/ID1 yokukhetha idivayisi, bheka ithebula elingezansi:
| Idivayisi 1 (#1) | Idivayisi 2 (#2) | Idivayisi 3 (#3) | Idivayisi 4 (#4) |
|---|---|---|---|
| ID0 pin: HIGH ID1 pin: HIGH |
ID0 pin: HIGH Iphinikhodi ye-ID1: PHANSI |
Iphinikhodi ye-ID0: PHANSI ID1 pin: HIGH |
Iphinikhodi ye-ID0: PHANSI Iphinikhodi ye-ID1: PHANSI |
Uhlangothi lwedivayisi kufanele lusethwe enombolweni yedivayisi edingekayo ngokusho kokuqala, impande izokhetha idivayisi eqondiwe ngethebula elifanayo. Ungakhetha idivayisi ehlukile yokudlulisa umlayezo nge-ID0 ne-ID1 yempande, ngokuvamile ubophe i-ID0 noma/kanye ne-ID1 ku-GND. Ngaphezu kwalokho, uhlangothi lwempande lungaphinda luthumele isignali ephansi/ePhezulu ngephinikhodi ye-IO ukuze ukhethe idivayisi eqondiwe empukaneniampfuthi, esithombeni esingezansi, i-Arduino Nano ikhetha Idivayisi ukuze ixhumeke ngezikhonkwane ze-D4 ne-D5. Ngemva kokuthumela isignali ehambisanayo Ephakeme/Ephansi ku-ID0 kanye nezikhonkwane ze-ID1, i-Root terminal izophazamisa ukudluliswa kwesiphetho esidala sokuxhuma (okungukuthi, ukumisa ukudlulisela nokwamukela ngesiphetho esidala sokuxhuma). Bese ulinda isignali ephansi esuka kuphinikhodi ye-ID_Lat ukuze ushintshele ekuxhumekeni okusha.
I-RFLINK-UART Wireless UART Transmission Module iyimojuli esebenziseka kalula ethuthukisa ngokushesha nangokungenabuhlungu i-UAR enezintambo ekudluliseni kwe-UAR okungenantambo. Ngaphezu kwalokho , kukhona isethi yembobo ye-I/O lapho , ngakho awudingi umzamo wokubhala ikhodi nehadiwe ukwenza amaswishi e-IO alawulwe kahle ukude.
Ukubukeka Kwemojula Nobukhulu
Imojula ye-RFLINK-UART iqukethe ukuphela kwempande eyodwa (kwesobunxele) kuze kufike esiphethweni seDivaysi ezine (ngakwesokudla kwesithombe esingezansi, ingase ifakwe izinombolo ukusuka ku-1 kuye ku-4), kokubili kubukeka ngaphandle okufanayo, kungabonakala. ngelebula elingemuva . Njengoba kuboniswe ngezansi, i-ID Yeqembu yemojuli ye-RFLINK-UART ithi 0001 futhi i-BAUD ingu-9600.

Isetshenziswa kanjani
Zonke izinhlobo zamabhodi okuthuthukisa kanye nama-MCU asekela isikhombimsebenzisi sokuxhumana se-UART angasebenzisa le moduli ngokuqondile, futhi asikho isidingo sokufaka abashayeli abengeziwe noma izinhlelo ze-API.
Setha Umsuka Namadivayisi
I-TTL enentambo evamile ingukudlulisa oku-1 kuye ku-1, imojula ye-RFLINK-UART yokudlulisa engenantambo ye-UART izosekela uhlobo olu-1 ukuya ku-multiple, ukuphela okuzenzakalelayo kwe-Root (#0) ngemva kokukhanyisa ngedivayisi (#1) ixhunyiwe uma unolunye. Idivayisi enezinombolo (#2~# 4). Ungakhetha uhlangothi lwedivayisi oluhlukile ofuna ukuxhuma kulo usebenzisa i-ID0 namaphinikhodi we-ID1 ohlangothini lwempande. Ngenhlanganisela ye-ID0/ID1 yokukhetha idivayisi, sicela ubheke ithebula elingezansi.
I-ID0, iphinikhodi ye-ID1 zingu-HIGH okuzenzakalelayo, zizoba PHANSI ngokuxhuma phansi.
Qaphela: Uhlangothi lwedivayisi kufanele lusethelwe kunombolo yedivayisi edingekayo ngokuya kokuqala, impande izokhetha idivayisi eqondiwe ngethebula elifanayo.
Ungakhetha idivayisi ehlukile yokudlulisa imilayezo nge-ID0 ne-ID1 yempande, ngokuvamile ehlanganisa i-ID0 noma/kanye ne-ID1 ku-GND. Ngaphezu kwalokho, uhlangothi lwempande lungaphinda luthumele isignali Ephansi/Ephezulu ngephinikhodi ye-IO ukuze ukhethe idivayisi eqondiwe empukaneni. Okwesiboneloampfuthi, esithombeni esingezansi, i-Arduino Nano ikhetha Idivayisi ukuze ixhumeke ngezikhonkwane ze-D4 ne-D5.
