Kushandisa sei
Mhando dzese dzemabhodhi ekuvandudza uye maMCU anotsigira iyo UART yekutaurirana interface inogona kushandisa iyi module zvakananga, uye hapana chikonzero chekuisa mamwe madhiraivha kana mapurogiramu eAPI.
Seta Root uye Zvishandiso
Iyo yechinyakare wired TTL ndeye 1 kusvika 1 kutapurirana, iyo RFLINK-UART isina waya UART transmission module ichatsigira 1-to-multiple mhando, default Root terminal (#0) mushure mekubatisa nemudziyo (#1) yakabatana kana uine imwe. ine nhamba Mudziyo (#2~# 4). Iwe unogona kusarudza akasiyana mudziyo wedivi raunoda kubatanidza kwairi kuburikidza neID0 uye ID1 pini padivi remidzi. Nezve ID0/ID1 musanganiswa wekusarudza mudziyo, ndapota tarisa patafura iri pazasi
| Mudziyo 1 (#1) | Mudziyo 2 (#2) | Mudziyo 3 (#3) | Mudziyo 4 (#4) | |
| ID0 pini | HIGH | HIGH | LOW | LOW |
| ID1 pini | HIGH | LOW | HIGH | LOW |
ID0, ID1 pin ndeye default HIGH, ichange iri LOW kuburikidza nekubatanidza pasi.
Cherechedza: Device side inofanira kuiswa kune inodiwa nhamba yemudziyo zvichienderana nekutanga,
mudzi uchasarudza mudziyo wakanangwa kuburikidza netafura imwechete.
Unogona kusarudza mudziyo wakasiyana kuendesa meseji kuburikidza neID0 uye ID1 yemidzi, kazhinji inosunga ID0 kana/uye ID1 kuGND. Kupfuura izvozvo, iyo mudzi wedivi unogona zvakare kutumira Yakaderera / Yakakwirira chiratidzo kuburikidza neIO pini kusarudza iyo yakanangwa mudziyo panhunzi.
For example, mumufananidzo uri pazasi, Arduino Nano inosarudza Chishandiso chekubatanidza kuburikidza neD4 uye D5 pini.
Mushure mekutumira inoenderana Yepamusoro / Yakaderera chiratidzo kune ID0 uye ID1 pini, iyo
Root terminal inozokanganisa kutapurirana neyekare yekubatanidza yekupedzisira (kureva, kumisa kutapurirana uye kugamuchira neiyo yekare yekubatanidza yekupedzisira). Uye mirira iyo Yakaderera siginecha kubva kuID_Lat pini kuti uchinje kune nyowani yekubatanidza.
Tanga kutumira / kugamuchira mameseji nekubatanidza kutsva
Mushure mekutumira chinongedzo chenhamba yechiratidzo kuburikidza neID0, ID1, yese transection pakati pemudzi uye yazvino yakabatana mudziyo ichamiswa. Iyo itsva transection haizotanga kusvika watumira LOW siginecha yeID_Lat inokwana 3ms.
Kune matatu makesi ekushandisa eArduino, Raspberry Pi uye masensa.
Kushanda neArduino
Pamusoro pekushandisa Arduino's Hardware TX/RX ports zvakananga, iyi module inotsigirawo software serials, saka inogona Kushandisa mune software yakateedzerwa UART kudzivirira kubata iyo yemuviri UART interface.
Anotevera example iri kubatanidza D2 uye D3 kuTX uye iyo Root divi re
RFLINK-UART module kuburikidza nesoftware serial RX, D7, D8 ndiwo mapini anoseta kubatana kune mudziyo, uye D5 inoshandiswa seyo ok toggle pini. Kuburikidza nemirayiridzo yeArduino dhijitariNyora zvinobuda ZVINO kana HIGH zveD7, D8 uye D5 mapini Tinogona kuwana kugona kwekubatanidza zvine simba kumidziyo yakasiyana.

Kushanda neRaspberry Pi
Kushandisa iyi mod paRaspberry Pi zvakare iri nyore nyore! Mapini eRFLINKUART module akabatana kune anowirirana eRaspberry Pi semu ex.ample yeArduino pamusoro. Mune mamwe mazwi, unogona kuverenga nekunyora zvakananga kuRX/TX pini uye tsanangura mudziyo wekubatanidza, senge UART yechinyakare.
Mufananidzo unotevera unoratidza nzira yekubatanidza pakati peRot-side
Raspberry Pi uye RFLINK-UART module, uye nzira yekubatanidza yeChidimbu inopera yakangofanana, asi iyo ID_ Iyo Lat pini haidi kubatana, uye ID0 neID1 zvinoiswa kune dzakasiyana ID nhamba zvichienderana nezvinodiwa. .
Exampchirongwa chepurogiramu:
Iyo transmitter inodzokorodza kuendesa ruzivo kune mudziyo #3 uye mudziyo #1
Receiver: Uyu exampLe iri nyore kugamuchira
Kubatanidza zvakananga ne sensor
Kana sensor yako ichitsigira UART interface uye iyo Baud rate inotsigira 9,600 kana
19,200 , ipapo unokwanisa kuibatanidza zvakananga kudivi remudziyo reRFLINK-UART module, uye iwe unogona kukurumidza uye usingarwadze kuisimudza Wireless function sensor zvakare. Iyo inotevera G3 PM2.5 sensor inotorwa se example, tarisa kune inotevera nzira yekubatanidza
Tevere, ndapota gadzirira bhodhi rekuvandudza (kungava Arduino kana Raspberry Pi) kuti
batanidza RO yeRFLINK-UART module Kudivi reOt, unogona kuverenga iyo G3 kutapurirana mune yakajairika UART nzira PM2.5 data, makorokoto, iyo G3 yakakwidziridzwa kuita PM2.5 inonzwa module ine isina waya yekutapurirana masimba.
Shandisa IO Ports
Iyo RFLINK-UART module inopa seti yeIO ports inokubvumira kuti uendese pa / kudzima mirairo isina waya, uye iyi seti Io Ports haina kuganhurirwa kune kutapurirana kana kugamuchira kupera kwemodule, uye migumo miviri inogona kudzora mumwe nemumwe. Chero ukashandura voltage yeIN chiteshi kune chero kumagumo, iwe unoshandura inobuda voltage yeOut port kune imwe magumo synchronously. Ndokumbira utarise kune inotevera kushandiswa example kutsanangura mashandisiro eIO Port kudzora kure switch ye LED girobhu.
