Kukhazikitsa Muzu ndi Zipangizo
Mitundu yonse ya matabwa a chitukuko ndi ma MCU omwe amathandiza mawonekedwe olankhulana a UART angagwiritse ntchito gawoli mwachindunji, ndipo palibe chifukwa choyika madalaivala owonjezera kapena mapulogalamu a API. The RFLINK-UART opanda zingwe UART kufala gawo amathandiza 1-kuti-ambiri mtundu, kusakhulupirika Muzu terminal (#0) pambuyo kuyatsa ndi chipangizo (#1) olumikizidwa ngati muli china nambala Chipangizo (#2~#4). Mutha kusankha mbali zosiyanasiyana za chipangizo zomwe mukufuna kulumikizana nazo kudzera pa ID0 ndi ma ID1 pamizu.
Pazophatikizira za ID0/ID1 za kusankha kwa chipangizo, onani tebulo ili m'munsili:
| Chipangizo 1 (#1) | Chipangizo 2 (#2) | Chipangizo 3 (#3) | Chipangizo 4 (#4) |
|---|---|---|---|
| ID0 pini: PAMULI ID1 pini: PAMULI |
ID0 pini: PAMULI Pini ya ID1: LOW |
Pini ya ID0: LOW ID1 pini: PAMULI |
Pini ya ID0: LOW Pini ya ID1: LOW |
Mbali ya chipangizocho iyenera kukhazikitsidwa ku nambala yofunikira ya chipangizo malinga ndi poyamba, muzu udzasankha chipangizo chandamale kudzera pa tebulo lomwelo. Mukhoza kusankha chipangizo chosiyana kusamutsa uthenga kudzera pa ID0 ndi ID1 ya muzu, kawirikawiri kumangiriza ID0 kapena/ndi ID1 ku GND. Kupitilira apo, mbali ya mizu imathanso kutumiza chizindikiro Chotsika / Chapamwamba kudzera pa pini ya IO kuti musankhe chipangizo chandamale pa ntchentche For ex.ample, mu chithunzi pansipa, Arduino Nano amasankha Chipangizo kuti agwirizane ndi D4 ndi D5 pini. Pambuyo potumiza chizindikiro chofanana cha High / Low ku ID0 ndi ID1 pini, Root terminal idzasokoneza kutumiza ndi mapeto akale a kugwirizana (ndiko kuti, kuyimitsa kutumiza ndi kulandira ndi mapeto akale ogwirizanitsa). Ndipo dikirani chizindikiro Chotsika kuchokera pa ID_Lat pin kuti musinthe kulumikizana kwatsopano.
RFLINK-UART Wireless UART Transmission Module ndi gawo losavuta kugwiritsa ntchito lomwe limakweza mawaya a UAR kupita kumayendedwe opanda zingwe a UAR. Kupitilira apo, pali doko la I/O pamenepo, chifukwa chake simufunika kuyesetsa kulikonse kuti mupange masiwichi a IO kuti aziyendetsedwa kutali.
Mawonekedwe a Module ndi Dimension
Gawo la RFLINK-UART lili ndi mizu imodzi (kumanzere) mpaka ku mapeto anayi a Chipangizo (kumanja kwa chithunzi pansipa, akhoza kuwerengedwa kuyambira 1 mpaka 4), awiriwa akuwoneka ofanana, amatha kudziwika. ndi chizindikiro chakumbuyo . Monga tawonetsera pansipa, Gulu la ID la gawo la RFLINK-UART ndi 0001 ndipo BAUD ndi 9600.

- MU→ Pin yolowetsa ya IO Port (On/Off kulandira).
- ID1, ID0→ Kupyolera mu kuphatikiza kwa HIGH/LOW kwa mapini awiriwa, Chipangizocho chitha kukhazikitsidwa ku manambala a chipangizocho. ID_Lat→ Phazi la Pin ili silikhudza Chipangizo.
Momwe mungagwiritsire ntchito
Mitundu yonse ya matabwa a chitukuko ndi ma MCU omwe amathandiza mawonekedwe olankhulana a UART angagwiritse ntchito gawoli mwachindunji, ndipo palibe chifukwa choyika madalaivala owonjezera kapena mapulogalamu a API.
Kukhazikitsa Muzu ndi Zipangizo
TTL yamtundu wamawaya ndi 1 mpaka 1 kufala, gawo la RFLINK-UART lopanda zingwe la UART limathandizira mtundu wa 1-to-multiple, default Root terminal (#0) mutatha kuyatsa ndi chipangizo (#1) cholumikizidwa ngati muli ndi china. Nambala Chipangizo (#2~# 4). Mutha kusankha mbali zosiyanasiyana za chipangizo zomwe mukufuna kulumikizana nazo kudzera pa ID0 ndi ma ID1 pamizu. Pazophatikiza za ID0/ID1 za kusankha kwa chipangizo, chonde onani tebulo ili m'munsimu.
ID0, pini ya ID1 ndizosasintha KWAMBIRI, zidzakhala LOW polumikiza pansi.
Zindikirani: Mbali ya chipangizocho iyenera kukhazikitsidwa ku nambala yofunikira ya chipangizo monga choyamba, muzu udzasankha chipangizo chandamale kudzera pa tebulo lomwelo.
