——Kubva kuDWIN Developer Forum
Muchinyorwa chino, tichakuzivisa kwauri mubairo wakahwina wakavhurika sosi nyaya yeDevin Developer Forum yekushandisa Divin Screen mundima itsva - browser peji rewebhu uye T5L Divin Screen serial port mukuwedzera kwakadzika (Node-RED tekinoroji) .Mainjiniya anoshandisa T5L smart skrini kupfuudza Node-RED tekinoroji inongoda serial port yekubatanidza kuInternet uye kuona kupindirana kwedata pakati peDiwen skrini uye peji rewebhu browser.Iyi mhinduro inoona mabasa akadai sekutumira uye kugamuchira data, kupindirana kwechati, uye ruzivo rwekutanga kuratidza pakati peiyo smart skrini uye peji rewebhu.
1. Node-RED peji rewebhu rinoshanda kuratidza
(1) Uchishandisa tekinoroji yeNode-RED, bhurawuza rinoshandiswa seyekupinda nekupindirana, kuitira kuti bhurawuza uye skrini idyidzane kuburikidza neiyo serial port kuti ione inoenderana basa rinoratidza.
Data kutumira uye kugamuchira Tab peji
Icon interactive Tab peji
Basic ruzivo Tab peji maitiro
(2) Iwo makuru mareferensi makodhi eNode-RED webhu mutengi ndeaya anotevera:
