I-RFLINK-UART Wireless UART Transmission Module Manual
I-RFLINK-UART Wireless UART Transmission Module iyimojuli esebenziseka kalula ethuthukisa ngokushesha nangokungenabuhlungu i-UART enezintambo ekudluliseni kwe-UART 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) futhi kufike ekugcineni kweDivaysi ezine (ngakwesokudla kwesithombe esingezansi, kungase kufakwe izinombolo ukusuka ku-1 kuye ku-4), kokubili kubukeka ngaphandle okufanayo, kungabonakala. ngelebula elingemuva .
Njengoba kukhonjisiwe ngezansi, i-ID Yeqembu yemojuli ye-RFLINK-UART ithi 0001 kanye ne-BAUD
Izici zemojuli

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 enenombolo (#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
| Idivayisi 1 (#1) | Idivayisi 2 (#2) | Idivayisi 3 (#3) | Idivayisi 4 (#4) | |
| ID0 iphini | PHEZULU | PHEZULU | PHANSI | PHANSI |
| ID1 iphini | PHEZULU | PHANSI | PHEZULU | PHANSI |
I-ID0, iphinikhodi ye-ID1 zingu-HIGH okuzenzakalelayo, zizoba PHANSI ngokuxhuma phansi.
Qaphela: Uhlangothi lwedivayisi kufanele lusethwe enombolweni yedivayisi edingekayo ngokuya kuqala,
impande izokhetha idivayisi eqondiwe ngethebula elifanayo.
Ungakhetha idivayisi ehlukile ukuze udlulise 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 empukaneni.
Okwesiboneloampfuthi, esithombeni esingezansi, i-Arduino Nano ikhetha Idivayisi ukuze ixhumeke ngezikhonkwane ze-D4 ne-D5.
Ngemva kokuthumela isignali ehambisanayo Ephakeme/Ephansi kumaphini we-ID0 ne-ID1, i
Itheminali yezimpande izophazamisa ukuhanjiswa ngesiphetho 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 iphinde isekele izinhlelo zesofthiwe, ngakho-ke ingasebenzisa isofthiwe elingisiwe ye-UART ukugwema ukusebenzisa isixhumi esibonakalayo se-UART.

Imojuli ye-RFLINK-UART ngokusebenzisa i-serial yesofthiwe i-RX, i-D7, i-D8 izikhonkwane ezisetha uxhumo kudivayisi, futhi i-D5 isetshenziswa njengephinikhodi yokuguqula ok. Ngeziyalezo ze-Arduino zedijithaliBhala okuphumayo OKUPHANSI noma KUPHANSI kumaphini we-D7, D8 kanye ne-D5 Singakwazi ukufeza ikhono lokuxhuma ngamandla kumadivayisi ahlukene.

Ukusebenza ne-Raspberry Pi
Ukusebenzisa le mod ku-Raspberry Pi nakho kulula! Izikhonkwane zemojuli ye-RFLINKUART 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.
Umfanekiso olandelayo ubonisa indlela yokuxhuma phakathi kwe-Root-side
I-Raspberry Pi kanye nemojula ye-RFLINK-UART, kanye nendlela yokuxhuma yesiphetho Sedivayisi ngokuyisisekelo iyafana, kodwa ID_ Iphinikhodi yesi-Lat ayidingi ukuxhunywa, futhi i-ID0 ne-ID1 zisethelwe ezinombolweni ezihlukene ze-ID 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 i-9,600 noma
19,200 , bese 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 (kungaba i-Arduino noma i-Raspberry Pi) ukuze
xhuma i-RO yemojula ye-RFLINK-UART Ngakolunye uhlangothi, ungafunda ukudluliswa kwe-G3 ngedatha evamile ye-UART ngendlela ye-PM2.5, siyakuhalalisela, i-G3 ithuthukisiwe yaba imojula yenzwa 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.
