RFLINK-UART Wireless UART Transmission Module Manual
I-RFLINK-UART Wireless Transmission Module yimodyuli ekulula ukuyisebenzisa ephucula ngokukhawuleza nangeentlungu iUART enengcingo ukuya kuthumelo lwe-UART engenazingcingo. Ngaphezu koko , kukho uluhlu lwe I/O izibuko apho , ngoko awudingi mzamo wokubhala ikhowudi kunye nehardware ukwenza iiswitshi ze-IO zilawulwe kakuhle kude.
INkangeleko yeModyuli kunye neDimension
Imodyuli ye-RFLINK-UART iqulethe i-terminal enye yeengcambu (ekhohlo) kwaye ukuya kuthi ga kwisiphelo seSixhobo esine (kwicala lasekunene lomzobo ongezantsi, unokubalwa ukusuka ku-1 ukuya ku-4), ezi zimbini zijongeka ngaphandle ziyafana, zinokuchongwa. ngeleyibhile engasemva .
Njengoko kuboniswe ngezantsi, i-ID yeQela lemodyuli ye-RFLINK-UART yi-0001 kunye ne-BAUD

Kusetyenziswa kwanjani
Zonke iintlobo zeebhodi zophuhliso kunye nee-MCU ezixhasa i-interface yonxibelelwano ye-UART ingasebenzisa le modyuli ngokuthe ngqo, kwaye akukho mfuneko yokufaka abaqhubi abongezelelweyo okanye iinkqubo ze-API.
Cwangcisa ingcambu kunye nezixhobo
TTL eneentambo zemveli yi-1 ukuya ku-1 usasazo, i-RFLINK-UART imodyuli yothumelo ye-UART engenangcingo iya kuxhasa uhlobo olu-1 ukuya kuninzi, olungagqibekanga lwe-Root terminal (#0) emva kombane ngesixhobo (#1) iqhagamshelene ukuba unomnye. inombolo Isixhobo (#2~# 4). Ungakhetha icala isixhobo ezahlukeneyo ofuna ukudibanisa ngokusebenzisa ID0 kunye ID1 izikhonkwane kwicala leengcambu. Kudibaniso lwe-ID0/ID1 lokukhetha isixhobo, nceda ubhekisele kwitheyibhile engezantsi
| Isixhobo 1 (#1) | Isixhobo 2 (#2) | Isixhobo 3 (#3) | Isixhobo 4 (#4) | |
| ID0 iphini | PHEZULU | PHEZULU | PHANTSI | PHANTSI |
| ID1 iphini | PHEZULU | PHANTSI | PHEZULU | PHANTSI |
I-ID0, i-pin ye-ID1 ayigqibekanga PHAKAMILEYO, ziya kuba PHANTSI ngokudibanisa emhlabeni.
Phawula: Icala lesixhobo kufuneka limiselwe kwinombolo yesixhobo efunekayo ngokokuqala,
ingcambu izakukhetha icebo letekeni ngetafile enye.
Unokukhetha isixhobo esahlukileyo sokudlulisa umyalezo nge-ID0 kunye ne-ID1 yeengcambu, ngokuqhelekileyo qhina i-ID0 okanye/kunye ne-ID1 kwi-GND. Ngaphezu koko, icala lengcambu lingathumela uphawu oluphantsi / oluPhezulu nge-IO pin ukukhetha isixhobo esijoliswe kuyo kwimpukane.
UmzekeloampLe, kumzobo ongezantsi, i-Arduino Nano ikhetha iSixhobo ukuqhagamshela nge-D4 kunye ne-D5 izikhonkwane.
Emva kokuthumela uphawu oluhambelanayo oluPhezulu / oluphantsi kwi-ID0 kunye ne-ID1 izikhonkwane, i
I-terminal ye-Root iya kuphazamisa ukuhanjiswa kunye nesiphelo soqhagamshelwano esidala (oko kukuthi, ukuyeka ukuhanjiswa kunye nokufumana kunye nesiphelo soqhagamshelwano esidala). Kwaye linda isignali ePhantsi esuka kwi-ID_Lat pin ukutshintshela kuqhagamshelwano olutsha.
Qala ukuthumela/ukufumana imiyalezo ngoqhagamshelwano olutsha
Emva kokuba uthumele isignali yenombolo yesixhobo ekujoliswe kuyo nge-ID0, i-ID1, konke ukunqumla phakathi kweengcambu kunye nesixhobo esiqhagamshelwe ngoku siya kunqunyanyiswa. Itransekshini entsha ayizukuqala de ube uthumele isignali ePHANTSI ye-ID_Lat ubuncinane 3ms.