Ngemva kokuthumela isignali ehambisanayo Ephakeme/Ephansi ku-ID0 kanye nezikhonkwane ze-ID1, i-Root terminal izophazamisa ukudluliswa kwesiphetho esidala sokuxhuma (okungukuthi, ukumisa ukudlulisela nokwamukela ngesiphetho esidala sokuxhuma). Futhi ulinde isignali ephansi esuka kuphinikhodi ye-ID_Lat ukuze ushintshele ekuxhumekeni okusha.
Qala ukudlulisa/ukwamukela imilayezo ngoxhumano olusha
Ngemva kokuthumela isignali yenombolo yedivayisi eqondiwe nge-ID0, ID1, konke ukunqamula phakathi kwempande nedivayisi yamanje exhunyiwe kuzomiswa. I-transection entsha ngeke iqale uze uthumele isignali EPHANSI ye-ID_Lat okungenani engu-3ms.
Kunamacala amathathu okusetshenziswa kwe-Arduino, i-Raspberry Pi, nezinzwa.
Ukusebenza ne-Arduino
Ngaphezu kokusebenzisa izimbobo zehadiwe ze-Arduino ze-TX/RX ngokuqondile, le mojula futhi isekela izinhlelo zesofthiwe, ngakho-ke ingasebenzisa i-UART elingisa isofthiwe ukugwema ukusebenzisa isixhumi esibonakalayo se-UART. I-ex elandelayoampi-le ixhuma i-D2 ne-D3 ku-TX kanye nohlangothi lwe-Root lwemojula ye-RFLINK-UART ngokusebenzisa i-serial yesofthiwe i-RX, i-D7, i-D8 izikhonkwane ezibeka uxhumano kudivayisi, futhi i-D5 isetshenziswa njengephinikhodi yokuguqula ok. Ngeziyalezo ze-Arduino, okuphumayo kwedijithaliBhala OKUPHANSI noma KUPHANSI kwezikhonkwane ze-D7, D8 kanye ne-D5 Singakwazi ukuzuza ikhono lokuxhuma ngamandla kumadivayisi ahlukene.
Example yohlelo lokuthutha oluseceleni kwezimpande:

Ukusebenza ne-Raspberry Pi
Ukusebenzisa le mod ku-Raspberry Pi nakho kulula! Izikhonkwane zemojula ye-RFLINK-UART zixhunywe kulawo ahambisanayo e-Raspberry Pi njengaku-ex.ample ye-Arduino ngenhla. Ngamanye amazwi, ungafunda futhi ubhale ngqo kuphinikhodi ye-RX/TX futhi ucacise idivayisi ozoyixhuma, njenge-UART evamile. Isibalo esilandelayo sibonisa indlela yokuxhumana phakathi kwe-Root-side Raspberry Pi kanye nemojuli ye-RFLINK-UART, futhi indlela yokuxhuma yesiphetho Sedivayisi iyafana ngokuyisisekelo, kodwa ID_ Iphinikhodi ye-Lat ayidingi ukuxhunywa, kanye ne-ID0 kanye ne-ID1 isethwe ezinombolweni zomazisi ezihlukene kuye ngezidingo.
Exampuhlelo:
I-transmitter idlulisela ngokuphindaphindiwe ulwazi kudivayisi #3 nakudivayisi #1
Umamukeli: Lesi example kuyinto elula ukuthola
Ukuxhuma okuqondile ngenzwa
Uma inzwa yakho isekela isixhumi esibonakalayo se-UART futhi izinga le-Baud lisekela 9,600 noma 19,200 , ungakwazi ukuyixhuma ngokuqondile ohlangothini lwedivayisi lwemojuli ye-RFLINK-UART, futhi ungakwazi ukuyithuthukisa ngokushesha nangokungenabuhlungu Inzwa yokusebenza okungenantambo futhi. Inzwa elandelayo ye-G3 PM2.5 ithathwa njenge-example, bheka indlela yokuxhuma elandelayo
Okulandelayo, sicela ulungise ibhodi lokuthuthukisa (okungaba i-Arduino noma i-Raspberry Pi) ukuxhuma i-RO yemojula ye-RFLINK-UART Ngakolunye uhlangothi, ungafunda ukudluliswa kwe-G3 ngendlela evamile yedatha ye-UART ye-PM2.5, siyakuhalalisela, i-G3 ine ithuthukiswe yaba imojula yezinzwa ye-PM2.5 enamandla okudlulisa okungenantambo.
Sebenzisa i-IO Ports
Imojula ye-RFLINK-UART inikeza isethi yezimbobo ze-IO ezikuvumela ukuthi udlulise imiyalo yokuvula/ukuvala ngaphandle kwentambo, futhi le sethi ye-Io Ports ayikhawulelwe ekudluliselweni noma ekutholeni ukuphela kwemojula, futhi zombili iziphetho zingakwazi ukulawulana. Inqobo nje uma ushintsha ivolumutagembobeni engu-IN kunoma yisiphi isiphetho, uzoshintsha ivolumu yokuphumayotage ye-Out port ngakolunye uhlangothi ngokuvumelanisa. Sicela ubheke ukusetshenziswa okulandelayoample ukuchaza indlela yokusebenzisa i-IO Port ukulawula ukude inkinobho ye-LED ye-switch.