Mukhoza kusankha chipangizo osiyana kusamutsa mauthenga kudzera ID0 ndi ID1 muzu, kawirikawiri zingwe ID0 kapena/ndi ID1 kuti GND. Kupitilira apo, mbali ya mizu imatha kutumizanso chizindikiro Chotsika / Chapamwamba kudzera pa pini ya IO kuti musankhe chipangizo chandamale pa ntchentche. Za example, pachithunzi pansipa, Arduino Nano amasankha Chipangizo kuti chilumikizane ndi D4 ndi D5 pini.
Pambuyo potumiza chizindikiro chofanana cha High / Low ku ID0 ndi ID1 pini, Root terminal idzasokoneza kutumiza ndi mapeto akale a kugwirizana (ndiko kuti, kuyimitsa kutumiza ndi kulandira ndi mapeto akale ogwirizanitsa). Ndipo dikirani chizindikiro Chotsika kuchokera pa ID_Lat pin kuti musinthe kulumikizana kwatsopano.
Yambani kutumiza/kulandira mauthenga ndi kulumikizana kwatsopano
Mukatumiza chizindikiro cha nambala ya chipangizocho kudzera pa ID0, ID1, njira zonse pakati pa muzu ndi chipangizo cholumikizidwa pano zidzayimitsidwa. Kudutsa kwatsopano sikuyamba mpaka mutatumiza chizindikiro LOW cha ID_Lat osachepera 3ms.
Pali njira zitatu zogwiritsira ntchito Arduino, Raspberry Pi, ndi masensa.
Kugwira ntchito ndi Arduino
Kuphatikiza pa kugwiritsa ntchito madoko a Arduino a TX/RX mwachindunji, gawoli limathandiziranso mapulogalamu apulogalamu, kotero limatha Kugwiritsa ntchito mu UART yopangidwa ndi mapulogalamu kuti mupewe kukhala ndi mawonekedwe a UART. Example ikulumikiza D2 ndi D3 ku TX ndi Muzu mbali ya RFLINK-UART gawo kudzera pulogalamu siriyo RX, D7, D8 ndi mapini kuti kulumikiza ku chipangizo, ndipo D5 ntchito ngati ok toggle pini. Kupyolera mu malangizo a Arduino, digitoWrite zotsatira LOW kapena HIGH kwa D7, D8 ndi D5 pini Tikhoza kukwaniritsa luso logwirizanitsa mwamphamvu ku zipangizo zosiyanasiyana.
Exampndi pulogalamu yoyendetsa mbali imodzi:

Kugwira ntchito ndi Raspberry Pi
Kugwiritsa ntchito mod iyi pa Raspberry Pi ndikosavuta! Zikhomo za module ya RFLINK-UART zimalumikizidwa ndi zofanana za Raspberry Pi monga momwe zilili kale.ample ya Arduino pamwamba. Mwanjira ina, mutha kuwerenga ndikulemba mwachindunji ku pini ya RX/TX ndikutchula chipangizocho kuti mulumikizane, monga UART yachikhalidwe. Chithunzi chotsatirachi chikuwonetsa njira yolumikizirana pakati pa Root-side Raspberry Pi ndi gawo la RFLINK-UART, ndipo njira yolumikizira yolumikizira Chipangizo ndiyofanana, koma ID_ Pini ya Lat siyenera kulumikizidwa, ndi ID0 ndipo ID1 imayikidwa ku manambala a ID osiyanasiyana malinga ndi zofunikira.
ExampPulogalamu:
Wotumiza amatumiza zambiri ku chipangizo #3 ndi chipangizo #1
Wolandira: Example ndi kulandila kosavuta
Kulumikizana kwachindunji ndi sensor
Ngati sensa yanu imathandizira mawonekedwe a UART ndipo mlingo wa Baud umathandizira 9,600 kapena 19,200 , ndiye kuti mukhoza kulumikiza mwachindunji ku mbali ya chipangizo cha RFLINK-UART module, ndipo mukhoza kukonzanso mofulumira komanso mopanda ululu Wopanda zingwe. Sensa yotsatira ya G3 PM2.5 imatengedwa ngati example, tchulani njira yolumikizira iyi
Kenako, chonde konzani gulu lachitukuko (mwina Arduino kapena Raspberry Pi) kuti mulumikizane ndi RO ya gawo la RFLINK-UART Kumbali ina, mutha kuwerenga kufalikira kwa G3 mwanjira ya UART PM2.5 data, zikomo, G3 ili nayo zakwezedwa kukhala gawo la PM2.5 sensing yokhala ndi mphamvu zotumizira opanda zingwe.
Gwiritsani ntchito ma IO Ports
Gawo la RFLINK-UART limapereka ma doko a IO omwe amakulolani kuti mutumize / kuzimitsa malamulo opanda zingwe, ndipo ma Io Ports awa samangopereka kapena kulandira mapeto a gawoli, ndipo mapeto onse amatha kulamulirana. Bola mutasintha voltage za doko la IN kumapeto kulikonse, musintha voltage ya Out port kumapeto ena synchronously. Chonde onani kugwiritsa ntchito kotsatirakuample kufotokoza momwe mungagwiritsire ntchito IO Port kuti muwongolere patali mababu a LED.