Kukho iimeko ezintathu zokusetyenziswa kweArduino, iRaspberry Pi kunye nezinzwa.
Ukusebenza kunye neArduino
Ukongeza ekusebenziseni i-hardware ye-Arduino ye-TX/RX izibuko ngokuthe ngqo, le modyuli ikwaxhasa uthotho lwesoftware, ngoko inokuSebenzisa kwisoftware efanisiweyo ye-UART ukunqanda ukuhlala kujongano lwe-UART olubonakalayo.
Le ex ilandelayoample idibanisa i-D2 kunye ne-D3 ukuya kwi-TX kunye necala leNgcambu ye
Imodyuli ye-RFLINK-UART ngokusebenzisa i-serial ye-software ye-RX, i-D7, i-D8 zizikhonkwane ezibeka uxhulumaniso kwisixhobo, kwaye i-D5 isetyenziswa njenge-pin ok toggle. Ngokusebenzisa imiyalelo ye-Arduino yedijithaliBhala iziphumo ezi-PHANTSI okanye eziPhakamileyo ze-D7, i-D8 kunye ne-D5 izikhonkwane Sinokufikelela ukukwazi ukudibanisa ngokuguquguqukayo kwizixhobo ezahlukeneyo.

Ukusebenza kunye neRaspberry Pi
Ukusebenzisa le mod kwiRaspberry Pi nako kulula ngokufanelekileyo! Izikhonkwane zemodyuli yeRFLINKUART ziqhagamshelene nezihambelanayo zeRaspberry Pi njengakwi ex.ample ye Arduino ngasentla. Ngamanye amazwi, unokufunda kwaye ubhale ngokuthe ngqo kwi-RX/TX pin kwaye uchaze isixhobo sokudibanisa, njenge-UART yemveli.
Lo mfanekiso ulandelayo ubonisa indlela yoqhagamshelo phakathi kwe-Root-side
I-Raspberry Pi kunye ne-RFLINK-UART imodyuli, kunye nendlela yoqhagamshelo lweSixhobo ekupheleni iyafana, kodwa i-ID_ I-pin ye-Lat ayifuni kudityaniswa, kwaye i-ID0 kunye ne-ID1 zicwangciswe kwiinombolo ze-ID ezahlukeneyo ngokuxhomekeke kwiimfuno. .
Example nkqubo:
Isidlulisi sithumela ngokuphindaphindiweyo ulwazi kwisixhobo #3 kunye nesixhobo #1
Umamkeli: Lo exampLe yinto elula yokufumana
Ukudibanisa ngokuthe ngqo kunye nenzwa
Ukuba inzwa yakho ixhasa ujongano lwe-UART kunye nezinga le-Baud lixhasa i-9,600 okanye
19,200 , emva koko ungayidibanisa ngokuthe ngqo kwicala lesixhobo se-RFLINK-UART imodyuli, kwaye unokuyiphucula ngokukhawuleza nangentlungu engenazingcingo. Le ilandelayo inzwa ye-G3 PM2.5 ithathwa njenge-example, bhekisa kule ndlela ilandelayo yoqhagamshelwano
Okulandelayo, nceda ulungiselele ibhodi yophuhliso (nokuba Arduino okanye Raspberry Pi) ukuze
qhagamshela i-RO yemodyuli ye-RFLINK-UART Kwi-ot side, unokufunda ukuhanjiswa kwe-G3 kwi-UART jikelele ngendlela yedatha ye-PM2.5, sivuyisana naye, i-G3 iphuculwe kwimodyuli yokuva i-PM2.5 ene-wireless transmission capabilities.
Sebenzisa i-IO Ports
Imodyuli ye-RFLINK-UART inikezela ngeseti yeechweba ze-IO ezikuvumela ukuba udlulisele / uvale imiyalelo ngaphandle kwamacingo, kwaye le seti ye-Io Ports ayiphelelanga ekugqithiseni okanye ekufumaneni ukuphela kwemodyuli, kwaye zombini iziphelo zinokulawula omnye nomnye. Ngethuba nje utshintsha i-voltage ye INzibuko nakwesiphi na isiphelo, uyakutshintsha ivolthi yemvelisotage yeSibuko sangaphandle kwelinye isiphelo ngendlela ehambelanayo. Nceda bhekisa kusetyenziso olulandelayoample ukucacisa indlela yokusebenzisa IO Port ukulawula ukude switsha LED ibhalbhu.
