——Kuchokera ku DWIN Developer Forum
Munkhaniyi, tikudziwitsani nkhani yotsegulira yomwe yapambana mphotho ya Devin Developer Forum yogwiritsa ntchito Divin Screen m'gawo latsopanoli - tsamba lawebusayiti ndi T5L Divin Screen serial port kukulitsa mozama (ukadaulo wa Node-RED) .Mainjiniya amagwiritsa ntchito zowonetsera zanzeru za T5L kuti adutse ukadaulo wa Node-RED amangofunika doko lolumikizana ndi intaneti ndikuzindikira kulumikizana kwa data pakati pa skrini ya Diwen ndi tsamba lawebusayiti.Yankholi limazindikira ntchito monga kutumiza ndi kulandira deta, kulumikizana ndi ma chart, ndikuwonetsa zidziwitso zoyambira pakati pa pulogalamu yanzeru ndi tsamba lawebusayiti.
1. Node-RED tsamba lawebusayiti lomwe likuyenda bwino
(1) Pogwiritsa ntchito ukadaulo wa Node-RED, msakatuli amagwiritsidwa ntchito ngati khomo lolowera, kuti msakatuli ndi chinsalu zigwirizane kudzera pa doko la serial kuti azindikire zomwe zikuwonetsedwa.
Kutumiza ndi kulandira deta Tsamba la Tabu
Icon interactive Tab tsamba
Zambiri Zokhudza tsamba latsamba
(2) Zizindikiro zazikulu za kasitomala wa Node-RED ndi motere:
