ARDUINO RFLINK-UART Wireless UART Transmission Modyuli
Ulwazi lweMveliso
I-RFLINK-UART Wireless Transmission Module yimodyuli ephucula i-UART enengcingo ukuya kuthumelo lwe-UART olungenazingcingo ngaphandle komzamo wokubhala iikhowudi okanye ihardware. Imodyuli iqulathe isiphelo sengcambu enye kwaye ukuya kuthi ga kwisixhobo esine ekupheleni ngeseti yezibuko ze-I/O. Umthamo wokusebenzatage ukusuka kwi-3.3V ukuya kwi-5.5V, kunye ne-RF frequency ranges ukusuka kwi-2400MHz ukuya kwi-2480MHz. Umgama wothumelo ujikeleze i-80 ukuya kwi-100m kwindawo evulekileyo, kwaye izinga lokuhambisa liyi-250Kbps. Imodyuli ixhasa i-1-to-1 okanye i-1-to-multiple (ukuya kwezine) ukuhanjiswa.

Imiyalelo yokusetyenziswa kwemveliso
Cwangcisa ingcambu kunye nezixhobo
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. I-RFLINK-UART imodyuli yothumelo ye-UART engenangcingo ixhasa u-1-ukuya-udidi oluninzi, i-terminal yeNqaku engagqibekanga (#0) emva kokuvula amandla ngesixhobo (#1) iqhagamshelene ukuba unesinye isixhobo esinenombolo (#2~#4). Unokukhetha amacala ahlukeneyo esixhobo ofuna ukuqhagamshela kuwo nge-ID0 kunye nezikhonkwane ze-ID1 kwicala leengcambu.
Kudibaniso lwe-ID0/ID1 lokukhetha isixhobo, bhekisa kwitheyibhile engezantsi:
| Isixhobo 1 (#1) | Isixhobo 2 (#2) | Isixhobo 3 (#3) | Isixhobo 4 (#4) |
|---|---|---|---|
| ID0 pin: PHEZULU ID1 pin: PHEZULU |
ID0 pin: PHEZULU ID1 pin: PHANTSI |
ID0 pin: PHANTSI ID1 pin: PHEZULU |
ID0 pin: PHANTSI ID1 pin: PHANTSI |
Icala lesixhobo kufuneka limiselwe kwinombolo yesixhobo efunekayo ngokutsho kuqala, ingcambu iya kukhetha isixhobo ekujoliswe kuso ngetafile enye. Unokukhetha isixhobo esahlukileyo ukudlulisa umyalezo nge-ID0 kunye ne-ID1 yeengcambu, ngokuqhelekileyo ubophe i-ID0 okanye/kunye ne-ID1 kwi-GND. Ngaphezu koko, icala lengcambu lingathumela uphawu oluPhantsi/ oluPhezulu nge-IO pin ukukhetha isixhobo ekujoliswe kuso kubhabho Kuba ex.ample, kumzobo ongezantsi, Arduino Nano ukhetha Isixhobo ukuqhagamshela nge D4 kunye D5 izikhonkwane. Emva kokuthumela isignali ehambelanayo ePhakamileyo / ephantsi kwi-ID0 kunye ne-ID1 izikhonkwane, i-terminal ye-Root iya kuphazamisa ukuhanjiswa kunye nokuphela koxhumo oludala (oko kukuthi, ukuyeka ukuhanjiswa kunye nokufumana kunye nokuphela koxhumo oludala). Kwaye linda isignali ePhantsi ukusuka kwi-ID_Lat pin ukutshintshela kuqhagamshelwano olutsha.
I-RFLINK-UART Wireless Transmission Module yimodyuli ekulula ukuyisebenzisa ephucula ngokukhawuleza nangentlungu eneengcingo ze-UAR ukuya kuthumelo lwe-UAR engenazingcingo. Ngaphezu koko , kukho uluhlu lwe I/O izibuko apho , ngoko awudingi mzamo wokubhala iikhowudi 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 yi-9600.

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.
I-ID0, i-pin ye-ID1 ayigqibekanga PHAKAMILEYO, ziya kuba PHANTSI ngokudibanisa emhlabeni.
Phawula: Icala lesixhobo kufuneka limiselwe kwinani elifunekayo lesixhobo ngokutsho kuqala, ingcambu iya kukhetha isixhobo ekujoliswe kuso ngetafile enye.
Ungakhetha isixhobo esahlukileyo ukudlulisa imiyalezo nge-ID0 kunye ne-ID1 yengcambu, ngokuqhelekileyo idibanisa 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 isignali ehambelanayo ePhakamileyo / ephantsi kwi-ID0 kunye ne-ID1 izikhonkwane, i-terminal ye-Root iya kuphazamisa ukuhanjiswa kunye nokuphela koxhumo oludala (oko kukuthi, ukuyeka ukuhanjiswa kunye nokufumana kunye nokuphela koxhumo oludala). 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 nezivamvo.
Ukusebenza kunye neArduino
Ukongeza ekusebenziseni i-hardware ye-Arduino ye-TX/RX izibuko ngokuthe ngqo, le modyuli ikwaxhasa uthotho lwesoftware, ngoko inokuSebenzisa kwi-UART eyenziwe yesoftware ukunqanda ukuhlala kujongano lomzimba lwe-UART. Le ex ilandelayoample idibanisa i-D2 kunye ne-D3 kwi-TX kunye necala leNgcambu ye-RFLINK-UART imodyuli ngokusebenzisa i-serial ye-serial RX, i-D7, i-D8 yizikhonkwane ezibeka uxhulumaniso kwisixhobo, kwaye i-D5 isetyenziswa njenge-pin ok toggle. Ngokusebenzisa imiyalelo ye-Arduino, i-digitalBhala iziphumo eziphantsi okanye eziPhakamileyo ze-D7, i-D8 kunye ne-D5 izikhonkwane Singakwazi ukufezekisa ukukwazi ukudibanisa ngamandla kwizixhobo ezahlukeneyo.
Example yenkqubo yothutho yecala lengcambu:

phumeza
Ukusebenza kunye neRaspberry Pi
Ukusebenzisa le mod kwiRaspberry Pi nako kulula ngokufanelekileyo! Izikhonkwane zemodyuli yeRFLINK-UART 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 mzobo ulandelayo ubonisa indlela yodibaniso phakathi kwe Root-side Raspberry Pi kunye ne RFLINK-UART imodyuli, kwaye indlela yoqhagamshelo lweSixhobo ekupheleni iyafana, kodwa ID_ I-pin yeLat ayifuni kudityaniswa, kwaye ID0 kunye ne-ID1 zisetelwe kwiinombolo zezazisi 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 isivamvo sakho sixhasa ujongano lwe-UART kunye nezinga le-Baud lixhasa i-9,600 okanye i-19,200, ngoko ungayidibanisa ngokuthe ngqo kwicala lesixhobo se-RFLINK-UART imodyuli, kwaye unokuyiphucula ngokukhawuleza nangokungenantlungu kuyo Wireless function sensor too. Le ilandelayo inzwa ye-G3 PM2.5 ithathwa njenge-example, bhekisa kule ndlela ilandelayo yoqhagamshelwano
Okulandelayo, nceda ulungiselele ibhodi yophuhliso (ingaba i-Arduino okanye i-Raspberry Pi) ukudibanisa i-RO ye-modyuli ye-RFLINK-UART Kwi-Ot side, unokufunda ukuhanjiswa kwe-G3 kwi-UART jikelele yedatha ye-PM2.5, halala, i-G3 ine iphuculwe yaya kutsho kwimodyuli ye-PM2.5 ekwaziyo ukuhambisa ngaphandle kwamacingo.
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.
